The entry point file for Ace is stored in the root of your project, and you can execute it as follows. Copy code to clipboard node ace Since the `node` binary cannot run the TypeScript source code directly, we have to keep the ace file in pure JavaScript and use the `.js` extension. Under the hood, the `ace.js` file registers TS Node as an [ESM module loader hook](https://nodejs.org/api/module.html#customization-hooks) to execute the TypeScript code and imports the `bin/console.ts` file. [](https://docs.adonisjs.com/guides/ace/introduction#help-and-list-commands) Help and list commands --------------------------------------------------------------------------------------------------- You can view the list of available commands by running the ace entry point file without any arguments or using the `list` command.

Copy code to clipboard # Disable colors node ace list --no-ansi # Force enable colors node ace list --ansi [](https://docs.adonisjs.com/guides/ace/introduction#creating-command-aliases) Creating command aliases ------------------------------------------------------------------------------------------------------- Command aliases provide a convenience layer to define aliases for commonly used commands. For example, if you often create singular resourceful controllers, you may create an alias for it inside the `adonisrc.ts` file. Copy code to clipboard { commandsAliases: { resource: 'make:controller --resource --singular' } } Once the alias is defined, you can use the alias to run the command. Copy code to clipboard node ace resource admin ### [](https://docs.adonisjs.com/guides/ace/introduction#how-alias-expansion-works) How alias expansion works? * Every time you run a command, Ace will check for aliases inside the `commandsAliases` object. * If an alias exists, the first segment (before the space) will be used to look up the command. * If a command exists, the rest of the alias value segments will be appended to the command name. For example, if you run the following command Copy code to clipboard node ace resource admin --help It will be expanded to Copy code to clipboard make:controller --resource --singular admin --help [](https://docs.adonisjs.com/guides/ace/introduction#running-commands-programmatically) Running commands programmatically ------------------------------------------------------------------------------------------------------------------------- You can use the `ace` service to execute commands programmatically. The ace service is available after the application has been booted. The `ace.exec` method accepts the command name as the first parameter and an array of command line arguments as the second parameter. For example: Copy code to clipboard import ace from '@adonisjs/core/services/ace' const command = await ace.exec('make:controller', [\ 'user',\ '--resource',\ ]) console.log(command.exitCode) console.log(command.result) console.log(command.error) You may use the `ace.hasCommand` method to check if a command exists before executing it.

The flags can be mentioned in any order. You must define flags as class properties and decorate them using the `@flags` decorator. In the following example, we define `resource` and `singular` flags, and both represent a boolean value. Copy code to clipboard import { BaseCommand, flags } from '@adonisjs/core/ace' export default class MakeControllerCommand extends BaseCommands { @flags.boolean() declare resource: boolean @flags.boolean() declare singular: boolean } [](https://docs.adonisjs.com/guides/ace/flags#flag-types) Flag types -------------------------------------------------------------------- Ace allows defining flags for one of the following types. ### [](https://docs.adonisjs.com/guides/ace/flags#boolean-flag) Boolean flag A boolean flag is defined using the `@flags.boolean` decorator. Mentioning the flag will set its value to `true`. Otherwise, the flag value is `undefined`. Copy code to clipboard make:controller --resource # this.resource === true Copy code to clipboard make:controller # this.resource === undefined Copy code to clipboard make:controller --no-resource # this.resource === false The last example shows that the boolean flags can be negated with the `--no-` prefix. By default, the negated option is not shown in the help output. However, you may enable it using the `showNegatedVariantInHelp` option. Copy code to clipboard export default class MakeControllerCommand extends BaseCommands { @flags.boolean({ showNegatedVariantInHelp: true, }) declare resource: boolean } ### [](https://docs.adonisjs.com/guides/ace/flags#string-flag) String flag A string flag accepts a value after the flag name. You may define a string flag using the `@flags.string` method. Copy code to clipboard import { BaseCommand, flags } from '@adonisjs/core/ace' export default class MakeControllerCommand extends BaseCommands { @flags.string() declare model: string } Copy code to clipboard make:controller --model user # this.model = 'user' If the flag value has spaces or special characters, it must be wrapped inside the quotes `""`. Copy code to clipboard make:controller --model blog user # this.model = 'blog' make:controller --model "blog user" # this.model = 'blog user' An error is displayed if the flag is mentioned but no value is provided (even when the flag is optional). Copy code to clipboard make:controller # Works! The optional flag is not mentioned make:controller --model # Error! Missing value ### [](https://docs.adonisjs.com/guides/ace/flags#number-flag) Number flag The parsing of a number flag is similar to the string flag. However, the value is validated to ensure it is a valid number. You can create a number flag using the `@flags.number` decorator. Copy code to clipboard import { BaseCommand, flags } from '@adonisjs/core/ace' export default class MakeUserCommand extends BaseCommands { @flags.number() declare score: number } ### [](https://docs.adonisjs.com/guides/ace/flags#array-flag) Array flag The array flag allows the usage of the flag multiple times when running a command. You can define an array flag using the `@flags.array` method. Copy code to clipboard import { BaseCommand, flags } from '@adonisjs/core/ace' export default class MakeUserCommand extends BaseCommands { @flags.array() declare groups: string[] } Copy code to clipboard make:user --groups=admin --groups=moderators --groups=creators # this.groups = ['admin', 'moderators', 'creators'] [](https://docs.adonisjs.com/guides/ace/flags#flag-name-and-description) Flag name and description -------------------------------------------------------------------------------------------------- By default, the flag name is a dashed case representation of the class property name. However, you can define a custom name via the `flagName` option. Copy code to clipboard @flags.boolean({ flagName: 'server' }) declare startServer: boolean The flag description is displayed on the help screen. You can define it using the `description` option.

We make use of [Playwright](https://playwright.dev/) (a browser automation tool) for interacting with webpages programmatically. Playwright is both a testing framework and a library that exposes JavaScript APIs to interact with the browser. We **do not use the Playwright testing framework** because we are already using Japa, and using multiple testing frameworks inside a single project will only lead to confusion and config bloat. Instead, we will use the [Browser Client](https://japa.dev/docs/plugins/browser-client) plugin from Japa, which integrates nicely with Playwright and offers a great testing experience. [](https://docs.adonisjs.com/guides/testing/browser-tests#setup) Setup ---------------------------------------------------------------------- The first step is to install the following packages from the npm packages registry. npm Copy code to clipboard npm i -D playwright @japa/browser-client ### [](https://docs.adonisjs.com/guides/testing/browser-tests#registering-browser-suite) Registering browser suite Let's start by creating a new test suite for browser tests inside the `adonisrc.ts` file. The test files for the browser suite will be stored inside the `tests/browser` directory. Copy code to clipboard { tests: { suites: [\ {\ files: [\ 'tests/browser/**/*.spec(.ts|.js)'\ ],\ name: 'browser',\ timeout: 300000\ }\ ] } } ### [](https://docs.adonisjs.com/guides/testing/browser-tests#configuring-the-plugin) Configuring the plugin Before you can start writing tests, you must register the `browserClient` plugin within the `tests/bootstrap.ts` file. Copy code to clipboard import { browserClient } from '@japa/browser-client' export const plugins: Config['plugins'] = [\ assert(),\ apiClient(),\ browserClient({\ runInSuites: ['browser']\ }),\ pluginAdonisJS(app)\ ] [](https://docs.adonisjs.com/guides/testing/browser-tests#basic-example) Basic example -------------------------------------------------------------------------------------- Let's create an example test that will open the home page of your AdonisJS application and verify the contents of the page. The [`visit`](https://japa.dev/docs/plugins/browser-client#browser-api) helper opens a new page and visits a URL. The return value is the [page object](https://playwright.dev/docs/api/class-page) .

You may use the `--watch` flag to create a file watcher and re-run tests on every file change. Copy code to clipboard node ace test browser  [](https://docs.adonisjs.com/guides/testing/browser-tests#readingwriting-cookies) Reading/writing cookies --------------------------------------------------------------------------------------------------------- When testing inside a real browser, the cookies are persisted throughout the lifecycle of a [browser context](https://playwright.dev/docs/api/class-browsercontext) . Japa creates a fresh browser context for each test. Therefore, the cookies from one test will not leak onto other tests. However, multiple page visits inside a single test will share the cookies because they use the same `browserContext`. Copy code to clipboard test.group('Home page', () => { test('see welcome message', async ({ visit, browserContext }) => { await browserContext.setCookie('username', 'virk') // The "username" cookie will be sent during the request const homePage = await visit('/') // The "username" cookie will also be sent during this request const aboutPage = await visit('/about') }) }) Similarly, the cookies set by the server can be accessed using the `browserContext.getCookie` method. Copy code to clipboard import router from '@adonisjs/core/services/router' router.get('/', async ({ response }) => { response.cookie('cartTotal', '100') return 'It works!' }) Copy code to clipboard test.group('Home page', () => { test('see welcome message', async ({ visit, browserContext }) => { const page = await visit('/') console.log(await browserContext.getCookie('cartTotal')) }) }) You may use the following methods to read/write encrypted and plain cookies. Copy code to clipboard // Write await browserContext.setEncryptedCookie('username', 'virk') await browserContext.setPlainCookie('username', 'virk') // Read await browserContext.getEncryptedCookie('cartTotal') await browserContext.getPlainCookie('cartTotal') [](https://docs.adonisjs.com/guides/testing/browser-tests#populating-session-store) Populating session store ------------------------------------------------------------------------------------------------------------ If you are using the [`@adonisjs/session`](https://docs.adonisjs.com/guides/basics/session) package to read/write session data in your application, you may also want to use the `sessionBrowserClient` plugin to populate the session store when writing tests. ### [](https://docs.adonisjs.com/guides/testing/browser-tests#setup-1) Setup The first step is registering the plugin inside the `tests/bootstrap.ts` file. Copy code to clipboard import { sessionBrowserClient } from '@adonisjs/session/plugins/browser_client' export const plugins: Config['plugins'] = [\ assert(),\ pluginAdonisJS(app),\ sessionBrowserClient(app)\ ] And then, update the `.env.test` file (create one if it is missing) and set the `SESSON_DRIVER` to `memory`. .env.test Copy code to clipboard SESSION_DRIVER=memory ### [](https://docs.adonisjs.com/guides/testing/browser-tests#writing-session-data) Writing session data You may use the `browserContext.setSession` method to define the session data for the current browser context. All page visits using the same browser context will have access to the same session data. However, the session data will be removed when the browser or the context is closed. Copy code to clipboard test('checkout with cart items', async ({ browserContext, visit }) => { await browserContext.setSession({ cartItems: [\ {\ id: 1,\ name: 'South Indian Filter Press Coffee'\ },\ {\ id: 2,\ name: 'Cold Brew Bags',\ }\ ] }) const page = await visit('/checkout') }) Like the `setSession` method, you may use the `browser.setFlashMessages` method to define flash messages. Copy code to clipboard /** * Define flash messages */ await browserContext.setFlashMessages({ success: 'Post created successfully', }) const page = await visit('/posts/1') /** * Assert the post page shows the flash message * inside ".alert-success" div. */ await page.assertExists(page.locator( 'div.alert-success', { hasText: 'Post created successfully' } )) ### [](https://docs.adonisjs.com/guides/testing/browser-tests#reading-session-data) Reading session data You may read the data inside a session store using the `browserContext.getSession` and `browser.getFlashMessages` methods. These methods will return all the data for the session ID associated with a specific browser context instance. Copy code to clipboard const session = await browserContext.getSession() const flashMessages = await browserContext.getFlashMessages() [](https://docs.adonisjs.com/guides/testing/browser-tests#authenticating-users) Authenticating users ---------------------------------------------------------------------------------------------------- If you are using the `@adonisjs/auth` package to authenticate users in your application, you may use the `authBrowserClient` Japa plugin to authenticate users when making HTTP requests to your application. The first step is registering the plugin inside the `tests/bootstrap.ts` file. tests/bootstrap.ts Copy code to clipboard import { authBrowserClient } from '@adonisjs/auth/plugins/browser_client' export const plugins: Config['plugins'] = [\ assert(),\ pluginAdonisJS(app),\ authBrowserClient(app)\ ] If you are using session-based authentication, make sure to also set up the session plugin. See [Populating session store - Setup](https://docs.adonisjs.com/guides/testing/browser-tests#setup-1) . That's all. Now, you may login users using the `loginAs` method. The method accepts the user object as the only argument and marks the user as logged in the current browser context. All page visits using the same browser context will have access to the logged-in user. However, the user session will be destroyed when the browser or the context is closed. Copy code to clipboard import User from '#models/user' test('get payments list', async ({ browserContext, visit }) => { const user = await User.create(payload) await browserContext.loginAs(user) const page = await visit('/dashboard') }) The `loginAs` method uses the default guard configured inside the `config/auth.ts` file for authentication. However, you may specify a custom guard using the `withGuard` method. For example: Copy code to clipboard const user = await User.create(payload) await browserContext .withGuard('admin') .loginAs(user) [](https://docs.adonisjs.com/guides/testing/browser-tests#the-route-helper) The route helper -------------------------------------------------------------------------------------------- You may use the `route` helper from the TestContext to create a URL for a route. Using the route helper ensures that whenever you update your routes, you do not have to come back and fix all the URLs inside your tests. The `route` helper accepts the same set of arguments accepted by the global template method [route](https://docs.adonisjs.com/guides/basics/routing#url-builder) .

To protect against CSRF attacks, you should define a hidden input field holding the CSRF token value that only your website can generate and verify. Hence, the form submissions triggered by the malicious website will fail. ### [](https://docs.adonisjs.com/guides/security/securing-ssr-applications#protecting-forms) Protecting forms Once you configure the `@adonisjs/shield` package, all form submissions without a CSRF token will automatically fail. Therefore, you must use the `csrfField` edge helper to define a hidden input field with the CSRF token. **Edge helper** Copy code to clipboard **Output HTML** Copy code to clipboard During the form submission, the `shield_middleware` will automatically verify the `_csrf` token, only allowing the form submissions with a valid CSRF token. ### [](https://docs.adonisjs.com/guides/security/securing-ssr-applications#handling-exceptions) Handling exceptions Shield raises an `E_BAD_CSRF_TOKEN` exception when the CSRF token is missing or invalid. By default, AdonisJS will capture the exception and redirect the user back to the form with an error flash message. You can access the flash message as follows inside an edge template. Copy code to clipboard @error('E_BAD_CSRF_TOKEN')
{{ $message }}
@end You can also self-handle the `E_BAD_CSRF_TOKEN` exception inside the [global exception handler](https://docs.adonisjs.com/guides/basics/exception-handling#handling-exceptions) as follows.

If your application has routes that accept form submissions via an API, you might want to exempt them. For more advanced use cases, you may register a function to exempt specific routes dynamically. Copy code to clipboard { exceptRoutes: (ctx) => { // exempt all routes starting with /api/ return ctx.request.url().includes('/api/') } } enableXsrfCookie When enabled, Shield will store the CSRF token inside an encrypted cookie named `XSRF-TOKEN`, which can be read by the frontend JavaScript code. This allows frontend request libraries like Axios to read the `XSRF-TOKEN` automatically and set it as a `X-XSRF-TOKEN` header when making Ajax requests without server-rendered forms. You must keep the `enableXsrfCookie` disabled if you are not triggering Ajax requests programmatically. methods An array of HTTP methods to protect.

The API client plugin is a stateless request library similar to `Axios` or `fetch` but more suited for testing. If you want to test your web apps inside a real browser and interact with them programmatically, we recommend using the [Browser client](https://docs.adonisjs.com/guides/testing/browser-tests) that uses Playwright for testing.

[](https://docs.adonisjs.com/guides/testing/http-tests#open-api-testing) Open API testing ----------------------------------------------------------------------------------------- The assertion and API client plugins allow you to use Open API spec files for writing assertions. Instead of manually testing the response against a fixed payload, you may use a spec file to test the shape of the HTTP response. It is a great way to keep your Open API spec and server responses in sync. Because if you remove a certain endpoint from the spec file or change the response data shape, your tests will fail. ### [](https://docs.adonisjs.com/guides/testing/http-tests#registering-schema) Registering schema AdonisJS does not offer tooling for generating Open API schema files from code. You may write it by hand or use graphical tools to create it.

Copy code to clipboard { providers: [\ // ...other providers\ () => import('@adonisjs/ally/ally_provider')\ ] } 3. Create the `config/ally.ts` file. This file contains the configuration settings for selected OAuth providers. 4. Defines the environment variables to store `CLIENT_ID` and `CLIENT_SECRET` for selected OAuth providers. [](https://docs.adonisjs.com/guides/authentication/social-authentication#configuration) Configuration ----------------------------------------------------------------------------------------------------- The `@adonisjs/ally` package configuration is stored inside the `config/ally.ts` file.

The callback URL must be registered with the OAuth service provider. For example: If you are using GitHub, you must log in to your GitHub account, [create a new app](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/creating-an-oauth-app) and define the callback URL using the GitHub interface. Also, you must register the same callback URL within the `config/ally.ts` file using the `callbackUrl` property. [](https://docs.adonisjs.com/guides/authentication/social-authentication#usage) Usage ------------------------------------------------------------------------------------- Once the package has been configured, you can interact with Ally APIs using the `ctx.ally` property. You can switch between the configured auth providers using the `ally.use()` method.

You can perform the redirect using the `.redirect()` method. Copy code to clipboard router.get('/github/redirect', ({ ally }) => { return ally.use('github').redirect() }) You can pass a callback function to define custom scopes or query string values during the redirect.

It is a simple and efficient way to send real-time updates to the client, such as notifications, live chat messages, or any other type of real-time data. The data transmission occurs only from server to client, not the other way around. You have to use a form or a fetch request to achieve client to server communication. [](https://docs.adonisjs.com/guides/digging-deeper/transmit#installation) Installation -------------------------------------------------------------------------------------- Install and configure the package using the following command : Copy code to clipboard node ace add @adonisjs/transmit See steps performed by the add command 1. Installs the `@adonisjs/transmit` package using the detected package manager. 2. Registers the `@adonisjs/transmit/transmit_provider` service provider inside the `adonisrc.ts` file. 3. Creates a new `transmit.ts` file inside the `config` directory. You will also have to install the Transmit client package to listen for events on the client-side. Copy code to clipboard npm install @adonisjs/transmit-client [](https://docs.adonisjs.com/guides/digging-deeper/transmit#configuration) Configuration ---------------------------------------------------------------------------------------- The configuration for the transmit package is stored within the `config/transmit.ts` file. See also: [Config stub](https://github.com/adonisjs/transmit/blob/main/stubs/config/transmit.stub) Copy code to clipboard import { defineConfig } from '@adonisjs/transmit' export default defineConfig({ pingInterval: false, transport: null, }) pingInterval The interval used to send ping messages to the client. The value is in milliseconds or using a string `Duration` format (i.e: `10s`). Set to `false` to disable ping messages. transport Transmit supports syncing events across multiple servers or instances. You can enable the feature by referencing the wanted transport layer (only `redis` is supported for now). Set to `null` to disable syncing. Copy code to clipboard import env from '#start/env' import { defineConfig } from '@adonisjs/transmit' import { redis } from '@adonisjs/transmit/transports' export default defineConfig({ transport: { driver: redis({ host: env.get('REDIS_HOST'), port: env.get('REDIS_PORT'), password: env.get('REDIS_PASSWORD'), keyPrefix: 'transmit', }) } }) Ensure you have `ioredis` installed when using the `redis` transport. [](https://docs.adonisjs.com/guides/digging-deeper/transmit#register-routes) Register Routes -------------------------------------------------------------------------------------------- You have to register the transmit routes to allow the client to connect to the server. The routes are registered manually. start/routes.ts Copy code to clipboard import transmit from '@adonisjs/transmit/services/main' transmit.registerRoutes() You can also register each route manually by binding the controller by hand. start/routes.ts Copy code to clipboard const EventStreamController = () => import('@adonisjs/transmit/controllers/event_stream_controller') const SubscribeController = () => import('@adonisjs/transmit/controllers/subscribe_controller') const UnsubscribeController = () => import('@adonisjs/transmit/controllers/unsubscribe_controller') router.get('/__transmit/events', [EventStreamController]) router.post('/__transmit/subscribe', [SubscribeController]) router.post('/__transmit/unsubscribe', [UnsubscribeController]) If you want to modify the route definition, for example, to use the [`Rate Limiter`](https://docs.adonisjs.com/guides/security/rate-limiting) and auth middleware to avoid abuse of some transmit routes, you can either change the route definition or pass a callback to the `transmit.registerRoutes` method. start/routes.ts Copy code to clipboard import transmit from '@adonisjs/transmit/services/main' transmit.registerRoutes((route) => { // Ensure you are authenticated to register your client if (route.getPattern() === '__transmit/events') { route.middleware(middleware.auth()) return } // Add a throttle middleware to other transmit routes route.use(throttle) }) [](https://docs.adonisjs.com/guides/digging-deeper/transmit#channels) Channels ------------------------------------------------------------------------------ Channels are used to group events. For example, you can have a channel for notifications, another for chat messages, and so on. They are created on the fly when the client subscribes to them. ### [](https://docs.adonisjs.com/guides/digging-deeper/transmit#channel-names) Channel Names Channel names are used to identify the channel. They are case-sensitive and must be a string. You cannot use any special characters or spaces in the channel name except `/`. The following are some examples of valid channel names: Copy code to clipboard import transmit from '@adonisjs/transmit/services/main' transmit.broadcast('global', { message: 'Hello' }) transmit.broadcast('chats/1/messages', { message: 'Hello' }) transmit.broadcast('users/1', { message: 'Hello' }) Channel names use the same syntax as route in AdonisJS but are not related to them. You can freely define a http route and a channel with the same key. ### [](https://docs.adonisjs.com/guides/digging-deeper/transmit#channel-authorization) Channel Authorization You can authorize or reject a connection to a channel using the `authorize` method. The method receives the channel name and the `HttpContext`. It must return a boolean value. start/transmit.ts Copy code to clipboard import transmit from '@adonisjs/transmit/services/main' import Chat from '#models/chat' import type { HttpContext } from '@adonisjs/core/http' transmit.authorize<{ id: string }>('users/:id', (ctx: HttpContext, { id }) => { return ctx.auth.user?.id === +id }) transmit.authorize<{ id: string }>('chats/:id/messages', async (ctx: HttpContext, { id }) => { const chat = await Chat.findOrFail(+id) return ctx.bouncer.allows('accessChat', chat) }) [](https://docs.adonisjs.com/guides/digging-deeper/transmit#broadcasting-events) Broadcasting Events ---------------------------------------------------------------------------------------------------- You can broadcast events to a channel using the `broadcast` method. The method receives the channel name and the data to send. Copy code to clipboard import transmit from '@adonisjs/transmit/services/main' transmit.broadcast('global', { message: 'Hello' }) You can also broadcast events to any channel except one using the `broadcastExcept` method. The method receives the channel name, the data to send, and the UID you want to ignore. Copy code to clipboard transmit.broadcastExcept('global', { message: 'Hello' }, 'uid-of-sender') ### [](https://docs.adonisjs.com/guides/digging-deeper/transmit#syncing-across-multiple-servers-or-instances) Syncing across multiple servers or instances By default, broadcasting events works only within the context of an HTTP request. However, you can broadcast events from the background using the `transmit` service if you register a `transport` in your configuration. The transport layer is responsible for syncing events across multiple servers or instances. It works by broadcasting any events (like broadcasted events, subscriptions, and un-subscriptions) to all connected servers or instances using a `Message Bus`. The server or instance responsible for your client connection will receive the event and broadcast it to the client. [](https://docs.adonisjs.com/guides/digging-deeper/transmit#transmit-client) Transmit Client -------------------------------------------------------------------------------------------- You can listen for events on the client-side using the `@adonisjs/transmit-client` package. The package provides a `Transmit` class. The client use the [`EventSource`](https://developer.mozilla.org/en-US/docs/Web/API/EventSource) API by default to connect to the server. Copy code to clipboard import { Transmit } from '@adonisjs/transmit-client' export const transmit = new Transmit({ baseUrl: window.location.origin }) You should create only one instance of the `Transmit` class and reuse it throughout your application. ### [](https://docs.adonisjs.com/guides/digging-deeper/transmit#configuring-the-transmit-instance) Configuring the Transmit Instance The `Transmit` class accepts an object with the following properties: baseUrl The base URL of the server. The URL must include the protocol (http or https) and the domain name. uidGenerator A function that generates a unique identifier for the client. The function must return a string. It defaults to `crypto.randomUUID`. eventSourceFactory A function that creates a new `EventSource` instance. It defaults to the WebAPI [`EventSource`](https://developer.mozilla.org/en-US/docs/Web/API/EventSource) . You need to provide a custom implementation if you want to use the client on `Node.js`, `React Native` or any other environment that does not support the `EventSource` API. eventTargetFactory A function that creates a new `EventTarget` instance. It defaults to the WebAPI [`EventTarget`](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget) . You need to provide a custom implementation if you want to use the client on `Node.js`, `React Native` or any other environment that does not support the `EventTarget` API. Return `null` to disable the `EventTarget` API. httpClientFactory A function that creates a new `HttpClient` instance. It is mainly used for testing purposes. beforeSubscribe A function that is called before subscribing to a channel. It receives the channel name and the `Request` object sent to the server. Use this function to add custom headers or modify the request object. beforeUnsubscribe A function that is called before unsubscribing from a channel. It receives the channel name and the `Request` object sent to the server. Use this function to add custom headers or modify the request object. maxReconnectAttempts The maximum number of reconnection attempts. It defaults to `5`. onReconnectAttempt A function that is called before each reconnection attempt and receives the number of attempts made so far. Use this function to add custom logic. onReconnectFailed A function that is called when the reconnection attempts fail. Use this function to add custom logic. onSubscribeFailed A function that is called when the subscription fails. It receives the `Response` object. Use this function to add custom logic. onSubscription A function that is called when the subscription is successful. It receives the channel name. Use this function to add custom logic. onUnsubscription A function that is called when the unsubscription is successful. It receives the channel name. Use this function to add custom logic. ### [](https://docs.adonisjs.com/guides/digging-deeper/transmit#creating-a-subscription) Creating a Subscription You can create a subscription to a channel using the `subscription` method. The method receives the channel name. Copy code to clipboard const subscription = transmit.subscription('chats/1/messages') await subscription.create() The `create` method registers the subscription on the server. It returns a promise that you can `await` or `void`. If you don't call the `create` method, the subscription will not be registered on the server, and you will not receive any events. ### [](https://docs.adonisjs.com/guides/digging-deeper/transmit#listening-for-events) Listening for Events You can listen for events on the subscription using the `onMessage` method that receives a callback function. You can call the `onMessage` method multiple times to add different callbacks. Copy code to clipboard subscription.onMessage((data) => { console.log(data) }) You can also listen to a channel only once using the `onMessageOnce` method which receives a callback function. Copy code to clipboard subscription.onMessageOnce(() => { console.log('I will be called only once') }) ### [](https://docs.adonisjs.com/guides/digging-deeper/transmit#stop-listening-for-events) Stop Listening for Events The `onMessage` and `onMessageOnce` methods return a function that you can call to stop listening for a specific callback. Copy code to clipboard const stopListening = subscription.onMessage((data) => { console.log(data) }) // Stop listening stopListening() ### [](https://docs.adonisjs.com/guides/digging-deeper/transmit#deleting-a-subscription) Deleting a Subscription You can delete a subscription using the `delete` method. The method returns a promise that you can `await` or `void`. This method will unregister the subscription on the server. Copy code to clipboard await subscription.delete() [](https://docs.adonisjs.com/guides/digging-deeper/transmit#avoiding-gzip-interference) Avoiding GZip Interference ------------------------------------------------------------------------------------------------------------------ When deploying applications that use `@adonisjs/transmit`, it’s important to ensure that GZip compression does not interfere with the `text/event-stream` content type used by Server-Sent Events (SSE). Compression applied to `text/event-stream` can cause connection issues, leading to frequent disconnects or SSE failures. If your deployment uses a reverse proxy (such as Traefik or Nginx) or other middleware that applies GZip, ensure that compression is disabled for the `text/event-stream` content type. ### [](https://docs.adonisjs.com/guides/digging-deeper/transmit#example-configuration-for-traefik) Example Configuration for Traefik Copy code to clipboard traefik.http.middlewares.gzip.compress=true traefik.http.middlewares.gzip.compress.excludedcontenttypes=text/event-stream traefik.http.routers.my-router.middlewares=gzip * * * [Digging deeper\ \ Repl](https://docs.adonisjs.com/guides/digging-deeper/repl) [Ace commands\ \ Introduction](https://docs.adonisjs.com/guides/ace/introduction) © 2025 AdonisJS [Edit this page](https://github.com/adonisjs/v6-docs/blob/main/content/docs/digging_deeper/transmit.md) --- # Terminal UI (Ace commands) | AdonisJS Documentation Toggle docs menu Terminal UI [](https://docs.adonisjs.com/guides/ace/terminal-ui#terminal-ui) Terminal UI ============================================================================ Ace terminal UI is powered by the [@poppinss/cliui](https://github.com/poppinss/cliui) package. The package exports helpers to display logs, render tables, render animated tasks UI, and much more. The terminal UI primitives are built with testing in mind.

Disk full')) this.logger.fatal(new Error('Unable to write. Disk full')) } } ### [](https://docs.adonisjs.com/guides/ace/terminal-ui#adding-prefix-and-suffix) Adding prefix and suffix Using the options object, you may define the `prefix` and `suffix` for the log message. The prefix and suffix are displayed with lower opacity. Copy code to clipboard this.logger.info('installing packages', { suffix: 'npm i --production' }) this.logger.info('installing packages', { prefix: process.pid }) ### [](https://docs.adonisjs.com/guides/ace/terminal-ui#loading-animation) Loading animation A log message with loading animation appends animated three dots (...) to the message. You may update the log message using the `animation.update` method and stop the animation using the `animation.stop` method. Copy code to clipboard const animation = this.logger.await('installing packages', { suffix: 'npm i' }) animation.start() // Update the message animation.update('unpacking packages', { suffix: undefined }) // Stop animation animation.stop() ### [](https://docs.adonisjs.com/guides/ace/terminal-ui#logger-actions) Logger actions Logger actions can display the state of action with consistent styling and colors. You may create an action using the `logger.action` method. The method accepts the action title as the first parameter. Copy code to clipboard const createFile = this.logger.action('creating config/auth.ts') try { await performTasks() createFile.displayDuration().succeeded() } catch (error) { createFile.failed(error) } You can mark an action as either `succeeded`, `failed`, or `skipped`. Copy code to clipboard action.succeeded() action.skipped('Skip reason') action.failed(new Error()) [](https://docs.adonisjs.com/guides/ace/terminal-ui#formatting-text-with-ansi-colors) Formatting text with ANSI colors ---------------------------------------------------------------------------------------------------------------------- Ace uses [kleur](https://www.npmjs.com/package/kleur) for formatting text with ANSI colors. Using the `this.colors` property, you can access kleur's chained API. Copy code to clipboard this.colors.red('[ERROR]') this.colors.bgGreen().white(' CREATED ') [](https://docs.adonisjs.com/guides/ace/terminal-ui#rendering-tables) Rendering tables -------------------------------------------------------------------------------------- A table can be created using the `this.ui.table` method. The method returns an instance of the `Table` class that you can use to define the table head and rows. Copy code to clipboard import { BaseCommand } from '@adonisjs/core/ace' export default class GreetCommand extends BaseCommand { async run() { const table = this.ui.table() table .head([\ 'Migration',\ 'Duration',\ 'Status',\ ]) .row([\ '1590591892626_tenants.ts',\ '2ms',\ 'DONE'\ ]) .row([\ '1590595949171_entities.ts',\ '2ms',\ 'DONE'\ ]) .render() } } You may apply color transforms to any value when rendering the table. For example: Copy code to clipboard table.row([\ '1590595949171_entities.ts',\ '2',\ this.colors.green('DONE')\ ]) ### [](https://docs.adonisjs.com/guides/ace/terminal-ui#right-align-columns) Right-align columns You may right-align the columns by defining them as objects and using the hAlign property. Make sure to also right-align the header column. Copy code to clipboard table .head([\ 'Migration',\ 'Batch'\ {\ content: 'Status',\ hAlign: 'right'\ },\ ]) table.row([\ '1590595949171_entities.ts',\ '2',\ {\ content: this.colors.green('DONE'),\ hAlign: 'right'\ }\ ]) ### [](https://docs.adonisjs.com/guides/ace/terminal-ui#full-width-rendering) Full-width rendering By default, tables are rendered with width `auto`, taking only the space required by the contents of each column. However, you may render tables at full-width (taking all the terminal space) using the `fullWidth` method. In full-width mode: * We will render all columns as per the size of the content. * Except for the first column, which takes all the available space. Copy code to clipboard table.fullWidth().render() You may change the column index for the fluid column (the one that takes all the space) by calling the `table.fluidColumnIndex` method. Copy code to clipboard table .fullWidth() .fluidColumnIndex(1) [](https://docs.adonisjs.com/guides/ace/terminal-ui#printing-stickers) Printing stickers ---------------------------------------------------------------------------------------- Stickers allow you to render content inside a box with a border. They are helpful when you want to draw the user's attention to an essential piece of information. You can create an instance of a sticker using the `this.ui.sticker` method. Copy code to clipboard import { BaseCommand } from '@adonisjs/core/ace' export default class GreetCommand extends BaseCommand { async run() { const sticker = this.ui.sticker() sticker .add('Started HTTP server') .add('') .add(`Local address: ${this.colors.cyan('http://localhost:3333')}`) .add(`Network address: ${this.colors.cyan('http://192.168.1.2:3333')}`) .render() } } If you want to display a set of instructions inside a box, you can use the `this.ui.instructions` method. Each line in the instructions output will be prefixed with an arrow sign `>`. [](https://docs.adonisjs.com/guides/ace/terminal-ui#rendering-tasks) Rendering tasks ------------------------------------------------------------------------------------ The tasks widget provides an excellent UI for sharing the progress of multiple time-taking tasks. The widget has the following two rendering modes: * In `minimal` mode, the UI for the currently running task is expanded to show one log line at a time. * In `verbose` mode, each log statement is rendered in its line. The verbose renderer must be used for debugging tasks. You can create an instance of the tasks widget using the `this.ui.tasks` method. Copy code to clipboard import { BaseCommand } from '@adonisjs/core/ace' export default class GreetCommand extends BaseCommand { async run() { const tasks = this.ui.tasks() // ... rest of the code to follow } } Individual tasks are added using the `tasks.add` method. The method accepts the task title as the first parameter and the implementation callback as the second parameter. You must return the status of the task from the callback. All return values are considered success messages until you wrap them inside the `task.error` method or throw an exception inside the callback. Copy code to clipboard import { BaseCommand } from '@adonisjs/core/ace' export default class GreetCommand extends BaseCommand { async run() { const tasks = this.ui.tasks() await tasks .add('clone repo', async (task) => { return 'Completed' }) .add('update package file', async (task) => { return task.error('Unable to update package file') }) .add('install dependencies', async (task) => { return 'Installed' }) .run() } } ### [](https://docs.adonisjs.com/guides/ace/terminal-ui#reporting-task-progress) Reporting task progress Instead of writing the task progress messages to the console, it is recommended to call the `task.update` method. The `update` method displays the latest log message using the `minimal` renderer and logs all messages using the `verbose` renderer. Copy code to clipboard const sleep = () => new Promise

For example: The ICU messages syntax [does not support nested data sets](https://github.com/formatjs/formatjs/pull/2039#issuecomment-951550150) , and hence, you can only access properties from a flat object during interpolation. Copy code to clipboard { "greeting": "Hello { username }" } Copy code to clipboard {{ t('messages.greeting', { username: 'Virk' }) }} You can also write HTML within the messages. However, use three [curly braces](https://edgejs.dev/docs/interpolation#escaped-html-output) within the Edge templates to render HTML without escaping it.

" } Copy code to clipboard {{{ t('messages.greeting', { username: 'Virk' }) }}} ### [](https://docs.adonisjs.com/guides/digging-deeper/i18n#number-format) Number format You can format numeric values within the translation messages using the `{key, type, format}` syntax. In the following example: * The `amount` is the runtime value. * The `number` is the formatting type. * And the `::currency/USD` is the currency format with a [number skeleton](https://unicode-org.github.io/icu/userguide/format_parse/numbers/skeletons.html#overview) Copy code to clipboard { "bagel_price": "The price of this bagel is {amount, number, ::currency/USD}" } Copy code to clipboard {{ t('bagel_price', { amount: 2.49 }) }} Copy code to clipboard The price of this bagel is $2.49 The following are examples of using the `number` format with different formatting styles and number skeletons.

For example: In the following example, we use YAML over JSON since writing multiline text in YAML is easier. Copy code to clipboard cart_summary: "You have {itemsCount, plural, =0 {no items} one {1 item} other {# items} } in your cart" Copy code to clipboard {{ t('messages.cart_summary', { itemsCount: 1 }) }} Copy code to clipboard You have 1 item in your cart The `#` is a special token to be used as a placeholder for the numeric value. It will be formatted as `{key, number}`. Copy code to clipboard {{ t('messages.cart_summary', { itemsCount: 1000 }) }} {{-- Output --}} {{-- You have 1,000 items in your cart --}} The plural rule uses the `{key, plural, matches}` syntax. The `matches` is a literal value matched to one of the following plural categories. | Category | Description | | --- | --- | | `zero` | This category is used for languages with grammar specialized specifically for zero number of items. (Examples are Arabic and Latvian) | | `one` | This category is used for languages with grammar explicitly specialized for one item. Many languages, but not all, use this plural category.

(Examples are Arabic and Welsh.) | | `few` | This category is used for languages with grammar explicitly specialized for a small number of items. For some languages, this is used for 2-4 items, for some 3-10 items, and other languages have even more complex rules. | | `many` | This category is used for languages with specialized grammar for a more significant number of items. (Examples are Arabic, Polish, and Russian.) | | `other` | This category is used if the value doesn't match one of the other plural categories.

Using MJML for email markup
MJML is a markup language for creating emails without writing all the complex HTML to make your emails look good in every email client.
The first step is to install the [mjml](https://npmjs.com/mjml)
package from npm.
Copy code to clipboard
npm i mjml
Once done, you can write MJML markup inside your Edge templates by wrapping it inside the `@mjml` tag.
Since the output of MJML contains the `html`, `head`, and `body` tags, it is unnecessary to define them within your Edge templates.

6. Create a `./inertia/css/app.css` file with the content needed to style the `inertia_layout.edge` view.
7. Create a `./inertia/tsconfig.json` file to differentiate between the server and client-side TypeScript configuration.
8. Create a `./inertia/app/app.ts` for bootstrapping Inertia and your frontend framework.
9. Create a `./inertia/pages/home.{tsx|vue|svelte}` file to render the home page of your application.
10. Create a `./inertia/pages/server_error.{tsx|vue|svelte}` and `./inertia/pages/not_found.{tsx|vue|svelte}` files to render the error pages.
11. Add the correct vite plugin to compile your frontend framework in the `vite.config.ts` file.
12. Add a dumb route at `/` in your `start/routes.ts` file to render the home page with Inertia as an example.
13. Install packages based on the selected frontend framework.
Once done, you should be ready to use Inertia in your AdonisJS application. Start your development server, and visit `localhost:3333` to see the home page rendered using Inertia with your selected frontend framework.
**Read the [Inertia official documentation](https://inertiajs.com/)
**.
Inertia is a backend-agnostic library. We just created an adapter to make it work with AdonisJS. You should be familiar with the Inertia concepts before reading this documentation.
**We will only cover AdonisJS's specific parts in this documentation.**

Client-side entrypoint
--------------------------------------------------------------------------------------------------------------
If you used the `configure` or `add` command, the package will have created an entrypoint file at `inertia/app/app.ts` so you can skip this step.
Basically, this file will be the main entrypoint for your frontend application and will be used to bootstrap Inertia and your frontend framework. This file should be the entrypoint loaded by your root Edge template with the `@vite` tag.
