    Sample Usage

    • Add new route:

      Route.get('/api/hello', 'TestController.hello')
    • Create TestController using node ace make:controller Test command:

    	import { HttpContextContract } from "@ioc:Adonis/Core/HttpContext";
    	import User from "App/Models/User";
    	export default class UsersController {
    		* @swagger
    		* /api/users:
    		* post:
    		*     tags:
    		*       - Users
    		*     requestBody:
    		*       required: true
    		*       content:
    		*         application/json:
    		*           description: User payload
    		*           schema:
    		*             type: object
    		*             properties:
    		*               phone:
    		*                 type: string
    		*                 example: 'James Bond'
    		*                 required: true
    		*               email:
    		*                 type: string
    		*                 example: ''
    		*                 required: true
    		*     produces:
    		*       - application/json
    		*     responses:
    		*       200:
    		*         description: Success
    		*         content:
    		*           application/json:
    		*             schema:
    		*               $ref: '#/components/schemas/User'
    		public async create({ request, response }: HttpContextContract): Promise<User> {
    				// User saving and returns
    • You can also define the schema in the Models:
    		import {DateTime} from 'luxon'
    		import {BaseModel, column} from '@ioc:Adonis/Lucid/Orm'
    		* @swagger
    		* components:
    			* schemas:
    			*      User:
    			*        type: object
    			*        properties:
    			*          name:
    			*            type: string
    			*          email:
    			*            type: string
    		export default class User extends BaseModel {
    		@column({isPrimary: true})
    		public id: number
    		public name: string
    		public email: string
    		@column.dateTime({autoCreate: true})
    		public createdAt: DateTime
    		@column.dateTime({autoCreate: true, autoUpdate: true})
    		public updatedAt: DateTime
    • Or create a separate file containing documentation from the APIs in either TS or YAML formats, sample structure:
      ├── app
      ├── config 
      ├── docs
      │   ├── controllers
      │   │   ├── **/*.ts
      │   │   ├── **/*.yml
      │   └── models
      │       ├── **/*.ts
      │       ├── **/*.yml

    Best usage

    • Create files into docs/swagger, for example docs/swagger/auth.yml may contains:
          - Auth
        security: []
        description: Login
          - name: credentials
            in:  body
            required: true
                  type: string
                  example: '1234567890'
                  required: true
          - application/json
            description: Success
    • You can change default settings in config/swagger.ts
    • For other sample in YAML and JS format, please refer to this link.

    Custom UI

    For using custom ui you should use own build of swagger ui. Current package contains only preconfigured and already built ui bundle. For example, you can use Adonis Edge for rendering ui with custom params.

    First, install edge:

    npm i @adonisjs/view

    Once installed, run the following ace command to setup the package.

    node ace invoke @adonisjs/view

    Generate new template file using Adonis generator:

    node ace make:view swagger

    And then add route for custom UI:

    Route.get('/', async ({ view }) => {
    	const specUrl = 'your spec url'
    	return view.render('swagger', { specUrl })

    Your template should have similar content:

    <!DOCTYPE html>
    	<script src="//"></script>
    	<script src="//"></script>
    	<link rel="stylesheet" href="//"/>
    		window.onload = () => {
    			let ui = SwaggerUIBundle({
    				url: "{{ specUrl }}",
    				dom_id: "#swagger-ui",
    				presets: [
    				plugins: [
    			window.ui = ui
    	<div id="swagger-ui"></div>

    It is the simplest way for using custom swagger ui, but of course you could use Webpack or another bundler tool for bundling your pre configured Swagger ui.

    Build swagger spec file

    You can build swagger spec file the next way:

    Set specFilePath option to your swagger config:

    const swaggerConfig = {
    	specFilePath: 'docs/swagger.json'

    And then run adonis command:

    node ace swagger:generate

    Generated file will be written to by path configured in config.

    Swagger modes

    This package support two modes:


    By default RUNTIME mode enabled. When RUNTIME mode enabled package rebuild swagger spec file on each request. When you use PRODUCTION you should build your swagger spec once and then package will be respond this file content on each request.

    Production using

    For using swagger in production you should make some preparations:

    • Setup swagger config:
    const swaggerConfig = { 
    	mode: process.env.NODE_ENV === 'production' ? 'PRODUCTION' : 'RUNTIME',
    	specFilePath: 'docs/swagger.json'
    • Add post hook for npm build script to your package.json:
    	"scripts": {
    		"build": "npm run compile",
    		"postbuild": "node ace swagger:generate && cp -a docs/ build/docs"
    • Deliver your source code to production server.

    Swagger basic auth

    Package supports auth via basic auth schema. For using auth you should add config in config/swagger.ts

    import Env from '@ioc:Adonis/Core/Env'
    export default {
    	// ...Swagger congig
    	swaggerAuth: {
    		authMiddleware: 'swagger-auth',
    		authCredentials: {
    			login: Env.get('SWAGGER_AUTH_LOGIN'),
    			password: Env.get('SWAGGER_AUTH_PASSWORD')

    Register auth middleware in your start/kernel.ts

      'swagger-auth': 'Adonis/Addons/Swagger/AuthMiddleware',

    That's all. Your swagger docs secured by basic auth.

    Instead of using credentials, you can use function for verifying access in more complex way.

    import Env from '@ioc:Adonis/Core/Env'
    import { verifyDocsAccess } from 'App/Services/Auth/Docs'
    export default {
    	// ...Swagger congig
    	swaggerAuth: {
    		authMiddleware: 'swagger-auth',
    		authCheck: async (login, password) => {
    			return await verifyDocsAccess({ login, password })


    JWT auth for endpoints

    Define JWT component inside your .yaml declaration:

    		type: http
    		scheme: bearer
    		bearerFormat: JWT 

    Or add to your swagger config:

    export default {
    	// ... config options
    	options: {
    		definition: {
    		openapi: '3.0.0',
    		info: {
    			title: 'Application with swagger docs',
    			version: '1.0.0',
    			description: 'My application with swagger docs'
    		components: {
    			securitySchemes: {
    			bearerAuth: {
    				type: "http",
    				scheme: "bearer",
    				bearerFormat: "JWT"
    	//... config options
    } as SwaggerConfig

    Then you can add to your controller auth security option:

    	- bearerAuth: []


    npm i adonis5-swagger
