Installation

``bash
npm i --save adonis5-swagger
`
Compile your code:
`bash
node ace serve --watch
`
Connect all dependences:
`bash
node ace invoke adonis5-swagger
`
* For other configuration, please update the config/swagger.ts.

Sample Usage

* Add new route:
`js
Route.get('/api/hello', 'TestController.hello')
`

* Create TestController using node ace make:controller Test command:

`js
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: 'Bond007@example.com'
* 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 saving and returns
}
}
`

* You can also define the schema in the Models:
`js
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

@column()
public name: string

@column()
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:
`bash
project
├── app
├── config
├── docs
│ ├── controllers
│ │ ├── */.ts
│ │ ├── */.yml
│ └── models
│ ├── */.ts
│ ├── */.yml
`


Best usage

* Create files into docs/swagger, for example docs/swagger/auth.yml may contains:

`YAML
/api/auth/login:
post:
tags:
- Auth
security: []
description: Login
parameters:
- name: credentials
in: body
required: true
schema:
properties:
phone:
type: string
example: '1234567890'
required: true
produces:
- application/json
responses:
200:
description: Success
`
* You can change default settings in config/swagger.ts
* For other sample in YAML and JS format, please refer to this link.

For detail usage, please check the Swagger specification in this SwaggerSpec

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:
`bash
npm i @adonisjs/view
`
Once installed, run the following ace command to setup the package.
`bash
node ace invoke @adonisjs/view
`
Generate new template file using Adonis generator:
`bash
node ace make:view swagger
`

And then add route for custom UI:
`js
Route.get('/', async ({ view }) => {
const specUrl = 'your spec url'
return view.render('swagger', { specUrl })
})
`

Your template should have similar content:
`html













`
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:
`js
const swaggerConfig = {
specFilePath: 'docs/swagger.json'
}
`
And then run adonis command:
`bash
node ace swagger:generate
`
Generated file will be written to by path configured in config.

Swagger modes

This package support two modes:
- PRODUCTION
- RUNTIME

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:
`js
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:
`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

`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
`ts
Server.middleware.registerNamed({
'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.
`ts
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 })
}
}
}
`

Recipes

JWT auth for endpoints

Define JWT component inside your .yaml declaration:
`
components:
securitySchemes:
bearerAuth:
type: http
scheme: bearer
bearerFormat: JWT
`
Or add to your swagger config:
`ts
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:
`
@swagger
/api/users:
post:
security:
- bearerAuth: []
