adonis-swagger-jsdoc v1.0.3
swagger-jsdoc
swagger-jsdoc enables to integrate Swagger using JSDoc. This is a wrapper package that allows you to use the package the adonis way. The package has been updated to support the latest adonisjs 4.1
Supported Swagger Versions
- 2.0
Install
$ npm install adonis-swagger-jsdoc --save
Quick Start
swagger-jsdoc returns the validated swagger specification as JSON.
register adonis-swagger-jsdoc inside app.js file inside the bootstrap folder in the root of your application using the following code inside the providers json
'adonis-swagger-jsdoc/providers/SwaggerjsdocProvider',
and also placing the following code inside the alias of provider.json
Swagger: 'Dent/Custom/SwaggerjsdocProvider'
Then inside your routes.js file initiate addonis-swagger-jsdoc using the following code
var swaggerJSDoc = use('Swagger');
var options = {
swaggerDefinition: {
info: {
title: 'Hello World', // Title (required)
version: '1.0.0', // Version (required)
},
},
apis: ['./routes.js'], // Path to the API docs
};
// Initialize swagger-jsdoc -> returns validated swagger spec in json format
var swaggerSpec = swaggerJSDoc(options);
At this time you can do with the swaggerSpec whatever you want. The simplest way would be serving it straight to the outside world:
app.get('/swagger.json', function(req, res) {
res.setHeader('Content-Type', 'application/json');
res.send(swaggerSpec);
});
You could also use a framework like swagger-tools to serve the spec and a swagger-ui.
How to document the API
The API can now be documented in JSDoc-style with swagger spec in YAML.
/**
* @swagger
* /login:
* post:
* description: Login to the application
* produces:
* - application/json
* parameters:
* - name: username
* description: Username to use for login.
* in: formData
* required: true
* type: string
* - name: password
* description: User's password.
* in: formData
* required: true
* type: string
* responses:
* 200:
* description: login
*/
app.post('/login', function(req, res) {
res.json(req.body);
});
Re-using Model Definitions
A model may be the same for multiple endpoints (Ex. User POST,PUT responses). In place of writing (or copy and pasting) the same code into multiple locations, which can be error prone when adding a new field to the schema. You can define a model and re-use it across multiple endpoints. You can also reference another model and add fields.
/**
* @swagger
* definition:
* NewUser:
* type: object
* required:
* - username
* - password
* properties:
* username:
* type: string
* password:
* type: string
* format: password
* User:
* allOf:
* - $ref: '#/definitions/NewUser'
* - required:
* - id
* - properties:
* id:
* type: integer
* format: int64
*/
/**
* @swagger
* /users:
* get:
* description: Returns users
* produces:
* - application/json
* responses:
* 200:
* description: users
* schema:
* type: array
* items:
* $ref: '#/definitions/User'
*/
app.get('/users', function(req, res) {
res.json([ {
id: 1,
username: 'jsmith',
}, {1
id: 2,
username: 'jdoe',
} ]);
});
/**
* @swagger
* /users:
* post:
* description: Returns users
* produces:
* - application/json
* parameters:
* - name: user
* description: User object
* in: body
* required: true
* type: string
* schema:
* $ref: '#/definitions/NewUser'
* responses:
* 200:
* description: users
* schema:
* $ref: '#/definitions/User'
*/
app.post('/users', function(req, res) {
// Generate ID
req.body.id = Math.floor(Math.random() * 100) * 1
res.json(req.body);
});
Load external definitions
You can load external definitions or paths after swaggerJSDoc()
function.
// Initialize swagger-jsdoc -> returns validated swagger spec in json format
var swaggerSpec = swaggerJSDoc(options);
// load external schema json
swaggerSpec.definitions.in_login = require("config/schemajson/in.login.schema.json");
swaggerSpec.definitions.out_login = require("config/schemajson/out.login.schema.json");
// or set manual paths
swaggerSpec.paths["api/v1/cool"] = {"get" : { ... } }
};
Example App
There is an example app in the example subdirectory. To use it you can use the following commands:
$ git clone https://github.com/Surnet/swagger-jsdoc.git
$ cd swagger-jsdoc
$ npm install
$ npm start
The swagger spec will be served at http://localhost:3000/swagger.json
