Swagger is a specification and complete framework implementation for describing, producing, consuming, and visualizing RESTful web services. View demo.

{swagger-express} is a simple and clean solution to integrate swagger with express.

  app.use(swagger.init(app, {
    // Base path of the API
    basePath: 'http://localhost:3000',
    // Folder prefix
    prefix : '/doc',
    // Files containing swagger specs
    apis: ['./api.js'],
    apiVersion : '0.1',
    // Infos to be displayed
    info : {
      title : 'Assemblage',
      description : 'API interface documentation',
      contact : '[email protected]'
    }
  }));

$ npm install -g swagger-express

Configure {swagger-express} as express middleware.

apiVersion -> Your api version.

swaggerVersion -> Swagger version.

basePath -> This is the base path of the server declaring the apis.

prefix -> Url prefix

swaggerUI -> Where is your swagger-ui?

apis -> Define your api array.

var swagger = require('swagger-express');

app.configure(function(){
  ...
  app.use(swagger.init(app, {
    apiVersion: '1.0',
    swaggerVersion: '1.0',
    basePath: 'http://localhost:3000',
    swaggerUI: './public/swagger/',
    apis: ['./api.js', './api.yml']
  }));
  app.use(app.router);
  ...
});

Example 'api.js'

/**
 * @swagger
 * resourcePath: /api
 * description: All about API
 */

/**
 * @swagger
 * path: /login
 * operations:
 *   -  httpMethod: POST
 *      summary: Login with username and password
 *      notes: Returns a user based on username
 *      responseClass: User

exports.login = function (req, res) {
  var user = {};
  user.username = req.param('username');
  user.password = req.param('password');
  res.json(user);
}
