express-api-routes v2.0.0

Express.js Server Auto Routing

This module is designed to be used in a Node.js Express.js server. It allows you to build routes/endpoints by simply declaring functions (in your controller files). All functions in the controllers/myPath.js will be available at the endpoint /myPath/{functionName} - they are automatically bound to the express app router. It also allows you to define policy "middleware" that is processed before the request gets to your endpoint.

Node v4

npm install --save express-api-routes

TL;DR

- controllers/
  - user.js
- policies/
  - loggedIn.js
- config/
  - routes.js
- package.json
- app.js

/app.js

const app = require('express')();
const expressApiRoutes = require('expressApiRoutes');

// initialize with a config file
const api = new expressApiRoutes({

  // Logger (winston instance) {optional}
  logger: new winston.Logger,

  // Root directory
  root: __dirname, // defaults to process.mainModule.filename.dir

  // Base route {optional}
  baseRoute: '/api', // defaults to '/'

  // Controllers directory {required} absolute path to controllers dir
  controllers: __dirname + "/controllers", // default if none provided

  // Policies directory {optional} absolute path to policies dir
  policies: __dirname + "/policies", // default if none provided

  // Routes Config Object {optional}
  routes: require('./config/routes'),

  // Express instance {optional}
  app: app, // creates an express app if none provided

});

console.log(api); // { controllers: {..}, policies: {..}, routesMap: [..] }

app.listen(3000);

/controllers/user.js

module.exports = {
  index(req,res,next) {
    // localhost:3000/api/user
    return res.send('Woohoo!');
  },
  someOtherAction(req,res,next) {
    // localhost:3000/api/user/someOtherAction
    return res.send('action, bam!');
  }.
  getUsers(req,res,next) {
    // do some database work...
    return res.send('Send users list!');
  }
};

/policies/loggedIn.js

module.exports = (req,res,next) => {
  console.log('Policy checking login credentials');
  next();
};

/config/routes.js

module.exports = {
  '/users/list': {
    controller: 'user',
    method: 'getUsers',
    policies: ['loggedIn']
  }
};

Now going to your browser localhost:3000/api/users/list will run the function getUsers() from the controller file /controllers/user.js
