Koaw NPM | npm.io

Koaw

Create APIs using Koa and Waterline. Koaw creates auto-generated CRUD routes, using the co approach and the middleware design pattern.

Install

With npm do:

$ npm install koaw --save

Usage

const Koa = require('koa')
const Koaw = require('koaw')
const Waterline = require('waterline')
const Stores = require('./collections/stores')

// Set collections to ORM
let waterline = new Waterline()
waterline.loadCollection(Stores)

// Create server
let server = new Koa()

// Set new controller
let controller = new Koaw({
  orm: waterline,
  model: 'store'
})

controller
  // Set methods to be used
  .methods('get post put delete')
  // Add middlewares to extend logic using generators
  .before('post', function *(next) { /* some logic */ yield next })
  .after('post', function *(next) { /* some logic */ yield next })
  .before('post put', function *(next) { /* some logic */ yield next })
  .after('post put', function *(next) { /* some logic */ yield next })
  .after('put', function *(next) { /* some logic */ yield next })
  // Register controller
  .register(server)

waterline.initialize({}, function (err) {
  server.listen(4000)
})

The above code registers the following routes:

POST /stores
GET /stores
GET /stores/:id
PUT /stores/:id
DELETE /stores/:id

API

.methods(methods)

Change default methods with an array or whitelisted string. These are default methods: post put get delete.

.override(methods, handler)

Change default handler of auto-generated routes. The methods should be specified with an array or whitelisted string.

.route(methods, path, fn)

Add custom route to given model. The methods should be specified with an array or whitelisted string. For instance, .route('get', 'custom', fn) should generate this route: GET /[collection]/custom

.before(methods, path, fn)

Add a before middleware to one or more methods, both custom routes and auto-generated routes. The methods should be specified with an array or whitelisted string.

.after(methods, path, fn)

Add an after middleware to one or more methods, both custom routes and auto-generated routes. The methods should be specified with an array or whitelisted string.
