Koapi

RESTful API framework based on koa and bookshelf

Writing a RESTful API has never been so easy!

Intro

Koapi is a library for building RESTful APIs in a really simple way.

Installation

npm install koapi

Write your APIs in just ONE minute

Assume you have database below

Table posts
id title contents created_at updated_at
1 Title Contents 2016-8-1 2016-8-1
Table comments
id post_id title contents created_at updated_at
1 1 Title Comment 2016-8-1 2016-8-1

Here we go!

app.js
const { Koapi, router, middlewares, model } = require('koapi')
 
const app = new Koapi();
 
/****************** Connect to database ******************/
model.connect({
  client: 'pg',
  connection: {
    host     : '127.0.0.1',
    user     : 'your_database_user',
    password : 'your_database_password',
    database : 'myapp_test'
  }
})
 
 
class Comment extends model.Base {
  get tableName () { return 'comments' }
  get hasTimestamps () { return true }
}
class Post extends model.Base {
  get tableName () { return 'posts' }
  get hasTimestamps () { return true }
  comments () {
    return this.hasMany(Comment);
  }
}
 
/****************** Implement Routers ******************/
 
const comments = router.resource(Comment, {
  collection: ctx => ctx.state.parents.post.comments()
  setup (route) {
    // method "crud" is a shortcut for "create", "read", "update" and "destroy"
    // YOU CAN ALSO USE MIDDLEWARE in "create", "read", "update", "destroy"    
    route.create(async(ctx, next) => {
      // you can do anything before create
      await next();
      // you can do anything after create
    })
    route.read(/* You can place any middleware here if you need */{
      filterable: ['created_at'], // filterable fields
      sortable: ['created_at'], // sortable fields
    });        
    route.destroy()
  }
})
 
// POST /posts
// GET  /posts
// GET  /posts/:id
// PATCH /posts/:id
// DELETE /posts/:id
const posts = router.resource(Post, route => route.crud()).children(comments)
 
/****************** Run server ******************/
app.use(middlewares.preset('restful'))
app.use(middlewares.routers([ posts ]))
 
app.listen(3000);

run

node ./app
