Tiny RESTful API frameworks - TAPI

• This is a tiny frameworks for RESTful API applications.
• TAPI bases on express.js.
• Designed for applications with express and mongoose, but not depends on mongoose.

Install

npm isntall tapi

Simple Usage

Suppose your files tree like this:

-lib
|-controllers
 |-Users.js
|-medols
 |-Users.js
-app.js

then, in app.js:

var express = require('express')
, tapi = require('tapi')
, mongoose = require('mongoose')
, app = express();

mongoose.connect('mongodb://user:pw@localhost/test');

tapi.config({
    libs: './lib',
    prefix: '/api/version-1/'
});

app.use(app.router);
app.api('/user/:id?', 'user.show', 'GET');
app.listen(3000);

in lib/controllers/Users.js:

exports.show = function(req, res, next) {
    this.send(200, this.medol);
};

in lib/medols/Users.js:

var mongoose = require('mongoose')
, Schema = mongoose.Schema
, UsersSchema = new Schema({
    nickname: String
});

module.exports = mongoose.model('Users', UsersSchema);

when request '/api/version-1/user/1234', will responses default json format like this:

{
    "request": "/api/version-1/user/1234",
    "code": 200,
    "message": "OK",
    "data": {
        "nickname": "XXXXXX"
        "_id": [57, 56 ...]
    }
}

Main Functions

tapi.config(options)

tapi.config({
    libs: String,  //dir path of controllers and medols, default "./lib"
    prefix: String //prefix for the dir path of route, default "/"
})

app.api(route, controller / controller.action [, method])

app.api('/user/:id?', 'Users'); // only controller, default action mapping will be used, see `Actions Mapping` below.
app.api('/posts/:id', 'Posts.show') // no HTTP method, default method 'all'(app.all()) will be used.
app.api('/posts/new', 'Posts.create', 'post');

this.send([code, ]response[, msg])

• default function for all controllers
• will format the 'response' data before res.send(), and will call res.send() automatically
• support ‘JSON' and 'XML' format, see Format below

Samples:

this.send('All done.'); // default code '200', default message see `Default HTTP Status` below
this.send(404, 'Nothing!');
this.send(500, 'Errors', 'Wrong URL！')
