restex

restex

Simple and minimalist API wrapper based on top of Expressjs with support mongoose & sequelizejs

Note To: For now I support only mongoose, very soon I'll come with sequelizejs

Requirements

You need Node.js ^7.10.1 installed and you'll need MongoDB installed and running.

Initialize restex using mongodb database(mongoose) L

const express = require("express"),

  RestEx = require("restex");

  
let app = express()

//Restex connecting to mongodb using mongodb url

let restex = new RestEx(app, {
  database: {
     provider: "mongo",
     conn: {
        uri: "mongodb://localhost:27017/mydb"
     }
  },
  controllersPath: path.resolve(__dirname + "/controllers"),//optional
  modelsPath: path.resolve(__dirname + "/models"), //optional
  routesPath: path.resolve(__dirname + "/routes"),//optinonal
  middlewaresPath:path.resolve(__dirname+"/middleware.js") //optional
});

Initialize restex using existing mongoose connection instance

const express = require('express');
const mongoose = require('mongoose');
const RestEx = require("restex");

let app = express()
const mongoose = require('mongoose');
// Basic usage
mongoose.connect(connectionOptions);
const mongooseConnection = mongoose.connection;
// Advanced usage

const mongooseConnection = mongoose.createConnection(connectionOptions);

//Restex connecting to mongodb using mongodb url

let restex = new RestEx(app, {
   database: {
     provider: "mongo",
     mongoose:require('mongoose'),
     conn: {
        mongooseConnection:mongooseConnection
     }
    },
    controllersPath: path.resolve(__dirname + "/controllers"),
    modelsPath: path.resolve(__dirname + "/models"),
    routesPath: path.resolve(__dirname + "/routes"),
    middlewaresPath: path.resolve(__dirname + "/middleware.js")
});

Initialize restex using sequelize ORM database

const express = require("express");
const Sequelize = require('sequelize');
const RestEx = require("restex");
let app = express()
//connect to sqlite database, you also need to in

const sequelize = new Sequelize('sqlite::memory:');
//Restex connecting to mongodb using mongodb url

let restex = new RestEx(app, {
	database: {
		provider : "sequelize",
		Sequelize : Sequelize,
		conn: sequelize
    },
    controllersPath: path.resolve(__dirname + "/controllers"),//optional
    modelsPath: path.resolve(__dirname + "/models"), //optional
    routesPath: path.resolve(__dirname + "/routes"),//optinonal
    middlewaresPath:path.resolve(__dirname+"/middleware.js") //optional
});

controllersPath

path to controllers directory

default : controllers
@type {string}

modelsPath

path to models directory where you define mongoose schemas

default : models
@type {string}

routesPath

path to routes directory where you define routes for app

default : routes
@type {string}

middlewaresPath

path to middleware file

default : middleware.js
@type {string}

Follow the following file structurre for models,routes & controllers

models ()

1 Mongodb(mongoose)

//user.js

module.exports = function(mongoose) {

	let modelName = 'users';
	const Schema = mongoose.Schema;
	var userSchema = new Schema({
		name: String,
		email: { type: String, required: true, unique: true },
		password: { type: String, required: true },
		createdAt: { type: Date },
		updatedAt: Date
   });
	userSchema.pre("save", function(next) {
		if (this.isNew) {
			this.createdAt = new Date();
		} else {
			this.updatedAt = new Date();
		}
	})

	userSchema.statics = {
		collectionName:modelName // default file name >>user,
	}
	return userSchema
};

2 sequelize(Relational Database)

module.exports = function(sequelize,Sequelize){
    const modelName = 'user'
	const User = sequelize.define(modelName, {
		name: { type: Sequelize.STRING },
		email: { type: Sequelize.STRING }
	});
	User.statics = {
		collectionName:modelName // default file name >>user,
	}
	return User;
}

routes

//user.js

module.exports = function(router) {
  router.post("/authenticate", "user#authenticate");
};

Note: user#authenticate

user >> controller

authenticate >> handler defined in controller

Controllers

//users.js

const model_name = 'users'// make sure user schema exist in models dir
module.exports = function(restex){
	let Dao = restex.dao(model_name)
	let authenticate = function(req,res,next){
		//Using Promise then & catch
		Dao.get({email: req.body.email,password:req.body.password})
		.then(user=>{
			res.json(user)
		}).catch(err=>{
			return next(err)
		})

	 // Using async/await
	try{
		let user = Dao.get({email: req.body.email,password: req.body.password})

	}catch(e){
		return next(e)
	}
 }
	 return {
	 	authenticate
	 }

}

  

middleware

//middleware.js

module.exports = function(restex){

  const middleware1 = function(req,res,next){
	const auth = true;
	if(auth){
		return next()
	}
	next({status:401,message:'Unauthorized})
  }
  const middleware2 = function(req,res,next){
	/paste your middleware snippet
	next();
  }
  return {
	middleware1,
	middleware2
  }
}

And you can directly use middleware name in routes file

const customMiddleware = function(req,res,next){
	returen next()
}
router.get('/users','user#show',{middleware:['middleware1','middleware2',customMiddleware]}

Dao object consist of following predefined CURD methos

• Dao.get({email:email})).then(=>{}).catch(=>{})

• Dao.getAll({company:<company>},{page:1,limit:10})

• Dao.destroy({email:email}).then(=>{}).catch(=>{})

• Dao.update({email:email},{name:'Scott Tiger'}).then(=>{}).catch(=>{})

• Dao.add({email:'[e-mail]',name:'Scott Tiger'}

In some case if you need access mongoose Model directly.

const model_name = 'users'
module.exports = function(restex){
	let UserModel = restex.model(model_name)
	let authenticate = function(req , res,next){
		UserModel.findOne({email:req.body.email,password:req.body.password}).lean()
		.then(user=>{
			res.json(user)
		}).catch(err=>{
			return next(err)
		})
	}

 return {
	authenticate
 }
}

Automatic CRUD API creation

by default CRUD api will be created according to collectionName provided in mongoose Schema

userSchema.statics = {
	collectionName:'users'
}

GET /users

DELETE /users/:id

PUT /users/:id

GET /users/:id

POST /users

To add middleware option for CRUD api ,add routeOption while defining mongoose model

userSchema.statics = {
	collectionName:'users',
	routeOption:{
	  middleware:['middleware1','middleware2']
	 }
}
