I'm a beginner in Node (and generally all back-end web development), and I have started to write a RESTful API in Node. There are a few things I'm trying to get my head around.
My application uses Express and Mongoose, and I am using the express-resource module to easily create my CRUD routes for the API resources. But there are a couple of things I am unhappy about, and think I could do better.
The first is Mongoose. If I want to write tests for my API, I have no way of stubbing Mongoose to force it to in memory data. All of the tutorials out there seem to point to Mongoose, however, and I'm really not sure what I should be using.
Secondly, my resource seems to have a lot of boilerplate code. Is this really the best way to create a RESTful API in Node.js? Are there other modules that will help me to create my CRUD routes? I believe there are ways you can create CRUD routes right from your schema, without anymore code, but I'm really not sure how.
I have seen projects out there such as Tower.js and CompoundJS (formally RailwayJS) that seem to be these comprehensive solutions that solve much more than my issues here. Perhaps I should be using them, but I really only want the Node.js application to be an API and nothing more. I am dealing with the front-end independently of the API.
To provide some context, here is my current situation. Currently, I have a model defined in Mongoose:
var mongoose = require('mongoose')
, Schema = mongoose.Schema
, Link
var LinkSchema = new Schema({
uri: String,
meta: {
title: String,
desc: String
},
shares: [{
uid: Schema.Types.ObjectId,
date: Date,
message: String
}]
})
Link = module.exports = mongoose.model('Link')
Next, I define the controllers for the CRUD routes:
var mongoose = require('mongoose')
, _ = require('underscore')
, Link = mongoose.model('Link')
exports.load = function (req, id, fn) {
Link.findById(req.params.link, function (err, link) {
if (err) {
return res.send(err)
}
fn(null, link)
})
}
exports.index = function (req, res) {
var filterByUser = req.query.user ? { 'shares.uid': req.query.user } : {}
Link.find(filterByUser, function (err, links) {
if (err) {
return res.send(err)
}
res.send(links)
})
}
exports.create = function (req, res) {
var link = new Link(req.body)
link.save(function (err) {
if (err) {
// TODO: send 404
return res.send(err)
}
res.send(link)
})
}
exports.show = function (req, res) {
res.send(req.link)
}
exports.update = function (req, res) {
req.link = _(req.link).extend(req.body)
req.link.save(function (err, link) {
if (err) {
return res.send(err)
}
res.send(link)
})
}
exports.patch = exports.update
exports.destroy = function (req, res) {
req.link.remove(function (err) {
if (err) {
return res.send(err)
}
res.send()
})
}
Finally, I use the express-resource module to map these controllers to the necessary CRUD routes on top of the Express app.
app.resource('api/links', require('../resources/links'))

Answer 1

You should look into restify
If you want to use express, you can also check out this project that I made -- called node-restful.
This library seems to be much more mature and have more features though: https://github.com/jspears/mers

Answer 2

Strongloop Loopback seeems to be another good alternative for generating Node/MongoDB APIs. It can also generate mocha tests too.

Answer 3

Take a look at Hapi its a configuration-centric framework for building web applications and APIs its used as restful service.
Other options are sails.js and actionhero

Answer 4

Strapi is a new (2015) framework.
The admin interface on their website allows you to create an API and specify relationships between models. (As can be seen in their introduction video.)
However it is designed to run on the Koa server, not on Express.

Answer 5

I recommend Baucis + Express. Thousands of users, model-driven design based on Mongoose, very flexible, spec-compliant, HATEOAS/Level 3 ready. Fits all my needs perfectly. But then, I'm the author :) https://github.com/wprl/baucis

Answer 6

Check this out:
With Feathers you can build prototypes in minutes and production ready real-time backends and REST APIs in days. Seriously.

Answer 7

Here is the issues about the frameworks nowadays.
When you come here from google searching "best", "fastest" framework blah, blah, people will drop a line says "Hey, you should try this sails.js, feathers, Derby etc..."
Ok The question is:
- Are you just for fun with those frameworks - if yes, you can easily get a list of frameworks and then start to benchmark them whatsoever.
I am assuming most of people are "I want to build a product, build a site can make money in the future, or at least it will become popular";
Ok, all you search keywords and attentions here is wrong, try to search "production ready", "enterprise ready", "case study" those keywords then, or maybe go to indeed.com and search node.js, further dig out what node.js framework most companies using, the answer maybe just simply say "express".
if so, From node.js stack, The frameworks will pretty much be narrowed down a few of them: Hapi, Strongloop, or even not popular one Mojito from Yahoo
For Those frameworks at least you can tell - "They are really production or enterprise ready" - cos' they have been using form Walmart, from Yahoo, from other big giants from some time, some even for couple of years.
Can this explain why Ruby on rails and Django still dominate the full stack framework markets? even you see lots of "cool" frameworks keeping on coming to the market, Meteor, Sails.js, Go's Revel, Java's Play Spark whatever you can name - It doesn't mean these frameworks worse than the two, just mean they need time to win the market.
Another problems lots of the current frameworks are a kind of all-in-one, clone of "Ror"; From the end user's prospect, They just need a thing to help them get things done, need productive, need something to work from the begin to the end, like Ruby on Rails, like MacOS, like windows, like anything itself which has been tested by the time, has been daily used by people.

Answer 8

I've been using Express to build my RESTful APIs on Node.js and with the addition of Router in Express 4, it's even easier to structure it. It's detailed here http://www.codekitchen.ca/guide-to-structuring-and-building-a-restful-api-using-express-4/

Answer 9

Try https://hivepod.io/ and generate your example in a full MEAN stack. Hivepod builds on top of BaucisJS + ExpressJS + MongoDB + AngularJS.
Disclaimer: I work building Hivepod.

Answer 10

Have a look into this link
This project is build using the same project archutecture which is followed by ASP.Net WebApi 2.0. That means it will be having controllers, authentication mechanism etc. to start with. All you need to do is create your own controllers.

Answer 11

I'm surprised no-one mentioned Nodal.
From the website:
Nodal is a web server for Node.js, optimized for building API services quickly and efficiently.
Boasting its own opinionated, explicit, idiomatic and highly-extensible framework, Nodal takes care of all of the hard decisions for you and your team. This allows you to focus on creating an effective product in a short timespan while minimizing technical debt
It's actively maintained, has 3800+ stars on Github (at the time of writing), has a command-line tool built-in to generate boilerplate code, and overall gets the job done quickly.

Answer 12

This is a sample to perform CRUD operations in a library system
var schema=require('../dbSchema');
var bookmodel=schema.model('book');
exports.getBooks = function (req,res) {
bookmodel.find().exec().then((data)=>{
res.send(data)
}).catch((err)=>{
console.log(err);
});
};
exports.getBook = function (req,res) {
var bkName=req.params.Author;
bookmodel.find({Name:bkName}).exec().then((data)=>{
res.send(data)
}).catch((err)=>{
console.log(err);
});
};
exports.getAutBooks = function (req,res) {
bookmodel.find({},'Author').then((data)=>{
res.send(data);
}).catch((err)=>{
console.log(err);
});
};
exports.deleteBooks=function(req,res){
var bkName=req.params.name;
bookmodel.remove({Name:bkName}).exec().then((data)=>{
res.status(200);
console.log(bkName);
}).catch((err)=>{
console.log(err);
});
};
exports.addBooks=function(req,res){
var newBook=new bookmodel({
Name:req.body.Name,
ISBN:req.body.ISBN,
Author:req.body.Author,
Price:req.body.Price,
Year:req.body.Year,
Publisher:req.body.Publisher
});
newBook.save().then(()=>{
res.status(201);
}).catch((err)=>{
console.log(err);
});
};

Answer 13

I am a big fan of express and I've been using it to build RESTful APIs on Node.js which are easier to build. However, when our application started growing, we ended in a situation where express structure did not scale well and with more code splitting around, it was harder for us to maintain.
I am from C#/Java background where SOLID principles are heavily used. Frameworks like Java Spring / C# WebAPI are proven to create enterprise level applications.
I wanted to have a framework where I can reuse my existing C#/Java skills (reuse I mean MVC architecture, OOPS, SOLID, DI, Mocks ... yeah, strong typing). Unfortunately, I did not find a framework which meets my requirements (It should have less learning curve, minimalist codebase size, completely express compatible).
What do I mean by completely express compatible? Whatever express does, I must be able to do it even If I use a framework on top of it, when I have looked into Strongloop Loopback it was pretty good to use but It had a lot of documentation to go through and the frameworks are coupled, not really what I was looking for.
So I have created Dinoloop powered by Typescript (has interfaces, classes, abstract classes and strong oops). The package is pretty stable now.
With Dinoloop you can build enterprise level applications in a scalable architecture.
It uses Dependency Injection framework but you can configure any DI frameworks available in typescript. Dinoloop enables typescript to use as a Nodejs REST framework that helped me to maintain common typescript codebase for both angular and node projects.
So, Dinoloop is a perfect fit for typescript lovers and angular developers.
