Node REST API

Full CRUD REST API using Node.js with no framework

This is a full REST API from scratch using simple vanilla node.js to demonstrate the fundamental principles of a REST API:

Usage

I have deployed a live server running the REST API: http://195.201.88.30 at Port 81
You can easily query the routes provided below using POSTMAN.

# Routes
GET      http://195.201.88.30:81/api/products
POST     http://195.201.88.30:81/api/products
GET      http://195.201.88.30:81/api/products/:id
PUT      http://195.201.88.30:81/api/products/:id
DELETE   http://195.201.88.30:81/api/products/:id

HowTo built

1. • create json file with products to imitate a database where we can request and send data

     data/products.json

   • initialize a package.json

     npm init -y

   • to monitor the server.js

     npm i -D nodemon

   • to create Id's automaticaly we need a tool uuid

     npm i uuid

   • create starting scripts

     "start": "node server.js", "dev": "nodemon server.js"

   • create server.js as an entry-point with
     • http-module (comes with node.js) as method to start the http-server

       const http = require('http')

     • import products to GET the data from the server

       const products = require('./data/products')

2. • to create different routes use models and controllers = mvc-method (model-view-controller|view like react won't be needed as it's an pure api to test)
     • to interact with the model (get,put,delete data etc.)

       controllers/productController.js

     • to handle the data

       models/productModel.js

3. • connect server.js to the mvc:

     const { getProducts, getProduct, createProduct } = require('./controllers/productController')

   • connect utils.js to productModel to write data to file

     const fs = require('fs')

4. • create the routes in the productController:
     • GET allProducts = getProducts()
     • GET a single Product = getProduct()
     • POST data to the json = createProduct()
     • PUT update data by id = updateProduct()
     • DELETE deletes data by id = deleteProduct()

5. Check all routes and functions with postman

   • Pics of all request are in the POSTMAN Folder
