Writing Your First REST API

REST API

so this is the second part to my previous post 'Understanding REST api',in this part we'll make a small REST - API in node JS. so without further ado let's start making your first ever API

TOOLS

1. install node js (https://nodejs.org)
2. install vs code (editor)
3. install POSTMAN (for testing routes)

Steps

• create a folder
• initialize the folder with

npm init -y

• open the folder in vscode
• type ctrl+shift+` in your keyboard to open integrated terminal
• we'll be using expressjs for writing api
• so in terminal type npm install express uuid
• uuid will help us to create a RFC random id
• in package.json go to scripts and replace tests with "scripts":{ "start":"node app.js" }

LET'S start

create a file called app.js in your root folder
inside app.js write the following code

all of our routes are stores in folder called routes/routes.js
inside routes.js write the following code

how to check whether request working or not?
open the postman , if you want a get request ,select GET from a dropdown , and type endpoint in url section

in upcoming blogs , we'll cover how to deploy a complete rest api on heroku :)
