In this blog, I will be explaining how to create a login API view with Node js and JWT. So let’s get started.

1. Initial Setup

I this section, I am just summarizing what we did in the previous blog.

Initially we created a server and connected it to the MongoDB database with the mongoose instance. Then we created four folders named Models, Middleware, Controller, Routes.

index.js

const express = require('express')
const bodyparser = require('body-parser');
const mongoose = require('mongoose')
const router = require('./Routes/auth.route')
var app = express()
//Routes
app.use(bodyparser.json())
app.get('/', function(req,res){
res.send('Hello world')
})
app.use('/account/api',router)
//MongoDb connection
mongoose.connect('mongodb://localhost/test', {useNewUrlParser: true});
mongoose.connection.once('open',function(){
  console.log('Database connected Successfully');
}).on('error',function(err){
  console.log('Error', err);
})
//Server
app.listen('8000',function(req,res){
  console.log('Serve is up and running at the port 8000')
})

After creating the server, we created a route file named auth.route to handle all the authentication requests.

Routes/auth.route.js

const router = require('express').Router()
const signup = require('../Controller/auth.controller')
const {validateUser} = require('../Middleware/validation');

router.post('/signup',validateUser,signup.signup)
module.exports = router

Then we created a user Schema with attributes name, email, password.

Models/user.model.js

const mongoose = require('mongoose')

const userSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true,
    max: 200,
  },
  email: {
    type: String,
    required: true,
    unique: true,
  },
  password: {
    type: String,
    required: true,
    min: 5
  },
 },{timestamps: true}
)
module.exports = mongoose.model('User',userSchema)
