Build Node.js Express Coronavirus COVID-19 Tracker Web App in Browser Using EJS & Javascript Full Project For Beginners

 

 

npm init -y

 

 

npm i express ejs

 

 

npm i corona-info

 

 

npm i nodemon

 

 

After installing all this libraries make an index.js file and copy paste the following code

 

 

index.js

 

 

const express = require('express')

const covid = require('corona-info'); 

const bodyParser = require('body-parser')

const app = express()

app.set('view engine',"ejs")

app.use(bodyParser.json())

app.use(bodyParser.urlencoded({extended:false}))

app.get('/',(req,res) => {
    res.render("index")
})

app.post('/getdata',(req,res) => {
  var country = req.body.country

  covid.findData({ country: country }).then(response => {
    console.log(response);

    res.json({
        data:response
    })
  });
})

app.listen(5000,() => {
    console.log("App is listening on port 5000")
})

 

 

 

And now make a views folder and inside it make an index.ejs file and copy paste the following code

 

 

views/index.ejs
