This is a tutorial to create our own COVID tracker using the following tools,

  • Node.js
  • NPM
  • ejs
  • Express

First do an npm init using following command,

npm init

Then install express and ejs using npm with the following command,

npm i express ejs

Then install corona-info npm package using the following command,

npm i corona-info

Install nodemon using the following command,

npm i nodemon

After installing all the above dependencies, your package.json should look like this,

Then add the following code to index.js file (create a file named index.js in your folder where you have package.json and node_modules folder)

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")

})

For the front end code, create a file index.ejs under views/index.ejs as shown below,
