Node.js : Reading a file line by line

Create a file as app.js (or whatever name you want) and paste below code -

app.js

const readline = require('readline');
const fs = require('fs');
var file = 'path.to.file';
var rl = readline.createInterface({
 input: fs.createReadStream(file),
 output: process.stdout,
 terminal: false
});
rl.on('line', function (line) {
 console.log(line) // print the content of the line on each linebreak
});

path.to.file will be path of your file and once modified this line you can run 'node app.js' and you will get the file reading as line by line.

With all that being said, I highly recommend you keep learning!
