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.
