Write a stream in node js

Writing to a Stream
Create a js file named main.js with the following code −

var fs = require(“fs”);
var data = ‘Simply Easy Learning’;

// Create a writable stream
var writerStream = fs.createWriteStream(‘output.txt’);

// Write the data to stream with encoding to be utf8
writerStream.write(data,’UTF8′);

// Mark the end of file
writerStream.end();

// Handle stream events –> finish, and error
writerStream.on(‘finish’, function() {
console.log(“Write completed.”);
});

writerStream.on(‘error’, function(err){
console.log(err.stack);
});

console.log(“Program Ended”);

output
Program Ended
Write completed.
