node.js: readline : pause event

The 'pause' event is emitted when one of the following occur:

a.   The input stream is paused.

b.   The input stream is not paused and receives the 'SIGCONT' event.

The listener function is called without passing any arguments.

Example

rl.on('pause', () => {

  console.log('Readline paused.');

});

Find the below working application.

HelloWorld.js

/* Import readline module */
var readline = require('readline');

/*
 * create a new readline.Interface instance that reads data from standard input
 * and write data to standard output
 */
var rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});

// Adding close and pause events
/* Add a callback function on readline.Interface instance close event */
rl.on('close', function(){
 console.log("Close event received");
});

/* Add a callback function on readline.Interface instance pause event */
rl.on('pause', () => {
  console.log('Readline paused.');
});

/* Ask a question to the user and print the received answer */
rl.question("Enter something ", function(data){
 console.log("You entered %s", data);
 rl.close()
});

Output

Enter something Hello World

You entered Hello World

Readline paused.
