pause

What is pause?

The 'pause' npm package is designed to temporarily halt the execution of code. It is commonly used in scenarios where a delay is required before proceeding with the next part of the code. This can be particularly useful in asynchronous programming, testing, or creating time-based functionality.

What are pause's main functionalities?

Pausing execution for a set duration

This feature allows the user to pause the execution of code for a specified duration. In the provided code sample, the execution is paused for 2000 milliseconds (2 seconds) before printing 'End after 2 seconds'.

const pause = require('pause');

async function run() {
  console.log('Start');
  await pause(2000); // Pause for 2000 milliseconds
  console.log('End after 2 seconds');
}

run();

Other packages similar to pause

sleep

The 'sleep' package offers functionality similar to 'pause' by blocking the event loop to delay code execution for a specified time. Unlike 'pause', which is typically used in asynchronous code, 'sleep' can be used in both synchronous and asynchronous contexts, making it more versatile but potentially more disruptive to performance if not used carefully.

timeout

The 'timeout' package provides a way to delay the execution of code, similar to 'pause'. However, it is specifically designed to work with promises and async/await patterns, making it a good choice for modern asynchronous JavaScript applications. It offers a cleaner API for handling timeouts in promise chains compared to traditional methods.

pause

Pause a stream's data events

Installation

$ npm install pause

API

var pause = require('pause')

handle = pause(stream)

Pause the data events on a stream and return a handle to resume or end the stream.

handle.end()

Dispose of the handle. This does not end the stream, but it simply discards the event collection, making handle.resume() a no-op.

handle.resume()

Resume the stream by re-emitting all the data events in the same order, followed by an end event, if that was emitting during the pause.
