set-immediate-shim

set-immediate-shim

Simple setImmediate ponyfill

The shim uses the native setImmediate when available (Node.js), falls back to MessageChannel for better performance in environments that support it (modern browsers, Deno), and uses setTimeout with zero delay as a last resort.

Install

npm install set-immediate-shim

Usage

import setImmediateShim from 'set-immediate-shim';

setImmediateShim(() => {
	console.log('2');
});

console.log('1');

//=> 1
//=> 2

Similar packages

Other packages similar to set-immediate-shim

core-js

core-js is a modular standard library for JavaScript, which includes polyfills for ECMAScript up to 2021. It offers a `setImmediate` polyfill among many others, providing a broader scope of functionality compared to set-immediate-shim. While set-immediate-shim focuses solely on `setImmediate`, core-js covers a wide range of ECMAScript features, making it a more comprehensive solution for cross-environment compatibility.

process

The process package is a browserify implementation of the Node.js 'process' module, which includes a nextTick method that can be used similarly to `setImmediate` for queuing tasks after the current event loop tick. While `setImmediate` and `process.nextTick` have slightly different use cases and behaviors, the process package provides a similar functionality for environments where `setImmediate` is not available. It's more focused on mimicking Node.js environment capabilities in non-Node.js environments.
