set-immediate-shim

What is set-immediate-shim?

The set-immediate-shim package provides a cross-environment implementation of `setImmediate`, a method for scheduling tasks to be executed after the current event loop tick. This is particularly useful in environments where `setImmediate` is not natively supported, such as in certain browsers or older versions of Node.js. The package ensures that developers can use `setImmediate` functionality consistently across different platforms.

What are set-immediate-shim's main functionalities?

Scheduling tasks

This feature allows you to schedule tasks to be executed after the current event loop tick. It's useful for deferring execution without resorting to `setTimeout(fn, 0)`, which can have different behaviors across environments.

require('set-immediate-shim');

setImmediate(() => {
  console.log('This runs after the current event loop tick.');
});

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.
