@babel/plugin-proposal-dynamic-import

What is @babel/plugin-proposal-dynamic-import?

The @babel/plugin-proposal-dynamic-import package allows Babel to parse and transform the dynamic import() syntax, enabling code splitting and lazy loading of modules at runtime. This is a stage 4 proposal in ECMAScript and is part of the official language specification.

What are @babel/plugin-proposal-dynamic-import's main functionalities?

Dynamic Import Syntax Transformation

Transforms the dynamic import() syntax so that it can be used in environments that do not support it natively. This allows for code splitting and loading modules on demand.

import('path/to/module').then(module => {
  // Use module.default or named exports here
});

Other packages similar to @babel/plugin-proposal-dynamic-import

@loadable/component

A higher-level library for React that provides a React component-centric way to dynamically load components. It uses dynamic imports under the hood and offers a more integrated experience with React, including server-side rendering support.

react-loadable

Another library for React that makes it easy to dynamically load components with a higher-order component. It provides a similar functionality to @loadable/component but was more popular before @loadable/component came around.

webpack

While not a direct alternative, webpack is a module bundler that supports code splitting out of the box using dynamic imports. It provides more comprehensive build-time support for splitting code and optimizing bundles.

systemjs

A dynamic module loader that can load ES modules, CommonJS, and AMD modules in the browser. It provides a polyfill for the dynamic import() syntax and can be used as a low-level alternative to Babel's transformation.
