A JavaScript polyfill implementing the WhatWG ES module loader API with low-level hooks for building custom module loaders. It supports the System.register and System.registerDynamic formats for exact ES module loading semantics, including CommonJS interop.

Use cases

• load ES modules in browsers that lack native support
• build a custom ES module loader on a low-level loader API
• mix ES modules and CommonJS modules in one module graph
• run ES modules in Node with CommonJS interop
• polyfill the import and registry loader API

When to choose

• you need to support ES module loading in legacy environments without native module support
• you are building a custom module loader and need low-level loader hooks
• you need System.register format loading with exact ES module linking semantics

When to avoid

• your target environments natively support ES modules
• you need a maintained solution - the project has not released since 2018
• you want a modern bundler-based module workflow instead of a runtime loader
