A zero-dependency ECMAScript module loader for Node.js that enables ESM syntax (import/export, import.meta, dynamic import) in Node 6+ without Babel or bundling. It provides full CommonJS interoperability and can be enabled via require hook or the -r esm flag.

Use cases

• use ES module import/export syntax in older Node.js versions
• run ESM files with node -r esm without a build step
• mix CommonJS and ES modules in the same project
• enable ESM support in a package without transpiling with Babel
• load ES modules in the Node REPL
• pass test262-compliant module behavior in Node

When to choose

• you're stuck on an older Node.js version without native ESM support
• you need ESM syntax with full CommonJS interoperability and no build tooling
• you want a zero-dependency, production-ready module loader

When to avoid

• you're on modern Node.js with native ESM support (use built-in modules)
• you need actively developed tooling with ongoing updates
• you rely on .mjs files with advanced esm options
