ESM-CJS Interop Test

View on GitHub

This project is forked from sokra/interop-test with the following changes:

  • Many test cases / exporting modules removed
  • TypeScript file extensions tested
  • package.json "type": "module" tested
  • Every test case is tested against every importing file variant
  • Every runtime result is diffed against every other
  • Added meta-analysis to answer high-level questions
  • Added Bun, Parcel, Vite

Meta-analysis

Synthesizing default exports for CJS modules

In Node, a default import of a CommonJS module always links to the module.exports object. In other words, a CJS module imported from ESM looks like [Module: null prototype] { default: (module.exports) }. This is sometimes called “synthesizing” a default export. Traditionally, bundlers and ESM-to-CJS transpilers have instead linked default imports to the module.exports.default property when there is also an exports.__esModule property (indicating that the module was transpiled from ESM). In other words, they selectively disable default export synthesis, whereas Node always enables it. This creates an inconsistency between how some imports behave in Node and how they behave in bundlers. Consequently, esbuild and Webpack adopt Node’s behavior and always synthesize default exports in files that Node would recognize as ESM—that is, files with an .mjs extension or "type": "module" in package.json. (So... they selectively disable their selective disabling of default export synthesis?)

This practice is Probably A Good Idea, but if it’s applied based on file extensions, it must be done for the equivalent TypeScript file extensions as well in order for TypeScript to reason about the behavior. My priorities are ordered as follows:

  1. Consistency between JS and TS variants
  2. Consistency between all bundlers (lol)
  3. Default export synthesis for CJS modules imported from .mjs, .mts, and "type": "module"-scoped .js and .ts files for compatibility with Node
  4. No default export synthesis for CJS modules with __esModule when imported from files that are not .mjs, .mts, or "type": "module"-scoped .js and .ts files

The following table summarizes data that can be found in the default-export-esModule.js table, and grades each bundler’s behavior against these priorities.
