Move on to ESM-only
[[toc]] Three years ago, I wrote a post about shipping ESM & CJS in a single package, advocating for dual CJS/ESM formats to ease user migration and trying to make the best of both worlds. Back then, I didn't fully agree with aggressively shipping ESM-only, as I considered the ecosystem wasn't ready, especially since the push was mostly from low-level libraries. Over time, as tools and the ecosyst
Node.js — Node.js v22.10.0 (Current)
Or if the package is only meant to be run on Node.js and wants to fallback to CJS on older versions that don't have require(esm): { "type": "module", "exports": { // On new version of Node.js, both require() and import get the ESM version "module-sync": "./index.js", // On older version of Node.js, where "module-sync" and require(esm) are // not supported, use the CJS version to avoid dual-package

process.getBuiltinModule(id) は TypeScript を ESM 化させるか？
こんにちは teppeis です。普段は開発本部長をやってますが、ブログフェスに駆り出されました！ 本日は Node v22.3.0 に続いて v20.16.0 にもバックポートされた process.getBuiltinModule(id) について解説します。 問題: 同期的な条件付き require を ESM 化できない Node v22 にて、フラグ付きで CJS (CommonJS Modules) から ESM を require できるようになりました。いわゆる require(esm) です。これにより、今までは互換性の懸念で ESM 化を足踏みしていた著名ライブラリも ESM 化を試みる動きが出てきました。 TypeScript もその一つで、TypeScript チームは TypeScript 自体を ESM 化しようと試みました。しかしながら、今回の主題である条件付

require(esm) in Node.js
Recently I landed experimental support for require()-ing synchronous ES modules in Node.js, a feature that has been long overdue. In the pull request, I commented with my understanding about why it did not happen sooner before this pull request in 2024. This post expands on that comment a bit more. The opinions in this post are my own and reflect my perception of the ESM development in Node.js as
