Summary

The backporting of `require(esm)` to Node.js 20 marks a significant advancement towards resolving the longstanding divide between CommonJS (CJS) and ECMAScript Modules (ESM) in the Node.js ecosystem, as Node.js 18 approaches its end-of-life in April 2025. Joyee Cheung's efforts have enabled library maintainers to confidently transition to ESM-only packages, reducing complexity and eliminating the need for CJS builds. This change, first introduced with Node.js 22.12.0, allows developers to leverage ESM with greater ease while maintaining compatibility with Node.js 20. The process involved extensive refactoring and patching to ensure stability, and it is celebrated by the developer community as a milestone in simplifying module management and advancing the adoption of ESM across the JavaScript landscape.
