We've just published an experimental pre-release version 1.9.0-pr.431.1597 that adds CommonJS support to all npm packages in the Fedify ecosystem! 🧪

What's new

This experimental build addresses one of the most requested features—better compatibility with CommonJS-based Node.js applications, especially NestJS projects. The pre-release eliminates the need for Node.js's --experimental-require-module flag and resolves dual package hazard issues.

Note: While we now support CommonJS for legacy project compatibility, we still recommend using ESM or migrating to Deno for the best experience with Fedify.

Who should test this?

• NestJS developers using Fedify who need CommonJS compatibility
• Legacy CommonJS-based Node.js projects that had trouble integrating Fedify
• Anyone who previously needed experimental Node.js flags to use Fedify

How to test

Install the experimental pre-release version:

npm install @fedify/fedify@1.9.0-pr.431.1597
# or for specific integrations
npm install @fedify/nestjs@1.9.0-pr.431.1597

You should now be able to use standard require() syntax without any experimental flags.

What we're looking for

• Does CommonJS import work correctly in your legacy project?
• Are you able to remove the --experimental-require-module flag?
• Any issues or regressions compared to the current stable version?

Your feedback on this experimental build is invaluable for ensuring this major compatibility improvement works smoothly before the official 1.9.0 release!
