Building NPM packages for CommonJS with ESM dependencies

1. esm-commonjs-support

   1 1 0 4.2 TypeScript

   

   If you're impatient, you can go straight to the code with this example implementation.

2. SurveyJS

3. esbuild

   2 356 38,910 9.2 Go

   An extremely fast bundler for the web

   

   You have to use a bundler such as esbuild which will compile your project and bundle all of it's dependencies along with it so they aren't imported. This bypasses the ESM/CommonJS incompatibility issue.

4. token.js

   3 3 236 8.8 TypeScript

   Integrate 200+ LLMs with one TypeScript SDK using OpenAI's format.

   

   While preparing to release my new project Token.js over the weekend, I ran into a quite frustrating problem. I wanted my package to support CommonJS in addition to ESM, but I had pure ESM dependencies. The pure ESM crusaders out there might be quite unhappy about me saying it, but if you are building an NPM package and want it to be widely used you still need to support CommonJS in 2024.
