babel-plugin-transform-modules-commonjs lazy import transform

[airhorns]

babel and @swc/core both support a really handy option for large projects: automatic lazy import transformation. If you depend on hundreds of modules, in development it is a lot faster to only require what is actually touched, instead of executing every require/import statement. Then, when a module is actually used the first time, say in a request handler, you can require it them, drastically improving boot/reload performance locally.

We make heavy use of this in my project via https://www.npmjs.com/package/wds, and we were looking at porting wds over to use oxc but noticed this one missing feature.

PS: oxc is a really amazing project so far, thanks so much for all your hard work on it!
