Thanks, there’s also https://github.com/nodejs/loaders-test/tree/main/coffeescript-loader which is more of the reference implementation (did you base yours off of this, or of the example in the Node docs?).

I need to work out how to handle ESM in general in the project before we can land this. Probably add an "exports" field, etc.

谢谢，还有https://github.com/nodejs/loaders-test/tree/main/coffeescript-loader更多的参考实现（你的基础是这个，还是节点文档中的示例？ ）。

我需要弄清楚如何在项目中处理 ESM，然后才能实现它。可能会添加一个"exports"字段等。

this can use with CommonJS , but coffeescript-loader can't

i write this base on nodejs documents , but there is error to use code in nodejs documents when use nodejs 18.7.0

i write a new version there
https://github.com/iuser-dev/nodejs-loader/blob/main/src/index.coffee

this version can both use import './xx.coffee' or import './xx'
