js-transform-plugin
An ast plugin for transforming js/ts/jsx/tsx files from commonJS to ESmodule. Here for the examples.
Usage
-
npm install -D js-transform-plugin
-
Add this script to package.json
{ "scripts": { "transform": "js-transform" } } -
npm run transform [absolute path]
- The default value of [absolute path] is process.cwd().
- The configuration of ignored files has not been supported. To avoid transforming node_modules dir, you can provide param, like, the absolute path of src dir. Or easier, just delete node_modules dir.
- Then js/ts/jsx/tsx files in [absolute path] will be transformed from commonJS to ESmodule recursively.

module.exports = abc;
module.exports = new Abc();
module.exports = fun(a, b);
module.exports = function(){};
module.exports = () => {};
