[Question] Compatibility with Webpack APIs and migrating an old custom plugin

[ahmedelgabri]

I'm working on migrating a large and old application from Webpack to Rspack, and we currently have a blocker with one of our custom plugins. So wanted to check what our alternatives are.

The plugin in a nutshell only allows some paths to be imported inside some specific entry files, anywhere in these files graph.

new MyPlugin({
   allowedPaths: [
      'node_modules',
      'path_to_a'
   ].map((p) => path.join(process.cwd(), p)))
})

First problem: compilation.asyncEntrypoints is not supported https://rspack.dev/api/javascript-api/compilation

compiler.hooks.emit.tapAsync('MyPlugin', (compilation, callback) => {
	compilation.asyncEntrypoints.forEach(entrypoint => {
		entrypoint.chunks.forEach(chunk => {

Second problem: instanceof checks for NormalModule, ConcatenatedModule and WorkerDependency

I noticed that there is NormalModule Class but nothing for the rest.

const ConcatenatedModuleClass = require('webpack/lib/optimize/ConcatenatedModule')
const NormalModuleClass = require('webpack/lib/NormalModule')
const WorkerDependency = require('webpack/lib/dependencies/WorkerDependency')

There are probably more issues, but right we can't even run the plugin. So I was wondering what are our options here?
