Let's install webpack and webpack-cli, we'll be using Webpack 5

webpack/webpack-cli repo issue: Error when run npm start: Class constructor ServeCommand cannot be invoked without 'new' #2272

Okay. The normal setup is that you use https://github.com/TypeStrong/ts-loader or https://github.com/TypeStrong/fork-ts-checker-webpack-plugin as part of your Webpack config. Those will run the TS compilation step as part of the Webpack processing sequence.

I work on a TypeScript project of similar size and complexity, and ours does not take even nearly that long to compile on save. Have you tried fork-ts-checker-webpack-plugin? We had compile times similar to yours until we started using it. Went from >60s to <1s builds in development. It's very simple to set up.

Yeah, I mean less loaders = less time. Did you try fork ts checker and compileOnly? https://github.com/TypeStrong/fork-ts-checker-webpack-plugin

That worker/memory limit is for the type checking only (rather than runtime memory), I believe this is done using https://github.com/TypeStrong/fork-ts-checker-webpack-plugin

There are many ways to integrate TypeScript with an existing Webpack configuration. If you use the babel-loader package to transpile JavaScript files, you can add the @babel/preset-typescript preset to generate JavaScript files and the Fork TS Checker Webpack Plugin package to run the TypeScript type checker so that the build fails if there are type errors.

esbuild-loader (secret sauce!) fork-ts-checker-webpack-plugin (helps us with typechecking) nodemon-webpack-plugin (We can also use webpack-dev-server)

I cloned github repo into a new dir, ran install with --frozen-lockfile and test-gui with --clean and got the same error. Looks like it's coming from fork-ts-checker-webpack-plugin and then found this among its reported issues: (https://github.com/TypeStrong/fork-ts-checker-webpack-plugin/issues/562).

You may want to check out this webpack plugin [1], though I'm not sure how much it could get you there.
