Error Cannot find module '../webpack-runtime.js' when using esbuild-loader

[rizrmd]

Hi,

I tried to improve blitzjs live-reload loading time by installing esbuild-loader in my project. As per https://github.com/privatenumber/esbuild-loader/issues/62,

Good news is live-reload time are noticeably improved, pages are rendered fine, but then this error happened. the error pops when I tried accessing api route with db access in it.

this is the error message :

24:25:16.425.000         ERROR  Error while processing the request

Any suggestion ?

Tried removing webpack 5 in my package.json does not do any difference.

Hmm, I don't know what would be the fix. __db.js is the compiled version of db/index.ts and is configured here: https://github.com/blitz-js/blitz/blob/canary/packages/server/src/with-blitz.ts#L22

This is an interesting topic for me. When I tried to reproduce it, I got the following error in my environment.

...
ready - started server on http://localhost:3000
error - ./pages/_app.tsx
Error: [BABEL] <local path>/.blitz/caches/dev/pages/_app.tsx: Cannot find module '@babel/plugin-syntax-typescript'
...

This seems to be a problem that depends heavily on Next. Do I need to rewrite the loader and some plugins for esbuild to handle __db.js issues and these? https://github.com/vercel/next.js/blob/canary/packages/next/build/webpack/loaders/next-babel-loader.js

@AkifumiSato possibly? I'm not sure, this is beyond my experience!
