Webpack 5 node builder warnings DEP_WEBPACK_WATCH_WITHOUT_CALLBACK, DEP_WEBPACK_MODULE_ERRORS

[Nightbr]

Hey,

thanks for this awesome project and to be ultra up-to-date with state-of-the-art technologies!!

I have some warnings with Webpack 5 in nestjs application.

Current Behavior

$ nx serve api                

> nx run api:serve 

>  NX  Using webpack 5. Reason: detected version 5 in node_modules/webpack/package.json

(node:33773) [DEP_WEBPACK_WATCH_WITHOUT_CALLBACK] DeprecationWarning: A 'callback' argument needs to be provided to the 'webpack(options, callback)' function when the 'watch' option is set. There is no way to handle the 'watch' option without a callback.

Expected Behavior

We should not have warnings:

(node:33773) [DEP_WEBPACK_WATCH_WITHOUT_CALLBACK] DeprecationWarning: A 'callback' argument needs to be provided to the 'webpack(options, callback)' function when the 'watch' option is set. There is no way to handle the 'watch' option without a callback.
(node:33773) [DEP_WEBPACK_MODULE_ERRORS] DeprecationWarning: Module.errors was removed (use getErrors instead)

Steps to Reproduce

npx create-nx-workspace --preset=nest
npx : 48 installé(s) en 3.283s
✔ Workspace name (e.g., org name)     · NestTest
✔ Application name                    · api
✔ Use Nx Cloud? (It's free and doesn't require registration.) · No
cd nest-test/
npx nx g @nrwl/node:webpack5
nx serve api

I also have this issue with in Linux.

Possible solution

For DEP_WEBPACK_WATCH_WITHOUT_CALLBACK it seems it is throw because we call webpack with --watch option with the config watch: true in the config. -> webpack/webpack-cli#1918

For DEP_WEBPACK_MODULE_ERRORS, it seems it is from ts-loader. I tried to upgraded to the latest ts-loader v9.2.5 but I still have the warning -> TypeStrong/ts-loader#1194

If you have any question or need any debug logs, feel free to ask ;)

Cheers
