Conflicting values for 'process.env.NODE_ENV' ("'development'" !== "\"development\"")

[dangbert]

Current Behavior

NODE_ENV problem:

Initializing a new nx repo (with rspack) using npx create-nx-workspace@latest nxwarningdemo --preset=@nx/rspack --package-manager=yarn leads to a warning in the browser console upon running yarn start

dev server port configuration problem

Additionally, this may be a separate issue but the port the dev server runs on is unclear:

$ yarn start
yarn run v1.22.22
$ npx nx serve

> nx run nxwarningdemo:serve

NX  Server ready at http://localhost:4200

In reality localhost:4200 seems to be unused, wherease the dev server is actually running on localhost:8080

the output and port the dev server is running on doesn't change, the rspack dev-server port setting is not respected.

the output then becomes consistent with the same port listed on both lines and actually runs on the desired port (9999 in this case)

yarn run v1.22.22

Expected Behavior

no warning related to 'process.env.NODE_ENV

why does this bother me? Because on another repo, this warning is very disruptive to starting the dev server as it shows up in a pop-up immediately on page load:

also the config.devServer.port field in rspack.config.js should be respected, and port 4200 shouldn't be listed in the yarn start output (I think, this is unclear to me at least why that port is listed).

GitHub Repo

https://github.com/dangbert/nxwarningdemo

Steps to Reproduce

git clone [email protected]:dangbert/nxwarningdemo.git && cd nxwarningdemo/
yarn && yarn start

then visit localhost:8080 and check the browser console logs

Alternatively you can npx create-nx-workspace@latest nxwarningdemo --preset=@nx/rspack --package-manager=yarn instead of cloning my repo (which was created on Sept 22, 204 using the above command)

Additional Information

I will make a separate issue for the port configuration problem if desired, let me know

[samtsai]

Port issue seems to be the same as: nrwl/nx-labs#422

Once #27969 gets merged, I'll open a PR for it in this main nx repo.

[samtsai]

PRs are up!

[dangbert]

Much thanks @samtsai 🙏
