Not reloading anymore when React components have changed in DEV

[binarykitchen]

With my current setup, rsbuild isn't hot-reloading anymore when I've modified a React component locally in DEV mode.

It was working fine a while ago. I guess a recent upgrade broke it.

Attached is my complete rsbuild config (using Rsdoctor)
rsbuild_config.json

And these are my rsbuild related dependencies:

    "@rsbuild/core": "1.3.6",
    "@rsbuild/plugin-node-polyfill": "1.3.0",
    "@rsbuild/plugin-pug": "1.0.2",
    "@rsbuild/plugin-react": "1.2.0",
    "@rsbuild/plugin-stylus": "1.1.1",
    "@rsbuild/plugin-svgr": "1.1.1",
    "@rsdoctor/rspack-plugin": "1.0.1",

    "rsbuild-plugin-google-analytics": "1.0.3",
    "rsbuild-plugin-open-graph": "1.0.2",

Can you spot what's wrong? Happy to provide more data if neeed.

Thanks!

Are you using react-scan? #5006

[binarykitchen]

I don't see react-scan in the package-lock.json, so probably not.

I've read https://rsbuild.dev/guide/faq/hmr and can tell step (1) is happening, [HMR] connected. is being logged.
But step (2) hot-update.(js|json) requests aren't happening at all. What could be the cause why no hot-update requests are happening?

How can I debug and investigate HMR best?

[chenjiahan]

You can check the Web Socket request and view the messages and compare them with the normal messages.

[binarykitchen]

Thanks. Nothing gets logged. Something is wrong.

It was working fine a few months ago 🤷

[binarykitchen]

It's a big app. A reproduction repo is quite lot of work. Sigh ...

[binarykitchen]

I've emailed you an email separately.

Then, regarding Web Socket requests, nothing gets logged on the WS tab:

But JS files and JSON are being updated.

@chenjiahan I've found the cause. It was a wrong port number, ooops :)
