[Bug]: warning failed to get stats with lazyCompilation in dev mode

[bigbossx]

System Info

Details

when i use rsbuild v1.0.19 with lazyCompilation mode.

the browser will show hmr connect and reload, and wait compilation done

But in v1.1.4 the browser will remain on the white page unless you refresh the page manually. it's a bad dev experience

Reproduce link

No response

Reproduce Steps

export default defineConfig({
  dev: {
    progressBar: true,
    lazyCompilation: true
  },
})

rsbuild dev

Can you provide a minimal repro ? If so I can fix this in maybe several days

@JSerFeng here.

finally I find that I was using an https domain name proxy for development instead of localhost.

• if i use localhost, everything work find

• but for avoid cors limited I dev with Whistle
  

you can also reproduce in here

I think maybe eventSource or http-server broken in lazyCompilation mode when we use domain proxy

please let me know if it still need more info

[JSerFeng]

lazy-compilation has no idea of dev-server proxy, I'm thinking we should implement lazy compilation by a normal middleware instead of eventSource, I'll fix this later, thanks for investigating

[bigbossx]

@JSerFeng Thanks for your quick reply.
btw, it only happen when i use 1.1.x. everything worked when i use 1.0.x

[JSerFeng]

That's wired, lazy compilation almost has nothing changes since 1.0

[bigbossx]

That's weird.

you can compare branches main(v1.0.19) and bug-lazy(v1.1.4)

[JSerFeng]

Since you are using system proxy, can you try to get DevServer instance ? If so, you can pass it to lazyCompilation configuration like:

{
  lazyCompilation: {
    backEnd: { server: () => server /*your server instance*/ }
  }  
}

This might solve it

@JSerFeng

I think I misled you. I made a wrong judgment. the problem is not that I am using a domain name proxy, but there will be problems with IP access.

you can try reproduce it

when i visit with localhost

when i visit with ip
