Refreshing the page causes ERR_STREAM_WRITE_AFTER_END error

[G-Rath]

When refreshing the page with hmr enabled (and connected via websocket to the serve server), an exception is logged to the webpack console.

This doesn't actually stop anything from working.

• Webpack Version: v4.26.1
• Operating System (or Browser): Windows 10, Chrome 71.0.3578.80
• Node Version: v10.14.1
• webpack-plugin-dev Version: v0.1.2

How Do We Reproduce?

Expected Behavior

No errors in webpack console when refreshing page.

Actual Behavior

Error is logged:

I tested locally, even forcing a refresh (ctrl + shift + R) and i did not get an error... i'll see if i can create a windows box to test those types of problems.

@G-Rath I couldn't reproduce on my end, but that may very well be a windows-only issue.

Open up node_modules/webpack-plugin-serve/lib/routes.js and insert the following at line 83 (just before the for:

        socket.on('error', (...args) => {
          console.log('socket error', ...args)
        });

If that doesn't trap the error, try lib/ws.js and insert the following after line 15:

  socketServer.on('error', (...args) => {
    console.log('server error', ...args);
  });

Either of those might trap the error and prevent the output you're seeing.

(Of course, you can also use an inspector if you'd like to go that route.)

@G-Rath I think we've narrowed this problem down to a regression in Node 10.14.x. Try downgrading to 10.13.x and I'd bet you no longer see this error (that was the behavior we observed). I've reported this to the Node folks in the mean time.

[shellscape]

Confirmed. The node maintainers have identified this as a regression that snuck in. The solution is to use 10.0.0 - 10.13.0 until that gets fixed. Given that this is confirmed an upstream problem that's affecting more than this module, I'm gonna close it.

Cheers for reporting this originally, you helped a great many people by pointing out the problem 🍻

[G-Rath]

@shellscape could you link to the relevant material on the node side of things, so we can watch the issue?

[shellscape]

Yeah for sure nodejs/node#24958

Is 10.15 compatible? This was fixed nodejs/node#24958 (comment)
