Problems while running on windows (Unknown signal: SIGUSR2)

[GiladShoham]

Hi,
I have a problem when running on windows, this code:

if (__DEV__) {
      compiler.watch({}, reporter);

      compiler.plugin('done', () => {
        const { output } = serverConfig;
        startBackend = true;
        if (server) {
          server.kill('SIGUSR2');
        } else {
          runServer(path.join(output.path, output.filename));
        }
      });
    }

and specificlly this line:

server.kill('SIGUSR2');

Are failing due to error:
Unknown signal: SIGUSR2

Have you tried to run it on windows?
Do you have any idea how to solve this?

Thanks,
Gilad.

Yeah, it's weird. Webpack is using SIGUSR2 for hot code replacement on signal. SIGUSR2 seems to be not available on Windows.

The alternative is to comment out this line and change webpack/hot/signal.js entry point to webpack/hot/poll?1000. It should work on Windows.

Thanks for the help,
I have also found out that change SIGUSR2 to SIGINT make it work.
(But I still have problems with the hot reload on windows)

If you are sending SIGINT, I believe the Node.js process will be simply terminated and according to the logic of webpack.run.js it will be restarted immediately after termination. Though this might work for you - it is not hot reload, it is just restart of backend process on source code modification.
