Compression in webpack-dev-server

See original GitHub issue

Is there a reason that compress key is not set in WebpackDevServer config? I tried it on my machine and it made reloads faster and bandwidth usage smaller without any apparent problems.

I can send a PR if that’s okay.

FYI, an unexpected consequence of webpack dev server compression is that Server Sent Events over proxy would be buffered, instead of proxied instantaneously.

The issue goes away in production mode, or if I set the webpack dev server compress flag to be false in dev mode.

I bet there are some tricks that would allow compression on without affecting Server Sent Events, but I haven’t figured it out yet.

This has most certainly caused problems with Server-Sent-Events. I’m using this in my project, and have determined that the gzip compression is causing the event connection to close. I’m struggling to find a way to unset this - however, it’s not clear to me why this change was made, since in a development environment it’s a low-impact issue to have non-compressed files served. The trade-off of making SSE unusable doesn’t seem to have been a good call.

Thanks.
