    }
}

Should be fixed in master, I’ll do it from tomorrow and do new beta release

📝@alexander-akait I do not use beta-0 because i’m both hacking around and writing types, and I wanted to take into account latest api changes.

🔶 Instally from github directly just do not work (at least with yarn), because some files need a build step after cloning the repo (I get an error related to some ../../client module not being found) That’s part of the reason why I was asking this.

🟢In case it helps I ended-up cloning the repo, tweaking things around, building it, creating an npm tarball with npm pack, copying the archive in my project, then installing it via some {..., "webpack-dev-server": "file:./forks/webpack-dev-server-4.0.0.tgz", ...}. It was the best compromise I found to avoid polluting git history, and ensuring everyone on my team use the same version.
