Hi can we merge this ASAP @evilebottnawi @hiroppy 🙏

[hiroppy]

Thank you for fixing this issue. LGTM

Sorry but I don't have webpack-dev-server's read-write right of npm so we wait for @evilebottnawi

[alexander-akait]

Need tests, also please avoid fs.readFileSync and path.resolve, we already do this in Server
