WARNING: This is a simple server for use in testing or debugging Angular applications locally. It hasn't been reviewed for security issues.

Binding this server to an open connection can result in compromising your application or computer. Using a different host than the one passed to the "--host" flag might result in
websocket connection issues. You might need to use "--disableHostCheck" if that's the case.
WARNING: Running a server with --disable-host-check is a security risk. See https://medium.com/webpack/webpack-dev-server-middleware-security-issues-1489d950874a for more information.
