Confirmed this doesn't work via the bare Node API atm, you could use

webpack.config.js

const config = {
  //...
  devServer: {
    open: true
  }
};

in the meantime

/cc @hiroppy after refactor bin it should be easy to fix, can you help with this too, you are do amazing job :+1: Just need move event handler in Server instead bin, same problem for bonjour

[hiroppy]

open(https://github.com/webpack/webpack-dev-server/blob/master/bin/utils.js#L91-L95) seems to be called only by webpack-dev-server.js(https://github.com/webpack/webpack-dev-server/blob/master/bin/webpack-dev-server.js) (as status).
package.json calls "lib/Server.js".

@hiroppy yep, we should move all what starting with https://github.com/webpack/webpack-dev-server/blob/master/bin/webpack-dev-server.js#L172 in lib/Server, it is fix open/ when you use Node API, i think it is architecture bug and will be great fix it.
