devServer.port is ignored in config

[kirill-konshin]

This issue is a: Bug report

On latest NWB if config exports the following the port is still 3000:

module.exports.devServer = {
    port: '8080'
};

Based on following docs it should work: https://github.com/insin/nwb/blob/master/docs/Configuration.md#dev-server-configuration and https://webpack.js.org/configuration/dev-server/#devserver

Is there any other way to configure port from JS?

Some of the devServer options are only used by webpack-dev-server's CLI, which nwb isn't using, so you currently you have to pass a --port option to the nwb serve command instead.

devServer config is available when nwb is starting the server, so we can can also add support for using devServer.port if it's configured.

Yes of course I am aware of —port CLI param, but it’s not always convenient. It would be great if config will be respected )

Wow that was fast! Thanks! When to expect NPM release?

[insin]

Should be later today, there are some dependency updates I want to include as well.

Found a weirdest bug on version 0.21.3.

When I run with exports.devServer.port = '8080' I get:

Something is already running on port 8080.
? Would you like to run the app on another port instead? (Y/n) 

Notice that port 8080 is in the message. I double checked http://localhost:8080 and $ lsof -i tcp:8080 — there's nothing running.

But when I do nwb serve-react-app --port 8080 everything just works even without changing the config :) how weird...
