I'm trying to customise the dev-server port, which I understand is possible thanks to PR #279, but I'm getting this in the browser console when I run nwb serve-react-app --port 3333:

It keeps logging stuff continuously. Am I missing something? Here is a text version (for search engines) of the output a bit further down the logs:

I'm using:

• Node.js 6.9.3
• Yarn 0.24.6
• nwb 0.17.0

v0.17.0 switched to Webpack Dev Server for nwb serve... comands - it looks like its client doesn't like the configuration we pass it when customising the host or port. Fix coming soon.

Fixed in v0.17.1 - thanks for reporting this!
