Server trouble on OSX

[chris-rogers-anki]

I can run the app, however there does not seem to be a server running websockets on localhost:8080

App.tsx:252 WebSocket connection to 'ws://localhost:8080/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

I can run other servers and access them through localhost.

error message:

when i run "cd server && npm start" I get:

Error: Cannot find module '/Users/chris.rogers/workspace/posenet-for-installations/server/dist/index.js'

running "yarn build" fixed it.
