the errors about lol-pick-ban-ui

[Laraakaa]

Hey, you get exactly one error and it's telling you:
Error: listen EADDRINUSE: address already in use :::8999

This error tells you that the application tries to open a socket on port 8999, but fails to do so because port 8999 is already occupied. Please check that no other application is listening on that port - e.g. another instance of the application.

Btw in the message you write that you are starting the frontend, but this is actually the backend. The frontend is located in https://github.com/RCVolus/lol-pick-ban-ui/tree/master/layouts/layout-volu-europe

To build the frontend, you need to clone / check out the git repository (as you probably already did since you started the backend).

Then, head in the folder layouts/layout-volu-europe and spin up a command line.

Then execute the following two commands to first install all dependencies and start it afterwards:

npm install
npm start

The second command will open up a web page, but you will get an error. This is because no backend is provided. To launch it using a local backend (meaning you let the backend and the frontend run on the same machine) you need to open the url http://localhost:3000/?backend=ws://localhost:8999
