Running free code camp tutorials offline

Continuing the discussion from Free code camp honesty policy:

Hi, i’m running into some issues during this process:

  1. There’s a lot of errors on the terminal, for example:

  1. Its been on “Building development bundle” for over 45 mins, is that normal

There is only one error - for the most part, you can ignore the warnings and suggestions.

This is saying the server cannot connect to the database. If you have started the database, then you may need to double check you have not changed any default start locations.

Depends on the hardware you are running it on, but 45min is excessive.


My suggestions:

  1. If you are trying to set fCC up locally, follow the official Contributors Docs. These are up-to-date, and are the recommended way to do so
  2. Develop your client and server in separate terminals:
    Terminal A
npm run develop:server

Terminal B

npm run develop:client

This will help you identify when errors are coming from the client or the server.

Hope this helps
