lemon-mart-server database doesn't seem to initialize

[virshu]

docker compose --up build is supposed to work automagically - so I am not sure where to troubleshoot.. I see that web-app started successfully, and I can open a website on localhost:8080. But something is wrong with lemondb - it runs commands, and then it shuts down and keeps restarting - but fails again. And I assume because of that server shows "Exited (1)" in docker desktop.

If there is some things to look and/or tweak, I am happy to do. Ideally, I would prefer to understand what is going on on the server side (I have many years of server-side development; although mostly not in NodeJS). But if it works as black box - OK; as long as it works.

For what it's worth I have NodeJS 22, and installation flashed a warning that it may not be compatible.
Thank you - loved the Angular portion of the book; in part because I was able to figure out the errors in the sample code

@virshu I apologize for the delayed response.

I've tested against Node 22 and haven't seen an issue related there. However, I would recommend sticking to the LTS version of Node at all times, which is at 20 currently.

To troubleshoot this I'd recommend gradually bringing up the component parts:

1. First bring up the database with npm start:database -- if there's an issue at this step, then it's likely there's some sort of configuration issue with Docker, a missing file, or disk access permissions.
2. Next you can bring up npm start:backend and if successful it should report:

lemon-mart-server  | Connected to database!
lemon-mart-server  | Server listening on port 3000...
lemon-mart-server  | Initializing default user...
lemon-mart-server  | Create indexes...
lemon-mart-server  | Found existing user... deleting
lemon-mart-server  | Done.

If there's a failure here, please ensure that the server works by running it separately. If there are issues with the server, then there might be an authentication issue with MongoDB. In this case, please double check your environment variables and if you believe those are correct you can use the MongoDB Explorer tool by Studio 3T to manually log in to it.
3. Once you clear all the issues then docker compose --up build should work as expected.
