PIMS-400 Install TypeORM

[TaylorFries]

🎯 Summary

PIMS-400:

Adding the foundation for TypeORM to be used in express-api

Changes include:

• creating app-data-source.ts - used to create connection to database
• creating typeorm folder - used to hold all entities and migrations
• initializing connection in server.ts
• adding settings to typescript config file

To test:

• have docker containers for PIMS running
• stop api container
• navigate to PIMS/express-api
• run "npm run dev"
  • output should be similar to:

{"level":"info","message":"Server started on port 5000.","timestamp":"2023-12-18 08:27:02.221 AM"}
{"level":"info","message":"query: SELECT * FROM current_schema()","timestamp":"2023-12-18 08:27:02.244 AM"}
{"level":"info","message":"query: SELECT version();","timestamp":"2023-12-18 08:27:02.256 AM"}
{"level":"info","message":"query: START TRANSACTION","timestamp":"2023-12-18 08:27:02.260 AM"}
{"level":"info","message":"query: SELECT * FROM \"information_schema\".\"tables\" WHERE \"table_schema\" = 'public' AND \"table_name\" = 'typeorm_metadata'","timestamp":"2023-12-18 08:27:02.262 AM"}
{"level":"info","message":"query: COMMIT","timestamp":"2023-12-18 08:27:02.279 AM"}
{"level":"info","message":"Database connection has been initialized","timestamp":"2023-12-18 08:27:02.280 AM"}

To be consistent, does this file work as appDataSource? Camel case vs kebab case.
I realize that heath-router exists, but that should have been healthRouter probably too.

What does true argument do? I can't find documentation on this.

[TaylorFries]

I was trying to find the link again but couldn't - there are cases (in stackoverflow) where not passing in 'true' means that the custom logger never initializes and then throws an error when it is used.

Works well. Happy to see the custom logger.
Made a small change so the message always prints. It looked like it was only printing the type before.

Contents have changed. Will re-review when ready.

Ran in local with npm run dev and in container. Database connects successfully. Approved again.
