pr05 Typescript Migration #13: Migrate the User Model (& API Key schema)

[clairep94]

Migration of the user model to ts

• made some assumptions/work arounds to solve type errors
• This is a best effor, I will attempt the user controller next -- I expect that that attempt may result in tweaks to this file afterwards
  • I actually originally attempted to migrate the entire user system (controller, model, routes) but this was too difficult to do without previous PRs being finalised and merged. Please see here for that attempt
• Added a test for the user model before migrating, so I could ensure nothing breaks
• All tests pass & all typechecks pass

Changes:

• Move apikey schema to its own file
• Add test for user model
• Extract types from user and api key
  • Note: my original approach was to use mongoose inferSchemaType and other infers but this was honestly really hard to debug and it was easier to explicity define what we expect from the types and feed it to the mongoose scheme definition, and attach the extra Document methods
• Migrate apiKey and user to ts & to named export

I have verified that this pull request:

• has no linting errors (npm run lint)
• has no test errors (npm run test)
• is from a uniquely-named feature branch and is up to date with the develop branch.
• is descriptively named and links to an issue number, i.e. Fixes #123
• meets the standards outlined in the accessibility guidelines

we don't need usePushEach anymore? is it set to that by default? just wanted to make sure it didn't slip through the cracks!
