Make Clean Code changes for backend app

[MarkWiltberger]

Make the Clean Code changes for frontend app that stem from the feedback in the Customer List App Project Issue:

• https://github.com/MarkWiltberger/customer-list-app/issues/11

Specifically:

• [ ] Remove any code that’s not specific to your application or that is produced by a CLI.
• [ ] Remove all comments except those completely necessary. Instead, explain the code with the code itself.
• [ ] Follow the “There’s a type for that” rule, meaning you shouldn’t use “any” anywhere in the application.
• [ ] Remove all console logging.

---

For "Remove any code...":

• [x] Remove app.service.ts which issues a getHello() service from the root endpoint.
• [x] Remove references to app.service.ts from app.module.ts
• [ ] Remove app.controller.ts which calls getHello() from app.service.ts
  • [ ] No, instead, put a redirect in app.controller.ts
• [x] Remove references to app.service.ts from app.module.tx
• [ ] Remove app.controller.spec.ts because there will be no more controller to test.
  • [ ] No, instead, modify app.controller.spec.ts to test for redirect.
• [ ] Modify app.e2e-spec.ts for references to test GET root for 'Hello World' response.

---

• [ ] Manually test all changes to code.

• -Created a branch for the changes for the issue: make-clean-code-changes-for-backend-app-0001

  • Added redirect for root GET endpoint to customer and committed. Note that this still results in a 404 not found error.

  • [ ] I will need to modify app.controller.spec.ts file when I test the changes.

  • I deleted app.service.ts and modified app.module.ts and committed.
