Expense tracker

How do I use it?

The API:

Navigate to ExpenseTracker.Api and execute

dotnet run

If ports 5000 and 5001 are free, you can query it at localhost:5001/expenses

The Frontend:

In another terminal, navigate to ExpenseTracker.Api/expense-tracker and execute

npm install

and

npm start

If port 4200 is free, you can navigate to localhost:4200 in your browser and see this:

If I had more time...

I would

• Test more! Not much in terms of logic for the API, but more for the frontend app.
• Docker-compose, it's rather awkward to set up the app now. I'd create a container each for the frontend app, the api and the db like I do in my other project here: https://github.com/fhammerl/polls
• Configuration: I have a lot of hardcoded configs I'm not proud of, would have to get rid of them anyway to dockerize the system
• Performance:
  • Think about performance more when I have some use cases
• Refactorings:
  • Probably a multi layer architecture for the API (Api, Core, Services and Data)
  • Add some sort of linting / auto formatter
  • Not a fan of raw injecting the DbContext in particular, a service layer would be nice
• Actually use ExpenseType (food, drink, other)
• Validation server side - at least for stuff like currency -> currencyEnum
• Support my App Insights logging with some events perhaps?

Technology choices

Visual Studio Code + Remote Development / Dev Containers

With VS Code Remote Development, you can use a Docker container as a full-featured development environment. VS Code is going to work as if it was running locally on the Linux container. Other tools offer similar solutions of course (mounting the workspace, hot-reload), but I find the extreme approach of hooking the entire "IDE" into a container quite inspiring.

To open the dev container:

• Open the folder in VS Code
• Reopen in container (popup in bottom right of the window)
• Hit F5 to start the API
• Note that the container is not setup to run the frontend app (yet!)

Sqlite

I wanted a db that you could plug and play without actually having to install an external DB or have a container running your DB server, Sqlite was perfect for this. With more time, I'd probably use docker-compose to include my devcontainer and a standalone db instance in a network.

What I'd do differently

• Less time on the frontend
• Not forget about adding the user_id to the
