Architecture

• user Clean Architecture / Vertical Slice Architecture
• Carter/MediatR separate dependencies between Api Layer vs Business Logic
• Endpoint contains all the logic right from url, to business code to persistance
• • easy to test / mock the flow

Considerations

• Code generated is using random characters for now
• can pre-generate/cache codes for better performance

Libraries

• Minimal API: goes better with REPR pattern / VSA architecture
• IDistributedCache: used in-memory cache for now, but can easily wrap around RedisCache
• EF Core - for database persistance
• Carter - to scan & register all minimal-api endpoints
• MediatR - to execute client requests/commands
• FluentValidation - to fluent validation request DTO
• FluentAssetion - better testing library
• FakeItEasy - to create fake object/responses
• Serilog - for logging
• Swagger - to test the endpoints

Open Items

• Can use repository to easily mock database dependency
• • not done here, as persistance was not a requirement
• FastEndpoints - provides all the goodies, but lot more stuff with it
• Docker containers: not done, as it was not a requirement

Running the code

• to run dotnet watch run --project ./Bitly/Bitly.csproj
• to test dotnet test ./Bitly.sln
