• Backend
  • Golang, Chi Framework
  • JWT for authentication
  • Rate limiting for registration endpoint
  • Payload validation using validate package
  • Cursor Pagination for Users and Transactions endpoints (using uuids and created_at values)
  • SQLC for getting the data, dbmate for managing migrations.
  • If you want to preview the backend endpoints, just copy gomarvin.json content in the editor (Settings -> Import Tab)
• Frontend
  • Vue 3 + Vite + Tailwind.
  • Registration and Login views
    • Field validation errors are returned from the database
    • Custom Login error messages if the user does not exist or the password is incorrect
  • Home view is guarded by authentication check. If the user has an invalid token, that route is not accessible.
• Other
  • Deno and Faker used for seeding the database (using the generated gomarvin client
  • Backend code baseline and frontend fetch functions generated with gomarvin.

DISCLAIMER

A lot of parts are rough around the edges and can be improved to avoid code duplication.

• JWT Auth flow in the frontend is lacking
  • access_token expiration is 15mins, no flow for re-authentication
• DB tables can be improved
• There are endpoints which don't execute any queries.
• Frontend is as minimal as possible
  • No loading states while fetching the data

Setup

• Use the db dump to create the db schemas and rows.
• Edit /backend/.env if needed

# run backend
cd backend
go mod tidy
go mod download
go run main.go

# run frontend
cd frontend
npm i
npm run dev

Other

# seeder (using deno with faker)
deno run --allow-net ./seeder.ts

# dump database info for test_db
sudo pg_dump -U postgres test_db > ./dump.sql
