Requirements

• Use TypeScript throughout the backend
• Use NestJS as the framework
• Use a SQL database via a modern ORM (e.g. Prisma, Drizzle, or TypeORM)
• Use pnpm or yarn for dependency management and scripts
• Document the REST API with OpenAPI / Swagger
• It should be open sourced on your github repo

Extras

• Implement DDD Pattern
• Implement Unit Testing
• Provide a docker-compose setup for the API and database
• Implement load testing with k6

Notes

• Feel free to add some structure or plugins

Frontend Test Case

• Create features based on the RESTful API that has been created using NestJS.
• It should use React
• It should use TypeScript
• It should use Ant Design for styling (you can customize the UI if you are interesting with UI/UX)
• Use pnpm or yarn for dependency management and scripts
• It should be open sourced on your github repo

Extras

• Test your components with jest
• It should use Clean Architecture as design pattern
• Use a monorepo (e.g. pnpm/yarn workspaces) to host the API and web app together (plus point)
