TypeScript | Node.js | Express.js API Bootstrap (template)

This repository is intended to serve as a starting point if you want to bootstrap a quick API project in TypeScript.

⚠️ It is meant for simple use cases where you don't need the extra complexity, just a barebones, simple Node.js API. This has its shortcomings:

• No proper DI framework/container/tool
• No Clean Architecture structuring (I strongly suggest a DDD approach)
  • Coupling of infrastructure and application layers unless you separate them yourself

If these issues don't matter for your intended use, or you know how to fix them, this will be a fast way to have an API running. If you're looking for a more scalable strategy, check my TS DDD template or if you're looking for a simple, plain Node.js app look at my TypeScript Node.js Template

Features

• Pure DI. If you prefer using containers, check out:
  • tsyringe
  • typescript-ioc
  • TypeDI
  • NestJS
  • InversifyJS
  • Awilix
  • If you prefer mocking dependencies (no DI) use proxyquire
• TypeScript
  • Find other tsconfig.json options here
  • tsx when running TS files directly
• pnpm for package management
• Biome for formatting and linting.
• Node Test Runner for testing.
  • Accompanied by Supertest to test API calls.
• GitHub Action workflows set up to run tests and formatting+linting on push
