Documenting Your Tech Stack in README
Learn how to present your project's tech stack effectively. Covers technology badges, architecture diagrams, version requirements, and dependency rationale.
Detailed Explanation
Presenting Your Tech Stack
The Tech Stack section helps potential contributors understand the technologies involved before they dive into the code. It also helps users evaluate whether your project fits their ecosystem.
Simple List Format
For most projects, a bulleted list works well:
## Tech Stack
- **Runtime**: Node.js 18+
- **Framework**: Express.js 4
- **Language**: TypeScript 5
- **Database**: PostgreSQL 15
- **ORM**: Prisma 5
- **Cache**: Redis 7
- **Testing**: Vitest + Supertest
- **CI/CD**: GitHub Actions
- **Deployment**: Docker + AWS ECS
Table Format with Descriptions
For larger projects, a table adds context:
| Technology | Version | Purpose |
|---|---|---|
| Next.js | 14 | React framework with SSR |
| TypeScript | 5.3 | Type-safe JavaScript |
| Tailwind CSS | 3.4 | Utility-first CSS |
| Prisma | 5.8 | Database ORM and migrations |
| PostgreSQL | 15 | Primary data store |
| Redis | 7 | Session storage and caching |
| Vitest | 1.2 | Unit and integration tests |
| Playwright | 1.41 | End-to-end tests |
Badge-Based Tech Stack
Some projects use technology badges for visual appeal:
Architecture Overview
For complex projects, a brief architecture note helps:
### Architecture
The application follows a layered architecture:
\`\`\`
Client (React) --> API Routes (Next.js) --> Services --> Prisma --> PostgreSQL
--> Redis (cache)
\`\`\`
Why These Technologies?
Optionally explain key technology choices:
- Prisma over TypeORM: Better TypeScript integration and migration management
- Vitest over Jest: Faster execution with Vite-native ESM support
- Tailwind over CSS Modules: Consistent design tokens and faster development
This helps contributors understand the project philosophy and prevents "why not use X" issues.
Use Case
Adding a clear tech stack section to a project README that helps contributors understand the technology choices and set up their development environment correctly.
