backend-api-development
Build and optimize Node.js, Express, and Python backend services. USE THIS for API design, server setup, middleware, authentication, database connection, error handling, and microservices. Include when user mentions backend, API endpoints, server setup, database queries, authentication, or building REST/GraphQL APIs.
npx skills add majiayu000/claude-skill-registry --skill backend-api-development --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Backend & API Development Skill Build production-grade backend services with best practices in mind. ## Your Backend Stack ### Node.js/Express - **Framework**: Express.js - **Runtime**: Node.js 18+ - **Language**: JavaScript/TypeScript - **Database**: PostgreSQL, MongoDB, or SQLite (context-dependent) - **Authentication**: JWT or session-based ### Python - **Web Framework**: Flask or FastAPI - **Runtime**: Python 3.9+ - **Async Support**: asyncio/aiohttp - **Database**: Same as Node stack ## Key Responsibilities ### API Design ```javascript // RESTful conventions GET /api/resource // List all GET /api/resource/:id // Get one POST /api/resource // Create PUT /api/resource/:id // Update DELETE /api/resource/:id // Delete ``` ### Error Handling & Responses ```javascript // Consistent response format { status: 'success' | 'error', data: {}, // For successful responses error: { // For errors code: 'ERROR_CODE', message: 'Human readable', details: {} }, timestamp: ISO8601 } ``` ### Middleware Pattern ```javascript // Standard Express middleware order: 1. Body parser 2. CORS / Security headers 3. Request logging 4. Authentication 5. Route handlers 6. Error handling (last) ``` ### Databa

What does the backend-api-development skill do?
Build and optimize Node.js, Express, and Python backend services. USE THIS for API design, server setup, middleware, authentication, database connection, error handling, and microservices. Include when user mentions backend, API endpoints, server setup, database queries, authentication, or building REST/GraphQL APIs.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill backend-api-development --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
