Nodejs Patterns
WHAT: Production-ready Node.js backend patterns - Express/Fastify setup, layered architecture, middleware, error handling, validation, database integration, authentication, and caching. WHEN: User is building REST APIs, setting up Node.js servers, implementing authentication, integrating databases, adding validation/caching, or structuring backend applications. KEYWORDS: nodejs, node, express, fastify, typescript, api, rest, middleware, authentication, jwt, validation, zod, postgres, mongodb, redis, caching, rate limiting, error handling
Why use this skill?
Build scalable Node.js backends with our proven pattern guide. Learn Express and Fastify best practices, layered architecture, secure validation, and error handling.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/wpank/nodejs-patternsWhat This Skill Does
The Node.js Patterns skill provides a robust architectural blueprint for building scalable, maintainable, and secure backend applications. It serves as a pedagogical and scaffolding tool that enforces industry best practices for Express and Fastify frameworks. By emphasizing a strictly layered architecture—separating concerns into controllers, services, and repositories—this skill helps developers avoid the 'spaghetti code' trap often found in large-scale JavaScript projects. Beyond architecture, it provides boilerplate for essential security headers, schema-based input validation via Zod, connection management for databases like PostgreSQL or MongoDB, and centralized error handling routines. It is designed to act as a source of truth for TypeScript-based backend development, ensuring that type safety is maintained across the entire stack.
Installation
To integrate this skill into your development workflow, use the OpenClaw CLI:
clawhub install openclaw/skills/skills/wpank/nodejs-patterns
Use Cases
This skill is ideal for teams starting a new microservice, developers migrating legacy callbacks to modern async/await patterns, or engineers looking to standardize their REST API boilerplate. It is particularly useful for:
- Building secure authentication flows using JWT.
- Setting up high-performance APIs with Fastify and JSON schema validation.
- Implementing complex business logic that requires clear separation from HTTP transport layers.
- Optimizing database interaction through structured repository patterns.
Example Prompts
- "OpenClaw, setup a new Express project structure using the Node.js Patterns layered architecture and add middleware for rate limiting."
- "I need a repository pattern implementation for a PostgreSQL user database in TypeScript using the Node.js Patterns guidelines."
- "Show me how to implement a global error handling middleware for my Fastify API that hides stack traces in production."
Tips & Limitations
To maximize effectiveness, strictly adhere to the 'NEVER' section of the guide: do not hardcode secrets, and always validate input at the edges. Note that while this skill provides the structure, it does not replace the need for your own unit testing strategies like Jest or Vitest. Ensure you have the latest TypeScript versions installed to support advanced type features utilized in these patterns. Finally, consider that this skill is strictly for backend patterns; it does not provide frontend integration or UI-related patterns.
