Framework selection depends on your deployment environment, team experience, and scale. This skill provides a decision-tree approach covering Express, Fastify, Hono, NestJS, and Next.js API routes to match your specific project context and constraints.

Best practices include centralized error handling, non-blocking I/O, and proper async pattern management. This skill covers explicit guidelines for these areas, applicable across Node.js 22+, Bun, and Deno runtimes with TypeScript support.

Layered architecture enforces separation of concerns for both testability and scalability. This skill guides you through architecture principles, runtime decisions, and baseline quality practices to apply from day one of your project.

Secure Node.js applications require input validation, centralized error handling, and secure secrets handling. This skill outlines these security best practices alongside testing strategies and performance considerations for modern runtimes.

This skill applies across the full spectrum—from small scripts to enterprise APIs. It covers framework selection, runtime decisions, and architecture principles that scale to your project's complexity and team size.

Runtime selection depends on your project requirements and team priorities. This skill provides decision guidance for modern runtimes including Node.js 22+, Bun, and Deno, with native TypeScript support across all options.
