nodejs-best-practices Skill (sickn33) for Claude Code

Makes Claude choose Node.js frameworks, patterns and security practices from your context instead of defaulting to one stack.

Stars: 49K; on GitHub
Updated: Nov 2026; last repo commit

The skill teaches decision-making, not code to copy. It tells Claude to ask about your deployment target, cold-start needs and team experience, then pick a framework: Hono for edge and serverless, Fastify for performance, NestJS for structured teams, Express for legacy and ecosystem, or Next.js and tRPC for full-stack.

It also covers module systems, a controller-service-repository layout, error handling, async patterns, validation libraries, a security checklist and test strategy. SKILL.md says its framework comparisons are qualitative and not benchmark evidence.

Good for

Developers starting a new Node.js service or API
Teams comparing Hono, Fastify, Express and NestJS
Reviewers checking a Node.js app against a security and testing checklist

What it includes

A decision tree from build target to framework
Hono for edge or serverless, Fastify for high-performance APIs, NestJS for enterprise teams, Express for legacy, Next.js API routes or tRPC for full-stack, with four questions to ask first.
Try: “I need a Node API on Cloudflare Workers. Which framework and why?”
Framework selection
Native TypeScript, ESM versus CommonJS, Node versus Bun versus Deno
Says to check the installed Node release before relying on type stripping, to use ESM for new projects and CommonJS for older code.
Runtime considerations
Controller, service and repository layers
Explains the layers and when to skip them, for example small scripts and prototypes.
Architecture
Central handler, custom errors and a status code table
Clients get a status, code and friendly message with no internal details, and logs get the stack and request context.
Error handling
async/await, Promise.all, allSettled and race
Notes that async helps I/O-bound work, not CPU-bound work, and that a timeout race does not cancel the underlying work.
Async patterns
Validate at the boundaries with Zod, Valibot, ArkType or Yup
Lists where to validate and when each library fits.
Validation
Ten items from input validation to dependency audits
Includes parameterized queries, bcrypt or argon2, JWT verification, rate limiting, Helmet, HTTPS, CORS and secrets handling.
Security checklist
Unit, integration and end-to-end with node:test, Vitest, Supertest, Playwright
Test priorities and the built-in test runner in Node 22 and later.
Testing
Questions to answer before implementing
Includes whether you asked about stack preference and a limitations note: examples are not benchmark evidence and not a substitute for review.

Questions

What does the nodejs-best-practices skill do?

It guides Claude through Node.js decisions: which framework, which module system, how to layer the code, and how to handle errors, async work, validation, security and tests. It stresses choosing by context.

How do I install it?

Use the install box above. It is a single SKILL.md in the sickn33/agentic-awesome-skills repo, so the skills CLI install is all you need.

Does it write code for me?

It mainly gives principles, decision trees and checklists, and tells Claude to ask you about your stack when unclear. Claude still writes the code in your project as usual.

Which framework does it recommend?

It depends on your target. Hono for edge and serverless, Fastify for performance, NestJS for enterprise teams, Express for legacy code and the largest ecosystem. SKILL.md says the comparisons are qualitative and to benchmark your own workload.

What does the risk: critical label mean?

The frontmatter has risk: critical, source: community and a date_added value. SKILL.md does not explain the risk field, and the file bundles no scripts. Read the file yourself if you need to know what the label is based on.

Is it safe?

The file bundles no scripts and only holds instructions. It is a community skill, so read SKILL.md before you rely on its advice, which says it is not a substitute for environment-specific validation or expert review.
