# Improve Node.js Architecture and Security

Node.js projects often adopt frameworks and patterns without considering runtime, deployment, or growth. This skill guides context-aware architecture, security, validation, and testing decisions.

## Capabilities

- Compares Hono, Fastify, Express, NestJS, and full-stack API options against deployment and team needs.
- Explains layered controller, service, and repository responsibilities for maintainable Node.js applications.
- Selects asynchronous patterns based on ordering, failure tolerance, timeouts, and event-loop impact.
- Defines validation boundaries, HTTP error semantics, and secure error-response practices.
- Provides security, testing, runtime, module-system, and implementation decision checklists.

## Use Cases

- Plan a New API: Select a framework, runtime, module system, and architecture from workload and deployment requirements.
- Review a Growing Service: Assess layer boundaries, error handling, validation, async behavior, security controls, and test priorities.
- Define Team Standards: Create practical Node.js guidance for architecture, security, testing, and event-loop safety.

## Prompt Templates

### Choose a Framework

```
Compare Node.js frameworks for my project. Ask about deployment, traffic, team experience, TypeScript needs, and legacy constraints before recommending one.
```

### Design the Architecture

```
Design a Node.js architecture for [project]. Define controller, service, and repository responsibilities. Explain where validation and error handling belong.
```

### Review Async and Security Risks

```
Review my Node.js design for event-loop blocking, unsafe async patterns, missing validation, secret handling, authorization, rate limiting, and dependency risks.
```

### Create an Implementation Decision Record

```
Produce a decision record for [system]. Compare frameworks and runtimes, justify architecture boundaries, define failure handling, and prioritize security and tests.
```

## Limitations

- Provides principles and recommendations, not a complete application implementation.
- Does not benchmark frameworks or runtimes against a specific workload.
- Requires project requirements and deployment constraints for precise recommendations.
- References 2025-era tooling, so users should verify current runtime and library support.

## Best Practices

- Provide deployment target, traffic profile, team experience, and growth expectations before requesting a recommendation.
- Validate recommendations against current Node.js and library documentation before implementation.
- Combine architecture guidance with benchmarks, threat modeling, tests, and production observability.

## Anti Patterns

- Selecting a framework only from popularity or benchmark headlines.
- Applying layered architecture to a small script without a clear maintenance benefit.
- Treating general security guidance as proof that a specific implementation is secure.

## Security Audit

- Audited at: 2026-08-04T16:11:31.459\+00:00
- Summary: All 30 static findings are false positives caused by Markdown fences, inline code formatting, defensive filesystem guidance, HTTP status documentation, and headings. The skill contains only instructional prose and no prompt injection, executable scripts, automatic commands, or filesystem actions.
