Backend Runtime Expert Guide

This skill provides the standards for building scalable, enterprise-grade backend services across multiple runtimes.

🦅 NestJS (Node.js)

• Modular Design: Use Modules to group related functionality. Follow the Dependency Injection pattern.
• Controllers & Services: Keep controllers thin. Put business logic in services.
• Pipes & Guards: Use Pipes for validation/transformation and Guards for authentication/authorization.

🦕 Deno

• Security: Leverage Deno's permission system (e.g., --allow-net, --allow-read).
• Standard Library: Prefer the Deno standard library for basic utilities.
• Deploy: Use Deno Deploy for edge computing and low-latency execution.

📄 Payload CMS

• Collections & Globals: Define clear schemas for content. Use hooks for side effects.
• Access Control: Implement granular permissions per collection and field.
• Customization: Extend the admin UI using custom React components.
