Nestjs Patterns

affaan-m/ecc
2.1k installs240.8k stars
Summary

This is a solid reference for building production NestJS backends the right way. It covers the full stack: module organization, DTO validation with class-validator, guards and interceptors, environment config validation at boot, and keeping controllers thin while services own business logic. The structure guidance is opinionated but practical, pushing cross-cutting concerns into common folders and keeping DTOs close to their modules. You'll want this active when setting up new NestJS projects or refactoring messy ones, especially if you're tired of inconsistent error handling or controllers that do too much. The testing and transaction patterns alone save you from common pitfalls.

technical-article-writer

samber/cc-skills

Write compelling technical articles and blog posts for developer audiences. Use this skill whenever the user asks to write a blog post, technical article, or any long-form technical content. Also trigger when the user says 'write about [technical topic]', 'help me draft an article', 'turn this into a blog post', 'write a post about', 'I want to publish something about', or mentions writing for a developer audience. Covers the full pipeline: idea sharpening, hook/title generation, article structure, body drafting, and editing. Even if the user just says 'I want to write about X' without specifying format, use this skill. Do NOT use for platform-specific optimization, newsletter strategy, or ghostwriting voice matching.

perpetuum

zc277584121/perpetuum

Set up, supervise, and control a persistent multi-layer "explore → execute → escalate" agent loop on a project. Use whenever a user asks to keep an agent running on a task across sessions or days — finding bugs, polishing writing, distilling a style, watching feeds, scanning for gaps, or any task whose value grows with how many findings the agent produces. Also use when the user wants to inspect, pause, resume, stop, or send a new instruction to an already-running perpetuum task.
