From lang
Full-stack JavaScript development covering backend (NestJS/Express), frontend (React), deployment (CI/CD), and quality; also covers JavaScript language fundamentals (types, closures, prototypes, async/await, modules, and metaprogramming). MUST load when package.json contains Express, NestJS, or similar backend frameworks. Covers API design, state management, caching, and testing. Also use when working with JavaScript language-level concerns — type coercion, scoping, this binding, Promise patterns, Proxy/Reflect, or iterator protocols. Also covers V8 engine internals (hidden classes, inline caches, string/number repr), event loop model, JS/Node error model, and Express 5 + Drizzle ORM CRUD APIs.
