Guides development of Fastify Node.js backend servers and REST APIs using TypeScript or JavaScript. Use when building, configuring, or debugging a Fastify application — including defining routes, implementing plugins, setting up JSON Schema validation, handling errors, optimising performance, managing authentication, configuring CORS and security headers, integrating databases, working with WebSockets, and deploying to production. Covers the full Fastify request lifecycle (hooks, serialization, logging with Pino) and TypeScript integration via strip types. Trigger terms: Fastify, Node.js server, REST API, API routes, backend framework, fastify.config, server.ts, app.ts.
Build Next.js 16 apps with App Router, Server Components/Actions, Cache Components ("use cache"), and async route params. Includes proxy.ts (replaces middleware.ts) and React 19.2. Use when: building Next.js 16 projects, or troubleshooting async params (Promise types), "use cache" directives, parallel route 404s (missing default.js), or proxy.ts CORS.
Verify and configure HTTP security headers (CSP, HSTS, CORS, X-Frame-Options, etc). Checks current configuration and generates framework-specific fixes.
Write secure-by-default Node.js and TypeScript applications following security best practices. Use when: (1) Writing new Node.js/TypeScript code, (2) Creating API endpoints or middleware, (3) Handling user input or form data, (4) Implementing authentication or authorization, (5) Working with secrets or environment variables, (6) Setting up project configurations (tsconfig, eslint), (7) User mentions security concerns, (8) Reviewing code for vulnerabilities, (9) Working with file paths or child processes, (10) Setting up HTTP headers or CORS.
Expert knowledge for Azure Energy Data Services development including troubleshooting, decision making, architecture & design patterns, security, configuration, integrations & coding patterns, and deployment. Use when configuring ADME tiers, partitions & CORS, Reservoir DDMS, ACL/legal tags, or Geospatial CZ on AKS, and other Azure Energy Data Services related development tasks. Not for Azure Data Explorer (use azure-data-explorer), Azure Synapse Analytics (use azure-synapse-analytics), Azure Data Factory (use azure-data-factory), Azure Databricks (use azure-databricks).
Implements authentication, authorization, encryption, secrets management, and security hardening patterns. Use when designing auth flows, managing secrets, configuring CORS, implementing rate limiting, or when asked about JWT, OAuth, password hashing, API keys, RBAC, or security best practices.
Debug FastAPI applications systematically with this comprehensive troubleshooting skill. Covers async/await issues, Pydantic validation errors (422 responses), dependency injection failures, CORS configuration problems, database session management, and circular import resolution. Provides structured four-phase debugging methodology with FastAPI-specific tools including uvicorn logging, OpenAPI docs, and middleware debugging patterns.
This skill deploys frontend and full-stack projects to EdgeOne Pages (Tencent EdgeOne). It should be used when the user's primary intent is to deploy, publish, ship, host, launch, go live, or release a new version — e.g. "deploy my app", "publish this site", "push this live", "create a preview deployment", "deploy to EdgeOne", "ship to production", "上线", "发布", "发一版", "重新部署". Do NOT trigger when deployment is only mentioned as a secondary step (e.g. "write an API and deploy it" — primary intent is writing code, use edgeone-pages-dev). Do NOT trigger for post-deployment runtime errors (e.g. CORS issues, 500 errors after deploy — use edgeone-pages-dev for troubleshooting).
Debug Express.js and Node.js applications with systematic diagnostic techniques. This skill provides comprehensive guidance for troubleshooting middleware execution issues, routing problems, CORS errors, async error handling, memory leaks, and unhandled promise rejections. Covers DEBUG environment variable usage, Node Inspector with Chrome DevTools, VS Code debugging, Morgan request logging, and diagnostic middleware patterns. Includes four-phase debugging methodology and common error message reference.
Connect React/Next.js apps to Encore.ts backends.
Debug network issues using browser tools and network analysis. Diagnose connection problems, latency, and data transmission issues.
Validate and implement HTTP security headers to protect web applications.
