What problem does it solve? Setting up production frontend infrastructure requires juggling nginx or Caddy configs, CI/CD pipelines, Docker images, hosting platforms, and zero-downtime strategies, and small mistakes like missing try_files rules or wrong cache headers cause broken routes and stale assets. ## Core Features & Use Cases - Web Server Configuration: Production-ready nginx and Caddy configs covering SPA routing, reverse proxies, SSL/TLS with Let's Encrypt, gzip/Brotli compression, rate limiting, and split cache headers. - CI/CD Pipelines: Complete GitHub Actions and GitLab CI workflows with lint, test, build, Docker push, environment protection, PR previews, and Slack notifications. - Docker & Zero-Downtime Deployment: Multi-stage Dockerfiles, Docker Compose production setups, PM2 process management, and blue-green deployment scripts with health checks and instant rollback. - Use Case: You need to deploy a React SPA to a VPS. Use this Skill to generate an nginx config with SPA fallback and immutable asset caching, a GitHub Actions pipeline that builds and pushes a Docker image, and a blue-green deploy script that switches traffic only after health checks pass. ## Quick Start Ask the assistant to generate a production nginx configuration and GitHub Actions pipeline for deploying your SPA with zero-downtime blue-green releases.
