## What it does

The skill covers the usual Nginx jobs: putting a reverse proxy in front of a backend, spreading traffic across services, terminating SSL/TLS, HTTP/2 and gRPC, caching with compression, rate limiting and DDoS protection, URL rewriting and routing. API gateway patterns get their own section.

What you get is a minimal `nginx.conf` example with worker settings, logging and an `http` block, plus deeper material in the `references/` directory: production configuration, an HTTPS server with load balancing, a setup script and monitoring. A practices list sits alongside it — HTTP/2, strong ciphers, upstream connection pooling, `stub_status` or prometheus, security headers, `least_conn`. The don'ts are spelled out too: weak ciphers, caching authenticated responses, exposing backends directly, serving HTTP and HTTPS without a redirect.

Six platforms are supported, and each one has its own install command and file path, so a config written for one does not carry over to another by itself. Weak ciphers and cached sensitive data are the mistakes that reach real users, so read the generated file before you deploy it.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill nginx-configuration -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/nginx-configuration/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nginx-configuration/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill nginx-configuration -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/nginx-configuration/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill nginx-configuration -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/nginx-configuration/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aj-geddes/useful-ai-prompts nginx-configuration
```

2. **Manually: put the files in place**
- File: `.github/skills/nginx-configuration/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill nginx-configuration -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aj-geddes/useful-ai-prompts --path skills/nginx-configuration
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/nginx-configuration/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill nginx-configuration -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aj-geddes/useful-ai-prompts/tree/HEAD/skills/nginx-configuration/SKILL.md

## When to use it
- stand up a reverse proxy in front of a backend
- split traffic across several services
- terminate SSL/TLS with strong ciphers
- turn on response caching and compression
- throttle request rates and blunt simple DDoS

## Example prompts
- Write an Nginx config that reverse-proxies to my app on port 3000
- Set up load balancing across two backends with `least_conn`
- Add SSL/TLS termination and redirect HTTP to HTTPS

## Overview

Master Nginx configuration for production-grade web servers, reverse proxies, load balancing, SSL termination, caching, and API gateway patterns with advanced performance tuning.

## When to Use

- Reverse proxy setup
- Load balancing between backend services
- SSL/TLS termination
- HTTP/2 and gRPC support
- Caching and compression
- Rate limiting and DDoS protection
- URL rewriting and routing
- API gateway functionality

## Quick Start

Minimal working example:

```nginx
# /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
worker_rlimit_nofile 65535;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
    worker_connections 4096;
    use epoll;
    multi_accept on;
}

http {
    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    # Logging
    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for"';

    log_format upstream_time '$remote_addr - $remote_user [$time_local] '
                            '"$request" $status $body_bytes_sent '
                            '"$http_referer" "$http_user_agent" '
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Use HTTP/2 for performance
- Enable SSL/TLS with strong ciphers
- Implement proper caching strategies
- Use upstream connection pooling
- Monitor with stub_status or prometheus
- Rate limit to prevent abuse
- Add security headers
- Use least_conn load balancing
