Production-Grade Proxy Server

A config-driven HTTP proxy with enterprise-grade observability, security, and reliability—purpose-built for internal API gateways.

Why This Exists

The Problem

You need a proxy that:

✅ Routes requests intelligently (not just round-robin)
✅ Validates requests before they hit your backend
✅ Rate limits abusive clients
✅ Fails gracefully when upstreams are down
✅ Gives you deep observability (not just access logs)
✅ Can be configured by non-engineers

Nginx/HAProxy: Fast but config is cryptic, no custom logic
Kong/Tyk: Powerful but heavyweight, complex to operate
Roll your own: Easy to start, hard to make production-ready

This Proxy

A middle ground: production-ready proxy in Node.js with:

Config-driven routing (YAML, not code)
Built-in security (SSRF protection, rate limiting, auth)
Deep observability (structured logs, Prometheus metrics, correlation IDs)
Reliability patterns (circuit breakers, retries, timeouts)
Developer-friendly (JavaScript, not Lua or C++)

When to Use This

✅ Good Fit

Internal API gateway for microservices
Development/staging proxy with observability
Custom routing logic that's easier in JavaScript than Nginx config
Request transformation (header manipulation, body validation)
Team has Node.js expertise

❌ Not a Good Fit

Public-facing edge proxy (use Nginx/Cloudflare)
Ultra-high throughput (> 10K req/sec per instance)
Ultra-low latency (P99 < 5ms required)
Service mesh (use Istio/Linkerd)

What Makes This Production-Ready

Most "proxy tutorials" stop at forwarding requests. This goes further:

🔒 Security

SSRF Protection: Block access to cloud metadata, private IPs
Authentication: API key validation (HMAC-SHA256)
Rate Limiting: Token bucket with Redis backend
Input Validation: Header sanitization, payload size limits
Allow-list: Deny by default, explicit upstream allow-list

See full threat model →

🎯 Reliability

Circuit Breakers: Stop hitting failing upstreams
Retries: Exponential backoff with jitter
Timeouts: Request, connection, DNS, header, idle
Backpressure: Reject when overloaded (don't OOM crash)
Connection Pooling: Reuse TCP connections

See traffic control docs →

📊 Observability

Structured Logs: JSON logs with correlation IDs
Metrics: Prometheus-compatible (RPS, latency histograms, error rates)
Health Checks: Liveness, readiness, deep health
Tracing: Request flow across services (correlation IDs)
Real-Time Metrics: NATS JetStream streaming with SSE
Metrics Database: PostgreSQL storage for historical analysis
Admin Dashboard: React-based UI with live metrics visualization

See observability docs →

⚙️ Operability

Config Hot Reload: Update routes without restart
Graceful Shutdown: Drain connections before exit
Error Handling: Fail fast on bad config (don't serve traffic)
Kubernetes-Ready: Health probes, resource limits, signals
Admin UI: Web-based management console
Webhook System: Event-driven notifications with retry logic
Database-Backed Config: PostgreSQL for routes, API keys, webhooks

Quick Start

1. Install

git clone https://github.com/tapas100/flexgate-proxy.git
cd flexgate-proxy
npm install

2. Setup Database

# Install PostgreSQL (if not already installed)
brew install postgresql  # macOS
# or
sudo apt-get install postgresql  # Linux

# Create database
createdb flexgate

# Run migrations
psql -d flexgate -f migrations/001_initial_schema.sql
psql -d flexgate -f migrations/002_migration_tracking.sql

psql -d flexgate -f migrations/006_fix_webhook_deliveries_fk.sql
psql -d flexgate -f migrations/008_ai_incident_tracking.sql

3. Setup NATS JetStream (for real-time metrics)

# Using Docker
docker run -d --name nats-jetstream \
  -p 4222:4222 -p 8222:8222 \
  nats:latest -js

# Or using Podman
podman run -d --name flexgate-nats \
  -p 4222:4222 -p 8222:8222 -p 6222:6222 \
  -v ~/flexgate-data/nats:/data:Z \
  nats:2.10-alpine -js -sd /data

4. Environment Variables

# Copy example .env
cp .env.example .env

# Edit .env with your settings
DATABASE_URL=postgresql://localhost/flexgate
DATABASE_USER=flexgate
DATABASE_PASSWORD=your-password
REDIS_URL=redis://localhost:6379
NATS_URL=nats://localhost:4222
PORT=3000

5. Configure Routes

# config/proxy.yml
upstreams:
  - name: "example-api"
    url: "https://api.example.com"
    timeout: 5000
    retries: 3

routes:
  - path: "/api/*"
    upstream: "example-api"
    auth: required
    rateLimit:
      max: 100
      windowMs: 60000

security:
  allowedHosts:
    - "api.example.com"
  blockedIPs:
    - "169.254.169.254"  # AWS metadata

6. Build Admin UI

cd admin-ui
npm install
npm run build
cd ..

7. Run with Docker/Podman (Recommended)

Simple one-command startup:

# Start all services (FlexGate, PostgreSQL, Redis, NATS, Prometheus, Grafana, HAProxy)
npm run start:all

# Check status
npm run status

# Stop all services
npm run stop:all

# Restart all services
npm run restart:all

What it does:

✅ Starts 8 containers (PostgreSQL, Redis, NATS, 2× FlexGate apps, HAProxy, Prometheus, Grafana)
✅ Waits for all services to be healthy
✅ Verifies port accessibility
✅ Shows access URLs and status

Access Points:

## Performance

| Metric | Value | Comparison |
|--------|-------|------------|
| **Throughput** | 4.7K req/sec | Nginx: 52K (11x faster) |
| **P95 Latency** | 35ms | Nginx: 8ms (4x faster) |
| **P99 Latency** | 52ms | Nginx: 12ms (4x faster) |
| **Memory** | 78 MB | Nginx: 12 MB (6x smaller) |
| **Proxy Overhead** | ~3ms | (14% of total latency) |

**Why slower than Nginx?**
- Node.js (interpreted) vs C (compiled)
- Single-threaded vs multi-threaded
- GC pauses

**Why use it anyway?**
- Custom logic in JavaScript (not Nginx config)
- Better observability
- Shared code with backend
- Faster development

Deployment

Podman (Recommended)

For high-performance production deployments (>10K req/sec), use HAProxy + Podman:

# Quick start with Makefile
make build    # Build container image
make start    # Start all services
make stats    # View HAProxy dashboard

# Or use podman-compose directly
podman-compose up -d

# Access services
# HAProxy: http://localhost:8080
# Stats: http://localhost:8404/stats (admin/admin)
# Prometheus: http://localhost:9090
# Grafana: http://localhost:3001 (admin/admin)

Features:

HAProxy data plane (>10K req/sec, <10ms latency)
Rate limiting: 1000 requests per 10 seconds per IP
Circuit breaker: automatic health checks every 2s
Load balancing across 2+ backend instances
Prometheus metrics + Grafana dashboards
Rootless, daemonless container runtime

📘 See haproxy/README.md for complete HAProxy documentation 📘 See haproxy/PODMAN_SETUP.md for Podman setup guide

Standalone (Development)

For development or testing without HAProxy:

# Build image
npm run podman:build

# Run standalone
podman run -d -p 3000:3000 \
  -v $(pwd)/config:/app/config:Z \
  -e NODE_ENV=production \

Error rate
Circuit breaker state
Rate limit hits

Alerts

What This Proxy is NOT

| ❌ Not This | ✅ Use Instead | |------------|---------------| | CDN / Edge cache | Cloudflare, Fastly | | Service mesh | Istio, Linkerd | | Raw performance proxy | Nginx, HAProxy, Envoy | | Public-facing API gateway | Kong, Tyk, AWS API Gateway | | Load balancer | HAProxy, AWS ALB |

When to Replace This

Consider switching to Nginx/Envoy when:

Throughput > 10K req/sec per instance needed
P99 latency < 10ms required
No custom logic needed (pure reverse proxy)
Team lacks Node.js expertise

Failure Modes

Upstream Down

Circuit breaker opens → Fast-fail with 503
↓
Retry every 30s (half-open state)
↓
If success → Circuit closes

Proxy Overloaded

Queue fills → Backpressure kicks in
↓
Reject low-priority routes
↓
Sample logging aggressively
↓
If still overloaded → Reject all with 503

Redis Down

Rate limiter falls back to local state
↓
Less accurate (per-instance limits)
↓
But service stays up

Config Error

Config validation fails → Startup blocked
↓
Old config still serving (hot reload)
↓
Alert fires → Engineer fixes config

Key principle: Fail closed, degrade gracefully

Observability - Logging, metrics, tracing
Traffic Control - Rate limiting, circuit breakers, retries
Trade-offs - Architectural decisions
Benchmarks - Performance numbers

CI/CD

FlexGate uses Jenkins (not GitHub Actions) for all build, test, and publish pipelines.

| Trigger | Pipeline | |---|---| | Push to main | Lint → Type-check → Test → Build → npm publish | | Merge PR into main | Same as above |

The full pipeline is defined in Jenkinsfile at the repo root.

Jenkins credentials required:

NPM_TOKEN — npm publish token (add under Jenkins → Manage Credentials)

See .github/WORKFLOWS.md for full Jenkins setup instructions.
