Middleware

The PRX gateway uses a composable middleware stack to handle cross-cutting concerns like authentication, rate limiting, CORS, and request logging.

Middleware Stack

Requests pass via le middleware stack in order:

1. Request logging -- log incoming requests with timing
2. CORS -- handle cross-origin resource sharing headers
3. Authentication -- validate bearer tokens or API keys
4. Rate limiting -- enforce per-client request limits
5. Request routing -- dispatch vers le appropriate handler

Authentication Middleware

[gateway.auth]
enabled = true
method = "bearer"  # "bearer" | "api_key" | "none"
token_secret = "your-secret-key"

Limiteation de debit

[gateway.rate_limit]
enabled = true
requests_per_minute = 60
burst_size = 10

CORS

[gateway.cors]
allowed_origins = ["https://app.example.com"]
allowed_methods = ["GET", "POST", "PUT", "DELETE"]
allowed_headers = ["Authorization", "Content-Type"]
max_age_secs = 86400

Request Logging

All API requests sont journalises with method, path, status code, and response time. Log level peut etre configured:

[gateway.logging]
level = "info"  # "debug" | "info" | "warn" | "error"
format = "json"  # "json" | "pretty"
