How Adapters Work

Adapters translate REROUTE's file-based routes into framework-specific routes:

from fastapi import FastAPI
from reroute.adapters import FastAPIAdapter
from pathlib import Path

app = FastAPI()
adapter = FastAPIAdapter(
    fastapi_app=app,
    app_dir=Path(__file__).parent / "app"
)
adapter.register_routes()

Common Features

The FastAPI adapter supports:

  • File-based routing discovery - Automatic route registration from folder structure
  • HTTP method mapping - GET, POST, PUT, DELETE, PATCH, OPTIONS
  • Lifecycle hooks - before_request, after_request, on_error
  • Decorator integration - Rate limiting, caching, validation
  • Custom configuration - Framework-specific settings
  • Security headers - OWASP-compliant security headers (v0.2.0+)

Why FastAPI?

REROUTE focuses exclusively on FastAPI because it offers:

Feature FastAPI
Async Support Full async/await support
Auto API Docs Built-in Swagger UI and ReDoc
Performance Excellent (on par with NodeJS and Go)
Type Safety Full Python type hints support
Validation Automatic request/response validation
Learning Curve Medium - easy to learn

Framework-Specific Guide

Custom Adapters

You can create custom adapters for other frameworks by extending the base adapter class. See the Adapters API Reference for the adapter interface.
