When to use this

Use this approach when you want a config-first Cloudflare Worker gateway behavior that is already implemented in the repository and covered by tests or canonical examples.

What this does not do

• It does not add unsupported product features such as rate limiting, caching, API keys, analytics, or OpenAPI generation.

• It does not replace upstream application logic that still belongs in your services.

• It does not remove the need to validate environment variables, bindings, and route intent before deploy.

Repo-grounded example

{
  "authorizer": {
    "type": "auth0",
    "domain": "$env.AUTH0_DOMAIN",
    "client_id": "$env.AUTH0_CLIENT_ID",
    "client_secret": "$secrets.AUTH0_CLIENT_SECRET",
    "redirect_uri": "https://api.example.com/api/v1/auth0/callback",
    "callback_uri": "https://app.example.com/auth/callback",
    "jwks_uri": "https://tenant.us.auth0.com/.well-known/jwks.json",
    "scope": "openid profile email"
  },
  "paths": [
    {
      "method": "GET",
      "path": "/api/v1/auth0/callback",
      "integration": { "type": "auth0_callback" }
    }
  ]
}

This example is grounded in the current implementation shape: JSON config, path-based routing, optional auth, request mapping, and Worker-native integrations.

Troubleshooting

• Confirm the route path and HTTP method match what the worker receives.

• Confirm the config source is the one you expect: local file, KV, or SAG_API_CONFIG_JSON.

• Confirm required bindings and environment variables are present before debugging downstream logic.

• Run the existing tests in the main gateway repo when a config change appears correct but runtime behavior disagrees.
