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

npm test
npm run test:coverage
RUN_LOCAL_WORKER_E2E=true npm run test:e2e

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.
