@fedify/debugger: Embedded ActivityPub debug dashboard for Fedify

This package is available since Fedify 2.0.0.

This package provides an embedded real-time debug dashboard for inspecting ActivityPub traces and activities in your federated server app. It works as a proxy that wraps your existing Federation object, intercepting HTTP requests matching a configurable path prefix and serving the debug dashboard, while delegating everything else to the inner federation.

import { createFederation, MemoryKvStore } from "@fedify/fedify";
import { createFederationDebugger } from "@fedify/debugger";

const innerFederation = createFederation<void>({
  kv: new MemoryKvStore(),
  // ... other federation options
});

const federation = createFederationDebugger(innerFederation);

The federation object returned by createFederationDebugger() is a drop-in replacement for the original. You can use it everywhere you would normally use the inner federation object, including with framework integrations such as @fedify/hono and @fedify/express.

[!WARNING] The debug dashboard is intended for development use only. It is strongly recommended to enable authentication if the dashboard is accessible over a network, as it exposes internal trace data.

For more details on configuration, authentication, dashboard pages, and advanced setup, see the Debugging section of the Fedify manual.
