• #8357 ff26dc2 Thanks @dario-piotrowicz! - feat: add new unsafeInspectorProxy option to miniflare

  Add a new unsafeInspectorProxy option to the miniflare worker options, if
  at least one worker has the option set then miniflare will establish a proxy
  between itself and workerd for the v8 inspector APIs which exposes only the
  requested workers to inspector clients. The inspector proxy communicates through
  miniflare's inspectorPort and exposes each requested worker via a path comprised
  of the worker's name

  example:

  import { Miniflare } from "miniflare";
  
  const mf = new Miniflare({
  	// the inspector proxy will be accessible through port 9229
  	inspectorPort: 9229,
  	workers: [
  		{
  			name: "worker-a",
  			scriptPath: "./worker-a.js",
  			// enable the inspector proxy for worker-a
  			unsafeInspectorProxy: true,
  		},
  		{
  			name: "worker-b",
  			scriptPath: "./worker-b.js",
  			// worker-b is not going to be proxied
  		},
  		{
  			name: "worker-c",
  			scriptPath: "./worker-c.js",
  			// enable the inspector proxy for worker-c
  			unsafeInspectorProxy: true,
  		},
  	],
  });

  In the above example an inspector proxy gets set up which exposes worker-a and worker-b,
  inspector clients can discover such workers via http://localhost:9229 and communicate with
  them respectively via ws://localhost:9229/worker-a and ws://localhost:9229/worker-b

  Note: this API is experimental, thus it's not being added to the public documentation and
  it's prefixed by unsafe
