open - node__inspector.d.ts - Node

function open

Usage in Deno

```typescript import { open } from "node:node__inspector.d.ts"; ```



open(port?: number,
host?: string,
wait?: boolean,
): Disposable

Activate inspector on host and port. Equivalent to `node --inspect=[[host:]port]`, but can be done programmatically after node has started. If wait is `true`, will block until a client has connected to the inspect port and flow control has been passed to the debugger client. See the [security warning](https://nodejs.org/docs/latest-v22.x/api/cli.html#warning-binding-inspector-to-a-public-ipport-combination-is-insecure) regarding the `host` parameter usage.
