Release notes
Experimental Network Inspection Support in Node.js
This update introduces the initial support for network inspection in Node.js.
Currently, this is an experimental feature, so you need to enable it using the --experimental-network-inspection flag.
With this feature enabled, you can inspect network activities occurring within a JavaScript application.
To use network inspection, start your Node.js application with the following command:
$ node --inspect-wait --experimental-network-inspection index.js
Please note that the network inspection capabilities are in active development.
We are actively working on enhancing this feature and will continue to expand its functionality in future updates.
- Network inspection is limited to the http and https modules only.
- The Network tab in Chrome DevTools will not be available until the feature request on the Chrome DevTools side is addressed.

New option for vm.createContext() to create a context with a freezable globalThis
Node.js implements a flavor of vm.createContext() and friends that creates a context without contextifying its global object when vm.constants.DONT_CONTEXTIFY is used. This is suitable when users want to freeze the context (impossible when the global is contextified i.e. has interceptors installed) or speed up the global access if they don't need the interceptor behavior.
