nodejs/node v21.6.0

2024-01-15, Version 21.6.0 (Current), @RafaelGSS

on GitHub

New connection attempt events

Three new events were added in the net.createConnection flow:

• connectionAttempt: Emitted when a new connection attempt is established. In case of Happy Eyeballs, this might emitted multiple times.
• connectionAttemptFailed: Emitted when a connection attempt failed. In case of Happy Eyeballs, this might emitted multiple times.
• connectionAttemptTimeout: Emitted when a connection attempt timed out. In case of Happy Eyeballs, this will not be emitted for the last attempt. This is not emitted at all if Happy Eyeballs is not used.

Additionally, a previous bug has been fixed where a new connection attempt could have been started after a previous one failed and after the connection was destroyed by the user.
This led to a failed assertion.

Changes to the Permission Model

Node.js 21.6.0 comes with several fixes for the experimental permission model and two new semver-minor commits.
We're adding a new flag --allow-addons to enable addon usage when using the Permission Model.

$ node --experimental-permission --allow-addons

Contributed by Rafael Gonzaga in #51183

And relative paths are now supported through the --allow-fs-* flags.
Therefore, with this release one can use:

$ node --experimental-permission --allow-fs-read=./index.js

To give only read access to the entrypoint of the application.

Contributed by Rafael Gonzaga and Carlos Espa in #50758

Support configurable snapshot through --build-snapshot-config flag

We are adding a new flag --build-snapshot-config to configure snapshots through a custom JSON configuration file.

$ node --build-snapshot-config=/path/to/myconfig.json

When using this flag, additional script files provided on the command line will
not be executed and instead be interpreted as regular command line arguments.

These changes were contributed by Joyee Cheung and Anna Henningsen in #50453
