Missing prebuilts ?

[julbd]

Hello,

isolated-vm 6.0.0 was shipped with the following prebuilts :

isolated-vm-v6.0.0-node-v127-darwin-arm64.tar.gz
isolated-vm-v6.0.0-node-v127-linux-arm64.tar.gz
isolated-vm-v6.0.0-node-v127-linux-x64.tar.gz
isolated-vm-v6.0.0-node-v127-linuxmusl-arm64.tar.gz
isolated-vm-v6.0.0-node-v127-linuxmusl-x64.tar.gz
isolated-vm-v6.0.0-node-v134-linux-arm64.tar.gz
isolated-vm-v6.0.0-node-v134-linux-x64.tar.gz
isolated-vm-v6.0.0-node-v134-linuxmusl-arm64.tar.gz
isolated-vm-v6.0.0-node-v134-linuxmusl-x64.tar.gz
isolated-vm-v6.0.0-node-v137-darwin-arm64.tar.gz 

I found that v127 refers to node 22.x and v137 to node 24.x.

• What is the target of node-v134 ?
• Why shipping for node 22 if isolated-vm 6.0.0 is restricted for node >= 24 ?
• Why shipping v137-darwin-arm64 and no other architectures ?

I am missing something about the node ABI versions ?

Thanks

Specifically:

But it would be great to have a correct value for engines.node in package.json.

Currently, the installation is blocked on node 22, unless the package manager ignores the engines (depends on your pm and your settings, but it would be great if it could work for everyone).

What is the target of node-v134 ?

I dug into the version mappings recently during another exploration; but none of those main ones seem to list v134:

We can look up which N-API version corresponds to which node version from the Node.js Releases page:

• https://nodejs.org/en/about/previous-releases

By clicking on 'details' next to the version, and then looking at the listed 'N-API version'; eg.

A list of recent version mappings:

• Node.js v24: v137
• Node.js v23: v131
• Node.js v22 (Jod): v127
• Node.js v21: v120
• Node.js v20 (Iron): v115
• Node.js v19: v111
• Node.js v18 (Hydrogen): v108

v134 was uploaded due to a bug in prebuild: prebuild/prebuild#335. For v6.0.1 I manually renamed the binaries to v137.
