Electron 39 Compatibility Issue with rclnodejs - new node() Constructor Fails

[alexlzg]

Description
The rclnodejs module fails to initialize properly in Electron 39.x, while it works correctly in Electron 31.7.7. Specifically, calling new node() constructor results in an error in Electron 39, but works fine in the older version.

• Library Version: 1.8.0
• ROS Version: jazzy
• Platform / OS: ubuntu 24

Steps To Reproduce

source /opt/ros/jazzy/setup.bash
main/index.ts
import * as rclnodejs from 'rclnodejs'

app.whenReady().then(() => {
const mainWindow = createWindow()

rclnodejs.init().then(() => {
const node = rclnodejs.createNode('publisher_example_node')
})
npm run dev

Expected Behavior
The new node() constructor should work consistently across supported Electron versions (at least within the same major version range).

Actual Behavior
Node constructor fails in Electron 39.x but works in Electron 31.7.7.

Well this is a known issue, that's why we pin the Electron version in the demos:

rclnodejs/electron_demo/manipulator/package.json

Line 27 in a45c45a

"electron": "^31.7.7"

But we can investigate any solution there.

Hi @alexlzg I re-tested with the demo, it seems workable now

What I did:

1. Upgrade Electron in package.json to "electron": "^40.0.0"
2. Run npm install && npm run start

https://github.com/RobotWebTools/rclnodejs/blob/develop/test/electron/test_usability.js is added to validate the Electron + rclnodejs env.
