Electron availability

[WimTibackx]

Hi,

I came across this repository when wanting to port a selenium-based script I had lying around to an obsidian plugin. I did some further investigation of my own, but it seemed to be that importing selenium to an obsidian plugin would be difficult/impossible because of it's reliance on node:events and dynamic imports.

Afterwards, I wondering whether it was possible to access the internal electron in Obsidian. Turns out it is! Can be tested via devtools by accessing the electron global variable. To use the full swathe of electron APIs, you may need to access electron.remote.

For example, the electron repo has this example for rendering an url on an offscreen webview and grabbing a screenshot of it. While I didn't try the screenshot myself (as it uses node:fs) I can run that code sample by adjusting electron to electron.remote. As a rough demo, dumping the following code in obsidian devtools console opens a hidden window, loads github.com, executes some javascript on that page and returns the result of that to you. Optionally, you can open devtools and avoid closinfg the window to verify results.

let offsc = new electron.remote.BrowserWindow({ webPreferences: { offscreen: true }, show: false /*true*/ })
offsc.loadURL('https://www.github.com')
//offsc.webContents.openDevTools();
offsc.webContents.on('did-finish-load', (event) => {
  console.log('did-finish-load', event);
  offsc.webContents.executeJavaScript(`let i = 0; i++; i++; i;`).then(result => {
    console.log('result from within is ' + result);
    offsc.close();
  });
})
offsc.webContents.setFrameRate(60)

I've further tried wrapping that idea into cleaner promises and into an obsidian plugin and can confirm it actually works from the plugin-system. Figured that might be useful info for the creator and anyone coming across this repo.

Have a nice day!
