(V8 developer here.) Your analysis seems correct: Electron 9.0 enabled V8 pointer compression, and pointer compression implies that the maximum heap size is capped at 4GB (because compressed pointers use 32 bits per pointer).

Pointer compression is a build-time flag for V8. Embedders can freely choose whether to enable it or not, but the decision has to be made at build time, it can't be made at runtime. If you build your own Electron, you can change the configuration accordingly and recompile to turn off pointer compression. Node.js decided to disable pointer compression, which is why bigger heaps work there.

I suppose you could also ask the Electron project to provide prebuilt binaries without pointer compression, but I have no idea how likely they are to accommodate such a request.

Note that due to the memory-saving effects of pointer compression (which is why the feature exists!), a 4GB compressed heap is roughly equivalent to a 6GB uncompressed heap (the exact numbers depend on what your app is doing).

Electron uses MacOS local frameworks, that weirdly enough, you don't seem to have on your computer.

Try to list your frameworks to confirm this: ls -al /System/Library/Frameworks/

If you don't have any, or miss some of them (depending on your OS version), chances are you won't be able to build anything native at all, and your system should be all broken by now (plus, CoreFoundation is the most important framework): a clean install of the latest XCode won't install those frameworks back AFAIK.

Then, your options are:

• reinstall macOS
• get those framework from another mac using the same macOS version
• grab them from your recovery

The code looks fine and should be executed when running. You might be looking at the wrong console? The log statements should appear in the console of the renderer window. To open the Developer Tools, you can press Cmd + Opt + I (macOS) and Ctrl + Shift + I (Windows).

You can find more information about debugging Electron applications in their documentation and the Developer Tools in Chrome's documentation.

At first remove nodejs from your computer:

i've downgrade my electron version to 9.3.1 and now my project working normally. You can find specific information about electron and spectron version that can support each other from electron-userland/spectron

That's because your output html in production should be located elsewhere, btw I'm using angular with electron and the output is in the dist folder, but I don't use url.format: try with mainWindow.loadURL(`file://$_dirname/index.html`) or if you have a dist folder mainWindow.loadURL(`file://$_dirname/dist/index.html') Try changing also app.whenReady() by app.on("ready",createWindow) Hope it works afterwards

You're confusing your main and renderer processes. With Electron, all code that is responsible for your UI, i.e. the JavaScript attached to the HTML loaded in the BrowserWindows run in renderer processes, all other code, which, for example, is responsible for opening the windows or for setting up you app runs in the main process.

In this main process, you cannot use DOM-specific globals because the main process is a pure Node.js thing. What you wanted to do with jQuery, i.e.
