I have to kill the application before it consumes everything.
Electron applications like VS Code are an exception and slightly gives me hope.
Going to be working on an Electron app, so I'm curious about what optimizations have been made there.
I've found keeping as precious little of the work in the render process as possible has helped a great deal. Send everything to the main process and use the event/messaging system to update the state. Then things that you're used to doing to maintain application performance in a web browser apply. Keep the compute in the back as much as possible.
And depending on the task, offload compute to a native module [if you're capable and] if the expense between NodeJS <> native module is worth it (more intense compute tasks).
There's probably more and more experienced advice out there, but this is my experience so far.
They just run more efficient software on top of electron than others do.
