Within a renderer you can access NodeJS APIs directly. The main process shouldn’t be used for any significant computation, as it will block GPU paints and cross-process synchronisation.
The other main difference is Electron bundles a known set of APIs, given the known Chromium version. There’s such a huge variance of supported features across the embedded web views.
Yes, this is the best benefit of elecrron: you dont have to trouble shoot 10s of OS webview versions and their ixremental suppory, especially with MacOS.
But it is right that the ui for elwctron has to use a IPC layer to get a node backend running. However, chrome is moving a lot of things like FilesystemAPI into browsers so there may be a day were nodejs is dropped in favor of a sandboxed chromium.
