process

Extensions to process object.

Process: Main, Renderer

Electron’s process object is extended from the Node.js process object. It adds the following events, properties, and methods:

Events

Event: ‘loaded’

Emitted when Electron has loaded its internal initialization script and is beginning to load the web page or the main script.

It can be used by the preload script to add removed Node global symbols back to the global scope when node integration is turned off:

// preload.js
const _setImmediate = setImmediate
const _clearImmediate = clearImmediate
process.once('loaded', () => {
  global.setImmediate = _setImmediate
  global.clearImmediate = _clearImmediate
})
