Previously, we used to save the window's state in the renderer process `beforeunload` event handler: because of the synchronous nature of event handlers and the asynchronous design of IndexedDB, this could potentially not save anything if windows close fast enough to prevent IndexedDB from committing the pending transaction containing the state. (Ref.: https://mzl.la/2bXCXDn) With this commit, we will intercept the `before-quit` events on `electron.app` and the `close` event on `BrowserWindow` (which will fire respectively before quitting the application and before closing a window), and prevent them from performing the default action. We will then ask each renderer process to save its state and, finally, close the window and/or the app.
Atom is a hackable text editor for the 21st century, built on Electron, and based on everything we love about our favorite editors. We designed it to be deeply customizable, but still approachable using the default configuration.
