[FIXED] What event should I use for closing client websocket in Electron application?

Issue

I have Electron application. There is websocket connection between server and client side of electron app (another words, I use websocket on index.html).

I need to close websocket connection, when user closes the application. What event should I use for it?

There is mainWindow.on('closed', () => { }); but I have no access to browser code at this point.

Solution

You should use IPC (Internal Process Communication). In the electron framework, there are two processes:

• Main (The main process creates web pages by creating BrowserWindow instances.)
• Renderer (The main process manages all web pages and their corresponding renderer processes)

These two can communicate together using IPC. For more details see docs
