Electron's IPC Not Sending/Receiving

Written February 2018

Having problems sending and receiving data via Electron’s IPC module? This might be the culprit. To use IPC, you need to make sure that your listener window did-finish-load. Otherwise, your data will just fade into the ether.

Main
yourWindow.webContents.on('did-finish-load', () => {
	yourWindow.webContents.send('testChannel', 'Hello world!')
})
Renderer
ipcRenderer.on('testChannel', (event, data) => {
	console.log(data)
})
