I am building an EelectronJS app and successfully release it as an executable Windows program.
But the problem is when the app is already running, if I double-click again that .exe file, the second window of this app is running, but buggy. I don’t want it. So here is the solution:
This main.js file is my solution when I need to prevent multiple instances of ElectronJS app to run at same time.
const { app, BrowserWindow } = require('electron')
const gotTheLock = app.requestSingleInstanceLock()
if (!gotTheLock) {
app.quit()
} else {
app.on('ready', createWindow)
}
function createWindow () {
// Create the browser window.
let win = new BrowserWindow({ width: 1024, height: 720 })
// and load the index.html of the app.
win.loadFile('index.html')
}
app.on('window-all-closed', () => {
app.quit()
})
loading...
