问题 New to Electron and building menus I'm trying to see if I can separate a MenuItem to prevent an enormous file but I'm having issues. For example I've separated the menu code outside of main.js and I moved menu in a renderer directory within a Menu directory.

问题 There is an async function ( send ) in which if the msg attribute is not defined, another function ( getNextProcess ) sets its value. getNextProcess performs a database query within a Promise.

问题 I'm currently working on an Electron.js app and I'm stuck on an asynchrony problem. I have three function (downdloadFile()) inside three if statements to be executed in sequence but they run asynchronously; I already tried using async/await but it didn't worked. Here's my code: ipcMain.on('play',(event,payload) => { launcherConfig.savedRam = payload.savedRam; launcherConfig.savedMaxPermSize = payload.savedMaxPermSize; if(payload.selectedPacket) { //FIRST IF if (!fs.existsSync(launcherDir + "\
