You can customize the lifecycle implementation logic on an application-by-application basis in app.js. The following example only prints the corresponding logs in the lifecycle function:
// app.js
export default {
onCreate() {
console.info('Application onCreate');
},
onDestroy() {
console.info('Application onDestroy');
},
}
