Application Lifecycle

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');
    },
}
