Ionic PWA how to handle installbeforeprompt


Hi, I am developing a PWA and I want to defer the default app install banner event. In the index.html file I called the installbeforeprompt event. Now how can i access the JS variable in the typescript file to trigger back the event. Is this the right way or we can handle it in some other way. Please suggest. Thanks


Finally found a solution by declaring the javascript variable inside the typescript file as
delcare var VARIABLENAME : any;
