Some stuff are not found, like filter()

I’m looking into typescript just now, I just saw that name a couple of times (my project is in javascript anyway) and the error is still there even without the “: Object”.

Not only the type annotations but also the class properties are invalid syntax in JavaScript, so you have to move the property declarations to the constructor (you could check the linked post for more details):

I guess that you have to move the declaration of the class properties to the constructor. Below I made some changes to the code of the workaround that you’re using that might resolve the issue. Make sure to accordingly update the other files in your project too.

Alternatively you could try to convert your project to TypeScript following the instructions in this post.

How about the other question?

I’m not sure what data are you getting back from Firebase but assuming that it’s a collection/dictionary then you can convert it to array this way:

firebase.database().ref('/desideri').on('value', (snapshot) => {
	const objUser = snapshot.val();
	// this is now bound to the component using the fat arrow =>
	console.log(objUser);//this.events.publish('user:update', objUser);

        // NOTE: Assuming that objUser is a Firebase collection/dictionary, i.e.:
        //   {
        //     'firebase_unique_id_1': { ... },
        //     'firebase_unique_id_2': { ... },
        //     // ...
        //   }
        // Convert the Firebase collection/dictionary to array:
        if (objUser) {
            this.risultati = [];
	    this.risultatiKey = Object.keys(objUser);

            for (let id of this.risultatiKey) {
                  this.risultati.push(objUser[id]);
            }
        }
});
