Answer 1

You could use the js spread operator and put that inside the query snapshot so using a bit of your code...

    async get_the_posts(){
        this.Post_collection = this.afs.collection('posts'); 
        return this.Posts = await this.Post_collection.onSnapshot(querySnapshot =>{
                        let arr = []
                        querySnapshot.forEach(function (doc) {
                            arr.push({id:doc.id, ...doc.data()});

                        });
                        return arr
        })
    }
