Thanks for the tutorial, just had to add a pipe around the map…

this.tasks = this.db
.collection(config.collection_endpoint)
.snapshotChanges()
.pipe(
map(actions => {
return actions.map(a => {
//Get document data
const data = a.payload.doc.data() as Task;
//Get document id
const id = a.payload.doc.id;
//Use spread operator to add the id to the document data
return { id, …data };
});
})
);
