问题 I have a form with two different buttons, one to download data (from Firestore) and one to display it in realtime. For this I have two functions (Angular 8), where one uses valueChanges() to display data in realtime and the other uses get() to get the same data and download it. The user can choose to specify search more or less, so I have quite a lot of code for making the query and this needs to be doubled if I am to use both get() and valueChanges() . I am therefore wondering if someone can

问题 I'm working on Admin module of an android application. Admin module is a web-app based on Angular. Firebase auth(Email/password) is used to sign-In as a admin.

问题 First time using firestore and I'm getting this error. It seems to be a problem with Ivy, from my research. I don't have a lot of experience modifying tsconfig.app.json, which is the direction I've been pointed to, following other answers. The only thing I was able to modify from the original project was to use Angular Fire 6 instead of 5, which I had done initially to follow a tutorial. Here's package.json: { "name": "language", "version": "0.0.0", "scripts": { "ng": "ng", "start": "ng serve

I have researched for almost 3

问题 I am developing an App in Ionic 4 using Angular and I am using Firebase to store and retrieve data using AngularFire. My App displays list of events from database that span over two days from current time and has an option for registering for events. Events that had start time in past and start time in future(3+ days from now) are not shown in the App. Currently, I am using client's system time but the problem with this is user can change device time to past to see all the events in the past

问题 I am looking to increment several counters with Firebase transactions and also add set a new value in firebase. The key being I want to make sure it is all successful or not save any of the data. I imagine this would be best done with promises? Unfortunately I'm not very familiar with them So far I have: $scope.addNewPost = function() { var ref = new Firebase(FBURL).child('/posts').push(); var onComplete = function(error) { if (error) { alert('Error: Something went wrong when creating your
