AngularFire ❱ Developer Guide ❱ Realtime Cloud Functions # Cloud Functions The Cloud Functions for Firebase client SDKs let you call functions directly from a Firebase app. To call a function from your app in this way, write and deploy an HTTPS Callable function in Cloud Functions, and then add client logic to call the function from your app. [Learn More](https://firebase.google.com/docs/functions/get-started) ## Dependency Injection As a prerequisite, ensure that `AngularFire` has been added to your project via ```bash ng add @angular/fire ``` Provide a Cloud Functions instance in the application's `NgModule` (`app.module.ts`): ```ts import { provideFirebaseApp, initializeApp } from '@angular/fire/app'; import { getFunctions, provideFunctions } from '@angular/fire/functions'; @NgModule({ imports: [ provideFirebaseApp(() => initializeApp(environment.firebase)), provideFunctions(() => getFunctions()), ] }) ``` Next inject it into your component: ```ts import { Component, inject} from '@angular/core'; import { Functions } from '@angular/fire/functions'; @Component({ ... }) export class AppComponent { private functions: Functions = inject(Functions); ... } ``` ## Firebase API The [Firebase API for Cloud Functions documentation](https://firebase.google.com/docs/reference/js/functions) is available on the Firebase website. ## Convenience observables More details coming soon.
