AngularFire ❱ Developer Guide ❱ 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.

## 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 `app.config.ts`:
```ts
import { provideFirebaseApp, initializeApp } from '@angular/fire/app';
import { provideFunctions, getFunctions } from '@angular/fire/functions';
export const appConfig: ApplicationConfig = {
providers: [
provideFirebaseApp(() => initializeApp({ ... })),
provideFunctions(() => getFunctions()),
...
],
...
})
```
Next inject `Functions` into your component:
```ts
import { Component, inject} from '@angular/core';
import { Functions } from '@angular/fire/functions';
@Component({ ... })
export class AppComponent {
private functions = inject(Functions);
...
}
```
## Firebase API
AngularFire wraps the Firebase JS SDK to ensure proper functionality in Angular, while providing the same API.
Update the imports from `import { ... } from 'firebase/functions'` to `import { ... } from '@angular/fire/functions'` and follow the official documentation.
