Dependency Injection

AngularFire allows you to work with Firebase Storage via Angular's Dependency Injection.

As a prerequisite, ensure that AngularFire has been added to your project via

ng add @angular/fire

Provide a Cloud Storage instance in the application's app.config.ts:

import { provideFirebaseApp, initializeApp } from '@angular/fire/app';
import { provideStorage, getStorage } from '@angular/fire/storage';

export const appConfig: ApplicationConfig = {
  providers: [
    provideFirebaseApp(() => initializeApp({ ... })),
    provideStorage(() => getStorage()),
    ...
  ],
  ...
})

Next inject Storage into your component:

import { Component, inject} from '@angular/core';
import { Storage } from '@angular/fire/storage';

@Component({ ... })
export class StorageComponent {
  private storage = inject(Storage);
  ...
}

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/storage' to import { ... } from '@angular/fire/storage' and follow the official documentation.

File Upload Example

import { Component, inject } from '@angular/core';
import { Storage, ref, uploadBytesResumable } from '@angular/fire/storage';

@Component({
    selector: 'app-storage',
    template: `
        <h1>Storage</h1>
        <label for="fileUpload">Choose a File</label>
        <input id="fileUpload" type="file" #upload>
        <button (click)="uploadFile(upload)">Upload</button>
    `,
})
export class StorageComponent {
    private readonly storage: Storage = inject(Storage);

    uploadFile(input: HTMLInputElement) {
        if (!input.files) return

        const files: FileList = input.files;

        for (let i = 0; i < files.length; i++) {
            const file = files.item(i);
            if (file) {
                const storageRef = ref(this.storage, file.name);
                uploadBytesResumable(storageRef, file);
            }
        }
    }
}
