# @capacitor-firebase/storage[¶](#capacitor-firebasestorage "Permanent link")

Unofficial Capacitor plugin for [Firebase Cloud Storage](https://firebase.google.com/docs/storage/).[1](#fn:1)

[ ![Deliver Live Updates to your Capacitor app with Capawesome Cloud](../../../../assets/external/cloud.capawesome.io/assets/banners/cloud-build-and-deploy-capacitor-apps.69628c3f.png) ](https://cloud.capawesome.io/) 

## Newsletter[¶](#newsletter "Permanent link")

Stay up to date with the latest news and updates about the Capawesome, Capacitor, and Ionic ecosystem by subscribing to our [Capawesome Newsletter](https://cloud.capawesome.io/newsletter/).

## Compatibility[¶](#compatibility "Permanent link")

| Plugin Version | Capacitor Version | Status         |
| -------------- | ----------------- | -------------- |
| 8.x.x          | \>=8.x.x          | Active support |
| 7.x.x          | 7.x.x             | Deprecated     |
| 6.x.x          | 6.x.x             | Deprecated     |

## Installation[¶](#installation "Permanent link")

You can use our **AI-Assisted Setup** to install the plugin. Add the [Capawesome Skills](https://github.com/capawesome-team/skills) to your AI tool using the following command:

`[](#%5F%5Fcodelineno-0-1)npx skills add capawesome-team/skills --skill capacitor-plugins
`

Then use the following prompt:

`` [](#%5F%5Fcodelineno-1-1)Use the `capacitor-plugins` skill from `capawesome-team/skills` to install the `@capacitor-firebase/storage` plugin in my project.
 ``

If you prefer **Manual Setup**, install the plugin by running the following commands and follow the platform-specific instructions below:

`[](#%5F%5Fcodelineno-2-1)npm install @capacitor-firebase/storage
[](#%5F%5Fcodelineno-2-2)npx cap sync
`

Add Firebase to your project if you haven't already ([Android](https://firebase.google.com/docs/android/setup) / [iOS](https://firebase.google.com/docs/ios/setup)).

### Android[¶](#android "Permanent link")

#### Variables[¶](#variables "Permanent link")

If needed, you can define the following project variable in your app’s `variables.gradle` file to change the default version of the dependency:

* `$firebaseStorageVersion` version of `com.google.firebase:firebase-storage` (default: `22.0.1`)

This can be useful if you encounter dependency conflicts with other plugins in your project.

### iOS[¶](#ios "Permanent link")

#### Swift Package Manager[¶](#swift-package-manager "Permanent link")

Add the following to your `capacitor.config.json` (or `capacitor.config.ts`) to avoid a [SwiftPM package identity collision](https://github.com/capawesome-team/capacitor-firebase/issues/959):

`[](#%5F%5Fcodelineno-3-1){
[](#%5F%5Fcodelineno-3-2)  "experimental": {
[](#%5F%5Fcodelineno-3-3)    "ios": {
[](#%5F%5Fcodelineno-3-4)      "spm": {
[](#%5F%5Fcodelineno-3-5)        "packageOptions": {
[](#%5F%5Fcodelineno-3-6)          "@capacitor-firebase/storage": {
[](#%5F%5Fcodelineno-3-7)            "symlink": true
[](#%5F%5Fcodelineno-3-8)          }
[](#%5F%5Fcodelineno-3-9)        }
[](#%5F%5Fcodelineno-3-10)      }
[](#%5F%5Fcodelineno-3-11)    }
[](#%5F%5Fcodelineno-3-12)  }
[](#%5F%5Fcodelineno-3-13)}
`

**Attention**: SPM `packageOptions` support requires Capacitor CLI **8.4.0+**.

## Configuration[¶](#configuration "Permanent link")

No configuration required for this plugin.

## Demo[¶](#demo "Permanent link")

A working example can be found here: [robingenz/capacitor-firebase-plugin-demo](https://github.com/robingenz/capacitor-firebase-plugin-demo)
