Install

You can use our AI-Assisted Setup to install the plugin. Add the Capgo skills to your AI tool using the following command:

npx skills add https://github.com/cap-go/capacitor-skills --skill capacitor-plugins

Then use the following prompt:

Use the `capacitor-plugins` skill from `cap-go/capacitor-skills` to install the `@capgo/capacitor-photo-library` plugin in my project.

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

npm install @capgo/capacitor-photo-library
npx cap sync

Usage

import { Capacitor } from '@capacitor/core';
import { PhotoLibrary } from '@capgo/capacitor-photo-library';

const { state } = await PhotoLibrary.requestAuthorization();
if (state === 'authorized' || state === 'limited') {
  const { assets, hasMore } = await PhotoLibrary.getLibrary({
    limit: 100,
    thumbnailWidth: 256,
    thumbnailHeight: 256,
  });

  const gallery = assets.map(asset => ({
    id: asset.id,
    fileName: asset.fileName,
    thumbnailUrl: asset.thumbnail
      ? asset.thumbnail.webPath ?? Capacitor.convertFileSrc(asset.thumbnail.path)
      : undefined,
    photoUrl: asset.file
      ? asset.file.webPath ?? Capacitor.convertFileSrc(asset.file.path)
      : undefined,
  }));

  console.log('Loaded', gallery.length, 'items. More available?', hasMore);
}

const picked = await PhotoLibrary.pickMedia({
  selectionLimit: 3,
  includeVideos: true,
});

console.log('User selected', picked.assets.length, 'items');

The native implementations cache exported files inside the application cache directory. You can safely delete the photoLibrary folder under the cache if you need to free up space.

API

checkAuthorization()

checkAuthorization() => Promise<{ state: PhotoLibraryAuthorizationState; }>

Returns the current authorization status without prompting the user.

Returns: Promise<{ state: PhotoLibraryAuthorizationState; }>


requestAuthorization()

requestAuthorization() => Promise<{ state: PhotoLibraryAuthorizationState; }>

Requests access to the photo library if needed.

Returns: Promise<{ state: PhotoLibraryAuthorizationState; }>


getAlbums()

getAlbums() => Promise<{ albums: PhotoLibraryAlbum[]; }>

Retrieves the available albums.

Returns: Promise<{ albums: PhotoLibraryAlbum[]; }>


getLibrary(...)

getLibrary(options?: GetLibraryOptions | undefined) => Promise<GetLibraryResult>

Retrieves library assets along with URLs that can be displayed in the web view.

Param Type
options GetLibraryOptions

Returns: Promise<GetLibraryResult>


getPhotourl(/sitelet?url=https%3A%2F%2Fgithub.com%2FCap-go%2F...)

getPhotoUrl(options: { id: string; }) => Promise<PhotoLibraryFile>

Retrieves a displayable URL for the full resolution version of the asset. If you already called getLibrary with includeFullResolutionData, you normally do not need this method.

Param Type
options { id: string; }

Returns: Promise<PhotoLibraryFile>


getThumbnailurl(/sitelet?url=https%3A%2F%2Fgithub.com%2FCap-go%2F...)

getThumbnailUrl(options: { id: string; width?: number; height?: number; quality?: number; }) => Promise<PhotoLibraryFile>

Retrieves a displayable URL for a resized thumbnail of the asset.

Param Type
options { id: string; width?: number; height?: number; quality?: number; }

Returns: Promise<PhotoLibraryFile>


pickMedia(...)

pickMedia(options?: PickMediaOptions | undefined) => Promise<PickMediaResult>

Opens the native system picker so the user can select media without granting full photo library access. The selected files are copied into the application cache and returned with portable URLs.

Param Type
options PickMediaOptions

Returns: Promise<PickMediaResult>


getPluginVersion()

getPluginVersion() => Promise<{ version: string; }>

Get the native Capacitor plugin version

Returns: Promise<{ version: string; }>
