Installation

Newest version:

dependencies {
    implementation("io.github.jan-tennert.supabase:coil3-integration:VERSION")
}

Install plugin in main SupabaseClient. See the documentation for more information

val client = createSupabaseClient(
    supabaseUrl = "https://id.supabase.co",
    supabaseKey = "apikey"
) {
    //...
    install(Storage) {
        //your config
    }
    install(Coil3Integration)
}

If you don't have a coil-network artifact in your dependencies, you will need to add it. See the Coil documentation for more information.

Usage

Add Supabase Fetcher to Coil

Create a new ImageLoader with the Supabase Fetcher and a network fetcher.

ImageLoader.Builder(context)
    .components {
        add(supabaseClient.coil3)
        //You also need the add the network fetcher factory if you don't have it already
        //Depending on the network artifact you added, this will be different
        add(KtorNetworkFetcherFactory())
    }
    .build()

You can also replace the default Coil Image Loader in your application. For Compose Multiplatform Applications using the coil-compose dependency, you can use the setSingletonImageLoaderFactory composable function:

setSingletonImageLoaderFactory { platformContext ->
    ImageLoader.Builder(platformContext)
        .components {
            add(supabaseClient.coil3)
            //Your network fetcher factory
            add(KtorNetworkFetcherFactory())
        }
        .build()
}

You call this composable before any Image composable is used. Presumably in your Root composable.

See the Coil documentation for more information.

Display images from Supabase Storage

You can easily create an image request like this:

val request = ImageRequest.Builder(context)
    .data(authenticatedStorageItem("icons", "profile.png")) //for non-public buckets
    .build()

Or if you are using Compose Multiplatform:

AsyncImage(
    model = publicStorageItem("icons", "profile.png"), //for public buckets
    contentDescription = null,
)

The Coil integration will automatically add the Authorization header to the request if the bucket is not public.
