Example

import io.supabase.StorageClient;
import io.supabase.api.IStorageFileAPI;
import io.supabase.data.bucket.CreateBucketResponse;
import io.supabase.data.file.*;

import java.io.File;
import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ExecutionException;

public class Main {
    public static void main(String[] args) {
        String url = System.getenv("SUPABASE_URL");
        String serviceToken = System.getenv("SUPABASE_SERVICE_TOKEN");

        StorageClient storageClient = new StorageClient(serviceToken, url);

        // Interact with Supabase Storage
        CompletableFuture<CreateBucketResponse> res = storageClient.createBucket("examplebucket");

        // Do something on future completion.
        res.thenAccept((bucketRes) -> {
            IStorageFileAPI fileAPI = storageClient.from(bucketRes.getName());
            try {
                // We call .get here to block the thread and retrieve the value or an exception.
                // Pass the file path in supabase storage and pass a file object of the file you want to upload.
                FilePathResponse response = fileAPI.upload("my-secret-image/image.png", new File("file-path-to-image.png")).get();

                // Generate a public url (The link is only valid if the bucket is public).
                fileAPI.getPublicUrl("my-secret-image/image.png", new FileDownloadOption(false), new FileTransformOptions(500, 500, ResizeOption.COVER, 50, FormatOption.NONE));

                // Create a signed url to download an object in a private bucket that expires in 60 seconds, and will be downloaded instantly on link as "my-image.png"
                fileAPI.getSignedUrl("my-secret-image/image.png", 60, new FileDownloadOption("my-image.png"), null);

                // Download the file
                fileAPI.download("my-secret-image/image.png", null);

            } catch (InterruptedException | ExecutionException e) {
                throw new RuntimeException(e);
            }
        });
    }
}

Local development

For testing the application you will need to spin up the docker compose found in the infra folder.

1. cd infra.
2. cp .env.example .env
3. Fill in the values of the .env
4. docker compose up -d

Then you can test the application with the default values already in the test files.
