This repository is an open-source Java library for fast and convenient storing and accessing data in your Java applications.

Currently, we support MinIO and Firebase.

How to use

At first, you need to install this library.

With Maven add dependency to your pom.xml.

<dependency>
    <groupId>io.github.ilyalisov</groupId>
    <artifactId>storage</artifactId>
    <version>0.1.0</version>
</dependency>

This library provides simple and convenient usage.

Instantiate a service

You need to create MinIOStorageService object and pass login data for MinIO to the constructor.

public class Main {
    public static void main(String[] args) {
        String host = "http://localhost:9000";
        String rootUser = "rootUser";
        String rootPassword = "rootPassword";
        String bucket = "bucket";

        StorageService storageService = new MinIOStorageServiceImpl(
                host,
                rootUser,
                rootPassword,
                bucket
        );
    }
}

And for Firebase it is a bit different.

public class Main {
    public static void main(String[] args) {
        InputStream inputStream = new ByteArrayInputStream(
                System.getenv("FIREBASE_SECRET").getBytes()
        );
        String bucket = System.getenv("FIREBASE_BUCKET");

        StorageService storageService = new FirebaseStorageServiceImpl(
                inputStream,
                bucket
        );
    }
}

After, you can call available methods and use library.

Save file

To save file just call method save. It will return path to saved file.

public class Main {
    public static void main(String[] args) {
        StorageFile file = new StorageFile(
                "fileName",
                "text/plain",
                new ByteArrayInputStream("...")
        );

        Path path = storageService.save(file);
    }
}

Delete file

You can delete file by its name, name and path, and you can delete entire folder by path.

public class Main {
    public static void main(String[] args) {
        storageService.delete("file.txt");
        storageService.delete("file.txt", Path.of("folder"));
        storageService.delete(Path.of("folder"));
    }
}

Check if file exists

You can check whether file exists or not.

public class Main {
    public static void main(String[] args) {
        boolean file1 = storageService.exists("file.txt");
        boolean file2 = storageService.delete("file.txt", Path.of("folder"));
    }
}

Get file

You can get file from storage by calling corresponding methods.

public class Main {
    public static void main(String[] args) {
        Optional<StorageFile> file = storageService.find("file.txt");
        Optional<StorageFile> file2 = storageService.find("file.txt", Path.of("folder"));
        List<StorageFile> files = storageService.findAll(
                Path.of("folder"),
                new Page(0, 10)
        );
    }
}
