B4A Library [B4X] Supabase - The Open Source Firebase alternative

Supabase is an open source Firebase alternative. It provides all the backend services you need to build a product. Supabase uses Postgres database with real-time capabilities. Basically, supabase provides an interface to manage postgres database that you can use to create table and insert, edit and delete data in the table.

We can use REST API or client libraries from supabase to access the data in the postgres database. Supabase is not just about accessing the database. it also provides some solutions out of the box such as Authentication, File Storage and Real-time capabilities.

I am a huge fan of this project and wanted to develop a client library for B4X 2 years ago. With supabase you can develop an online app without having your own backend, no VPS or other server is needed. No matter how many users the app has, the API can scale.

A big goal of the client library for b4x is to be listed on the website among the programming languages that have a community client library. But until then there is still a lot to do.

    • Options_FileSizeLimit (Limit As Int) As Supabase_StorageBucket
    • Options_isPublic (isPublic As Boolean) As Supabase_StorageBucket
      The visibility of the bucket. Public buckets don't require an authorization token to download objects, but still require a valid token for all other operations. By default, buckets are private.

Contain resizes the image to maintain it's aspect ratio while fitting the entire image within the width and height. Fill resizes the image to fill the entire width and height. If the object's aspect ratio does not match the width and height, the image will be stretched to fit.
      <code>cover</code>

      Only for UploadFile and UpdateFile
      When upsert is set to true, the file is overwritten if it exists. When set to false, an error is thrown if the object already exists. Defaults to false.
    • Path (FileName As String) As Supabase_StorageFile
      The file path, including the file name. Should be of the format `folder/subfolder/filename.png`. The bucket must already exist before attempting to upload.
