This article is a summary of my experience learning about Supabase for my research. First, I created a Supabase account at Supabase Dashboard. You can sign up using your email and password, GitHub account, or other SSO options. After completing the registration details, you can create a project in the Supabase dashboard.

Once you’ve created your project, go to Supabase Dashboard. The first thing you’ll need to do is install the Supabase CLI on your local machine. For reference, I’m using a Mac.

brew install supabase/tap/supabase

For more details, you can check Supabase CLI Getting Started Guide. After installing the CLI, you can log in to Supabase directly from your terminal.

supabase login

Supabase will redirect you to your browser to log in and sync your account from the browser to your local machine. After that, you can create a function project like this:

supabase functions new <function-name>

When you open the project, it will look like this:

After some searching, I found that I needed to install the Deno extension in VSCode.

Deployment:

Deploying this serverless function is quite simple. Just run the following command:

supabase functions deploy pilkada-mobile-svc --project-ref <id>

When the deployment is successful, your terminal will show something like this:
