Alright, let's get started! First, log in to your Supabase account. Once you're in, click on "New Project" to create a fresh project.

Next up, head over to GitHub. Click on the "+" sign in the upper right corner of your dashboard. Then, go to "Your repositories" and hit "New" to create a new repository.

Now, let's get things rolling locally. Open your terminal and run "git init" to initialize your project. After that, link it to your GitHub repo with "git remote add origin {Github repo url}".

Time to set up the Supabase CLI. Run "npm install -g supabase" to install it globally. Once that's done, log in with your Supabase credentials using "supabase login".

With the CLI ready, create a new Supabase project by running "supabase init". Easy peasy!

Let's get those files up to GitHub. Run "git add .", then "git commit -m 'init'", and finally "git push origin master". Done and done.

Now, we need to set some environment variables. In your GitHub repository, go to "Settings" and then "Secrets". Add your Supabase project URL and Supabase service role key here.

Let's automate things a bit. Create a new GitHub action that triggers whenever you push to the master branch. Go to "Actions" in your repository and create a new workflow using the Node.js template.

Now, let's add some scripts to your workflow. These scripts will install dependencies, build your app, and deploy it to Supabase. Use "npm run build" to build your app, and "npm run deploy" to deploy it.

Finally, let's test everything. With your next commit and push to the master branch, your workflow should run, building and deploying your app. Check the status under "Actions" in your GitHub repository to confirm everything's working smoothly.
