Supabase is like the cool, open-source cousin of Google Firebase. It packs a punch with many of Firebase’s features and throws in some extra SQL goodness. When you pair Supabase with a serverless setup, your app can tackle more complex back-end tasks and still keep things real-time.

Serverless architecture is a game-changer. No more babysitting servers because it scales automatically based on demand. Plus, it’s easier on the wallet since you only pay for what you use.

Before diving into the serverless world, you should have a basic grasp of Supabase, AWS Lambda, and the Serverless framework. Some full-stack web development skills will also be super helpful.

First things first, let’s set up a Supabase project. Head over to the Supabase website and create a new project. Generate an API key for your project and keep it safe—you’ll need it later.

Next up, we need to install the Serverless framework. This handy tool automates deployment and runs your services in the cloud. Open your terminal and type:

npm install -g serverless

With the Serverless framework ready to go, let’s create a new service. In your terminal, run:

serverless create --template aws-nodejs --path myService

Swap out "myService" with whatever you want to name your service. This command sets up a new service using the aws-nodejs template in a directory named after your service.

Now, we need to configure AWS credentials in the Serverless framework to deploy your code to AWS. Use this command:

serverless config credentials --provider aws --key YOUR_KEY --secret YOUR_SECRET

Replace YOUR_KEY and YOUR_SECRET with your AWS access key id and secret access key.

Time to bring Supabase into the mix. In the 'myService' folder, replace the content of handler.js with code that connects to your Supabase project. Use the Supabase key you got earlier to authenticate your services.

const { createClient } = require("@supabase/supabase-js")

const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_KEY';
const supabase = createClient(supabaseUrl, supabaseKey);

Finally, let’s deploy your service. Run this command:

serverless deploy

This command deploys your service, including AWS Lambda and AWS Gateway integration. Once it’s done, the terminal will show your service endpoints. You can use these endpoints to interact with your service.

And there you have it! You’ve set up Supabase with a serverless architecture. This guide uses AWS and Node.js, but you can tweak it for other cloud providers and programming languages if needed.
