Unlock the Power of Serverless Computing: Integrating Supabase with Cloudflare Workers
Cloudflare Workers is a revolutionary serverless computing platform that enables developers to deploy and run JavaScript code across a global edge network. With over 200 data centers worldwide, this platform provides exceptional performance, low latency, and efficient scaling for web applications. Unlike traditional serverless functions, Cloudflare Workers runs on the Chrome V8 isolation engine, eliminating concerns such as the cold-start issue.
Recently, Cloudflare introduced a new database integration option, allowing developers to connect their preferred databases to Workers. In this article, we’ll explore the process of setting up, configuring, and deploying a Supabase database on Cloudflare Workers.
Getting Started
To follow along with this tutorial, you’ll need:
- A working knowledge of JavaScript
- Node.js installed
- Experience with Supabase and Cloudflare Workers setup is preferred, but not required
What is Supabase?
Supabase is an open-source backend as a service (BaaS) platform that offers developers a comprehensive set of tools and services to build applications with a database backend. Built on top of PostgreSQL, a popular and robust open-source relational database management system, Supabase streamlines the development process by effectively managing routine tasks associated with data storage, authentication, and real-time updates.
Setting Up Supabase
To demonstrate the integration procedure, we’ll create a Postgres database with Supabase and then deploy it on Cloudflare Workers. Start by signing up for a Supabase account or logging in to access your dashboard. Click the New Project button to initiate a new project and enter the required information. Supabase will automatically generate an API for your project, and you’ll need to save the API anon key in a safe location.
Creating a Table in Supabase
After successfully deploying the project, navigate to the Table Editor and create a new table. For this example, let’s name the table “movies.” Add the necessary columns and click Save. You can now add rows of data to the table, either by importing data from a CSV file or by manual entry.
Setting Up Cloudflare Workers
To set up a workers project in your local development environment and deploy it to Cloudflare Workers, create a new account on the Cloudflare Workers platform or log in to the dashboard. Instead of deploying a sample project, you can create and deploy your own using Cloudflare Wrangler.
Setting Up a Project with Wrangler
Install Wrangler globally on your computer using the command npm install -g @cloudflare/wrangler. Then, use the Wrangler package to automatically generate a boilerplate project by running the command wrangler generate movies-app. This will create a movies-app folder and launch the Wrangler command-line wizard to assist in creating a project based on your preferences.
Deploying to Cloudflare Workers
Deploying your application to a Worker is as easy as running npx wrangler deploy in the terminal. If you’re using Wrangler for the first time, you’ll need to authenticate your account before deploying your project.
Integrating Supabase
After deploying your project, return to the Cloudflare Workers dashboard and navigate to the Overview page to view your newly deployed project. Clicking on the project name to preview it will result in an error because the integration type for the project has not been set. To set it, select the Settings tab, then click on Integration in the left nav, and choose Add Integration from the Supabase option.
On the Integration page, grant permission for your Worker to connect to your Supabase account. Next, select a project and configure your profile secrets, including your Supabase URL and Key. Finally, click the Add integration button at the bottom of the page. If you click the dashboard Preview link, you should see a list of movies from your Supabase table.
You’ve successfully integrated Supabase with Cloudflare Workers, unlocking the benefits of both platforms.
