Cache Supabase data at the Edge with Cloudflare Workers and KV Storage

The “Edge” is where you write and store your code where your data is being produced. This allows for a quick and efficient data transfer, eliminating or severely reducing lag.

Supabase is a suite of open-source tools wrapping a PostgreSQL database. It provides the building blocks of an app - database hosting, auth, file storage, real-time, and edge functions - so we can focus on what makes our app unique.

Cloudflare Workers are serverless functions that run at the Edge! In this course, we will use the Wrangler CLI tool for interfacing with your Cloudflare account and creating or publishing your Workers.

KV Storage is a cache that Cloudflare makes available to our Workers. It replicates across multiple CDN nodes, making it super performant to cache data.

Combined, these three things give you the benefits of that reduced lag in a smooth and streamlined process.

Throughout this course, Jon will teach you how to create a small blog that hits the key points of how to:

• Query Supabase from Cloudflare Workers
• Read and write KV Storage cache from Cloudflare Worker
• Cache Supabase response at the Edge with KV storage

And more!
