When not to use Deno ☄️

• supabase

  767 65,869 10.0 TypeScript

  The open source Firebase alternative.

  

Database reads are expensive and slow. There's a multitude of other reasons why caching is essential, but for the project I'm working on I'm using supabase and their free tier supports only a limited amount of bandwidth. To avoid any rate-limiting I added a Redis layer in front of it to reduce the number of queries that hit the database directly.

• Redis

• Express

  673 63,771 8.3 JavaScript

  Fast, unopinionated, minimalist web framework for node.

  

Though any traditional server environment will enable this, I used Node as it's close to Deno and simple to use. With a few lines of code, an express server that creates a single client on start will enable any incoming request to reuse the same connection. Adding some simple routing to detect request params and respond with what Redis returns then lets allows the cache requests in Deno to be swapped with GET requests to this server.
