wrangler-legacy VS miniflare

Recently, as a weekend hobby project, I created a Slack app development framework for Cloudflare Workers and Vercel Edge Functions.

Edge Runtime has become a buzzword in the technology landscape, driving dynamic, low-latency functions in platforms from AWS Lambda@Edge and Cloudflare Workers to Vercel Edge. Emphasizing its importance, Vercel recently changed "experimental-edge" to "edge", signaling official support in their popular Next.js framework.

It seems like the perfect usecase for Cloudflare Workers.

For this tutorial, I’ll use Cloudflare Workers as they’re really fast and easy to set up, but you can use pretty much any other serverless provider with support for JS.

Cloudflare has a wonderful serverless platform called Cloudflare Workers that allows you to write code without worrying about underlying hardware or software. Yesterday, they announced that Workers now have the ability to connect directly over TCP sockets. I want to use this feature to send an APRS packet to CWOP.

Sounds doable with Cloudflare Workers

Recently Cloudflare introduces Miniflare. As its name suggests, Miniflare is a feature-rich but miniature version of Cloudflare worker. Miniflare is a simulator that provides an environment for developing and testing Cloudflare worker scripts locally. Miniflare is written in typescript and supports most of the Cloudflare worker features like the KV database, durable objects, WebSockets, etc.

Another implementation of the above is Cloudfare workers you might be capable of grasp some ideas from here https://miniflare.dev

Is there an ETA on Miniflare v3? Ran into a problem recently using overlapping keys with forward slashes as they were not sanitized properly: https://github.com/cloudflare/miniflare/issues/167

The KV API is only available on Cloudflare Workers. But, during development, Rakkas runs our app on Node.js. Fortunately, the Miniflare project has a KV implementation for Node. The other two packages that we've installed (@miniflare/kv and @miniflare/storage-memory) are what we need to be able to use the KV API during development. Let's create a src/kv-mock.ts file and create a local KV store to store our ublog posts ("twits") while testing:

I used hono (a wrapper around miniflare) to handle some of the boilerplate around request and routing logic. It's also refreshingly fast! 🔥

The simple explanation is that I'm proposing use of the Service Worker API. Cloudflare offers a flat, free, 100k requests a day if you can keep it cutting edge, has local development and testing options with miniflare and a key/value (KV) store.

When we run the dev script, this will ensure that the local runtime environment Miniflare will bind a KV with the name sessionStorage to our Pages function.

Slshx is a library for building strongly-typed Discord commands (https://discord.com/developers/docs/interactions/application...) that run on Cloudflare Workers (https://workers.cloudflare.com/), using a React-inspired syntax (hooks and JSX). It supports all Discord command types/options, autocomplete and interactive message components. During development, it automatically deploys your commands whenever you change your code.

I created this because I think Cloudflare Workers are a great fit for hosting Discord commands, but there wasn't an easy way to get started that had a fun development experience. I also wanted to see what a Miniflare-first (https://github.com/cloudflare/miniflare) library could look like.
