workerd VS miniflare

Standards bodies only standardize things after they've been proven to work. You can't standardize a new idea before offering it to the market. It's hard enough to get just one vendor to experiment with an idea (it literally took me years to convince everyone inside Cloudflare that we should build Durable Objects). Getting N competing vendors to agree on it -- before anything has been proven in the market -- is simply not possible.

But the Durable Objects API is not complicated and there's nothing stopping competing platforms from building a compatible product if they want. Much of the implementation is open source, even. In fact, if you build an app on DO but decide you don't want to host it on Cloudflare, you can self-host it on workerd:

https://github.com/cloudflare/workerd

In any case, I welcome this initiative with my open hands and look forward all the cool apps that people will now build with this!

workerd

I think this is for people who want to run their own cloudflare workers (sort of) and since nobody wants to run full node for that, they want a small runtime that just executes js/wasm in an isolated way. But I wonder why they don't tell me how I can be sure that this is safe or how it's safe. Surely I can't just trust them and it explicitly mentions that it still has file IO so clearly there is still work I need to do customize the isolation further. But then they don't show any info on that core usecase. But then that's probably because they don't really want you to use this to run it on your own, they are selling you on running things on their edge platform called "Wasmer Edge". So that's probably why this is so light on information.. the motivation isn't to get you to use this yourself, just to use this their hosted edge platform. But then I wonder why I wouldn't just use https://github.com/cloudflare/workerd which is also open source. Surely that is fast enough? If not then it should show some benchmarks?

i love how the main reference for workerd can be just one capnp file.

https://github.com/cloudflare/workerd/blob/main/src/workerd/...

this changed my world how i think about computing on the web.

if there was just a good enough js library as for lua and you could directly send capnp messages to workerd instead of always going through files. I guess one day i have to relearn c++ and understand how the internals actually work.

A significant chunk of it is open source: https://github.com/cloudflare/workerd/

Some of the configuration files for applications wind up being an entire language unto themselves, e.g., https://github.com/cloudflare/workerd/blob/1b5057f2bfcfedf146f6f79ff04e99903d55412b/src/workerd/io/compatibility-date.capnp

Edge runtimes are very good alternatives to containers that shouldn't be dismissed for "not being containers". They're often faster, more scalable, and cheaper than containers. Them being so lightweight also enable a "nanoservice architecture" – being able to run every service on a single computer instead of running different services on different computers and having to deal with network latency and unreliability.

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.
