Workers

https://github.com/cloudflare/workers-sdk/blob/main/packages...

The Wrangler, Cloudflare's Developer Platform command-line interface (CLI), allows you to manage Worker projects and has an in-built Miniflare, which runs an HTTP server.

/** * Welcome to Cloudflare Workers! This is your first worker. * * - Run `npm run dev` in your terminal to start a development server * - Open a browser tab at http://localhost:8787/ to see your worker in action * - Run `npm run deploy` to publish your worker * * Learn more at https://developers.cloudflare.com/workers/ */ export interface Env { // Example binding to KV.

Except that there is. Cloudflare is pretty great for free SSL certificates and DNS management, but they also offer a free Workers plan. A Cloudflare worker is basically JavaScript code that runs on Cloudflare's edge network and handles HTTP traffic. You can do a lot with workers, including modifying/rewriting HTML responses. You can probably see where this is going: If a worker can modify HTML responses, then it can inject the umami script into every HTML response.

Cloudflare Workers

And what about the DX of using Workers with Pages?

I tried to use that recently and it was a disaster. I wrote about my experience here:

https://twitter.com/pierbover/status/1641474067013271552

I then opened these two issues:

https://github.com/cloudflare/workers-sdk/issues/2962

https://github.com/cloudflare/workers-sdk/issues/2964

I ended up moving the project over to Netlify + Edge functions. I had it all working in like 5-10 mins as it should. Took me two hours to figure out why Workers weren't working in my Pages project, and could never get Workers working properly with my Astro project.

I think you're working exclusively on the engine of Workers which is really top notch, but Cloudflare really needs to improve the outer layer which affects DX considerably.

TensorFlow.js

Many people seem to be unaware of tensorflow.js, an official JS implementation of TF

https://github.com/tensorflow/tfjs

I'd love to see PyTorch in JS, but I think unless you get it running on the GPU it won't be able to do much.

TensorflowJS GitHub Repository

Also, Tensorflow.js WebGPU backend has been in the works for quite some time: https://github.com/tensorflow/tfjs/tree/master/tfjs-backend-...

It's a pity that tfjs never truly developed any decent ops. E.g. you need lgamma to implement the cap for zero-inflated poisson regression and tfjs simply doesn't have that: https://github.com/tensorflow/tfjs/issues/2011

People have been doing it for long with WebGL, see eg https://github.com/tensorflow/tfjs and https://cloudblogs.microsoft.com/opensource/2021/09/02/onnx-...

thanks, no not unity, going to show it as a demo with threejs + tensorflow on the web. I found a github request to add face orientation https://github.com/tensorflow/tfjs/issues/3835 looks like they assigned someone to add it but doesn't look like its available yet, but there's some posts about the math I can use to get rotations based on some of the landmarks

There already exist a wide variety of neural network inference engines that run in web browsers (e.g. TensorFlow.js and, my personal favorite for use with PyTorch models, ONNX Runtime Web), but pre- and post-processing has always required imperative manipulations on flat buffers rather than a clean ndarray interface.
