Cross-Origin Storage API Extension

[nico-martin]

This should not be merged yet.

Instead its an experimantal implementation of the Cross-Origin Storage API that the Google Chrome Team is working on: https://github.com/explainers-by-googlers/cross-origin-storage

To test is you need to install the Cross-Origin Storage API extension in your browser: https://github.com/web-ai-community/cross-origin-storage-extension?tab=readme-ov-file

I've released a little library that I think can be super neatly integrated in Transformers.js for also storing the Wasm files dynamically in Cross-Origin Storage.

import { NPMSHA256HashFetcher } from './index.js';

const fetcher = new NPMSHA256HashFetcher();

const resources = [
  "@huggingface/transformers/dist/ort-wasm-simd-threaded.jsep.wasm",
  /* All other resources from npm… */
];

const results = await fetcher.getHexHashForResource(resources);

And there you have the evergreen SHA-256 hashes, so whenever the Wasm on npm changes, the hashes will automatically be adjusted, so you can store the files in Cross-Origin Storage conveniently.

It's obviously a standalone library, but there's a GUI if you want to play with it:
