import() is disallowed on ServiceWorkerGlobalScope by the HTML specification.

Hello,

I'm trying to use your package to run hnswlib in a Chrome extension's background script. When I call loadHnswlib I get the error:

import() is disallowed on ServiceWorkerGlobalScope by the HTML specification.

Note that I don't get this error when importing transformers.js and it's successfully working in the background script, so it's not generally failing to do imports.

Any idea why your module might be different? I'm stumped why one module would import and work but not another, given this error message.

The reason you have this error is because @ShravanSunder is doing a dynamic import here

hnswlib-wasm/src/index.ts

Line 126 in 8a34923

const temp = await import('./hnswlib.mjs');

Browser extension service workers do not support dynamic import - source

There are two methods of importing scripts into a service worker: the import statement and the importScripts() method. Note that import(), often called a dynamic import, is not supported.

I'm also building a browser extension and needed a faster vector search approach (instead of my linear O(n) search) - https://twitter.com/clamentjohn/status/1678096766204248067

Currently the library doesn't support workers. Its not something i've looked into on how to load wasm files into service workers.

we'll have to use fetch and a relative or remote url to load wasm into a serviceworker.

Feel free to make a PR. Just make sure to add tests, that all tests pass and follow the same code convention. 😄
