h3-js: React-native won't compile because of the use of h3-js

importing h3-js this way import * as h3 from "h3-js";

would trigger the error below:

[Sat May 08 2021 16:50:27.116]  ERROR    Error: Requiring module "node_modules/h3-js/dist/browser/h3-js.js", which threw an exception: ReferenceError: Can't find variable: document
[Sat May 08 2021 16:50:27.132]  ERROR    ReferenceError: Can't find variable: document

I am wondering if this could be easily fixed? I am reading that there is a node version of h3-js, how can I import it instead of the browser version?

I tried to only import the function I was using at the time but I am still getting the same error

import {geoToH3} from 'h3-js';

I think the error is pointing to this code here in h3-js

  var readAsync;

  {
    if (document.currentScript) {
      scriptDirectory = document.currentScript.src;
    }

    if (scriptDirectory.indexOf("blob:") !== 0) {
      scriptDirectory = scriptDirectory.substr(0, scriptDirectory.lastIndexOf("/") + 1);
    } else {
      scriptDirectory = "";
    }

This issue should be resolved with the most recent 4.1.0 release. I have been able to use the 4.1.0 dist directly in WebWorkers now greatly speeding up computations 😃

With Deno’s recent support for npm packages, you may now use a regular import like

import * as h3 from "npm:h3-js@4.0.1";

Easy enough, but non-standard and won’t help people on other runtimes (and not even Deno Deploy as the feature is experimental). It would be great if h3-js could simply get rid of the document-reference.

It looks like the bug on the Emscripten side (emscripten-core/emscripten#14198) was fixed as of November of last year. Would it be possible to cut a new h3-js release with the latest emscripten, which hopefully will make this library React Native compatible?

I’m trying to use h3-js in a web-worker and I have the same problem. It would be great if a new h3-js release was published with the latest emscripten version
