Using JSPM to generate import map for ES modules.

Getting started : JSPM

Install jspm globally (or locally, if so run npx jspm instead of jspm):

npm install -g jspm

Create a directory, install npm dependencies (es-module-shims is an importmap polyfill that jspm includes by default):

mkdir imtest
cd imtest
npm install es-module-shims @atcute/oauth-browser-client

Create index.html with a script that imports stuff (JSPM also supports scripts in external files):

$ cat > index.html
<!doctype html>
<script type="module">
  import { configureOAuth } from '@atcute/oauth-browser-client';
  console.log(configureOAuth );
</script>

Finally, resolve the importmap and update index.html:

jspm link --provider nodemodules index.html -o index.html
