🚀 Example in bare HTML files
You can easily import the NPM package from a CDN, and sign a Nanopublication from a simple index.html file. There is no need to install the npm package in this case, but you will need to initialize the WebAssembly binary when using it on the client (for JS running in the browser):
index.html
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="utf-8" />
<title>Testing Nanopub JS</title>
</head>
<body>
<pre><code id="rdf-text"></code></pre>
<script type="module">
import init, { Nanopub, NpProfile } from "https://unpkg.com/@nanopub/sign";
// Change the RDF and private key as you wish
const rdfStr = `@prefix : <http://purl.org/nanopub/temp/mynanopub#> .
@prefix np: <http://www.nanopub.org/nschema#> .
@prefix npx: <http://purl.org/nanopub/x/> .
