Describe the `document.navigator` security caveats in the docs

[nasirkhan]

Thanks for building this awesome tool.

I was trying to use it in one of my projects, I am using Vite to build the project.

I added the CSS and used the following code for JS.

<script type="module">
  import { init } from "https://cdn.jsdelivr.net/npm/shareon@2/dist/shareon.es.js";
  // do something
  init();
</script>

After that all the buttons worked, but copy-url throws an error when I click on that button. Even after initialization, it shows a warning ReferenceError: temp0 is not defined. The error

TypeError: navigator.clipboard is undefined
    u https://cdn.jsdelivr.net/npm/shareon@2/dist/shareon.es.js:27
    u https://cdn.jsdelivr.net/npm/shareon@2/dist/shareon.es.js:25
    <anonymous> http://localhost/products/123:417

I am testing from Firefox, I would like to mention that your demo at shareon.js.org/ works fine from the same browser.

Can you please help me to find and fix the issue?

Now that's weird! I'll take a look at it during this week

Although, take a look at this:

Can it be that you just open the HTML file in the browser without actually serving it? If so, this will not work.

Try using vite dev or vite preview to run it on a localhost server. If you publish your website online, it should also work

I was using yarn dev and even used yarn build to build my project. everything else is working fine with this approach. Even other share buttons are working as well. The issue is only with the copy url

[kytta]

Can you provide an example of your setup? Here's my attempt at a MRE: https://stackblitz.com/edit/vitejs-vite-37ttzf?file=index.html,package.json&terminal=dev and the button works here.

Again, if you do not have HTTPS on your website or open it by double-clicking the HTML file (that is, the protocol is file:///), the button will not work. It only works for https:// websites, with the only exception being https://localhost

This works for me when developing Shareon. If you clone the repo and run pnpm dev, it will launch my dev server (on localhost), and the button will work there, too

thanks for looking into the issue. I was running the site from a local virtual host without https. That might be the reason for getting that error. I opened the site via a https URL and it worked perfectly.

You may add this to the doc.

Glad I was able to resolve this! I'll reopen this issue until I've appended to the documentation
