Hello,

I am using this library with svelte and snowpack.

snowpack build runs fine but If i snowpack dev, the following line will throw an error:

import Peer from 'peerjs'
const peer = new Peer()

It throws the following error:

Uncaught ReferenceError: parcelRequire is not defined

Source:

http://localhost:8080/web_modules/peerjs.js [:4:889]

ReferenceError: parcelRequire is not defined
    at parcelRequire.EgBh (http://localhost:8080/web_modules/peerjs.js:4:889)

I found a fix:
In your index.html, or the main html page (template.html sometimes), put this in the <head> tag:

<script>
    var parcelRequire;
</script>

I got this error when using electron-builder in build mode and @arnu515 's fix solved it for me. Just adding this to help the next person keyword search this solution faster. :)

I swear this will sound like a joke but when I use @arnu515's answer I get prompted to print the web page.

Sometimes this happens when you do python and js together. You might have added a print instead of a console.log. The former statement prompts you to print the page. @ColleSerre

Confirm this solution works for Svelte and SvelteKit which use ViteJS.

This has been solved in v1.4.
Importing PeerJS should work with Snowpack, Vite, and Svelte.
