peerjs_min is not a constructor error when initialising Peer

[arnu515]

I'm using the Svelte framework with Rollup bundler (the default that comes with Svelte). I installed peerjs with:

npm i peerjs

And when I import it,

import Peer from "peerjs";
const peer = new Peer();

I get the error

parcelRequire is not defined

I found a temporary fix, i.e. to define it manually in index.html

<script>
     var parcelRequire;
</script>

But now, I'm getting a different error:

peerjs_min is not a constructor

I am using typescript, so I tried adding "esModuleInterlop": true to my tsconfig.json, but that did nothing.

Can you please help me? My rollup config is the default that came with Svelte. Many thanks!

So I found a temporary fix, i.e. to use window.Peer instead of importing it. This is a really bad fix and I would appreciate it if anyone else would help me :)

I was happily using peerjs in react until a few days ago.. now, with latest @1.4.1

In a clean npx create-react-app (npm 8.10, react 18.1.0)
npm i peerjs
import Peer from "peerjs";
new Peer();
throws Uncaught TypeError: peerjs__WEBPACK_IMPORTED_MODULE_4__ is not a constructor

Reverting back to1.3.2 resolves the issue for me for now:
npm r peerjs
rm -rf node_modules/
npm i peerjs@1.3.2

Thanks for your work!

I have upgraded peerjs to version 1.4.2 then another issue hits me:

Uncaught TypeError: Cannot read properties of undefined (reading 'browser')

Hey @ckqbao. Oh no. I’ll look into it. Can you tell me how to reproduce this?
Maybe open a new issue, so others can find it.

I just use peerjs normally and it works on version 1.3.2. I dont know if any one has the same issue
