Process not defined when triggering peer.on("connect") and peer.on("data") in reactjs

Hello. I am having issues when implementing simple-peer in reactjs, which is whenever another person joins the room, it cannot trigger these two functions of simple-peer. However my implementation works fine in a non-framework web (using plain javascript and html).
The almost similar issue can be found here:
