I am trying to import bigdecimal, but I ran into an issue that calling

var bigdecimal = require('bigdecimal')

But in browser I am getting

(index):89 Uncaught ReferenceError: require is not defined

I've tried multiple different approaches to this but I'm not exactly sure what to do. I tried using requireJS and browserify and following the documentation but I'm not exactly sure what the issue is and I keep getting that require is not defined.
