window.request is undefined

[maskedjellybean]

Following the Usage instructions it seems like I should be able to avoid using Browserify by loading the browser-request JS file directly in HTML like so <script src="node_modules/browser-request/index.js"></script> and then in another JS file that is loaded beneath it, using browser-request by calling window.request (HTML comment in Usage instructions reads "Assigns the module to window.request"). Apparently I am misinterpreting that because window.request is undefined. Can someone please explain to me how to use this without needing to use Node's require() and Browserify? I have confirmed that node_modules/browser-request/index.js is being loaded by the browser.

Thank you.
