Requiring a module from CustomJS Callback

I’m new to javascript and have a situation where I’d like to use math.js from within a CustomJS callback. What steps do I need to take to hit this dependency? I’ve installed via npm, but simply calling require("mathjs") from the CustomJS source doesn’t work:

Error: Cannot find module ‘mathjs’

My guess is that I’m missing something simple about javascript…

the simplest solution would be to just include a <script src="path/to/math.js> in the HTML document (possibly use a CDN) and then reference math.js from a CustomJS callback by using mathjs global. If you want to to include math.js as a module (which require() implies), then you would have to create a custom bokehjs module bundle, which, I think, is an overkill in this scenario. Obviously a lot depends on what exactly is the goal. If you just want to make it work, then the former solution should be much more straight forward to work out.
