Can it be installed by submodules?

[mig82]

I'd just need the definition for Greatest Common Divisor. Is it possible to install a submodule of MathJS?

Yes, if you're using ES6 imports you can just import the functions you need. The regular functions like the following are relatively large since they include BigNumber, Matrix, etc:

import { gcd } from 'mathjs'

If you only need a number implementation I think the following will work for you:

import { gcd } from 'mathjs/number'

For more info see:

Thank you @josdejong. I forgot to mention I'm using this in Node, so I was looking for something like a partial installation —like npm install mathjs.gcd. The way Lodash does it. I take it that's not possible or you would have mentioned it.

No, not really, though you can look in /lib/plain/number/arithmetic for example, it's quite small.

Just curious: if you're using node.js, a larger file is normally not an issue like in the browser where bundles must be as small as possible. Why are you concerned with loading a small file only?

@josdejong my use case is lambda functions, so creating the smallest bundles is beneficial for speed

[josdejong]

Yes that makes sense Nick 👍

In my case I'm building a mobile app using Temenos (formerly Kony) Quantum and I'm just abusing NPM to install dependencies. So also, the smaller the codebase the better.

Thanks for your feedback Miguelángel. For web and mobile, the bundle size matters a lot indeed, only for nodejs (server side) it's less important.
