mathjs-webpack-loader

loader for mathjs parsed expression

Installation

npm install --save-dev mathjs-webpack-loader && npm install --save mathjs

Usage

expressions.mathjs

x^2 + x/4 + 3*y
x + y

webpack.config.js

module.exports = {
	module: {
		rules: [
			{
				test: /\.mathjs?$/,
				loader: 'mathjs-webpack-loader'
			}
		]
	}
};

index.js

import expressions from 'expressions.mathjs';
import mathjs from 'mathjs';

const instance = mathjs.create();
const compiled = expressions(instance).map(exp => exp.compile());

console.log(compiled[0].eval({x: 4, y: 1})); // 20
console.log(compiled[1].eval({x: 1, y: 1})); // 2

If only one expression contains in *.mathjs file, then it will be return instead of array. Loader returns function which contains only one parameter - mathjs instance, see configuration.
