Installation

x^2 + x/4 + 3*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.
