comparisons

🧮 Comparisons

Currently, expressions support =, >=, <=, > and < operators. Optionally, you can include a second constructor argument for changing the locale (the default is "en"). Any expressions that do not match a recognized operation get stripped out and are assumed to pass. For simply matching if a property exists, use the =* expression.

Don't worry about type casting—we'll handle that for you.

// @TODO yarn add comparisons
const Comparison = require('comparisons');

const tests = ['foo=bar', 'num>=2'];
const stub = { foo: 'bar', num: 3 };
const runner =  new  Comparison(tests);
runner.eval(stub); // returns true or false
runner.query(); // returns a Mongo friendly query
