Be There.js

A Javascript presence assertion library

Null references suck. Constantly checking function parameters uglies up code in a hurry. There are other resources of parameter validation but they don't do much to streamline those checks.

That's all Be There.js is trying to do.

Installation

Install via NPM:

npm install be-there.js

Usage

import beThere from 'be-there.js';

function functionWhoseParametersNeedTesting(p1, p2, p3, p4, p5) {
  beThere({ p1, p2, p3, p4, p5 });
}

functionWhoseParametersNeedTesting(1, null, undefined, null);

Should produce:

Error: be-there.js check failed: nulls (p2, p4) and undefined values (p3, p5) found
    at default (file:///node_modules/be-there-js/index.mjs:21:25)
