be-there v1.1.0

be-there

A Javascript presence assertion library

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

That's all be-there wants to do.

Installation

Install via NPM:

npm install be-there

Usage

const beThere = require('be-there');

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

functionWhoseParametersNeedTesting(1, null, undefined, null);

Should produce:

Error: be-there check failed: nulls (p2, p4) and undefined values (p3, p5) found
    at _default (/node_modules/be-there/lib/be-there.js:30:25)
    at functionWhoseParametersNeedTesting (repl:2:3)
