variableChecker

Simple helper to do variable checks and keep complexity low.

How to use it

Samples

const variableChecker = require('variablechecker');

(async () => {
  try {
    const a = 1;
    await variableChecker.checkAsync(a, 'a'); // This will success
    
    const b = undefined;
    await variableChecker.checkAsync(b, 'b'); // This will fail and rejects an error message
    
    const c = 0;
    const condition = (x) => x >= 0;
    await variableChecker.checkAsync(c, 'c', { condition }); // This will success
    
    const c = -1;
    const condition = (x) => x >= 0;
    await variableChecker.checkAsync(c, 'c', { condition }); // This will fail and rejects an error message
    
    console.log('DONE');
  } catch (err) {
    console.log(err);
  }
})();

Update & Migration

0.1.1 => 1.0.0

The variableChecker now ships as object containing a method called checkAsync. If you're using v0.1.1, then you change all existing calls from await variableChecker(...); to await variableChecker.checkAsync(...);.
