Env-var Boolean (elean)

Convenience function to parse environment variables to boolean (perfect companion for dotenv).

require('dotenv').config();

import elean from '@simplyhexagonal/elean';

const { MY_ENV_VAR } = process.env;

elean(MY_ENV_VAR); // returns either true or false

Tested evaluations

elean('') // false
elean(0) // false
elean('0') // false
elean(null) // false
elean('null') // false
elean('NULL') // false
elean(false) // false
elean('false') // false
elean('FALSE') // false
elean(undefined) // false
elean('undefined') // false

// ---

elean(1) // true
elean('1') // true
elean('xyz') // true
elean(true) // true
elean('true') // true
elean('TRUE') // true
