@wkovacs64/booleanize

A small utility to coerce a value to its boolean equivalent.

Installation

npm install @wkovacs64/booleanize

Usage

The primary purpose of this package is to deal with environment variables received as strings. For example, SOME_CONDITIONAL=false will be truthy if you just pass it to the Boolean constructor as it comes through as a non-empty string. Instead, pass it to booleanize and you will get the value back that I expect. Please note that it may not be the value YOU expect, but I created this primarily for myself. 🙂

Basically, the following strings are considered falsy:

• 'null'
• 'undefined'
• 'false'
• 'no'
• '0'

Example

# .env
SOME_CONDITIONAL=false

import { booleanize } from '@wkovacs64/booleanize';

Boolean(process.env.SOME_CONDITIONAL); // true 😕
booleanize(process.env.SOME_CONDITIONAL); // false 😊
