tiny-invariant 1.0.6

Tiny-invariant is a npm package that is a miniature, lightweight, and streamlined alternative to the invariant function. An invariant function tests a value, throwing if the tested value is falsy, while not throwing if the value is truthy. Whether you're looking to perform basic truthy-falsy tests, or want to handle error messaging on failed condition checks in JavaScript, the Tiny-invariant package might be a great fit for you.

Tiny-invariant package can be used by installing it using npm or yarn. Once installed, it can be imported and used in your code. For instance, you could use it to test truthy or falsy values:

import invariant from 'tiny-invariant';

invariant(truthyValue, 'This should not throw!');

invariant(falsyValue, 'This will throw!');
// Error('Invariant violation: This will throw!');

You can also make use of a function to generate custom error messages on invariant failures:

import invariant from 'tiny-invariant';

invariant(value, () => getExpensiveMessage());

Installation can be done as follows using npm or yarn:

# yarn
yarn add tiny-invariant

# npm
npm install tiny-invariant --save

The tiny-invariant documentation can be found on the GitHub repository for the package at https://github.com/alexreardon/tiny-invariant. This documentation will provide you with detailed information on usage instructions, package API, installation guidelines, and other pertinent information for successfully implementing the tiny-invariant within your JavaScript projects.
