variante-alta 🏎️

Yet another invariant alternative, albeit much smaller.

What is an invariant?

An invariant function takes a value, and if the value is falsy then the invariant function will throw. If the value is truthy, then the function will not throw.

Why variante-alta?

variante-alta is an utility package that looks to replicate invariant, albeit it is much simpler and has no custom logic beyond its core. It's extremely similar to Solidity's require function and seeks to replicate its (very basic) behavior.

Installation and usage

Install with Yarn/NPM

# yarn
yarn add variante-alta

# npm
npm add variante-alta --save

Import the function into your code

import invariant from 'variante-alta'

invariant(1 === 1, 'One is not equal to one!')
