💡 What is Deep Waters?

An easy-to-compose functional validation system for javascript developers

It allows to easily create custom and reusable validators from the pre-existing ones by using a functional approach and the composition principle.

📖 Documentation

☕️ Features

• Full functional
• Strict types validation based on Object.prototype.toString instead of typeof to avoid unexpected behaviours
• Tiny and lightweight
• Extremely modular
• Concise API

🕺 Installation

You can install it by using NPM:

npm install deep-waters

Deep Waters exports its modules as CommonJS modules, so that each one can be easily imported individually, as the following:

const compose = require('deep-waters/compose');
const minLength = require('deep-waters/minLength');
const ofUniqueItems = require('deep-waters/ofUniqueItems'); 

const arrayValidator = compose(minLength(3), ofUniqueItems);  

arrayValidator([1,2,3,4]); // => true;

Alternatively, it's possible to import all the modules at once with the same result.

const DW = require('deep-waters');

const arrayValidator = DW.compose(DW.minLength(3), DW.ofUniqueItems);  

arrayValidator([1,2,3,4]); // => true;
