## 💡 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:

```bash

npm install deep-waters

```

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

as the following:

```js

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.

```js

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

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

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

```
