confere.js

confere.js is a simple promise based javascript validation library heavily inspired by the laravel validation!

Installation

Download or clone the repo add lib/confere.js to your html script

Usage

var confere = new Confrere({
    rules: {
        name: 'required|min:3|max:254',
        email: 'required|email|max:254',
        birth_date: 'required|date|date_before:2004-01-01' //ex: under 13 not allowed
    }
});

confere.validate ({
    name: "Jhon Doe",
    email: "myemail@gmail.com",
    birth_date: "1992-05-12",
}).then (function () {
    //the data is valid, do some stuff ex: submiting the data    
}).catch(function (result) {
    //the data is invalid, show error messages, you can use the result.fields to retrive all validation errors errors    
});

With Forms

Html:

<form>
    <input type="text" name="name" data-rule="required|min:3"><br/>
    <input type="text" name="surname" data-rule="required|min:3"><br/>
    <input type="text" name="birth_date" data-rule="required|date|date_before:2004-01-01">
</form>

var confere = new Confere({
    rules: document.forms[0]
})
document.forms[0].addEventListener('submit', function (e) {
        e.preventDefault();
        confere.validate().then(function () {
            //the data is valid, do some stuff ex: submiting the data
        }).catch(function (err) {
            //the data is invalid, show error messages, you can use the result.fields to retrive all validation errors errors
        })
    });

The code above will produce the same output as the previous, but row there is no need for complicated configuration because we are using htm attributes the stuff that we all knows!
