Valilang

========

Create validation rules in a single format, meant to be used in both client and server sides.

The problem

-----------

In web applications and websites, form validation is boring since (if you want to have neat web forms) you have to do it twice: On the server side, and on the client side, in Javascript. To make matters worse, you often find yourself repeating code time and time again.

The solution

------------

Valilang is based upon JSON (for portability), and using it you will be able to define a set of validation rules for each of your form fields.

```html

    {

        "fields": ["name",  "email", "recipients"],

        "fieldValidation": {

            "name": [

                "required",

                "min-10",

                "max-50",

                "split",

                "listmax-2"

            ],

            "email": [

                "required",

                "min-3",

                "max-60",

                "email"

            ],

            "recipients": [

                "required",

                "split-,; ",

                "listmin-1",

                "email"

            ]

        }

    }

```

By creating a validation rules file and then including it from your page using a script tag, along with valilang.js, you have the client side covered. By default, valilang binds event handlers to `keyup`, for better responsiveness, however you will be able to change this.

Developers will be able to create new rules (and only create client and serverside code for those rules), but a lot of predefined rules will be set in place.

Current state

-------------

Valilang is still under development. The format is not well defined, and server side libraries for several languages are not in place yet. However, I could certainly use some help. If you are interested in helping, fork and pull request!

If you want to create a port of valilang to a certain framework or language, create a github repository, and open an issue in the [valilang tracker][issues_url].
