# rescript-validator

A composable data-validation library for ReScript. Currently under construction.

The goal of this library is to allow users to intuitively compose a set of validators using boolean logic. For example:

```rescript

let isValidUserName = {

  open Validator.StringValidators;

  open Validator.Infix;

  let isValidNonEmailHandle =

    isLongerThan(3)

    && isShorterThan(65)

    && allCharsAreAscii

    && blacklistChars(bannedChars)

    && blacklistWords(bannedWords);

  

  let isValidNonEmailHandle = useName("isValidNonEmailHandle", isValidNonEmailHandle);

  useName("isValidUserName", isEmail || isValidNonEmailHandle);

}

let userName = "qF5wr*ywDLYta40^Dbwv";

let result = Validator.validate(isValidUserName, userName);

```

This ability to compose validators will hopefully make data validation feel intuitive and easy. Feel free to take a look and offer suggestions during development.
