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:
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.
