T-Validator

Wrapper over validator.js library that provides you easy way to use it with Typescript classes.

Usage

Create your class and put some validation annotations on its properties you want to validate:

import {Contains, IsInt, IsLength, IsEmail, IsFQDN, IsDate} from "t-validator/ValidationAnnotations";

export class Post {

    @IsLength(10, 20)
    title: string;

    @Contains('hello')
    text: string;

    @IsInt({ min: 0, max: 10 })
    rating: number;

    @IsEmail()
    email: string;

    @IsFQDN()
    site: string;

    @IsDate()
    createDate: Date;

}

let validator = new Validator();

let post = new Post();
post.title = 'Hello'; // should not pass
post.text = 'this is a great post about hell world'; // should not pass
post.rating = 11; // should not pass
post.email = 'google.com'; // should not pass
post.site = 'googlecom'; // should not pass

console.log(validator.validate(Post, post)); // returns you array of errors for fields that didn't pass validation

Validator also supports validation groups. Take a look on samples in ./sample for more examples of usages.
