• 👊 Written in JavaScript.
• 🗃 No dependencies.

📦 Installation

🏷 Usage

Let's define some validations in React components

import React, { useState } from 'react';
import { useValidate } from 'reactrix';

function Login(props) {
  const [data, setData] = useState({});
  const [msg, setValidator] = useValidate();
  
  const handleChange = (event) => {
    setData({
      ...data,
      [event.target.name]: event.target.value
    );
  }
  
  const handleSubmit = (event) => {
    event.preventDefault();
    setValidator(data, {
      email: 'required|email',
      password: 'required|string'
    }); 
   
  }
   
    
  return (
    <form>  
        <div className="container">   
          <label>Email : </label>   
          <input type="email" placeholder="Enter Email" name="email" onChange={handleChange} />  
          <label>Password : </label>   
          <input type="password" placeholder="Enter Password" name="password" onChange={handleChange} />  
          <button type="submit" onClick={handleSubmit}>Login</button>     
          Forgot <a href="#"> password? </a>   
        </div>
    </form>
  );
  
}

💅 You can use custom react component or ui library like react-bootstrap to display error messages.

Reactrix has built-in localization support for validation messages. The default language for Reactrix is en in order to set the locale you pass the locale key/code to the localize method:

const [msg, setValidator] = useValidate('fr');

🌍 Supported Locales

Reactrix support english and french languages. This is visible in the register javascript file, which can be found in the src directory. Therefore, if you want to use multiple languages, you will have to add them to the locale folder.

All the language files should return an array of keyed strings as shown below.

Step1 - Create 2 files for languages − Spanish, German. Save Arabic file at locale/de.json

{
  "messages": {
    "alpha": "{{input}} darf nur alphabetische Zeichen enthalten"
  }
}

{
  "messages": {
    "alpha": "El campo {{input}} solo debe contener letras"
  }
}

Step2 - Export spanish and German languages from src/register.js

// export all Reactrix supported locales.
export { default as de } from '../locale/german.json';
export { default as es } from '../locale/spanish.json';
