import { useValidationStore } from "@naukri-ui-dev/react-validator";

const Form = () => {
    const {
       errors,                //object to read errors
       setFieldValue          //function to set validator state
    } = useValidationStore();
    
    const onUsernameChange = (val: string) => {
        //set the local state
        ...
        //set the validator state
        setFieldValue("username", val);
    }
    
    const onPasswordChange = (value: string) => {
        //set the local state
        ...
        //set the validator state
        setFieldValue("password", value);
    }
    
    return (
        <form>
            <div>
                <input
                    onChange={(e) => onUsernameChange(e.target.value)} 
                    placeholder="Username"
                />
                {errors.username && (<div className="err-msg">{errors.username}</div>)}
            </div>
            <div>
                 <input
