React Valida Hook

Custom hook to create validable forms using valida-js for validation

For validation rules see valida-js docs

NOTE: Is important to know, valida-js don't return error message, only the and array of error types. Maybe will need to add a proper translation for those messages. That was made on porpuse in order to move translation to other place and not inside the validation library.

npm install react-valida-hook

    event.preventDefault()
    const valid = validateForm()
    console.log(getData())
