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.
yarn add react-valida-hook
# or
npm install react-valida-hook
