  [
    {:validatex, "~> 1.0.1"}
  ]
end

Usage

If you want to use this library you have to define a few functions:

1. Initialize of form state
2. Define Validators
3. Define form in template
4. Define handle_event for on_blur event
5. Define handle_event for on_change event
6. In case of related two input forms (e.g. for password (P) and confirm password (CP)) is needed also define handle_event functions for on_blur (P) and on_change (P, CP) events.
7. For form event phx_submit define handle_event function where you'll call Validation.validate_on_submit function for each field_name of your input form and then Validation.submit_if_valid.
