A DatoCMS plugin that automatically shows a character counter on fields that are configured to have validations on length.

• Automatic activation: The plugin automatically attaches to fields with length validators
• Manual installation: Can also be manually added to fields
• Multiple field types: Supports string, text, and structured_text field types
• Smart counting: For structured text, counts only the actual text content (not markup)

• Single-line string
• Multiple-paragraph text
• Structured text

The plugin uses the overrideFieldExtensions hook to automatically add a character counter addon to fields that:

1. Are one of the supported field types (string, text, or structured_text)
2. Have length validation configured
3. Don't already have the character counter addon installed

The counter displays the current character count in a small, unobtrusive format below the field.

Based on the official DatoCMS character-counter plugin.
