draftjs_exporter's Introduction

Draft.js Exporter

Draft.js is a framework for building rich text editors. However, it does not support exporting documents at HTML. This gem is designed to take the raw ContentState (output of convertToRaw) from Draft.js and convert it to HTML using Ruby.

Usage

# Create configuration for entities and styles
config = {
  entity_decorators: {
    'LINK' => DraftjsExporter::Entities::Link.new(className: 'link')
  },
  block_map: {
    'header-one' => { element: 'h1' },
    'unordered-list-item' => {
      element: 'li',
      wrapper: ['ul', { className: 'public-DraftStyleDefault-ul' }]
    },
    'unstyled' => { element: 'div' }
  },
  style_map: {
    'ITALIC' => { fontStyle: 'italic' }
  }
}

# New up the exporter
exporter = DraftjsExporter::HTML.new(config)

# Provide raw content state
exporter.call({
  entityMap: {
    '0' => {
      type: 'LINK',
      mutability: 'MUTABLE',
      data: {
        url: 'http://example.com'
      }
    }
  },
  blocks: [
    {
      key: '5s7g9',
      text: 'Header',
      type: 'header-one',
      depth: 0,
      inlineStyleRanges: [],
      entityRanges: []
    },
    {
      key: 'dem5p',
      text: 'some paragraph text',
      type: 'unstyled',
      depth: 0,
      inlineStyleRanges: [
        {
          offset: 0,
          length: 4,
          style: 'ITALIC'
        }
      ],
      entityRanges: [
        {
          offset: 5,
          length: 9,
          key: 0
        }
      ]
    }
  ]
})
# => "<h1>Header</h1><div>\n<span style=\"font-style: italic;\">some</span> <a href=\"http://example.com\" class=\"link\">paragraph</a> text</div>"
