docusaurus-plugin-panzoom

This plugin adds the ability to pan and zoom images and SVG images inside of a docusaurus website. This is useful for embedding diagrams or complex mermaid.js renders around models and object schemas. The normal theme doesn't scale tremendously well in a browser so some augmentation for complex diagrams is necessary.

This implements the excellent @panzoom/panzoom plugin

Installation

npm install @r74tech/docusaurus-plugin-panzoom

// In docusaurus.config.js
// ...
plugins: ['@r74tech/docusaurus-plugin-panzoom'],
// or
plugins: [['@r74tech/docusaurus-plugin-panzoom', {} /* options */]],

Configuration

The plugin accepts the following configuration options:

// In docusaurus.config.js
// ...
themeConfig: {
  zoom: {
    // A list of selectors to look for elements to enable pan and zoom
    // Default: ['div.mermaid[data-processed="true"]', 'div.docusaurus-mermaid-container', '.drawio']
    selectors: ['div.mermaid[data-processed="true"]', '.drawio'],
    
    // Whether to wrap the panzoom items in a div with overflow:hidden
    // This constrains the pan zoom detail into the original container
    // Default: true
    wrap: true,
    
    // The amount of time to wait in MS before the plugin client module tries to look for
    // and alter pan zoom elements. Some renders take a little bit before they appear in the
    // dom to find.
    // Default: 1000
    timeout: 1000,
    
    // Add this class to any element within the Panzoom element that you want to exclude from Panzoom handling.
    // That element's children will also be excluded. e.g. links and buttons that should not propagate the click event.
    // Default: 'panzoom-exclude'
    excludeClass: 'panzoom-exclude',
    
    // You can also pass any options supported by @panzoom/panzoom
    // See: https://github.com/timmywil/panzoom for available options
  }
