To merge two content versions with Quill.js, you can follow these steps:

  1. Get the content from both versions and convert them into JSON format.
  2. Use the Quill Delta module to create Delta objects from the JSON content of both versions.
  3. Merge the two Delta objects using Quill's compose method. This will combine the changes from both versions into a new Delta object.
  4. Apply the merged Delta object to a new Quill instance to display the merged content.


Here is an example code snippet to demonstrate how to merge two content versions with Quill.js:

// Get the content from both versions
const contentVersion1Json = {
  ops: [
    { insert: 'Hello' },
    { insert: '
', attributes: { bold: true } },
    { insert: 'World!' },
  ]
};

const contentVersion2Json = {
  ops: [
    { insert: 'Hey' },
    { insert: '
', attributes: { italic: true } },
    { insert: 'There!' },
  ]
};

// Create Delta objects from the JSON content of both versions
const delta1 = new Quill.import('delta').create(contentVersion1Json);
const delta2 = new Quill.import('delta').create(contentVersion2Json);

// Merge the two Delta objects
const mergedDelta = delta1.compose(delta2);

// Apply the merged Delta object to a new Quill instance
const quill = new Quill('#editor', {
  theme: 'snow'
});
quill.setContents(mergedDelta);


This code snippet shows how to merge two content versions using Quill.js and display the merged content in a Quill editor instance. You can customize the content and attributes of the versions as needed and adjust the merging logic according to your requirements.
