CommentsRepository (comments/comments)

@ckeditor/ckeditor5-comments/src/comments/commentsrepository

class

Stores the list of CommentThread and provides event-driven API for managing them. It is also responsible for using the comments adapter to communicate with the data source.

CommentsRepository is a context plugin. It can be added to a context or to an editor. Add it to the context configuration if you use Context in your integration.

The event-driven API makes it possible to attach a listener to each action that changes comment data. Using different event priorities allows to attach an action before the main action ('low' priority) or after the main action ('high' priority). It works very similar to decorate.

Sample usage:

// Get the comments repository:
const commentsRepository = editor.plugins.get( 'CommentsRepository' );

// Create a new, empty comment thread on a DOM form field element:
commentsRepository.openNewCommentThread( { channelId, target: formFieldElement } );

// Get all comment threads:
commentsRepository.getCommentThreads();

// Set the adapter:
commentsRepository.adapter = {
	// ...
};

For more information about the comments adapter see CommentsAdapter.

Methods

  • constructor()

  • addCommentThread( commentThreadData, [ data.channelId ], data.threadId, [ data.comments ], [ data.target ], [ data.isFromAdapter ] ) → CommentThread

    Adds a new comment thread.

    When a target is provided, the comment annotation will be attached to this target.

    Use this method to load the comments data during the editor initialization if you do not use the adapter integration.

    Note: This method fires the event-addCommentThread event and the default behavior is added as a 'normal' priority listener. It makes it possible to cancel the method or call some custom code before or after the default behavior is executed.

    Note: The comments adapter will send the data only if commentThreadData.comments is not empty and commentThreadData.isFromAdapter is set to false.

    See also CommentsRepository#openNewCommentThread().

    An example of loading a comment thread on editor initialization:

    commentsRepository.addCommentThread( {
        threadId: 'thread-id',
        channelId: 'channel-id',
        comments: [
            {
                commentId: 'comment-1',      // String
                authorId: 'author-id',       // String
                content: 'First comment',    // String
                createdAt: new Date( ... )   // Date instance
            },
            // ...
        ],
        target: () => ...,
        // Added during initialization, so do not call the adapter:
        isFromAdapter: true
    } );

    Parameters

    [ data.isFromAdapter ] : Boolean

    A flag describing whether the added data comes from an adapter (true) or is a new data (false). If set to true, the comment data will be added only in the editor and will not be sent to the adapter.

    The added comment thread.

    Fires

  • fetchCommentThread( data = { data.channelId, data.threadId } ) → Promise.<CommentThread>

    Gets the comment thread data using the adapter and adds the thread to the editor.

    Returns a list of comment threads added to the repository.

    You can provide a set of filtering options to narrow down the results set.

    Parameters

    Return only comment threads added to a given channel.

    [ options.skipNotAttached ] : Boolean

    Parameters

    threadId : String

    Returns

    Boolean
  • isReadOnly( channelId ) → Boolean

    Returns true if a given channel is set to read-only mode, returns false otherwise.

    Parameters

    Boolean
  • openNewCommentThread( commentThreadData = { [commentThreadData.channelId], [commentThreadData.threadId], commentThreadData.target } ) → CommentThread | null

    Creates a new, empty comment thread.

    Displays a new comment annotation attached to the target and focuses the comment editor. When the comment data is submitted, the comment thread is added to the editor and sent to the adapter.

    The ID of the comment thread. Random id will be generated if it is not set. All thread IDs should be unique.

    commentThreadData.target : HTMLElement | Rect | function

    The target that the comment balloon should be attached to. If a function is passed, it should return a DOM element or Rect.

    Returns

    CommentThread | null

    The created comment thread or null if there was a problem creating the thread (for example, if the comments repository was in the read-only mode).

    Fires

  • setActiveCommentThread( threadId )

    Marks a comment thread with the given ID as active. When threadId is null, the currently active comment thread will be deactivated.

    Parameters

    threadId : String | null
  • switchReadOnly( value, [ channelId ] )

    Changes the read-only state for comment threads.

    When the value is true then all comment threads will be switched to read-only, when the value is false then all comment threads will be switched to editing mode.

    Optionally new state can be applied to a comment threads limited to a given channel.
