guideCKEditor 5 DLL builds for CKEditor 5 Collaboration Features

This guide discusses using a DLL build together with CKEditor 5 Collaboration Features and is supplemental to the CKEditor 5 DLL builds guide.

Make sure to read the base guide first before proceeding.

# Anatomy of a DLL build with CKEditor 5 collaboration features

A DLL build of the editor consists of the following parts:

  • Base DLL build. It is a single JavaScript file that combines the contents of several core CKEditor 5 packages: utils, core, engine, ui, clipboard, enter, paragraph, select-all, typing, undo, upload, and widget. These packages are either the framework core, or are features used by nearly all editor installations. The build is available on NPM in ckeditor5 package.
  • Base DLL build for CKEditor 5 Collaboration Features. It is a single JavaScript file that includes all necessary files for the collaboration features packages and extends the base DLL for CKEditor 5. The build is available on NPM in ckeditor5-collaboration package.
  • DLL-compatible package builds. Every package that is not a part of the base DLL builds, is built into a DLL-compatible JavaScript file. The CKEditor 5 Collaboration Features DLL builds are available in this format as well. These DLLs are available on NPM in @ckeditor/ckeditor5-[FEATURE_NAME] packages.

In order to create an editor with collaboration features, you need to use the two base DLL builds plus a DLL-compatible package build for each plugin you would like to include.

# Integrating CKEditor 5 Collaboration Features as DLL builds

The exact way to use a DLL build will depend on your system. Presented in this guide is the simplest method that uses the <script> tags.

In order to run the editor, you need to load the necessary files (base DLL + CF base DLL + editor creator + features). These files expose their content in the CKEditor5 global, using the following format:

CKEditor5.packageName.moduleName

This guide uses the watchdog feature feature. You can also integrate the collaboration features without it, but it is strongly recommended to use the watchdog when the real-time collaboration is enabled.

Below is an example of an integration:

<div id="presence-list-container"></div>

<div class="container">
    <div id="editor"><p>Let's edit this together!</p></div>
    <div class="sidebar" id="sidebar"></div>
</div>
