Migration from TinyMCE

From some point, TinyMCE changed its license from MIT to GPL. Editor42 is built from the latest MIT-licensed state of TinyMCE, so you get a maintained, secure rich text editor under a permissive license without rewriting your integration.

You can migrate from any version of TinyMCE — the process is the same regardless of which release you are currently on, and in most cases the switch is seamless.

Step by Step​

Self-Hosted​

Replace the TinyMCE directory with the Editor42 distribution and update your script tag:

- <script src="/js/tinymce/tinymce.min.js"></script>
+ <script src="/js/editor42/editor42.min.js"></script>

CDN​

Update the CDN URL:

- <script src="https://cdn.tiny.cloud/1/KEY/tinymce/6/tinymce.min.js"></script>
+ <script src="https://cdn.editor42.com/editor42/latest/editor42.min.js"></script>

Init Call​

- tinymce.init({
+ editor42.init({
    selector: '#my-editor'
  });

The old tinymce.init() call will also work — Editor42 sets window.tinymce as an alias for compatibility.

API Compatibility​

TinyMCE APIs, events, configuration options, and plugins work with Editor42. Both window.editor42 and window.tinymce are available by default, so existing code that references window.tinymce will continue to work as-is.

If you want to disable the window.tinymce alias — reducing compatibility but getting rid of that TinyMCE-branded global — set EDITOR42_NO_SHIM before loading Editor42:

<script>window.EDITOR42_NO_SHIM = true;</script>

Technical Details​

Editor42 rebrands the editor's identifiers — CSS classes, global variables, hooks, and MIME types — and reports itself as version 42 through majorVersion, while keeping the TinyMCE 6 API unchanged. For the complete list of renamed identifiers and the versioning scheme, see Technical Details & Compatibility.
