The Mozilla Developer Network uses a WYSIWYG editor called CKEditor. CKEditor is an open source utility which brings the power of rich text editing to the web. This document details how to update CKEditor within the MDN codebase.
To rebuild CKEditor, run this on the host system:
cd kuma/static/js/libs/ckeditor/ ./docker-build.sh # Creates a Java container, builds CKEditor docker-compose exec web make build-static
This builds CKEditor within a Docker VM, using the Java
from CKSource, then builds static resources so that the updated editor
is installed where it belongs.
To rebuild CKEditor from a
vagrant ssh shell (or locally if you have Java
cd kuma/static/js/libs/ckeditor/source/ ./build.sh
Portions of the build process will take a few minutes so don’t expect an immediate result.
To update the CKEditor version, you’ll need to edit
build.sh and change
the value of
CKEDITOR_VERSION. Updating is important to keep MDN in sync
with CKEditor’s functional and security updates.
Updating CKEditor plugins¶
Some plugins are maintained by MDN staff in the Kuma repo. Others are updated
to the tag or commit number specified in
Change to CKEditor plugins which are bundled into Kuma should be made in the directory /kuma/static/js/libs/ckeditor/source/ckeditor/plugins/.
Once you’ve made changes to a plugin, be sure to build the editor and the static resources again, as described in Building CKEditor.
