Part of the MLH 2025 series. I walked through two paths for adding Template and Mention plugins to an existing CKEditor 5 project — the fast route via CKEditor builder, and the manual integration when the scenario gets messy.
Released: Tue Sep 23 2025
What this MLH 2025 session was about
I bet most of you have shipped a CKEditor integration and then been asked to add "just one more plugin" a quarter later. Templates? @mentions? Both? Suddenly you're staring at a webpack config wondering if you should rebuild from scratch. You don't have to.
Two paths I walked through
- CKEditor builder — assemble a new build with the extra plugins. Fast path, copy-paste ready.
- Manual integration — for projects that have outgrown the builder UI: importing the plugin packages, wiring the toolbar, and registering the configuration.
- Iteration discipline — clean development cycles that don't break what's already in production.
Who it was for
Developers with a working CKEditor 5 integration who need to extend it, particularly with Templates and Mention plugins. Practical, focused, no fluff — that was the whole point of the MLH 2025 series. All right, we're done!
