Part of the MLH 2025 series. I took a CKEditor 5 vanilla JavaScript starter all the way to a real TypeScript GitHub repo — types, tooling, and a build setup another developer can clone and run.

What this MLH 2025 session was about
Having written a good share of JavaScript code, I wanted to expand a CKEditor 5 starter into something I'd actually merge into production. That meant moving off the vanilla JS demo and into a TypeScript GitHub repo with types, lint, and a clean build pipeline.
The journey
- Starting point — the CKEditor 5 vanilla JS starter.
- Migrating to TypeScript — tsconfig, type imports for CKEditor 5 packages, and the small gotchas in between.
- Setting up the GitHub repo — scripts, CI-friendly structure, and a setup another developer can clone and run.
- Where the type definitions actually pay off (and where they're just compile-time noise).
Who it was for
Developers comfortable with JS but new to TypeScript, especially those starting from the CKEditor 5 starter and ready to graduate to a real repo. Yippee — what a fun one to put together.
