Editor#

The editor is a Milkdown v7 WYSIWYG interface loaded inside the native GUI window. All content API calls go through the app:// scheme handler (in-process, no HTTP server — see GUI).

Milkdown#

Milkdown (v7, 11k+ stars) is the core editor. It’s built on ProseMirror + Remark and works with markdown natively — no HTML→MD→HTML roundtrip. Both WYSIWYG and raw markdown source modes are available via toggle.

inb4doc’s plugin surface is intentionally small, but Milkdown and ProseMirror have a large plugin ecosystem — individual maintainers or forks can implement custom behavior through ProseMirror plugins or Milkdown prosemirror plugins.

Hotwired (Turbo + Stimulus)#

Navigation and interaction use Hotwired:

Turbo Drive — SPA-like navigation without client-side routing
Turbo Frames — Inline editing without hand-coded fetch calls
Stimulus — Tiny controllers for editor mount/unmount, mode toggle, save buffer, flush

Combined bundle: ~28KB gzip.

Flush-Based Writes#

Edits accumulate in an in-memory buffer + IndexedDB (crash recovery). The filesystem is only touched on explicit “Flush” or page navigation. This prevents partial writes and reduces I/O.

Supported Formatting#

The editor supports full CommonMark and GitHub Flavored Markdown (GFM), including tables, strikethrough, task lists, and auto-links.

Triggered by typing / or via the + button in the toolbar.
