prosemirror/prosemirror-transform

prosemirror‑transform is a core library of the ProseMirror rich‑text editing framework that implements document transformation operations (e.g., insert, delete, replace) so that edits can be treated as first‑class, shareable objects for collaborative editing and schema‑aware content manipulation. It’s intended for developers building custom, schema‑driven editors or collaborative editing experiences using ProseMirror.
