@folijs/core

The document model and headless editing engine of Foli: document format and validation, schema, transactions, undo history and commands. No DOM: runs in the browser, Node and workers.

Early release: the API may change in any 0.x minor version (changes in CHANGELOG.md).

npm install @folijs/core

import { createDocument, createEditor, parseDocument } from "@folijs/core";

const text = JSON.stringify(createDocument()); // stand-in for a saved document
const doc = parseDocument(JSON.parse(text)); // throws FoliDocumentError on invalid input
const editor = createEditor({ document: doc });
editor.subscribe((_state, transactions) => {
  if (transactions.some((tr) => tr.docChanged)) console.log("content changed");
});
editor.select(1); // inside the first paragraph
editor.commands.toggleMark("bold"); // the next typed text is bold
editor.commands.insertText("Hello");
const saved = JSON.stringify(editor.getDocument());

To show and edit a document in the browser, use @folijs/react or @folijs/view.
