@templatical/core

Framework-agnostic editor logic — state, history, auto-save. The reactive engine behind @templatical/editor.

Powers @templatical/editor. Use this package directly if you want to build a custom UI on top of the Templatical state model — for example, a CLI tool, automation pipeline, or your own visual editor.

Built on @vue/reactivity (no full Vue runtime), so it works anywhere reactive primitives do.

Install

npm install @templatical/core @templatical/types

Usage

import { useEditor } from '@templatical/core';
import { createDefaultTemplateContent, createTitleBlock } from '@templatical/types';
import { watch } from '@vue/reactivity';

const editor = useEditor({
  content: createDefaultTemplateContent(),
});

// Mutate state — these methods live on the editor return value
editor.addBlock(createTitleBlock({ text: 'Welcome!' }));
editor.selectBlock(editor.content.value.blocks[0].id);

// Read reactive state
console.log(editor.content.value);          // current TemplateContent
console.log(editor.selectedBlock.value);    // currently selected Block | null
console.log(editor.state.isDirty);          // dirty flag

// React to changes
watch(editor.content, (next) => {
  console.log('Template updated', next);
});

Exports

• useEditor — reactive state (content, selection, viewport, darkMode, isDirty) + mutation methods (addBlock, removeBlock, moveBlock, updateBlock, updateSettings, selectBlock, …)
• useHistory — undo/redo stack
• useHistoryInterceptor — wraps mutation methods so they push onto the history stack automatically
• useBlockActions — higher-level helpers built on top of useEditor (createAndAddBlock(type), duplicateBlock, deleteBlock, updateBlockProperty)
• useAutoSave — debounced save with onSave callback
• useConditionPreview — display condition preview state
• useDataSourceFetch — fetch helper for custom block data sources

Cloud subpath

The @templatical/core/cloud subpath provides Templatical Cloud integrations (Auth, API client, WebSocket, AI chat/rewrite, collaboration, comments, scoring). Used by @templatical/editor's initCloud(). See Cloud docs.
