@pagent-libs/docs-core

Core document editor engine for pagent-docs. Zero React dependencies.

Features

• Document model with blocks (paragraphs, headings, lists, tables, images)
• ProseMirror schema and state management
• Text and paragraph style pooling for memory efficiency
• Event system with batching
• Undo/redo history
• TypeScript strict mode

Usage

import { DocumentImpl, type Block } from '@pagent-libs/docs-core';

const doc = new DocumentImpl('doc_1', 'My Document');

// Get sections and blocks
const sections = doc.getSections();
const blocks = sections[0].blocks;

// Update page config
doc.setSectionPageConfig(sections[0].id, {
  size: { w: 816, h: 1056 },
  margins: { top: 96, right: 96, bottom: 96, left: 96, header: 48, footer: 48 },
  orientation: 'portrait',
});

// Serialize/deserialize
const data = doc.getData();
doc.setData(data);

Block Types

• paragraph - Basic text paragraph
• heading - Heading levels 1-6
• list-item - Bulleted or numbered list items
• table - Tables with rows and cells
• image - Images with optional captions

ProseMirror Integration

The package includes ProseMirror schema and utilities for rich text editing:

import { 
  docsSchema, 
  createPlugins, 
  blocksToPmDoc, 
  proseMirrorToDocument 
} from '@pagent-libs/docs-core';

// Convert blocks to ProseMirror document
const pmDoc = blocksToPmDoc(blocks, schema);

// Convert ProseMirror document back to blocks
const docModel = proseMirrorToDocument(pmNode, existingDoc);

Limitations

• No collaborative editing support
• Single-section documents (multi-section support is in the data model but not implemented in the UI)
• No comments or suggestions
