Lucidchart — Document & Diagram Management

Overview

Primary workflow for Lucidchart document and diagram management. Covers the complete

lifecycle: creating documents, adding shapes and connectors via Standard Import,

editing diagram content programmatically, and exporting to PNG, PDF, or SVG. Uses the

Lucid REST API v1 with OAuth 2.0 authorization. The Standard Import format (.lucid)

supports pages, shapes, lines, groups, and styling in a single declarative payload.

Instructions

Step 1: Create a Document

const doc = await client.documents.create({
  title: 'API Architecture Diagram',
  product: 'lucidchart',  // or 'lucidspark'
});
console.log(`Document: ${doc.documentId}`);
console.log(`Edit URL: ${doc.editUrl}`);

Step 2: Add Shapes and Connectors via Standard Import

const importData = {
  pages: [{
    id: 'page1',
    title: 'Main',
    shapes: [
      { id: 's1', type: 'rectangle', boundingBox: { x: 100, y: 100, w: 200, h: 80 },
        text: 'API Gateway', style: { fill: '#4A90D9' } },
      { id: 's2', type: 'rectangle', boundingBox: { x: 100, y: 300, w: 200, h: 80 },
        text: 'Database', style: { fill: '#7B68EE' } },
      { id: 's3', type: 'rectangle', boundingBox: { x: 400, y: 200, w: 200, h: 80 },
        text: 'Auth Service', style: { fill: '#50C878' } },
    ],
    lines: [
      { id: 'l1', endpoint1: { shapeId: 's1' }, endpoint2: { shapeId: 's2' },
        stroke: { color: '#333', width: 2 } },
      { id: 'l2', endpoint1: { shapeId: 's1' }, endpoint2: { shapeId: 's3' },
        stroke: { color: '#333', width: 2, pattern: 'dashed' } },
    ],
  }],
};
await client.documents.import(doc.documentId, importData);

Step 3: Edit Existing Content

const pages = await client.documents.getPages(doc.documentId);
const pageId = pages[0].id;
// Update a shape's text and style
await client.pages.updateShape(doc.documentId, pageId, 's1', {
  text: 'API Gateway v2',
  style: { fill: '#2E86C1', fontSize: 14 },
});

Step 4: Export Document

const png = await client.documents.export(doc.documentId, {
  format: 'png',   // also: 'pdf', 'svg', 'csv' (for data shapes)
  pageIndex: 0,
  scale: 2,        // retina-quality
  crop: true,       // trim whitespace
});
fs.writeFileSync('diagram.png', png);
console.log('Exported diagram.png');

Error Handling

Output

A successful run produces a Lucidchart document with shapes, connectors, and styling,

then exports a high-resolution PNG. Console output shows the document ID and edit URL.
