Gamma Core Workflow B: Editing and Export

Overview

Implement workflows for editing existing presentations and exporting to various formats.

Prerequisites

Completed gamma-core-workflow-a setup
Existing presentation to work with
Understanding of export formats

Instructions

Step 1: Retrieve and Edit Presentation

import { GammaClient } from '@gamma/sdk';

const gamma = new GammaClient({ apiKey: process.env.GAMMA_API_KEY });

async function editPresentation(presentationId: string) {
  // Retrieve existing presentation
  const presentation = await gamma.presentations.get(presentationId);

  // Update title and style
  const updated = await gamma.presentations.update(presentationId, {
    title: 'Updated: ' + presentation.title,
    style: 'modern',
  });

  return updated;
}

Step 2: Slide-Level Editing

async function editSlide(presentationId: string, slideIndex: number, content: object) {
  const presentation = await gamma.presentations.get(presentationId);

  // Update specific slide
  const updatedSlide = await gamma.slides.update(
    presentationId,
    slideIndex,
    {
      title: content.title,
      content: content.body,
      layout: content.layout || 'content',
    }
  );

  return updatedSlide;
}

async function addSlide(presentationId: string, position: number, content: object) {
  return gamma.slides.insert(presentationId, position, {
    title: content.title,
    content: content.body,
    generateImage: content.imagePrompt,
  });
}

async function deleteSlide(presentationId: string, slideIndex: number) {
  return gamma.slides.delete(presentationId, slideIndex);
}

Step 3: Export to Various Formats

type ExportFormat = 'pdf' | 'pptx' | 'png' | 'html';

async function exportPresentation(
  presentationId: string,
  format: ExportFormat,
  options: object = {}
) {
  const exportJob = await gamma.exports.create(presentationId, {
    format,
    quality: options.quality || 'high',
    includeNotes: options.includeNotes ?? true,
    ...options,
  });

  // Wait for export to complete
  const result = await gamma.exports.wait(exportJob.id, {
    timeout: 60000,
    pollInterval: 2000,
  });

  return result.downloadUrl;
}

// Usage examples
const pdfUrl = await exportPresentation('pres-123', 'pdf');
const pptxUrl = await exportPresentation('pres-123', 'pptx', { includeNotes: false });
const pngUrl = await exportPresentation('pres-123', 'png', { slideIndex: 0 }); // First slide only

Step 4: Asset Management

async function uploadAsset(presentationId: string, filePath: string) {
  const fileBuffer = await fs.readFile(filePath);

  const asset = await gamma.assets.upload(presentationId, {
    file: fileBuffer,
    filename: path.basename(filePath),
    type: 'image',
  });

  return asset.url;
}

async function listAssets(presentationId: string) {
  return gamma.assets.list(presentationId);
}

Output

Updated presentation with modifications
Exported files in various formats
Managed presentation assets
Download URLs for exports

Error Handling

Error	Cause	Solution
Export Timeout	Large presentation	Increase timeout or reduce slides
Format Not Supported	Invalid export format	Check supported formats
Asset Too Large	File exceeds limit	Compress or resize image
Slide Not Found	Invalid index	Verify slide exists
