Gamma Performance Tuning

Overview

Optimize Gamma API integration performance for faster response times and better throughput.

Prerequisites

• Working Gamma integration
• Performance monitoring tools
• Understanding of caching concepts

Instructions

Step 1: Client Configuration Optimization

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

const gamma = new GammaClient({
  apiKey: process.env.GAMMA_API_KEY,

  // Connection optimization
  timeout: 30000,
  keepAlive: true,
  maxSockets: 10,

  // Retry configuration
  retries: 3,
  retryDelay: 1000,
  retryCondition: (err) => err.status >= 500 || err.status === 429,

  // Compression
  compression: true,
});

Step 2: Response Caching

import NodeCache from 'node-cache';

const cache = new NodeCache({
  stdTTL: 300, // 5 minutes default
  checkperiod: 60,
});

async function getCachedPresentation(id: string) {
  const cacheKey = `presentation:${id}`;

  // Check cache first
  const cached = cache.get(cacheKey);
  if (cached) {
    return cached;
  }

  // Fetch from API
  const presentation = await gamma.presentations.get(id);

  // Cache the result
  cache.set(cacheKey, presentation);

  return presentation;
}

// Cache invalidation on updates
gamma.on('presentation.updated', (event) => {
  cache.del(`presentation:${event.data.id}`);
});

Step 3: Parallel Request Optimization

// Instead of sequential requests
async function getSequential(ids: string[]) {
  const results = [];
  for (const id of ids) {
    results.push(await gamma.presentations.get(id)); // Slow!
  }
  return results;
}

// Use parallel requests with concurrency control
import pLimit from 'p-limit';

const limit = pLimit(5); // Max 5 concurrent requests

async function getParallel(ids: string[]) {
  return Promise.all(
    ids.map(id => limit(() => gamma.presentations.get(id)))
  );
}

// Batch API if available
async function getBatch(ids: string[]) {
  return gamma.presentations.getBatch(ids); // Single request for multiple items
}

Step 4: Lazy Loading and Pagination

// Pagination for large lists
async function* getAllPresentations() {
  let cursor: string | undefined;

  do {
    const page = await gamma.presentations.list({
      limit: 100,
      cursor,
    });

    for (const presentation of page.items) {
      yield presentation;
    }

    cursor = page.nextCursor;
  } while (cursor);
}

// Usage
for await (const presentation of getAllPresentations()) {
  // Process one at a time, memory efficient
}

Step 5: Request Optimization

// Only request needed fields
const presentation = await gamma.presentations.get(id, {
  fields: ['id', 'title', 'url', 'updatedAt'], // Skip large fields
});

// Avoid redundant API calls
const createOptions = {
  title: 'My Presentation',
  prompt: 'AI content',
  returnImmediately: true, // Don't wait for generation
};

const { id, statusUrl } = await gamma.presentations.create(createOptions);

// Poll status separately if needed
const status = await gamma.presentations.status(id);

Step 6: Connection Pooling

import http from 'http';
import https from 'https';

// Reuse connections
const httpAgent = new http.Agent({
  keepAlive: true,
  maxSockets: 25,
  maxFreeSockets: 10,
  timeout: 60000,
});

const httpsAgent = new https.Agent({
  keepAlive: true,
  maxSockets: 25,
  maxFreeSockets: 10,
  timeout: 60000,
});

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

Performance Metrics

Monitoring Setup

import { performance } from 'perf_hooks';

async function timedRequest<T>(name: string, fn: () => Promise<T>): Promise<T> {
  const start = performance.now();

  try {
    const result = await fn();
    const duration = performance.now() - start;

    console.log(`[PERF] ${name}: ${duration.toFixed(2)}ms`);
    metrics.recordLatency(name, duration);

    return result;
  } catch (err) {
    const duration = performance.now() - start;
    console.log(`[PERF] ${name} FAILED: ${duration.toFixed(2)}ms`);
    throw err;
  }
}

// Usage
const presentation = await timedRequest('gamma.get', () =>
  gamma.presentations.get(id)
);

Performance Targets

Operation	Target	Action if Exceeded
Simple GET	< 200ms	Check network, use caching
List (100 items)	< 500ms	Reduce page size
Create presentation	< 5s	Use async pattern
Export PDF	< 30s	Use webhook notification
