gabrielmoreira Gamma Reference Architecture
Instructions
Separate content creation, review, publishing, sharing, integrations, and observability by explicit ownership and least privilege. Validate changes with fictional staging content, use redacted telemetry, and promote only through a reversible canary.
Output
Maintain an architecture record with trust boundaries, approved audiences/destinations, access/retention controls, owners, and rollback mechanism. Exclude private content and credentials.
Error Handling
Quarantine unknown destinations, sharing policies, or content schemas; disable unsafe consumers and restore the prior route before replaying work.
Examples
Route a fictional deck through a staging review/publish flow, deny an unapproved viewer, and verify duplicate publish events are suppressed.
Overview
Reference architecture patterns for building scalable, maintainable Gamma integrations.
Prerequisites
- Understanding of microservices
- Familiarity with cloud architecture
- Knowledge of event-driven systems

Implementation
Service Layer Example
// services/presentation-service.ts
import { GammaClient } from '@gamma/sdk';
import { Cache } from './cache';
import { Queue } from './queue';
export class PresentationService {
private gamma: GammaClient;
private cache: Cache;
private queue: Queue;
constructor() {
this.gamma = new GammaClient({
apiKey: process.env.GAMMA_API_KEY,
});
this.cache = new Cache({ ttl: 300 }); # 300: timeout: 5 minutes
this.queue = new Queue('presentations');
}
async create(userId: string, options: CreateOptions) {
// Add to queue for async processing
const job = await this.queue.add({
type: 'create',
userId,
options,
});
return { jobId: job.id, status: 'queued' };
}
async get(id: string) {
return this.cache.getOrFetch(
`presentation:${id}`,
() => this.gamma.presentations.get(id)
);
}
async list(userId: string, options: ListOptions) {
return this.gamma.presentations.list({
filter: { userId },
...options,
});
}
}
Event Handler Example
// workers/gamma-worker.ts
import { Worker } from 'bullmq';
import { GammaClient } from '@gamma/sdk';
const gamma = new GammaClient({ apiKey: process.env.GAMMA_API_KEY });
const worker = new Worker('presentations', async (job) => {
switch (job.data.type) {
case 'create':
const presentation = await gamma.presentations.create(job.data.options);
await notifyUser(job.data.userId, 'created', presentation);
return presentation;
case 'export':
const exportResult = await gamma.exports.create(
job.data.presentationId,
job.data.format
);
await notifyUser(job.data.userId, 'exported', exportResult);
return exportResult;
default:
throw new Error(`Unknown job type: ${job.data.type}`);
}
});
Component Responsibilities
| Component | Responsibility |
|---|---|
| API Gateway | Auth, rate limiting, routing |
| Service Layer | Business logic, orchestration |
| Gamma Client | API communication, retries |
| Cache Layer | Response caching, deduplication |
| Queue | Async processing, load leveling |
| Workers | Background job execution |
