Use Case: High-volume systems, async processing, microservices.
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 |
| Webhooks | Real-time event handling |
