Register Job Processors +The queue system supports both **long-running processes** and **serverless** deployments: -```typescript -import { register } from "@captable/queue" +### Long-Running Workers (Traditional) -// Register a simple job processor -register({ - type: "send-email", - process: async (payload: { to: string; subject: string; body: string }) => { - // Send email logic here - console.log(`Sending email to ${payload.to}`) - } -}) -``` - -### 2. Queue Jobs +Perfect for dedicated servers, containers, and traditional hosting: ```typescript -import { addJob } from "@captable/queue" +import { createWorker } from "@captable/queue"; -// Add a job to the queue -const jobId = await addJob("send-email", { - to: "user@example.com", - subject: "Welcome!", - body: "Welcome to our platform!" -}) - -// Add a delayed job (execute in 1 hour) -await addJob("send-reminder", payload, { - delay: 3600 // seconds -}) - -// Add a high-priority job -await addJob("urgent-notification", payload, { - priority: 10 -}) +// Continuous worker with persistent polling +const worker = await createWorker(config, { + autoStart: true, + instanceId: "worker-1" +}); + +// Full lifecycle management +await worker.start(); +await worker.stop(30000); // Graceful shutdown ``` -### 3. Process Jobs +**Best for:** Dedicated servers, Docker containers, high-throughput scenarios + +### Serverless Processing (Cron/Event-Driven) + +Perfect for Vercel, Netlify, Cloudflare Workers, and cron jobs: ```typescript -import { processJobs } from "@captable/queue" +import { processJobsServerless } from "@captable/queue"; -// Process up to 10 jobs -const processedCount = await processJobs(10) +// Single execution with timeout protection +const result = await processJobsServerless({ + maxJobs: 200, + maxBatches: 10, + batchSize: 20, + timeout: 25000, // 25s for Vercel limits +}); -// Set up continuous processing -setInterval(async () => { - await processJobs(5) -}, 1000) +console.log(`Processed ${result.processed} jobs in ${result.duration}ms`); ``` -## Using BaseJob Class +**Best for:** Vercel/Netlify deployments, cost optimization, cron-triggered processing -For more complex jobs, extend the `BaseJob` class: +### Cron Route Example ```typescript -import { BaseJob } from "@captable/queue" - -interface WelcomeEmailPayload { - userId: string - email: string - name: string -} +// app/api/cron/process-jobs/route.ts +import { processJobsServerless } from "@captable/queue"; -class WelcomeEmailJob extends BaseJob { - readonly type = "welcome-email" - - protected readonly options = { - maxAttempts: 5, - retryDelay: 2000, - priority: 5 +export async function GET(request: NextRequest) { + const authHeader = request.headers.get("authorization"); + if (authHeader !== `Bearer ${process.env.CRON_SECRET}`) { + return new Response("Unauthorized", { status: 401 }); } - async work(payload: WelcomeEmailPayload): Promise { - // Send welcome email - await this.sendWelcomeEmail(payload) - } + const result = await processJobsServerless({ + timeout: 25000, // Vercel timeout limit + batchSize: 20, + }); - private async sendWelcomeEmail(payload: WelcomeEmailPayload) { - // Email sending logic - console.log(`Sending welcome email to ${payload.email}`) - } + return NextResponse.json({ + success: true, + processed: result.processed, + duration: result.duration, + }); } +``` -// Register and use the job -const welcomeJob = new WelcomeEmailJob() -welcomeJob.register() +### Serverless Health Monitoring -// Emit jobs -await welcomeJob.emit({ - userId: "user-123", - email: "user@example.com", - name: "John Doe" -}) +```typescript +import { healthCheck, getQueueStatus } from "@captable/queue"; + +// Health check endpoint +export async function GET() { + const health = await healthCheck(); + return Response.json(health, { + status: health.healthy ? 200 : 503 + }); +} -// Emit delayed job -await welcomeJob.emitDelayed(payload, 300) // 5 minutes delay +// Queue status endpoint +export async function GET() { + const status = await getQueueStatus(); + return Response.json(status); +} +``` + +## ๐Ÿ“ฆ Installation -// Bulk emit -await welcomeJob.bulkEmit([payload1, payload2, payload3]) +```bash +npm install @captable/queue ``` -## Advanced Usage +## ๐Ÿ”ง Basic Usage -### Job Options +### Setting up a Job Processor ```typescript -interface JobOptions { - delay?: number // Delay in seconds before execution - maxAttempts?: number // Maximum retry attempts (default: 3) - priority?: number // Job priority (higher = processed first) - retryDelay?: number // Base retry delay in milliseconds -} +import { register, addJob } from "@captable/queue"; + +// Define your job processor +register({ + type: "send-email", + process: async (payload: { to: string; subject: string; body: string }) => { + // Your email sending logic here + await sendEmail(payload.to, payload.subject, payload.body);

``` -## Error Handling +## โš™๏ธ Configuration -The queue automatically handles retries with exponential backoff: +### Creating Custom Configuration ```typescript -// Job fails -> retry with 1x base delay -// Job fails again -> retry with 2x base delay -// Job fails again -> retry with 4x base delay -// Max attempts reached -> job marked as failed +import { createConfig, validateConfig } from "@captable/queue";

+ +// Validate configuration +validateConfig(config); ``` -## Database Schema - -The queue uses a `job_queue` table with the following structure: - -```sql -CREATE TABLE job_queue ( - id TEXT PRIMARY KEY, - type TEXT NOT NULL, - payload JSONB NOT NULL, - status TEXT DEFAULT 'pending', - priority INTEGER DEFAULT 0, - attempts INTEGER DEFAULT 0, - max_attempts INTEGER DEFAULT 3, - retry_delay INTEGER DEFAULT 1000, - scheduled_for TIMESTAMP DEFAULT NOW(), - created_at TIMESTAMP DEFAULT NOW(), - updated_at TIMESTAMP DEFAULT NOW(), - processed_at TIMESTAMP, - failed_at TIMESTAMP, - error TEXT -);
