Trigger.dev — Background Jobs for TypeScript Apps

What it is

Trigger.dev is an open-source background job framework purpose-built for TypeScript. It lets you write long-running tasks with automatic retries, cron scheduling, and real-time observability. Unlike traditional job queues that require separate infrastructure, Trigger.dev deploys alongside your Next.js or Node.js app.

Trigger.dev is for TypeScript developers who need reliable background processing without managing Redis, Bull, or separate worker servers.

The project is actively maintained with regular releases and a growing user community. Documentation covers common use cases, and the open-source nature means you can inspect the source code, contribute fixes, and adapt the tool to your specific requirements.

How it saves time or tokens

Traditional background job setups require a message broker (Redis), a job queue library (Bull/BullMQ), worker processes, and custom monitoring. Trigger.dev replaces all of that with a single SDK. You define tasks as TypeScript functions, and Trigger.dev handles queuing, retries, concurrency limits, and execution logging. The estimated token cost for this workflow configuration is around 2,600 tokens.

How to use

1. Initialize Trigger.dev in your project with npx trigger.dev@latest init.
2. Define tasks as TypeScript functions using the Trigger.dev SDK.
3. Trigger tasks from your API routes or event handlers using the client SDK.

Example

import { task } from '@trigger.dev/sdk/v3';

export const processOrder = task({
  id: 'process-order',
  retry: { maxAttempts: 3 },
  run: async (payload: { orderId: string }) => {
    const order = await db.orders.findUnique({
      where: { id: payload.orderId }
    });
    await sendConfirmationEmail(order);
    await updateInventory(order.items);
    return { processed: true };
  },
});

// Trigger from an API route
await processOrder.trigger({ orderId: 'ord_123' });

Common pitfalls

• Task functions must be serializable. Closures over database connections or runtime state will fail on retry because the execution context is not preserved.
• Cron schedules use UTC by default. Forgetting this causes tasks to run at unexpected times in local development versus production.
• Long-running tasks without checkpointing will restart from the beginning on retry. Use Trigger.dev's built-in checkpoint API for tasks that take more than a few minutes.

Before adopting this tool, evaluate whether it fits your team's existing workflow. Read the official documentation thoroughly, and start with a small proof-of-concept rather than a full migration. Community forums, GitHub issues, and Stack Overflow are valuable resources when you encounter edge cases not covered in the documentation.
