workflows	Create async background tasks (workflows) using SQS or Hatchet. Use when building queue jobs, background processing, or async tasks.

Overview

Workflows are async tasks processed by background workers. Two runners:

Runner	Use Case	Features
SQS	Simple fire-and-forget tasks	Fast, no dependencies, max 15min delay
Hatchet	Complex workflows needing retries, multi-step, or long delays	Typed outputs, configurable timeouts, observability

Quick Start

1. Add Job Name

// server/src/queue/JobName.ts
export enum JobName {
  // ... existing
  MyNewWorkflow = "my-new-workflow",
}

2. Define Payload & Register

// server/src/queue/workflows.ts

// Add payload type
export type MyNewWorkflowPayload = {
  orgId: string;
  env: AppEnv;
  customerId: string;
  // ... your fields
};

// Add to registry
const workflowRegistry = {
  // ... existing
  myNewWorkflow: {
    jobName: JobName.MyNewWorkflow,
    runner: "sqs",  // or "hatchet"
  } as WorkflowConfig<MyNewWorkflowPayload>,
};

// Add trigger function
export const workflows = {
  // ... existing
  triggerMyNewWorkflow: (payload: MyNewWorkflowPayload, options?: TriggerOptions) =>
    triggerWorkflow({ name: "myNewWorkflow", payload, options }),
};

3. Create Handler

For SQS: See references/SQS.md

For Hatchet: See references/HATCHET.md

4. Trigger from Code

import { workflows } from "@/queue/workflows.js";

await workflows.triggerMyNewWorkflow({
  orgId: ctx.org.id,
  env: ctx.env,
  customerId,
});

// With delay
await workflows.triggerMyNewWorkflow(payload, { delayMs: 5000 });

Required Payload Fields

All workflows must include:

{
  orgId: string;
  env: AppEnv;
  customerId?: string;  // optional but common
}
