# Scheduled Jobs

In this chapter, you’ll learn about scheduled jobs and how to use them.

## What is a Scheduled Job?

When building your commerce application, you may need to automate tasks and run them repeatedly at a specific schedule. For example, you need to automatically sync products to a third-party service once a day.

In other commerce platforms, this feature isn't natively supported. Instead, you have to setup a separate application to execute cron jobs, which adds complexity as to how you expose this task to be executed in a cron job, or how you debug it when it's not running within the platform's tooling.

Medusa removes this overhead by supporting this feature natively with scheduled jobs. A scheduled job is an asynchronous function that the Medusa application runs at the interval you specify during the Medusa application's runtime. Your efforts are only spent on implementing the functionality performed by the job, such as syncing products to an ERP.

- You want the action to execute at a specified schedule while the Medusa application **isn't** running. Instead, create a [custom CLI script](../custom-cli-scripts/page.mdx) and execute it using the operating system's equivalent of a cron job.
- You want to execute the action once when the application loads. Use [loaders](../modules/loaders/page.mdx) or [custom CLI scripts](../custom-cli-scripts/page.mdx#run-custom-script-on-application-startup) instead.
- You want to execute the action if an event occurs. Use [subscribers](../events-and-subscribers/page.mdx) instead.

## How to Create a Scheduled Job?

You create a scheduled job in a TypeScript or JavaScript file under the `src/jobs` directory. The file exports the asynchronous function to run, and the configurations indicating the schedule to run the function.

For example, create the file `src/jobs/hello-world.ts` with the following content:

![Example of scheduled job file in the application's directory structure](https://res.cloudinary.com/dza7lstvk/image/upload/v1732866423/Medusa%20Book/scheduled-job-dir-overview_ediqgm.jpg)

```ts title="src/jobs/hello-world.ts"
import { MedusaContainer } from "@medusajs/framework/types"
import {
  ContainerRegistrationKeys,
} from "@medusajs/framework/utils"

export default async function greetingJob(container: MedusaContainer) {
  const logger = container.resolve(
    ContainerRegistrationKeys.LOGGER
  )

  logger.info("Greeting!")
}

export const config = {
  name: "greeting-every-minute",
  schedule: "* * * * *",
}
```

You export an asynchronous function that receives the [Medusa container](../medusa-container/page.mdx) as a parameter. In the function, you resolve the [Logger utility](../../debugging-and-testing/logging/page.mdx) from the Medusa container and log a message.

You also export a `config` object that has the following properties:

- `name`: A unique name for the job.
- `schedule`: A string that holds a [cron expression](https://crontab.guru/) indicating the schedule to run the job.

This scheduled job executes every minute and logs into the terminal the message `Greeting!`.

### Test the Scheduled Job

To test out your scheduled job, start the Medusa application:

```bash
npm run dev
```

After a minute, the following message will be logged to the terminal:

```bash
info:    Greeting!
```

### Disable a Scheduled Job

Do not disable a scheduled job by commenting out or removing the `config` export while keeping the file in `src/jobs/`. This will cause errors when you build or start your Medusa application.

To disable a scheduled job, move its file out of the `src/jobs` directory. For example, move it to `src/scripts/` or any directory other than `src/jobs/`.

### Troubleshooting Scheduled Jobs

If your scheduled job is not running at the expected times, refer to the [Scheduled Job Troubleshooting Guide](https://docs.medusajs.com/resources/troubleshooting/scheduled-job-not-running).

***

## Example: Sync Products Once a Day

In a realistic scenario like syncing products to an ERP once a day, you should create a [workflow](../workflows/page.mdx) and execute it in a scheduled job.

A workflow is a task made up of a series of steps, and you construct it like you would a regular function, but it's a special function that supports rollback mechanism in case of errors, background execution, and more.

You can learn how to create a workflow in the [Workflows](../workflows/page.mdx) chapter, but this example assumes you already have a `syncProductToErpWorkflow` implemented. To execute this workflow once a day, create a scheduled job at `src/jobs/sync-products.ts` with the following content:

```ts title="src/jobs/sync-products.ts"
import { MedusaContainer } from "@medusajs/framework/types"
import { syncProductToErpWorkflow } from "../workflows/sync-products-to-erp"

export default async function syncProductsJob(container: MedusaContainer) {
  await syncProductToErpWorkflow(container)
    .run()
}

export const config = {
  name: "sync-products-job",
  schedule: "0 0 * * *",
}
```

In the scheduled job function, you execute the `syncProductToErpWorkflow` by invoking it and passing it the container, then invoking the `run` method. You also specify in the exported configurations the schedule `0 0 * * *` which indicates midnight time of every day.

The next time you start the Medusa application, it will run this job every day at midnight.

***

## Check the Scheduled Time of a Job

Medusa runs scheduled jobs at the pattern you specify in the `schedule` property of the job's configurations. During a run, you can check the exact date and time the job was scheduled to run at using the `context` parameter of the scheduled job function.

The `context` parameter is available since Medusa [v2.17.0](https://github.com/medusajs/medusa/releases/tag/v2.17.0).

For example:

```ts title="src/jobs/hello-world.ts"
import { MedusaContainer } from "@medusajs/framework/types"
import { ScheduledJobContext } from "@medusajs/framework"
import {
  ContainerRegistrationKeys,
} from "@medusajs/framework/utils"

export default async function greetingJob(
  container: MedusaContainer,
  context: ScheduledJobContext
) {
  const logger = container.resolve(
    ContainerRegistrationKeys.LOGGER
  )

  logger.info(`Greeting! Scheduled for: ${context.scheduledFor}`)
}

export const config = {
  name: "greeting-every-minute",
  schedule: "* * * * *",
}
```

The `context` parameter is an object that has the following property:

- `scheduledFor`: A `Date` object indicating the exact date and time the job was scheduled to run at.
