<p>Job processing for AdonisJS v6 using <a href="https://bullmq.io/" target="_blank">BullMQ</a></p>
</div>

## Getting Started

This package is available in the npm registry.

```bash
pnpm install adonisjs-jobs
```

Next, configure the package by running the following command.

```bash
node ace configure adonisjs-jobs
```

## Creating Jobs

You can create a new job by running the following command.

```sh
node ace jobs:make SendEmail
```

## Listening for Jobs

First, you need to start the jobs listener, you can spawn multiple listeners to process jobs concurrently.

```sh
node ace jobs:listen  # default queue from env `REDIS_QUEUE`

node ace jobs:listen --queue=high
node ace jobs:listen --queue=high --queue=medium
node ace jobs:listen --queue=high,medium,low

node ace jobs:listen --queue=high --concurrency=3
```

## Dispatching Jobs

Dispatching jobs is as simple as importing the job class and calling

```ts
import SendEmail from 'path/to/jobs/send_email.js'

await SendEmail.dispatch({ ... })

await SendEmail.dispatch({ ... }, { // for more job options check https://docs.bullmq.io/
  attempts: 3,
  delay: 1000,
})
```

## Import Aliases (optional)

update your `package.json` and `tsconfig.json` to use import aliases

`package.json`

```json
{
  "imports": {
    "#jobs/*": "./app/jobs/*.js"
  }
}
```

`tsconfig.json`

```json
{
  "compilerOptions": {
    "paths": {
      "#jobs/*": ["./app/jobs/*.js"]
    }
  }
}
```

```ts
import SendEmail from '#jobs/send_email.js'

await SendEmail.dispatch({ ... })
```

## Jobs Dashboard

You can view the jobs dashboard by adding the following route to your `start/routes.ts` file.

```ts
import router from '@adonisjs/core/services/router'

router.jobs() // default is /jobs

// or

router.jobs('/my-jobs-dashboard')
```

`router.jobs()` returns a route group, you can add middleware to the group

```ts
router.jobs().use(
  middleware.auth({
    guards: ['basicAuth'],
  })
)
```

## Tips

### Job Completion on Kubernetes

In Kubernetes, prevent job termination by adjusting `terminationGracePeriodSeconds` (default is 30s) to allow jobs to finish gracefully.

```yaml
spec:
  containers:
    - name: listen-jobs
      image: <IMAGE>
      command: ['node']
      args: ['ace', 'jobs:listen']
terminationGracePeriodSeconds: 1800
```

## Experimental Features

### Dispatch Closure

```ts
import { dispatch } from 'adonisjs-jobs/services/main'

await dispatch(async () => {
  const { default: User } = await import('#models/user')

console.log(await User.query().count('*'))
})

await dispatch(async () => {
  const { default: mail } = await import('@adonisjs/mail/services/main')

await mail.send((message) => {
    message
      .to('doe@example.org')
      .from('info@example.org')
      .subject('Verify your email address')
      .htmlView('emails/verify_email')
  })
})
```

## Alternative Ways to Run the Job Worker

Besides using `node ace jobs:listen`, you can also manually initialize and control the job worker in your code:

```ts
import { Worker } from 'adonisjs-jobs'
import app from '@adonisjs/core/services/app'

const worker = new Worker(app, {
  queues: ['default', 'mail'],
  concurrency: 1,
})

app.terminating(async () => {
  await worker.stop()
})

await worker.start()
```
