`typescript
// jobs.ts
import { createJob } from "@prohst-tech/nest-pg-boss"

interface IFoobarJobData {
foo: string
bar: boolean
}

const FoobarJob = createJob("foobar")
`

#### Create new Jobs

`typescript
// module.ts
import { PGBossModule } from "@prohst-tech/nest-pg-boss";
import { FoobarService } from "./service.ts";

@Module({
imports: PGBossModule.forJobs([FoobarJob]),
providers: [FoobarService]
})
class FoobarModule {}

`

`typescript
// service.ts
import { JobService } from "@prohst-tech/nest-pg-boss";
import { FoobarJob, IFoobarJobData } from "./jobs.ts";

@Injectable()
class FoobarService {
constructor(
@FoobarJob.Inject()
private readonly foobarJobService: JobService,
) {}

async sendJob() {
await this.foobarJobService.send({ foo: "oof", bar: true });
}
}
`

#### Process Jobs

Jobs can be processed by using the @FoobarJob.Handle() decorator.

`typescript
// service.ts
@Injectable()
class FoobarService {
/ ... /

@FoobarJob.Handle()
async handleJob(job: Job) {
// do something
}
}
`

You can optionally pass an object with WorkOptions to .Handle():

`typescript
@FoobarJob.Handle({ teamSize: 10, teamConcurrency: 2 })
`
