ServiceDef

Defined in: packages/core/src/kernel/types.ts:1887

Service definition for init-managed long-running processes.

Role

Declare one inside an Extension (or via .service() on the builder) to register a supervised long-running process.

Remarks

Services are spawned by init after boot. Dependency fields drive the startup graph: requires is a hard dep (service fails if any required dep fails), wants is soft (influences order but does not fail), after/before are ordering-only. Missing restart is equivalent to { policy: 'never' }.

Example

import type { ServiceDef } from '@fishnet/core'
const cron: ServiceDef = {
  name: 'cron', bin: '/bin/cron',
  restart: { policy: 'always', backoff: 'exponential', delay: 1000 },
}
