Package Exports

fastify-graceful-shutdown
fastify-graceful-shutdown/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fastify-graceful-shutdown) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Register plugin

fastify.register(require('fastify-graceful-shutdown'))

Usage

  fastify.gracefulShutdown(async (signal) => {
    fastify.log.info('Received signal to shutdown: %s', signal)
    await doSomethingAsync()
  })
})

Fastify >=5

Caveats

Don't register signal handlers otherwise except with this plugin.
Can't be used with a different logger other than Pino because we use the child logger feature to encapsulate the logs.
Use fastify onClose hook to release resources in your plugin.
The process will be exited after a certain timeout (Default 10 seconds) to protect against stuck process.
