dont working onClose hooks

[productdevbook]

import fp from 'fastify-plugin'
import Redis from 'ioredis'
import waitOn from 'wait-on'
import { database } from '../config'

declare module 'fastify' {
  interface FastifyInstance {
    redis: Redis
  }
}

export const redisPlugin = fp(async (f) => {
  const logger = f.log.child({ plugin: 'redis' })

  logger.info('Wait for redis connection.')
  // wait for db to be alive
  await waitOn({
    resources: [`tcp:${database.redisHOST}:${database.redisPORT}`],
    timeout: 30000,
  })

  logger.info('redis is started. Connecting to it.')

  const redis = new Redis(database.redisURL)

  f.decorate('redis', redis)

  f.addHook('onClose', async () => {
    redis.disconnect()
  })
})

There is no onClose-Hook.

What is not working?

[productdevbook]

When I ctrl + c from the terminal, the stop event doesn't work. Normally, I need to reset the database, I have db settings, it doesn't do it either. Close does not work in any of my plugins.

onClose event into hooks is called when fastify.close() is executed. I suggest using something like this:

'use strict'

const fastify = require('fastify')({ logger: { level: 'trace' } })

fastify
  .listen({ port: 3000 }, err => {
    if (err) throw err
  })

fastify.addHook('onClose', async () => {
  console.log('message from onClose')
})

const signals = ['SIGTERM', 'SIGINT']

signals.forEach(signal => {
  process.once(signal, async () => {
    await fastify.close()
  })
})

Thank you,

this working now

const signals = ['SIGTERM', 'SIGINT']

signals.forEach((signal) => {
  process.on(signal, async () => {
    await fastify.close()
  })
})

Maybe ctrl+c does not send SIGTERM or SIGKILL?
