You can read the documentation at: https://middy.js.org/docs/middlewares/do-not-wait-for-empty-event-loop

This middleware sets context.callbackWaitsForEmptyEventLoop property to false. This will prevent Lambda from timing out because of open database connections, etc.

Install

To install this middleware you can use NPM:

npm install --save @middy/do-not-wait-for-empty-event-loop

Options

By default the middleware sets the callbackWaitsForEmptyEventLoop property to false only in the before phase, meaning you can override it in handler to true if needed. You can set it in all steps with the options:

  • runOnBefore (boolean) (default true) - sets property before running your handler
  • runOnAfter (boolean) (default false)
  • runOnError (boolean) (default false)

Sample usage

import middy from '@middy/core'
import doNotWaitForEmptyEventLoop from '@middy/do-not-wait-for-empty-event-loop'

const handler = middy((event, context) => {
  return {}
})

handler.use(doNotWaitForEmptyEventLoop({runOnError: true}))

// When Lambda runs the handler it gets context with callbackWaitsForEmptyEventLoop property set to false

handler(event, context, (_, response) => {
  t.is(context.callbackWaitsForEmptyEventLoop,false)
})
