Logs the incoming request (input) and the response (output).

By default, the logging operate by using the console.log function. You can pass as a parameter a custom logger with additional logic if you need. It can be useful if you want to process the log by doing a http call or anything else.


To install this middleware you can use NPM:

npm install --save @middy/input-output-logger


Sample usage

import middy from '@middy/core'
import inputOutputLogger from '@middy/input-output-logger'

const handler = middy((event, context) => {
  const response = {
    statusCode: 200,
    headers: {},
    body: JSON.stringify({ message: 'hello world' })
  return response
