What it does:

• Adds lambda "event" object to phat event
• Adds lambda "context" object to phat event
• Emits the log event on failure, or success
• Binds the error to the logEvent on failure
• Binds phatEvent instance to context, for re-use throughout the lambda

Get Started

const middy = require('middy')
const phatEventMiddleware = require('phat-event-middy-lambda-middleware');
const { logger } = require('./utils/logger')

const originalHandler = async function (event, _, callback) {
  callback(null, true)
}

const handler = middy(originalHandler).use(phatEventMiddleware({ log: logger }))

module.exports = { handler }

{
  event: ...,
  context: ...,
  success: true
}

The resultant phat event is:

{
  event: ...,
  context: ...,
