Middy logo

SQS batch json body parsing middleware for the middy framework, the stylish Node.js middleware engine for AWS Lambda

Middleware for iterating through a SQS batch of records and parsing the string body to a JSON body.


To install this middleware you can use NPM:

npm install --save @middy/sqs-json-body-parser


  • reviver (function) (optional): A function to be passed as the reviver for JSON.parse(text[, reviver]). If safeParse is provided then reviver will be passed to it and it is up the provided safeParse function to use it or ignore it.

Sample usage

import middy from '@middy/core'
import sqsJsonBodyParser from '@middy/sqs-json-body-parser'

const baseHandler = (event, context) => {
  const { Records } = event
  return Promise.all(Records.map(async (record, index) => { /* your message processing logic */ }))

const handler = middy(baseHandler).use(sqsJsonBodyParser())
