@middy/http-json-body-parser

What is @middy/http-json-body-parser?

@middy/http-json-body-parser is a middleware for AWS Lambda functions that automatically parses JSON-encoded request bodies. It simplifies the process of handling JSON input in serverless applications by converting the body of incoming HTTP requests into a JavaScript object.

What are @middy/http-json-body-parser's main functionalities?

Automatic JSON Parsing

This feature automatically parses the JSON body of incoming HTTP requests and makes it available as a JavaScript object in `event.body`. This eliminates the need to manually parse the JSON string in each handler.

const middy = require('@middy/core');
const jsonBodyParser = require('@middy/http-json-body-parser');

const handler = middy((event, context) => {
  // event.body is now a parsed JSON object
  return {
    statusCode: 200,
    body: JSON.stringify({ message: 'Parsed body', data: event.body })
  };
});

handler.use(jsonBodyParser());

module.exports = { handler };
