createError

The `createError` function helps in creating HTTP errors with a specified status code and message. This is useful for handling errors in a standardized way in your Lambda functions.

const { createError } = require('@middy/util');

const error = createError(400, 'Bad Request');
console.log(error);

jsonSafeParse

The `jsonSafeParse` function safely parses a JSON string into an object. If the string is not valid JSON, it returns `null` instead of throwing an error.

const { jsonSafeParse } = require('@middy/util');

const jsonString = '{"key": "value"}';
const parsedObject = jsonSafeParse(jsonString);
console.log(parsedObject);

normalizeHttpResponse

The `normalizeHttpResponse` function ensures that the HTTP response object conforms to the expected format, making it easier to handle responses in a consistent manner.

const { normalizeHttpResponse } = require('@middy/util');

const response = { statusCode: 200, body: 'Success' };
const normalizedResponse = normalizeHttpResponse(response);
console.log(normalizedResponse);
