Typescript - Types for SQS messages in lambda function

I know this question is one year old already, and the solution might exist elsewhere as well, but I was able to easily type an SQS even using the unofficial @types/aws-lambda package. You can install it with npm install --save @types/aws-lambda.

Then your handler could look like the following:

import { SQSHandler, SQSEvent } from "aws-lambda";

export const handler: SQSHandler = async (event: SQSEvent) {
	const records: any[] = event.Records;
       .... // do work here
	return;
}
