Example

import { parser } from '@aws-lambda-powertools/parser/middleware';
import middy from '@middy/core';
import { sqsEnvelope } from '@aws-lambda-powertools/parser/envelopes/sqs;'

const oderSchema = z.object({
  id: z.number(),
  description: z.string(),
  quantity: z.number(),
});

type Order = z.infer<typeof oderSchema>;

export const handler = middy(
  async (event: Order, _context: unknown): Promise<void> => {
    // event is validated as sqs message envelope
    // the body is unwrapped and parsed into object ready to use
    // you can now use event as Order in your code
  }
).use(parser({ schema: oderSchema, envelope: sqsEnvelope }));
