v2.24.0

Summary

We’ve listened to your feedback and starting from this release of Parser we support only Zod v4 for all our built-in schemas and envelopes. Additionally the utility got a power up and it now supports schemas written using Standard Schema 🔥.

We’ve also fixed a bug in Tracer that prevented requests made via proxies to be traced correctly and another bug in Metrics that caused dimension sets to be added correctly to the metrics data object..

🌟 Congratulations to @​chetan9518, @​sdangol, and @​matteofigus for their first PRs merged in the project 🎉

Using Parser with Standard Schema

Docs

You can now use schemas written using Valibot or other Standard Schema-compatible parsing library to parse incoming events using the parser Middy.js middleware or TypeScript class method decorator. This is useful if your codebase is already relying on one of these libraries or you want to have full control over the bundle size.

Note that our built-in schemas and envelopes are still defined only using Zod. If you would like us to support other libraries like Valibot please open an issue and we will consider it based on the community's feedback.

If you are using Zod v3 and need more time to migrate, you can continue using Parser v2.23.0 as long as needed.

import { Logger } from '@aws-lambda-powertools/logger';
import { parser } from '@aws-lambda-powertools/parser/middleware';
import middy from '@middy/core';
import {
  array,
  number,
  object,
  optional,
  pipe,
  string,
  toMinValue,
} from 'valibot';
const logger = new Logger();
const orderSchema = object({

id: pipe(number(), toMinValue(0)),

description: string(),

items: array(

object({

id: pipe(number(), toMinValue(0)),

quantity: pipe(number(), toMinValue(1)),

description: string(),

})

),

optionalField: optional(string()),

});
export const handler = middy()

.use(parser({ schema: orderSchema }))
