Bumps @aws-lambda-powertools/parameters from 2.32.0 to 2.33.0.

Release notes

Sourced from @aws-lambda-powertools/parameters's releases.

v2.33.0

Summary

In this release, the HTTP event handler gains a new metrics middleware that lets you emit per-request latency, fault, and error metrics with a single line of configuration. The middleware automatically uses the matched route as a dimension and attaches request metadata like HTTP method, path, status code, and API Gateway request IDs.

We've also improved the parser package by exporting InferOutput from the public types entry point, resolving a TypeScript declaration emit error (TS2883) that affected consumers using safeParse mode — particularly those upgrading to TypeScript 6.

⭐ Congratulations to @yashar-new10 and @faberchri for their first PR merged in the project 🎉

Metrics Middleware

You can now use the Metrics utility with the HTTP event handler to automatically emit CloudWatch metrics for every request. The middleware:

Adds the matched route as a metric dimension (e.g., GET /users/:id)

Emits latency (Milliseconds), fault (Count), and error (Count) metrics

Attaches request metadata including httpMethod, path, statusCode, userAgent, and ipAddress

Adds API Gateway-specific metadata (apiGwRequestId, apiGwApiId) when available

Uses NOT_FOUND as the route dimension when no route matches, preventing dimension explosion
import { Router } from '@aws-lambda-powertools/event-handler/http';
import { metrics as metricsMiddleware } from '@aws-lambda-powertools/event-handler/http/middleware/metrics';
import { Metrics } from '@aws-lambda-powertools/metrics;
import type { Context } from 'aws-lambda';
const metrics = new Metrics({ namespace: 'my-app', serviceName: 'my-service' });
const app = new Router();
app.use(metricsMiddleware(metrics));
app.get('/users/:id', async ({ params }) => {
return { id: params.id, name: 'Jane' };
});
export const handler = async (event: unknown, context: Context) =>
app.resolve(event, context);
