chore(deps): bump @aws-lambda-powertools/logger from 2.25.2 to 2.27.0

[dependabot]

Bumps @aws-lambda-powertools/logger from 2.25.2 to 2.27.0.

Release notes

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

v2.27.0

Summary

We're excited to announce an update to our Event Handler utility, featuring new middleware for CORS (Cross-Origin Resource Sharing) configuration and automatic response compression. We have also added support for Route Prefixes which allows you to avoid repeating a shared prefix in each route definition.

We've listened to your feedback and also made some slight changes to the type signature in the handlers to improve developer experience.

We have also made the Error handlers more versatile by allowing a Response object or a JavaScript object to be returned from the error handler.

⭐ Congratulations @​guillemcomerma for their first PR merged in the project 🎉

CORS Middleware

Docs

The CORS middleware ensures CORS headers are returned as part of the response when your functions match the path invoked and the Origin matches one of the allowed values.

import { Router } from '@aws-lambda-powertools/event-handler/experimental-rest';
import { cors } from '@aws-lambda-powertools/event-handler/experimental-rest/middleware';
import type { Context } from 'aws-lambda';
const app = new Router();
app.use(
cors({
origin: 'https://example.com',
maxAge: 300,
})
);
app.get('/todos/:todoId', async ({ params: { todoId } }) => {
const todo = await getTodoById(todoId);
return { todo };
});
export const handler = async (event: unknown, context: Context) =>
app.resolve(event, context);
/**
When invoked from a valid origin, this returns:
{
"statusCode": 200,
"headers": {
"access-control-allow-credentials": "false",
"access-control-allow-origin": "https://example.com",
"content-type": "application/json"
},
"multiValueHeaders": {
</tr></table>
