Function captureLambdaHandler

A middy middleware automating capture of metadata and annotations on segments or subsegments for a Lambda Handler.

Using this middleware on your handler function will automatically:

• handle the subsegment lifecycle
• add the ColdStart annotation
• add the function response as metadata
• add the function error as metadata (if any)

Example

import { Tracer, captureLambdaHandler } from '@aws-lambda-powertools/tracer';
import middy from '@middy/core';

const tracer = new Tracer({ serviceName: 'serverlessAirline' });

const lambdaHandler = async (_event: any, _context: any) => {
  ...
};

export const handler = middy(lambdaHandler).use(captureLambdaHandler(tracer));

Returns

middleware - The middy middleware object
