Error Handling in AWS Lambda With Wrappers

We have been using web frameworks to develop web applications since long before serverless came around, and middlewares are stable in these web frameworks. Express.js, for instance, lets you create middlewares at several stages of the request handling pipeline, and even ships with a few common middlewares out of the box.

As our code moves into Lambda functions and we move away from these web frameworks, are middlewares still relevant? If so, how might they look in this new world of serverless?

In this post, we’ll revisit the idea of middlewares, their role in application development with AWS Lambda, and how we can use middlewares to enforce consistent error handling across all of our Lambda functions.
