Adopting the Lambda Annotations Framework

1

Amazon Polly

The function I'm going to work on, called Backmask, is part of a sample serverless application used in the AMster & the Brit's Code Corner show, broadcast on AWS on Air. The application contains an API and backing Lambda function that accepts a text string message, converts it to audio using Amazon Polly, then reverses the audio and finally returns the Base64-encoded text version of the audio. You might be familiar with this idea from music, where an artist embeds reversed messages inside the main audio (or so my co-host, AM, on Code Corner tells me!). In the latest episode of Code Corner, I work through the steps of converting the function to use the new framework live. This post represents the condensed version without all the chit-chat.

AWS Lambda

If you're a .NET developer working with AWS Lambda I hope you've heard about the new Lambda Annotations Framework. It's an open-source framework for .NET-based Lambda functions which (in my opinion) simplifies your function code, reducing boilerplate. In this blog post, published with the release of the original preview, you'll find the ideas behind the framework discussed in more detail.

Amazon API Gateway

You can find the sample application in this GitHub repo. It comprises a Serverless Application Model (SAM) template, a Lambda function using .NET 6, and an API Gateway endpoint. The function runs when the endpoint receives a request. A Lambda layer carries the dependency on ffmpeg for processing of the audio created by Polly. You can also find the original Python version, used in an earlier Code Corner episode, there too.
