I frequently see people looking for simple examples of how to use one of AWS' SDKs to do simple operations on DynamoDB and other services. So I thought it was about time we had a few examples to work from that weren’t completely overwhelming. In this post, I’ll show you a few ways to use the AWS SDK for JavaScript to get data out of a DynamoDB table. I hope these will serve as a decent reference for many basic operations you might need to take to read information from your DynamoDB tables!
So you’ve developed a snazzy new Serverless API on AWS and everything is going great. That is until you realize that there might eventually be production data behind it that you don’t want someone with Postman and 20 minutes on their hands to have access to. That’s where Lambda Authorizers come in. They’re a way to make sure that your API will only respond to authorized callers. Let’s look at how to implement authorizers for ourselves using an example application called Serverless Jams - where we vote on our favorite coding-related music.
I have a new three-hour long course on building serverless applications from the perspective of a frontend developer. Some of the things you’ll learn include:
The best part? It’s 100% free! Feel free to check it out here. Let me know what you think on Twitter!
During AWS re:Invent this year AWS announced a new way to make HTTP APIs with API Gateway v2. It now includes things like native support for JSON Web Tokens (JWTs) and a vastly simplified number of AWS resources to get an API up and running. You can read about all the updates here in my post on the Serverless Blog.
