Ten Examples of Getting Data from DynamoDB with Python and Boto3

I recently wrote about using Node.js and the AWS SDK for JavaScript to get data from DynamoDB. In this post, I’ll take you through how to do the same thing with Python and Boto3! We’ll use both a DynamoDB client and a DynamoDB table resource in order to do many of the same read operations on the DynamoDB table. I hope this helps serve as a reference for you whenever you need to query DynamoDB with Python.

Eight Examples of Fetching Data from DynamoDB with Node.js

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!

Adding Lambda Authorizers to your Serverless Applications

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.
