In the software development process, adopting developer tools makes it easier for developers to write code, build applications, and test more efficiently. As a developer, you can use various AWS developer tools for code editing, code quality, code completion, and so on. These tools include Amazon CodeGuru for code analysis, and Amazon CodeWhisper for getting coding recommendations powered by machine learning algorithms.

In this edition of Let’s Architect!, we’ll show you some tools that every developer should consider including in their toolkit.

10 ways to build applications faster with Amazon CodeWhisperer

This blog post shares several prompts to enhance your programming experience with Amazon CodeWhisperer.

Why is this important to developers? By default, CodeWhisperer gives you code recommendations in real time — this example shows you how to make the best use of these recommendations. You’ll see the different dimensions of writing a simple application, but most importantly, you’ll learn how to resolve problems you could face in development workflows. Even if you’re just a beginner, you’ll be able to use this example to leverage AI to increase productivity.

Automate code reviews with Amazon CodeGuru Reviewer

Code quality is important in software development. It’s essential for resilient, cost-effective, and enduring software systems. It helps guarantee performance efficiency and satisfy functional requirements, but also guarantee long-term maintainability.

In this blog post, the authors talk about the advantages offered by CodeGuru automated code reviews, which allow you to proactively identify and address potential issues before they find their way into the main branches of your repository. CodeGuru not only streamlines your development pipeline, but also fortifies the integrity of your codebase, ensuring that only the highest quality code makes its way into your production environment.

Powertools for AWS Lambda (Python)

AWS provides various tools for developers. You can access the complete list here. One in particular—Lambda Power Tools—is designed to implement serverless best practices and elevate developer velocity. Powertools for AWS Lambda (Python) is a library of observability best practices and solutions to common problems like implementing idempotency or handling batch errors. It supports different languages, such as Python, Java, Typescript, and .Net and lets you choose choose your favorite(s). There is also a roadmap available, so you can see upcoming features.

Increasing development speed with CDK Watch

Developers test their code in an AWS account to see if their changes are working successfully, especially when developing new infrastructure workloads programmatically or provisioning new services. AWS Cloud Development Kit (AWS CDK) CLI has a flag called hotswap that helps to speed up your deployments. It does this by swapping specific resources, without going through the whole AWS CloudFormation process.

Not all changes can be hotswapped, though. When hotswapping isn’t possible, cdk-watch will go back to using a full CloudFormation deployment. NOTE: This command deliberately introduces drift in CloudFormation to speed up deployments. For this reason, only use it for development purposes. Never use hotswap for your production deployments!
