AWS launches LocalStack integration in VS Code IDE to simplify local testing for serverless applications

AWS launches LocalStack integration in Visual Studio Code (VS Code), enabling developers to easily test and debug serverless applications in their local IDE. With this new integration, developers can use LocalStack to locally emulate and test their serverless applications using familiar VS Code interface without switching between tools or managing complex setup, thus simplifying their local serverless development process.

LocalStack, an AWS Partner Network (APN) partner, enables developers to emulate AWS services such as AWS Lambda, Amazon SQS, Amazon API Gateway, and DynamoDB for local application development and testing. Previously, to use LocalStack to emulate AWS services in VS Code, developers had to manually configure ports, make code changes, and switch context between the IDE and LocalStack interface. Now, with LocalStack integration in VS Code, developers can connect to LocalStack environment from their IDE without manual configuration or code changes. This gives developers access to emulated AWS resources in the IDE, making it easy to build and test serverless applications locally. For example, they can now easily test and debug Lambda functions and their interactions with AWS services in a LocalStack emulated environment from their IDE.

This integration is now available to developers using the AWS Toolkit for VS Code (v3.74.0 or later). There is no additional cost from AWS for using this integration. To get started, follow the guided AWS Walkthrough in VS Code, which automatically installs the LocalStack CLI, guides through LocalStack account setup, and creates a LocalStack profile. Then, switch to LocalStack profile and deploy applications directly to the LocalStack environment. To learn more, visit the AWS News Blog, AWS Toolkit documentation, and the Lambda Developer Guide.
