announcement

AWS has released create-aws-sdk-repro, an open-source tool that automates the generation of minimal, runnable AWS SDK for JavaScript v3 projects. This tool simplifies getting started with new services, testing SDK behavior, and troubleshooting issues by scaffolding projects with correct imports, credential handling, and error management. It supports Node.js, Browser, and React Native environments, requiring Node.js v20+ and configured AWS credentials for Node.js projects.

  • Automated AWS SDK for JavaScript v3 project generation

    The create-aws-sdk-repro tool guides users through prompts to select a service, operation, and environment (Node.js, Browser, or React Native) to generate a ready-to-run project. This includes correct SDK imports, credential configuration, and error handling, streamlining development workflows.

  • Use cases: onboarding, testing, and troubleshooting

    The tool aids developers in quickly setting up projects for new AWS services, creating isolated environments for testing specific SDK operations, and generating minimal reproducible examples for troubleshooting SDK issues by sharing clean project outputs.

  • Project generation walkthrough

    A detailed walkthrough demonstrates creating a Node.js project for the Amazon S3 ListBuckets operation in us-west-2, covering CLI commands, environment selection, service and operation choices, and reviewing the generated project structure including index.js and package.json.

  • Environment-specific setup and configuration

    For Node.js projects, default AWS credentials are used. Browser and React Native projects leverage Amazon Cognito identity pools for secure browser-safe credentials, with generated guides for setup and necessary polyfills included.

  • Clean up and cost considerations

    Generated projects are standalone and can be removed by deleting the project directory. Users are advised to clean up any created Cognito identity pools. The tool itself incurs no cost; standard AWS API pricing applies only when running the generated applications.
