Beschreibung

What docs changes are you proposing?

Source: https://github.com/localstack-samples/sample-lambda-s3-image-resizer-hot-reload

Problem

Currently linked repo only.

Proposal

  • Add tutorial page with:
    • Introduction (upload image to S3, Lambda resizes, hot reload support)
    • Prerequisites (LocalStack Pro, Node.js/Python runtime, Docker)
    • Architecture diagram (S3 input → Lambda → S3 output)
    • Steps (clone repo, deploy, upload sample image, edit code for hot reload)
    • Testing the application (download resized image, verify dimensions, re-upload after code change and confirm new size)
    • Conclusion (serverless image pipeline patterns)

Acceptance Criteria

  • Doc page structured like other tutorials with explicit Testing the application steps.

Code of Conduct

  • I agree to follow this project's Code of Conduct
