Quick Tip: Generate Presigned URLs with AWS Amplify Storage 🌱

Here's a quick tip I've been meaning to share about generating presigned URLs with AWS Amplify Storage Gen 2. This is particularly useful when you need to provide temporary access to files stored in your S3 bucket.

import { getUrl } from 'aws-amplify/storage'

// Generate a presigned URL that expires in 5 minutes
const result = await getUrl({
  key: 'path/to/your/file.pdf',
  options: {
    expiresIn: 300, // 5 minutes in seconds
  },
})

const presignedUrl = result.url

Why This Matters

  • Security: Instead of making files public, you can generate temporary access URLs
  • Control: Set custom expiration times for access
  • Simplicity: Much easier than manually configuring AWS SDK

Potential Future Explorations

  • Implementing automatic URL refresh mechanisms
  • Handling different content types
  • Batch URL generation strategies

Note: This is a growing idea that I might expand into a full article with more implementation details and use cases. Feel free to experiment with this pattern and let me know your thoughts!
