Request

No parameters required. This is a simple GET request.

Response

array

string

The complete URL to access the image, including the SAS token for authentication.Format: https://{accountName}.blob.core.windows.net/images/{blobName}?{sasToken}

string

The blob name in the format {prompt}_{timestamp}.png

Behavior

Connects to Azure Blob Storage using shared key credentials
Lists all blobs in the “images” container
Generates a fresh SAS token for secure access
Constructs full URLs with SAS tokens for each image
Sorts images by timestamp in descending order (newest first)
Returns the sorted list as JSON

Example request

const response = await fetch('/api/getImages', {
  method: 'GET'
});

const data = await response.json();
console.log(data.imageUrls);
// [
//   {
//     url: "https://account.blob.core.windows.net/images/mountain_1234567890.png?sv=2021...",
//     name: "mountain_1234567890.png"
//   },
//   {
//     url: "https://account.blob.core.windows.net/images/ocean_1234567880.png?sv=2021...",
//     name: "ocean_1234567880.png"
//   }
// ]

Implementation details

The function extracts timestamps from filenames using this parsing logic:

const sortedImageUrls = imageUrls.sort((a, b) => {
  const aName = a.name.split("_").pop().toString().split(".").shift();
  const bName = b.name.split("_").pop().toString().split(".").shift();
  return bName - aName; 
})

This ensures images are displayed in reverse chronological order, with the most recently generated images appearing first.
