Walkthrough

The bulk download API handler was updated to integrate watermarking functionality. It now retrieves and processes watermark-related fields, determines if files require watermarking, and includes watermark configuration and viewer metadata in the payload sent to the Lambda ZIP creation function. The folder structure and file selection logic were also adjusted to support these enhancements.

Changes

File(s) Change Summary
pages/api/links/download/bulk.ts Enhanced bulk download API to support watermarking: selects watermark fields, updates file structure, and includes watermark config and viewer metadata in Lambda payload.

253-270: Use optional chaining for cleaner code.

The file key selection logic is correct, but the conditional check can be simplified.

Apply this diff to use optional chaining:

-        folderDocs &&
-          folderDocs.forEach((doc) => {
+        folderDocs?.forEach((doc) => {
🧰 Tools
🪛 Biome (1.9.4)

[error] 253-270: Change to an optional chain.

Unsafe fix: Change to an optional chain.

(lint/complexity/useOptionalChain)


291-303: Consider using consistent date/time formatting.

The watermark configuration looks good, but the date/time formatting may vary across different server locales.

Consider using ISO format or specifying a locale for consistent date/time representation:

-                  date: new Date(view.viewedAt).toLocaleDateString(),
-                  time: new Date(view.viewedAt).toLocaleTimeString(),
+                  date: new Date(view.viewedAt).toLocaleDateString('en-US'),
+                  time: new Date(view.viewedAt).toLocaleTimeString('en-US'),

Or use ISO format:

-                  date: new Date(view.viewedAt).toLocaleDateString(),
-                  time: new Date(view.viewedAt).toLocaleTimeString(),
+                  date: new Date(view.viewedAt).toISOString().split('T')[0],
+                  time: new Date(view.viewedAt).toISOString().split('T')[1].split('.')[0],

8-8: LGTM!

The import for the IP address utility is necessary for capturing viewer metadata in watermarks.


33-33: LGTM!

The additional fields in the Prisma query are essential for watermarking functionality - viewer identification, watermark configuration, and document metadata.

Also applies to: 39-41, 69-69


157-163: LGTM!

The extended type definition properly supports watermarking metadata while maintaining backward compatibility with optional properties.


180-181: LGTM!

The function signature extension and watermarking logic correctly identify files that need watermarking (PDFs and images) when the feature is enabled.

Also applies to: 209-219


228-242: LGTM!

The file key selection logic correctly uses the processed file for watermarked PDFs and falls back appropriately for other cases.
