2-2: LGTM: Clean state setup for drag-and-drop.The import of
useCallbackand the state additions are appropriate. UsinguseReffor the drag counter is the right choice—it avoids unnecessary re-renders while tracking nested drag events, which is a standard pattern for handlingdragenter/dragleavecorrectly.Also applies to: 384-385
655-705: LGTM: Robust drag-and-drop implementation.The drag event handling is well-structured:
- The counter pattern correctly handles nested
dragenter/dragleaveevents when dragging over child elements- The
hasFiles()check ensures the app doesn't interfere with other drag operations (e.g., dragging text)preventDefault()calls are correctly placed in bothdragover(required for drop to fire) anddrop(prevents browser navigation)- When multiple images are dropped, only the first is processed—this is reasonable and keeps the behavior simple
The implementation will inherit the error handling improvements from
handleImageFileonce those are added.
707-714: LGTM: Excellent refactoring.Delegating to
handleImageFileeliminates code duplication and ensures consistent behavior between drag-and-drop and file input uploads. The input value reset is a nice touch—it allows users to re-select the same file.
1050-1067: LGTM: Polished drag feedback UI.The overlay provides clear visual feedback during drag operations:
pointer-events-noneis crucial—it ensures the overlay doesn't interfere with drag events- The z-index (90) correctly positions it below the export modal but above all other content
- The instructional text accurately describes the behavior (switching to Upload mode)
- The styling is consistent with the app's design language

Add error handling for file reading and consider file size validation.
The FileReader implementation lacks error handling—if reading fails (corrupted file, memory issue, etc.), the user receives no feedback. Additionally, very large images converted to data URLs can consume significant memory, especially when stored in the history stack.
Apply this diff to add error handling:
const handleImageFile = useCallback((file: File) => {
+ if (file.size > 10 * 1024 * 1024) { // 10MB limit
+ alert('Image file is too large. Please upload an image smaller than 10MB.');
+ return;
+ }
+
const reader = new FileReader();
reader.onload = (event) => {
if (event.target?.result) {
setHistory((curr) => ({
past: [...curr.past, curr.present],
present: { ...curr.present, mode: 'image', imageSrc: event.target?.result as string },
future: []
}));
}
};
+ reader.onerror = () => {
+ alert('Failed to read image file. Please try a different image.');
+ };
reader.readAsDataURL(file);
}, []);📝 Committable suggestion

In App.tsx around lines 387 to 399, the FileReader usage lacks error handling
and no file-size validation which can lead to silent failures or OOM when large
images are converted to data URLs and pushed into history; before reading,
validate file.size (e.g., reject above a configurable threshold like 5MB) and
notify the user if too large, and replace direct data-URL storage with a safer
approach (prefer creating a blob URL via URL.createObjectURL(file) or store the
File/Blob reference instead of embedding a large base64 string) to reduce memory
usage; additionally attach reader.onerror and reader.onabort handlers to surface
errors (update component state or call an error/toast handler) and ensure any
created blob URLs are revoked when no longer needed or when popping history.
