Key Findings

Architecture & Design

The PR introduces direct state mutations on node objects, which bypasses Vue's reactivity system. This pattern could lead to inconsistent state management. Consider using proper reactive stores or event-driven communication instead.

Security Considerations

The addition of crossOrigin = 'anonymous' enables cross-origin access to images. While likely necessary for canvas operations, ensure this doesn't expose sensitive images to unauthorized access.

Performance Impact

The synchronous Promise.all for image loading could block the UI thread, especially with large images or slow networks. Consider asynchronous loading patterns or loading indicators.

Integration Points

The changes improve vueNodes integration with the mask editor by properly setting up node state and synchronizing with the node output store. However, removed safety checks could introduce runtime errors.

Positive Observations

• Good use of TypeScript with proper type annotations
• Proper async/await pattern for the mask editor function
• Icon updates follow the project's icon naming conventions (i-lucide:* format)
• Added proper fallback logic for vueNodes mode

Next Steps

1. Address the high-priority logic issue in app.ts to prevent potential null reference errors
2. Consider architectural feedback for proper state management patterns
3. Add error handling for image loading operations
4. Consider performance optimizations for image loading
5. Validate CORS security implications

This is a comprehensive automated review. For architectural decisions requiring human judgment, please request additional manual review.

So the fundamental issue is that, when in Litegraph, both LoadImage and SaveImage have their imgs property assigned when their preview/output is udpated. For SaveImage it is set via this code

And useNodeImage is invoked in the draw loop here

But for LoadImage, I guess it is set in the useNodeImageUpload widget logic (which Vue nodes don't have). So, in Vue mode, only the SaveImage is getting node.imgs set. Then, the solution in this PR involves getting the image, initializing the Image object, then setting it manually.

A few questions:

1. Should this logic go into its own function? Being a side-effect of handleEditMask is fairly confusing and I don't think future maintainers will understand the logic and what is happening
2. Do we need to create a new Image object? Aren't we doubling the work? Can we not just do this:

<template>
  <img
    v-for="(url, i) in imageUrls"
    :key="i"
    :src="url"
    ref="imageEls"
    class="..."
  />
</template>

<script setup lang="ts">
const imageEls = ref<HTMLImageElement[]>([])

const handleEditMask = async () => {
  if (!props.nodeId) return
  const node = app.rootGraph?.getNodeById(props.nodeId)
  if (!node) return

  node.imageIndex = currentIndex.value
  node.imgs = imageEls.value          // ← already HTMLImageElements
  app.canvas?.selectNode(node)
  await commandStore.execute('Comfy.MaskEditor.OpenMaskEditor')
}
</script>

LGTM!
