In @src/composables/usePaste.test.ts:
- Around line 70-86: Tests use loose casting (mockCanvas as any, mockNode as
unknown as LGraphNode); import and use real LiteGraph types to strengthen
typing: import LGraphCanvas and LGraphNode from the litegraph module, declare
mockCanvas as Partial<LGraphCanvas> with required fields (graph.add,
graph.change, graph_mouse, etc.) and declare mockNode as Partial<LGraphNode> or
cast only after constructing a proper shape, then call pasteImageNode(mockCanvas
as LGraphCanvas, dataTransfer.items) and adjust expectations accordingly to
remove broad any casts.
- Line 165: Replace fragile next-tick waits implemented as "await new
Promise(resolve => setTimeout(resolve, 0))" in the usePaste.test.ts tests with a
deterministic Vitest utility: either wrap the subsequent assertions in await
vi.waitFor(() => { ... }) or enable fake timers and call
vi.advanceTimersByTime(0) before asserting; ensure you import vi from 'vitest'
and update the three occurrences (the current short timeouts used to let event
handlers run) so tests become timing-deterministic and less fragile.
In @src/composables/usePaste.ts:
- Line 114: The call uses a type assertion on the Ref ("canvas as LGraphCanvas")
even though the store provides a type-safe accessor; replace that assertion by
calling the store getter so the call becomes
pasteImageNode(canvasStore.getCanvas(), items, imageNode) — update the
invocation of pasteImageNode to use canvasStore.getCanvas() instead of the
asserted canvas variable and remove the unnecessary type assertion.
- Around line 51-69: pasteImageNode currently ignores the failure case when
LiteGraph.createNode('LoadImage') returns null, leading to a silent no-op;
update pasteImageNode to detect when newNode is null or graph?.add(newNode)
results in null and call useToastStore().addAlert(...) with a clear error
message (consistent with useLoad3dDrag.ts patterns) before returning so the user
is notified, and ensure you still call graph?.change() only when a node is
actually added and that pasteItemsOnNode(items, imageNode, 'image') is not
invoked with a null imageNode.
In @src/scripts/app.ts:
- Line 1443: Remove the stray debug statement console.log('DROPPED!') from
src/scripts/app.ts by deleting that line (or replace it with a proper logger
call if intentional), ensuring no leftover console.debug/console.log calls
remain in the surrounding function/context that would emit debug output in
production.

Learning: In the ComfyUI_frontend project, Zod is on v3.x. Do not suggest Zod v4 standalone validators (z.uuid, z.ulid, z.cuid2, z.nanoid) until an upgrade to Zod 4 is performed. When reviewing TypeScript files (e.g., src/platform/remote/comfyui/jobs/jobTypes.ts) validate against Zod 3 capabilities and avoid introducing v4-specific features; flag any proposal to upgrade or incorporate v4-only validators and propose staying with compatible 3.x patterns.

Learning: In the ComfyUI_frontend repository, lint rules require keeping 'import type' statements separate from non-type imports, even if importing from the same module. Do not suggest consolidating them into a single import statement. Ensure type imports remain on their own line (import type { ... } from 'module') and regular imports stay on separate lines.

Learning: Prefer pure function declarations over function expressions (e.g., use function foo() { ... } instead of const foo = () => { ... }) for pure functions in the repository. Function declarations are more functional-leaning, offer better hoisting clarity, and can improve readability and tooling consistency. Apply this guideline across TypeScript files in Comfy-Org/ComfyUI_frontend, including story and UI component code, except where a function expression is semantically required (e.g., callbacks, higher-order functions with closures).

Learning: When accessing reactive properties from Pinia stores in TypeScript files, avoid using .value on direct property access (e.g., useStore().isOverlayExpanded). Pinia auto-wraps refs when accessed directly, returning the primitive value. The .value accessor is only needed when destructuring store properties or when using storeToRefs().

Learning: In TypeScript test files (e.g., any test under src), avoid duplicating interface/type definitions. Import real type definitions from the component modules under test and reference them directly, so there is a single source of truth and to prevent type drift. This improves maintainability and consistency across tests.

Timestamp: 2025-12-30T01:31:04.927Z
Learning: In Vitest v4, when mocking functions that may be called as constructors (using new), the mock implementation must use function() or class syntax rather than an arrow function. Arrow mocks can cause '<anonymous> is not a constructor' errors. This is a breaking change from Vitest v3 where mocks could use an arrow function. Apply this guideline to test files that mock constructor-like calls (e.g., in tests under tests-ui, such as ComboWidget.test.ts) and ensure mock implementations are defined with function() { ... } or class { ... } to preserve constructor behavior.

29-49: LGTM! Clean extraction of paste logic.The helper function properly filters items by content type and delegates to the node's paste methods. The dual invocation of both
pasteFile(first item) andpasteFiles(all items) matches the existing behavior pattern for media nodes.
104-106: Good use of const for immutability.Changing from
lettoconstcorrectly reflects thatimageNodeis assigned once and never reassigned.src/scripts/app.ts (1)
1446-1451: LGTM! Graceful fallback for non-workflow images.The implementation correctly handles the case where a dragged image doesn't contain workflow metadata by creating a LoadImage node via
pasteImageNode. The DataTransfer wrapper is necessary to match the expected API signature.src/composables/usePaste.test.ts (3)
1-62: LGTM! Well-structured test setup.The mock configuration properly isolates the unit under test with appropriate stubs for all dependencies. The use of
vi.mockfollows Vitest best practices.
64-141: Excellent coverage for pasteImageNode.The test suite comprehensively covers:
- Creating new nodes when none provided
- Reusing existing nodes
- Handling multiple files
- Filtering by content type
- No-op behavior for empty inputs
143-277: Comprehensive behavioral coverage for usePaste composable.The tests validate all critical paste scenarios including media files, workflow JSON, keyboard modifiers, node selection context, text inputs, and clipboard metadata. This aligns with the guideline to aim for behavioral coverage of critical and new features.

In @src/composables/usePaste.test.ts:
- Around line 261-276: The test's metadata encoding is more complex than needed
for ASCII data: either simplify the encoded value in the 'should handle
clipboard items with metadata' test by replacing the TextEncoder/reduce sequence
with const encoded = btoa(JSON.stringify(data)) (and keep the rest of the test
intact: usePaste(), DataTransfer, ClipboardEvent and the expect against
mockCanvas._deserializeItems), or if UTF‑8 is required keep the current
TextEncoder approach but add a short comment above the encoded declaration
explaining that TextEncoder+reduce is used to preserve UTF‑8 characters; this
makes the intent clear and improves maintainability.
- Around line 64-141: Replace the five "as any" assertions by creating properly
typed minimal mocks: define mockCanvas as Partial<LGraphCanvas> with graph:
Partial<LGraph> (providing add and change fns), graph_mouse, current_node,
pasteFromClipboard/_deserializeItems, then cast mockCanvas to LGraphCanvas when
calling pasteImageNode; likewise define mockNode as Partial<LGraphNode> with
pasteFile and pasteFiles and cast to LGraphNode for calls. Update tests to
import the LGraphCanvas/LGraphNode types and use these Partial-based mocks
instead of using "as any".
- Around line 243-259: The test calls usePaste() but contains no assertions;
modify the test to spy/mock the canvas.pasteFromClipboard method and assert it
was called when a text input paste event is dispatched: create a jest.spyOn or
sinon stub for canvas.pasteFromClipboard before dispatching the ClipboardEvent,
dispatch the event as already done, then add an expect(spy).toHaveBeenCalled()
(and optionally expect(spy).toHaveBeenCalledWith(event.clipboardData) or the
string 'test') and finally restore the spy/stub to clean up after the test;
reference usePaste and canvas.pasteFromClipboard to locate where to add the spy
and assertions.

Learning: In TypeScript test files (e.g., any test under src), avoid duplicating interface/type definitions. Import real type definitions from the component modules under test and reference them directly, so there is a single source of truth and to prevent type drift. This improves maintainability and consistency across tests.

Learning: Prefer pure function declarations over function expressions (e.g., use function foo() { ... } instead of const foo = () => { ... }) for pure functions in the repository. Function declarations are more functional-leaning, offer better hoisting clarity, and can improve readability and tooling consistency.

Learning: In Vitest v4, when mocking functions that may be called as constructors (using new), the mock implementation must use function() or class syntax rather than an arrow function. Arrow mocks can cause '<anonymous> is not a constructor' errors. This is a breaking change from Vitest v3 where mocks could use an arrow function. Apply this guideline to test files that mock constructor-like calls (e.g., in tests under tests-ui, such as ComboWidget.test.ts) and ensure mock implementations are defined with function() { ... } or class { ... } to preserve constructor behavior.

- Line 2: The import mixes a type and a value; change the single line importing
"type LGraphNode, LiteGraph" into two imports: use an "import type { LGraphNode
} ..." solely for the type and a separate "import { LiteGraph } ..." for the
runtime value so the linter rule is satisfied and types stay erased at compile
time.
- Around line 7-16: The mockCanvas is untyped which forces `as any` everywhere;
replace it with a properly typed test factory that returns an LGraphCanvas (e.g.
createMockCanvas(overrides?: Partial<LGraphCanvas>): LGraphCanvas) that supplies
defaults for current_node, graph (with add/change as vi.fn()), graph_mouse,
pasteFromClipboard and _deserializeItems and merges any overrides; then update
test usages of mockCanvas to call createMockCanvas() and remove all `as any`
assertions (update references to mockCanvas and any tests calling its methods
like pasteFromClipboard/_deserializeItems to use the typed instance).

Learning: In the `.github/workflows/pr-update-playwright-expectations.yaml` workflow in the Comfy-Org/ComfyUI_frontend repository, the snapshot update process is intentionally scoped to only add and update snapshot images. Deletions of snapshot files are handled explicitly outside this workflow and should not be suggested as part of this automation.

Learning: In TypeScript test files (e.g., any test under src), avoid duplicating interface/type definitions. Import real type definitions from the component modules under test and reference them directly, so there is a single source of truth and to prevent type drift. This improves maintainability and consistency across tests.

Learning: In src/renderer/extensions/vueNodes/components/ImagePreview.vue and LGraphNode.vue, keyboard navigation for image galleries should respond to node-level focus (via keyEvent injection from LGraphNode), not require focus within the image preview wrapper itself.

Learning: Prefer pure function declarations over function expressions (e.g., use function foo() { ... } instead of const foo = () => { ... }) for pure functions in the repository. Function declarations are more functional-leaning, offer better hoisting clarity, and can improve readability and tooling consistency. Apply this guideline across TypeScript files in Comfy-Org/ComfyUI_frontend, including story and UI component code, except where a function expression is semantically required (e.g., callbacks, higher-order functions with closures).

Learning: In Vitest v4, when mocking functions that may be called as constructors (using new), the mock implementation must use function() or class syntax rather than an arrow function. Arrow mocks can cause '<anonymous> is not a constructor' errors. This is a breaking change from Vitest v3 where mocks could use an arrow function. Apply this guideline to test files that mock constructor-like calls (e.g., in tests under tests-ui, such as ComboWidget.test.ts) and ensure mock implementations are defined with function() { ... } or class { ... } to preserve constructor behavior.

64-270: Test suite has gaps in coverage for audio/video node selection, error handling, and paste filtering logic.The tests cover main happy paths (image paste, workflow JSON, metadata) but miss several behavioral scenarios:
- Audio node selection: Test exists for creating new audio node, but no parallel test for pasting to an already-selected audio node (unlike the image node selection test at line 222)
- Video node paste: Implementation has video handling logic (lines 116-123), but zero tests exist
- shouldIgnoreCopyPaste filtering: Mock is set up but never tested for early return when
e.targetshould be ignored- Input/textarea exclusion: Implementation explicitly prevents paste in text inputs (lines 160-165), but no test covers this
- Parsing error fallback: Workflow JSON parsing has error recovery logic with 'workflow\n' prefix search, but only happy path is tested
- pasteClipboardItems errors: Error handling in base64 decode/JSON parse is not tested
Add tests for audio node selection, video paste, and the filtering/error paths to align with implementation coverage.

In @src/composables/usePaste.test.ts:
- Line 248: The test assigns mockNode to mockCanvas.current_node using an `as
any` assertion; replace this with proper typing by ensuring mockNode is
declared/constructed to implement the expected node interface (or the concrete
type used by current_node) and then assign directly (e.g., type mockNode as the
expected NodeType), or if unavoidable use `as unknown as ExpectedNodeType`
instead of `as any`; update the mockNode declaration and any helper factories
used in the test so that mockNode satisfies the shape expected by
mockCanvas.current_node.
- Around line 71-158: Tests overuse inline type assertions like "as unknown as
LGraphNode"; create a single typed mock factory (e.g., createMockImageNode) that
returns an object implementing LGraphNode with pos, pasteFile and pasteFiles,
centralizing a single assertion point, then replace every inline "as unknown as
LGraphNode" in the pasteImageNode tests with calls to this factory and pass its
result (and likewise use a typed mock for mockCanvas if needed) so all
assertions are properly typed without repeated casts.

Learning: In TypeScript test files (e.g., any test under src), avoid duplicating interface/type definitions. Import real type definitions from the component modules under test and reference them directly, so there is a single source of truth and to prevent type drift. This improves maintainability and consistency across tests.

Learning: Prefer pure function declarations over function expressions (e.g., use function foo() { ... } instead of const foo = () => { ... }) for pure functions in the repository. Function declarations are more functional-leaning, offer better hoisting clarity, and can improve readability and tooling consistency. Apply this guideline across TypeScript files in Comfy-Org/ComfyUI_frontend, including story and UI component code, except where a function expression is semantically required (e.g., callbacks, higher-order functions with closures).

Learning: In Vitest v4, when mocking functions that may be called as constructors (using new), the mock implementation must use function() or class syntax rather than an arrow function. Arrow mocks can cause '<anonymous> is not a constructor' errors. This is a breaking change from Vitest v3 where mocks could use an arrow function. Apply this guideline to test files that mock constructor-like calls (e.g., in tests under tests-ui, such as ComboWidget.test.ts) and ensure mock implementations are defined with function() { ... } or class { ... } to preserve constructor behavior.

src/composables/usePaste.test.ts (2)
1-63: Well-structured mock setup.The mock structure follows Vitest best practices with contained module mocks and proper cleanup return values. The separation of type imports (line 2) adheres to the coding guidelines.
161-290: Excellent test coverage for usePaste composable.The test suite comprehensively covers all major code paths including image/audio pasting, workflow JSON handling, conditional logic (shift key, existing nodes), and edge cases. The use of
vi.waitForfor async assertions is appropriate for testing event-driven behavior.The tests validate actual functionality rather than implementation details, which aligns with best practices for behavioral testing.
As per coding guidelines, the same type assertion concerns mentioned for pasteImageNode tests apply here (lines 172, 193).

In @src/composables/usePaste.test.ts:
- Around line 284-298: The test in usePaste.test.ts hard-codes the second
argument of the _deserializeItems call to {} which will break if options are
added; update the assertion for mockCanvas._deserializeItems to accept any
object shape (e.g., use Jest's expect.any(Object) or
expect.objectContaining({})) instead of {} so the test stays resilient to added
options while still validating the first arg is the parsed metadata.
- Around line 78-95: The test currently casts mockNode using an unsafe double
'unknown' cast; change the return value cast for LiteGraph.createNode from
"mockNode as unknown as LGraphNode" to the safer "mockNode as
Partial<LGraphNode> as LGraphNode" to tighten typing—update the mockNode
declaration/return in the test where LiteGraph.createNode is mocked (affects
mockNode, LiteGraph.createNode.mockReturnValue) so pasteImageNode continues to
receive a properly typed LGraphNode.
- Around line 54-58: Replace the current full-module replacement for the
'@/lib/litegraph/src/litegraph' mock with an importActual+override pattern so
you preserve all real exports and only override LiteGraph.createNode;
specifically, change the vi.mock factory to import the actual module (via
vi.importActual) and then return a shallow copy of that module with LiteGraph
replaced by a copy of actual.LiteGraph where createNode is replaced by vi.fn(),
ensuring other exports and LiteGraph methods remain intact for usePaste tests.
- Around line 97-112: The test is brittle because it insists both pasteFile and
pasteFiles are called; update the assertion to verify that at least one API was
used instead: after calling pasteImageNode (reference function pasteImageNode
and mockNode), replace the two strict expects with a check like const used =
mockNode.pasteFile.mock.calls.length > 0 ||
mockNode.pasteFiles.mock.calls.length > 0; expect(used).toBe(true); and
optionally assert the corresponding args when each method was called (e.g., if
pasteFile was called assert it was calledWith(file), if pasteFiles was called
assert it was calledWith([file])) so the test passes if implementation uses
either path.
- Around line 33-38: The mock for useEventListener installs real DOM listeners
but never calls their cleanup; modify the test to hoist an array via
vi.hoisted() (e.g., const _cleanups = vi.hoisted(() => [])) and in the
useEventListener mock (the vi.mock replacement) push each returned cleanup into
that array when invoked, then add an afterEach(() => _cleanups.forEach(fn =>
fn())) to ensure all listeners registered by usePaste() are removed between
tests; reference the useEventListener mock, usePaste(), vi.hoisted(), and
afterEach() when making the change.
- Around line 199-218: Update the MP3 MIME type in the "should handle audio
paste" test in usePaste.test.ts: change the File creation in the test (variable
name "file") to use the standard MIME string "audio/mpeg" instead of "audio/mp3"
so the test aligns with metadata parsing and other code that expects
"audio/mpeg" (affects the ClipboardEvent paste handling and expectations around
LiteGraph.createNode('LoadAudio') and mockNode.pasteFile).

Timestamp: 2026-01-09T02:07:54.558Z
Learning: In test files (e.g., any .test.ts or .test.tsx under src/...), when you create mock objects that partially implement an interface (such as LGraphNode), prefer casting with as Partial<InterfaceType> as InterfaceType rather than as any or as unknown as InterfaceType. This makes the incomplete implementation explicit while preserving type safety, improving readability and maintainability of tests.

Learning: Prefer pure function declarations over function expressions (e.g., use function foo() { ... } instead of const foo = () => { ... }) for pure functions in the repository. Function declarations are more functional-leaning, offer better hoisting clarity, and can improve readability and tooling consistency. Apply this guideline across TypeScript files in Comfy-Org/ComfyUI_frontend, including story and UI component code, except where a function expression is semantically required (e.g., callbacks, higher-order functions with closures).

Learning: In Vitest v4, when mocking functions that may be called as constructors (using new), the mock implementation must use function() or class syntax rather than an arrow function. Arrow mocks can cause '<anonymous> is not a constructor' errors. This is a breaking change from Vitest v3 where mocks could use an arrow function. Apply this guideline to test files that mock constructor-like calls (e.g., in tests under tests-ui, such as ComboWidget.test.ts) and ensure mock implementations are defined with function() { ... } or class { ... } to preserve constructor behavior.

1-12: Good baseline setup; keep type-only imports separate (already done).
No issues with the import/type split here.
70-76: beforeEach is fine; mockinggraph.addreturn value matches LiteGraph behavior.
Looks good.
114-131: Multi-image case assertion matches expected behavior (first file routed + all files passed).
Looks good.
133-146: No-image no-op case is good (prevents accidental node mutation).
Looks good.
148-165: Non-image filtering coverage is good.
Looks good.
178-197: Good behavioral test, but depends on happy-dom supportingClipboardEvent/DataTransfercorrectly.
If this ever flakes in CI, consider constructing a minimal event object and invoking the registered handler directly (via captured listener) instead of relying on DOM constructors.
220-234: Workflow JSON paste coverage is good (asserts parsed object passed toapp.loadGraphData).
Looks good.
251-270: Nice: usesPartial<LGraphNode> as LGraphNodepattern for incomplete mocks.
This matches the preferred approach in test files. Based on learnings, this is the right casting style.
272-282: Fallback tocanvas.pasteFromClipboardis covered well.
Looks good.
236-249: Shift-down guard is good; consider also asserting no fallback paste happened.
Optional:expect(mockCanvas.pasteFromClipboard).not.toHaveBeenCalled()to ensure full suppression.⛔ Skipped due to learnings

13-27: Drop redundantas unknown as LGraphCanvascasts at call sites;mockCanvasis already typed.
Right now you castmockCanvasagain in multiple tests even though it’s alreadyLGraphCanvas. Also preferPartial<T> as Toverunknowncasts in tests (per learnings). Based on learnings, avoidunknowncasts when aPartial<>cast expresses intent.⛔ Skipped due to learnings

In @src/composables/usePaste.test.ts:
- Around line 263-280: The mock node's type assertion is overly complex: replace
the mixed "as unknown as Partial<LGraphNode> as LGraphNode" pattern on the
mockNode declaration with a direct cast like "as Partial<LGraphNode> as
LGraphNode" so the mock remains a Partial for test convenience but satisfies
LGraphNode typing; update the mock declaration used in the test (mockNode,
referenced by usePaste and isImageNode) accordingly.
- Around line 106-122: The tests use unsafe "as unknown as LGraphNode" casts for
mockNode and similar mocks; replace these with explicit partial assertions like
"as Partial<LGraphNode> as LGraphNode" for LiteGraph.createNode returns and any
other mocks (e.g., mockNode) so incomplete mock implementations are explicit;
update every occurrence in this test file (including the instances called out
around createMockNode / LiteGraph.createNode) to use Partial<LGraphNode> as
LGraphNode.

Learning: In Playwright tests in the Comfy-Org/ComfyUI_frontend repository, the `toPass()` assertion method implements incremental backoff during retries, so increasing the timeout value (e.g., to 5000ms) is sufficient for handling async operations without being overly aggressive.

Learning: In test files (e.g., any .test.ts or .test.tsx under src/...), when you create mock objects that partially implement an interface (such as LGraphNode), prefer casting with as Partial<InterfaceType> as InterfaceType rather than as any or as unknown as InterfaceType.

Learning: In the ComfyUI_frontend repository, lint rules require keeping 'import type' statements separate from non-type imports, even if importing from the same module. Do not suggest consolidating them into a single import statement. Ensure type imports remain on their own line (import type { ... } from 'module') and regular imports stay on separate lines.

Learning: In the `.github/workflows/pr-update-playwright-expectations.yaml` workflow in the Comfy-Org/ComfyUI_frontend repository, the snapshot update process is intentionally scoped to only add and update snapshot images. Deletions of snapshot files are handled explicitly outside this workflow and should not be suggested as part of this automation.

Learning: In TypeScript test files (e.g., any test under src), avoid duplicating interface/type definitions. Import real type definitions from the component modules under test and reference them directly, so there is a single source of truth and to prevent type drift. This improves maintainability and consistency across tests.

Learning: In src/renderer/extensions/vueNodes/components/ImagePreview.vue and LGraphNode.vue, keyboard navigation for image galleries should respond to node-level focus (via keyEvent injection from LGraphNode), not require focus within the image preview wrapper itself. This allows users to navigate the gallery with arrow keys immediately when the node is focused/selected.

Learning: In the ComfyUI_frontend project, Zod is on v3.x. Do not suggest Zod v4 standalone validators (z.uuid, z.ulid, z.cuid2, z.nanoid) until an upgrade to Zod 4 is performed. When reviewing TypeScript files (e.g., src/platform/remote/comfyui/jobs/jobTypes.ts) validate against Zod 3 capabilities and avoid introducing v4-specific features; flag any proposal to upgrade or incorporate v4-only validators and propose staying with compatible 3.x patterns.

Learning: Prefer pure function declarations over function expressions (e.g., use function foo() { ... } instead of const foo = () => { ... }) for pure functions in the repository. Function declarations are more functional-leaning, offer better hoisting clarity, and can improve readability and tooling consistency. Apply this guideline across TypeScript files in Comfy-Org/ComfyUI_frontend, including story and UI component code, except where a function expression is semantically required (e.g., callbacks, higher-order functions with closures).

Learning: When accessing reactive properties from Pinia stores in TypeScript files, avoid using .value on direct property access (e.g., useStore().isOverlayExpanded). Pinia auto-wraps refs when accessed directly, returning the primitive value. The .value accessor is only needed when destructuring store properties or when using storeToRefs().

Learning: In test files, prefer selecting or asserting on accessible properties (text content, aria-label, role, accessible name) over data-testid attributes. This ensures tests validate actual user-facing behavior and accessibility, reducing reliance on implementation details like test IDs.

Learning: In Vitest v4, when mocking functions that may be called as constructors (using new), the mock implementation must use function() or class syntax rather than an arrow function. Arrow mocks can cause '<anonymous> is not a constructor' errors. This is a breaking change from Vitest v3 where mocks could use an arrow function. Apply this guideline to test files that mock constructor-like calls (e.g., in tests under tests-ui, such as ComboWidget.test.ts) and ensure mock implementations are defined with function() { ... } or class { ... } to preserve constructor behavior.

Learning: This repository uses CI automation to format code (pnpm format). Do not include manual formatting suggestions in code reviews for Comfy-Org/ComfyUI_frontend. If formatting issues are detected, rely on the CI formatter or re-run pnpm format. Focus reviews on correctness, readability, performance, accessibility, and maintainability rather than style formatting.

1-314: Well-structured test suite with good behavioral coverage.The test file provides comprehensive coverage of the refactored paste functionality:
- Tests both the exported
pasteImageNodehelper and theusePastecomposable- Covers key scenarios: image/audio paste, workflow JSON, modifier keys, existing nodes, and clipboard metadata
- Uses proper async assertions with
vi.waitFor()- Implements appropriate mock cleanup in
beforeEachThe tests validate actual behavior (method calls with expected arguments) rather than just testing mock return values.

Summary
Added feature to drag image into workflow to create a load image node if the image does not have workflow meta data.
Also added tests for usePaste.ts as I extracted code to be reusable there and there wasn't any tests.
Changes
app.ts handleFile updated,
usePaste.ts usePaste updated with new method pasteImageNode
Review Focus
Not sure if it has an issue, just has a notion task.
