React Review Audit

Score: 97/100 · 0 errors · 4 warnings

Fix the following React Review diagnostics in my codebase.

## Warnings (4)

1. [warning] no-transition-all — src/components/FileDropzone.tsx:42
   transition: "all" animates every property including layout — list only the properties you animate

2. [warning] no-inline-exhaustive-style — src/components/FileDropzone.tsx:33
   8 inline style properties — extract to a CSS class, CSS module, or styled component for maintainability and reuse

3. [warning] js-index-maps — src/services/uploadService.ts:34
   array.find() in a loop is O(n*m) — build a Map for O(1) lookups

4. [warning] no-cascading-set-state — src/hooks/useFileUpload.ts:26
   3 setState calls in a single useEffect — consider using useReducer or deriving state

⚠️ Warnings (4)

no-transition-all

transition: "all" animates every property including layout — list only the properties you animate

List specific properties: transition: "opacity 200ms, transform 200ms" — or in Tailwind use transition-colors, transition-opacity, or transition-transform

src/components/FileDropzone.tsx:42

no-inline-exhaustive-style

8 inline style properties — extract to a CSS class, CSS module, or styled component for maintainability and reuse

Move styles to a CSS class, CSS module, Tailwind utilities, or a styled component — inline objects with many properties hurt readability and create new references every render

src/components/FileDropzone.tsx:33

js-index-maps

array.find() in a loop is O(n*m) — build a Map for O(1) lookups

Build an index Map once outside the loop instead of array.find(...) inside it

src/services/uploadService.ts:34

no-cascading-set-state

3 setState calls in a single useEffect — consider using useReducer or deriving state

Combine into useReducer: const [state, dispatch] = useReducer(reducer, initialState)

src/hooks/useFileUpload.ts:26
