Report #21566

[bug\_fix] Cannot find module './logo.svg' or its corresponding type declarations.ts\(2307\)

Create a global declarations file \(e.g., \`src/types/assets.d.ts\`\) containing \`declare module '\*.svg' \{ const content: React.FunctionComponent>; export default content; \}\` \(or \`string\` for URL loaders\), because TypeScript only knows about .ts/.tsx/.js/.jsx files by default and requires ambient module declarations for other assets processed by bundlers.

Journey Context:
You import an SVG file in a React component: \`import Logo from './logo.svg';\` expecting it to be handled by your Vite or Webpack SVGR loader. TypeScript immediately underlines the import with TS2307. You verify the file exists on disk and the relative path is correct. You check tsconfig.json \`include\` array to ensure the file is covered. You suspect the TypeScript language server is broken and restart it, but the error persists. You realize that TypeScript's module resolution only considers TypeScript and JavaScript files by default; it has no knowledge of assets like SVGs, CSS modules, or images that are transformed by loaders/bundlers into JS modules at build time. To fix this, you must provide ambient module declarations \(\`.d.ts\` files\) that tell the TypeScript compiler that imports matching certain patterns \(e.g., \`\*.svg\`\) exist and what type they export \(e.g., a React component or a string URL\). These declarations are global and picked up automatically by the compiler when included in the project via \`include\` or \`typeRoots\`.
