+#### Case Sensitive Matching
+
+By default, glob pattern matching is case-sensitive. You can use the `caseSensitiveMatch` option to change this behavior:
+
+```ts twoslash
+import 'vite/client'
+// ---cut---
+const modules = import.meta.glob('./dir/module*.js', {
+  caseSensitiveMatch: false,
+})
+```
+
+With `caseSensitiveMatch: false`, the glob will match files regardless of case (e.g., `Module.js`, `module.js`, `MODULE.js` will all be matched by `module*.js`).
