+# useChangeCase
+
+Reactive wrapper for [`change-case`](https://github.com/blakeembrey/change-case).
+
+Subsitutes `useCamelCase`, `usePascalCase`, `useSnakeCase`, `useSentenceCase`, `useCapitalize`, etc.
+
+## Install
+
+```bash
+npm i change-case@^5
+```
+
+## Usage
+
+```ts
+import { useChangeCase } from '@vueuse/integrations/useChangeCase'
+
+// `changeCase` will be a computed
+const changeCase = useChangeCase('hello world', 'camelCase')
+changeCase.value // helloWorld
+changeCase.value = 'vue use'
+changeCase.value // vueUse
+// Supported methods
+// export {
+//   camelCase,
+//   capitalCase,
+//   constantCase,
+//   dotCase,
+//   headerCase,
+//   noCase,
+//   paramCase,
+//   pascalCase,
+//   pathCase,
+//   sentenceCase,
+//   snakeCase,
+// } from 'change-case'
+```
+
+or passing a `ref` to it, the returned `computed` will change along with the source ref's changes.
+
+Can be passed into `options` for customization
+
+```ts
+import { useChangeCase } from '@vueuse/integrations/useChangeCase'
+import { shallowRef } from 'vue'
+
+const input = shallowRef('helloWorld')
+const changeCase = useChangeCase(input, 'camelCase', {
+  delimiter: '-',
+})
+changeCase.value // hello-World
+input.value = 'vue use'
+changeCase.value // vue-Use
+```
+
+## Type Declarations
+
+```ts
+type EndsWithCase<T> = T extends `${infer _}Case` ? T : never
+type FilterKeys<T> = {
+  [K in keyof T as K extends string ? K : never]: EndsWithCase<K>
+}
+type ChangeCaseKeys = FilterKeys<typeof changeCase>
+export type ChangeCaseType = ChangeCaseKeys[keyof ChangeCaseKeys]
+export declare function useChangeCase(
+  input: MaybeRef<string>,
+  type: MaybeRefOrGetter<ChangeCaseType>,
+  options?: MaybeRefOrGetter<Options> | undefined,
+): WritableComputedRef<string>
+export declare function useChangeCase(
+  input: MaybeRefOrGetter<string>,
+  type: MaybeRefOrGetter<ChangeCaseType>,
+  options?: MaybeRefOrGetter<Options> | undefined,
+): ComputedRef<string>
+```
