React Hook Generator
Generate custom React hooks from templates with TypeScript support
About this ToolHow it works, benefits & use casesTap to collapse
Custom React hooks all start from the same boilerplate — this generator writes it for you. Enter a name (it is auto-prefixed with "use" if you forget) and pick a hook type, and it scaffolds idiomatic code for that pattern: a state hook built on useState, an effect hook with useEffect and an editable dependency array, a ref hook with useRef, a memoised value with useMemo, a stable callback with useCallback, a context consumer with createContext/useContext and a provider guard, or a general-purpose custom hook returning value/setValue/reset. Two toggles control the output: TypeScript types (typed signatures and return types versus plain JS) and JSDoc comments with usage examples. For effect hooks you can supply a comma-separated dependency list that lands in the dependency array. The code updates live, previews the filename (.ts or .js), and can be copied, downloaded, or shared via URL — all in the browser.
How to Use
- 1Enter a hook name in the Hook Name field — it is prefixed with "use" automatically if needed.
- 2Choose a Hook Type: Custom, State, Effect, Ref, Memo, Callback, or Context.
- 3For an Effect hook, fill the Dependencies field with comma-separated variables to populate the dependency array.
- 4Toggle "Include TypeScript types" and "Include JSDoc comments" to shape the output.
- 5Click "Generate Hook", then copy, download (as .ts/.js), or share the result via its URL.
Key Benefits
- Scaffolds seven hook patterns: state, effect, ref, memo, callback, context, and custom
- Auto-prefixes the name with "use" to follow React conventions
- TypeScript toggle adds typed signatures and return types, or emits plain JS
- JSDoc toggle adds documentation plus an inline usage example
- Effect hooks accept a comma-separated dependency list for the dependency array
- Context hooks include a provider guard that throws if used outside the provider
- Live preview, correct .ts/.js filename, and copy/download/share output
Common Use Cases
- Bootstrapping a new custom hook without retyping the imports and boilerplate
- Generating a typed context consumer hook with the standard provider guard
- Scaffolding a useEffect hook with the right dependency array for a side effect
- Producing a useCallback or useMemo skeleton to drop computation logic into
- Teaching the idiomatic shape of each React hook pattern with copyable examples
Hook Configuration
Name will be prefixed with 'use' if not already

Usage Tips
- Hook names should start with "use" (will be auto-prefixed)
- Custom hooks can combine multiple React hooks
- Context hooks require a provider component
- Use TypeScript for better type safety and IntelliSense

Seven: a state hook (useState), an effect hook (useEffect with a dependency array), a ref hook (useRef), a memo hook (useMemo), a callback hook (useCallback), a context hook (createContext + useContext with a provider guard), and a general custom hook that returns value, setValue, and reset.
Yes. React requires hook names to start with "use". If you type a name without it, the generator capitalises your name and prepends "use" — so "counter" becomes "useCounter" — keeping the output convention-compliant.
