Hook Generator
Describe a custom React hook in plain English and get runnable TypeScript code.
What it does
The Hook Generator turns a plain-English description of behavior into a complete, runnable custom React hook in TypeScript. Describe what you want to track or encapsulate — online status, a debounced value, a media query — and it returns the full hook with JSDoc and a short usage example.
It's built for working developers who already know hooks but don't want to hand-write the same boilerplate again. The output uses modern function-component APIs and proper cleanup, so it's safe to paste straight into a project.
Example
You describe
A hook that returns whether the user is currently online or offline.
You get
useOnlineStatus(): boolean • Subscribes to window online/offline events • Cleans up listeners on unmount • Includes JSDoc + usage example
Use cases
- Scaffolding common hooks (useDebounce, useLocalStorage, useMediaQuery) without copy-pasting from memory.
- Turning a vague idea into a typed starting point you can refine.
- Learning idiomatic hook structure — effects, cleanup, and dependency handling done correctly.
FAQ
Is the generated hook TypeScript or JavaScript?
Always TypeScript, with types on arguments and return values. Use the Code Converter if you need to strip types down to plain JavaScript.
Will it handle cleanup and dependencies correctly?
Yes — generated hooks subscribe and unsubscribe properly and declare effect dependencies. Always review the output before shipping, as with any generated code.
Can I describe complex hooks?
Yes. The more specific your description (inputs, return shape, edge cases), the closer the result. You can iterate by refining the prompt.
