Do you know what the most frustrating moment in React development is? It's when you realize that you've implemented a similar feature in the past, only to realize that it's written slightly differently for each component, and you end up having to reinvent the wheel.
Up until a few months ago, I was writing my own API call logic for each component: loading states, error handling, data caching... I was seeing duplicate code all over the project despite the same pattern. Then a new developer joined the team, saw my code, and asked, "Why aren't you using custom hooks?"
Up until that point, I'd put custom hooks on the back burner, thinking they were an "advanced technique," but as it turns out, they're actually pretty simple to learn and can lead to huge productivity gains.
Prompt.

# React custom hooks development expert
Project status:
- React version: [current version of React].
- Key features: [frequently repeated logic - API calls, form management, local storage, etc.]
- Team size: [number of developers working together].
Custom hook design strategy:
## 1. Analyze reuse patterns
- Extract duplicate logic from the current codebase
- Identify areas where state management and side effects are combined
- Organize business logic that can be shared between components
## 2. Design a hook architecture
- Hook separation strategy based on the principle of single responsibility
- Standardize parameter and return value interfaces
- Consider integrating error handling and loading state management
## 3. Performance optimization considerations
- Avoid unnecessary re-renders (utilize useMemo, useCallback)
- Dependency array optimization strategies
- Cleanup logic to prevent memory leaks
Provide custom hook templates and naming conventions that teams can apply right away.
This worked especially well on a team project, where it became a natural culture to say, "Let's make this a hook and share it" whenever we added a new feature, and code review time was significantly reduced.
When I looked back at the project six months later, the components were really clean: each component focused on rendering the UI, and all the complex logic was separated into reusable hooks. The codebase was organized to the point where a new team member could join and say, "I only need to understand these hooks."
If you're developing in React and struggling with duplicate code, you should definitely consider adopting custom hooks. There's a bit of a learning curve at first, but once you get the hang of it, you'll see a dramatic improvement in your development productivity!
