React Hooks best practices

I've been working with React Hooks for a while now, and I'm curious about the community's best practices. There are so many ways to structure hooks, and I want to make sure I'm following the most effective patterns.

Some specific questions:

  • How do you organize custom hooks in larger projects?
  • What's your approach to useEffect dependencies to avoid infinite loops?
  • Do you have any patterns for managing complex state with useReducer?
  • How do you test custom hooks effectively?

I'd appreciate any insights or resources you can share!

Great questions! For custom hooks organization, I follow a pattern of grouping them by domain (e.g., auth hooks, api hooks, ui hooks) rather than by component.

For useEffect dependencies, I use the ESLint plugin for hooks which catches most issues. I also try to keep effects small and focused on a single concern.

I'll add that for useReducer, I find it helpful to colocate reducers with their related hooks and context. This keeps the state management logic together.

For testing, React Testing Library works well with custom hooks. You can create a test component that uses the hook and then test the component's behavior.

Kent C. Dodds has some excellent articles on testing custom hooks that I'd recommend checking out.
