Creating Custom Hooks for Reusable Logic
In React, custom hooks allow you to extract reusable logic into functional components. This facilitates code reuse and improves code organization, keeping components cleaner and more manageable.
Synopsis
A custom hook is a function that allows you to extract logic from a component to be reused in others. Any hook can be used within a custom hook, such as useState, useEffect, or any other hook provided by React or created by the user.
This approach is useful when you have multiple components that share the same logic. Instead of duplicating that logic in each component, you can encapsulate it within a custom hook and reuse it.
The following example shows how to create a custom hook to make an API request.
Purpose
Custom hooks are useful for:
- Reusing logic between components without duplicating it.
- Separating component logic, keeping components cleaner and easier to manage.
- Creating custom hooks to perform specific tasks, such as API requests or managing form state.
