Resolving the React Hook "useSelector" Error: Proper Component Naming in React

Introduction

If you're building applications with React and Redux, you might encounter various errors while using hooks. One common error is related to the useSelector hook, which can be quite frustrating for developers, especially for those new to React hooks. The error message states that the hook is being called in a function that is neither a React function component nor a custom React Hook function. In this guide, we will break down this issue and provide a clear solution.

Understanding the Error

You received the following error message:

This error occurs primarily because of two key reasons:

Component Naming Conventions: In React, function components must start with an uppercase letter (PascalCase). This allows React to differentiate between native HTML tags and custom components.

Hook Usage Rules: React hooks are functions that must follow specific rules, most importantly that they should only be called from React function components or other hooks.

Solution Breakdown

To resolve this issue, follow these organized steps:

1. Rename the Component

Change the function name posts to Posts. This simple adjustment aligns with React's naming conventions.

2. Use useEffect for Side Effects

If you need to log the state or perform side effects, use the useEffect hook. This ensures that your component remains a pure function, which means it just returns JSX without causing side effects directly.

Conclusion

By making the outlined changes, you can effectively resolve the useSelector error and adhere to React’s best practices. Always ensure that your function components are named with an uppercase letter and that hooks are used correctly. Following these guidelines will not only eliminate errors but also lead to cleaner and more maintainable React code.
