Simplifying State Management in React with useState Alternatives

In React development, managing state can become cumbersome, particularly when using multiple useState hooks for different pieces of state. This approach can lead to lengthy and repetitive code. Are you finding yourself overwhelmed with states and looking for a more efficient way to handle them? If you’ve ever felt the same way, you’re not alone! In this guide, we will explore an alternative approach to using useState that can help streamline your code.

The Problem with Multiple States

As developers, we often rely on multiple useState hooks to keep track of our app's state. For example, look at the following code snippet:

In this example, the Source component manages multiple pieces of state. When importing this component elsewhere, you may find yourself needing to destructure the entire array:

This can get messy quickly, especially if you're only interested in certain pieces of state. So what can we do to clean things up?

A Better Approach: Returning an Object

Instead of returning an array of states and their setters, you can return an object with named properties. This approach allows you to access only what you need without dealing with unnecessary destructuring. Here's how to implement this:

Step 1: Refactor Your Custom Hook

Modify the Source component to return an object instead of an array. It’s a good practice to prefix custom hooks with use:

Step 2: Destructure the Object as Needed

Now that the useSource hook returns an object, you can destructure only the pieces of state you require:

This leads to cleaner and more maintainable code, allowing you to focus only on the relevant states.

Considering Scope of State

One important consideration is that calling useSource generates separate instances of the states every time it's invoked. This means if you need the same data shared among various components, each instance will have its own, separate state unless you handle it properly:

Recommended Structure: Single Source State

It's often beneficial to call your custom hook just once and pass the returned state down through props. Here's how you can structure your components:

By following this pattern, you maintain a single source of truth for your states, while still being able to pull out specific states wherever necessary.

Conclusion

Managing multiple states in a React application doesn't have to be a headache. By returning an object from your custom hooks instead of an array, you can simplify your code, enhance readability, and effectively manage your states. Going forward, use this insightful method to keep your React components organized and concise.
