Understanding Props in Styled Components with React

When working with React and styled components, it’s common to want to create reusable components that can have dynamic styles based on props. In this guide, we'll explore how to effectively use props in styled components, specifically addressing the problem of styling our custom components based on their properties.

The Problem

Let’s consider a scenario where you have created a custom slider component using Material UI and styled components. Here's the initial implementation:

This component works perfectly for a single instance of the slider. However, the challenge arises when you want multiple instances of the PrettoSlider, each with different colors, like so:

The goal is to make the slider's track color change dynamically based on the color prop being passed to each instance. The initial attempts to modify the styled component to achieve this resulted in errors related to TypeScript expecting a specific type for props. Let’s break down how to correctly implement this.

Solution: Passing Props in Styled Components

Step 1: Define the Styled Component with Props

To allow for dynamic styling based on props, modify the definition of your styled component. Instead of relying solely on the styled function, you can use function interpolation. Here’s how to declare the PrettoSlider to accommodate the color prop:

Step 2: Adjust TypeScript Types

If you’re using TypeScript, it’s essential to specify the type for your props to avoid type errors. You can define the expected props as follows:

Step 3: Usage Example

Now, you can freely use your PrettoSlider component with different color props:

Step 4: Handling Multiple Conditional Styles

If you have more complex conditions (such as a dark mode theme), styled-components offers a powerful way to manage that using the css utility. Here’s an example of how you might implement dark mode support:

Conclusion

Using props in styled components can greatly enhance the versatility and usability of your React components. By following the steps outlined above, you can easily create components that adapt their styles based on the properties passed to them. This approach not only leads to cleaner and more maintainable code but also ensures a smoother user experience with customizable components.

Now you can confidently implement dynamic styling in your React applications using styled components!
