In this post, we'll tackle a common problem: how to change the background color of a component based on prop values. You might have a button or any component that needs to have its background color change dynamically based on user selections or themes. We will specifically look at handling three color options passed through props: primary, secondary, and brand. Understanding the Problem You want to create a React component that changes its background color based on a prop value. Here's how the colors will be assigned: primary ➜ blue secondary ➜ green brand ➜ yellow With this understanding, you can create a more visually dynamic user interface that engages users better through color associations. Setting Up the Component Here’s what we want our component to accept as props: Props Definition [[See Video to Reveal this Text or Code Snippet]] Basic Structure of the Component We'll create a functional component in TypeScript that leverages these props: [[See Video to Reveal this Text or Code Snippet]] Implementing Color Mapping Now, to apply the correct background color based on the backgroundColor prop, we can set up a simple mapping. This will allow us to translate the string values into the respective color values. Color Mapping Here's how to define this mapping: [[See Video to Reveal this Text or Code Snippet]] Updated Component Code Integrating the color mapping into our Button component: [[See Video to Reveal this Text or Code Snippet]] Summary By defining a COLORS mapping object, your React component can change its background color dynamically based on the backgroundColor prop. This way, you achieve cleaner code, better maintainability, and enhanced functionality. Key Takeaways: Use type definitions to manage props effectively with TypeScript. Create mapping between props and actual values you want to apply. Leverage functional components for better performance and easier debugging. Now you have a functional, dynamic component that changes colors simply based on the props passed to it! Happy coding!
