Build strongly typed polymorphic components with React and TypeScript
Blog post from LogRocket
This comprehensive guide provides a detailed explanation on building strongly typed polymorphic React components using TypeScript. It delves into real-world examples of polymorphic components, such as Chakra UI's "as" prop and MUI's "component" prop, and outlines how to build a simple polymorphic component while addressing potential issues like accepting invalid HTML elements and attributes. The guide further explains how to use TypeScript to create strongly typed polymorphic components, ensuring that only valid HTML element strings are passed, and handling component attributes with TypeScript generics. It introduces the concept of making components reusable, supporting refs, and creating a utility for polymorphic types to enhance reusability across different projects. The tutorial emphasizes properly handling default attributes, omitting generic component props, and supporting refs in polymorphic components while using TypeScript and React's forwardRef function. The guide concludes by offering a robust solution for implementing polymorphic components in React with TypeScript, encouraging developers to leverage these techniques for better type safety and developer experience.
