What you'll learn

  • Build polymorphic React components
  • Apply intermediate Typescript utility types
  • Practically use Typescript generics
  • Use Typescript to restrict the polymorphic prop to accept only valid HTML elements
  • Based on the generic polymorphic prop, use Typescript to enforce only valid props of the passed HTML element
  • Build a reusable Polymorphic utility
  • Handle strongly typed Polymorphic refs

Requirements

  • You already know some React
  • You already know some Typescript (at least the basics)

Description

Polymorphic components?



You've probably used them before ... If you've used material UI's component prop or Chakra UI's as prop, then you've already encountered polymorphic React components.



In this class, you will learn to build your own polymorphic component that can be rendered as any valid HTML element. More importantly, you will learn to strongly type its allowed props based on the supplied element type. There will be many use cases and edge cases discussed along the way to help you build more robust reusable React components with a great developer experience.



How can you apply this knowledge?



Build more flexible reusable components

Apply the gained knowledge to building your own design system

Explore intermediate Typescript concepts for truly strongly typed polymorphic components



Prerequisites



You are familiar with React basics

You are familiar with Typescript basics



Who is this class for?



React developers building design systems

React developers building reusable components

React Typescript developers

Other curious intermediate React developers



In summary, this is not a beginner's course. You need to know some React, and some Typescript (the basics at least i.e., you know what "types" are).

You will learn intermediate typescript in this course. It'll be practical, effective and straight to the point - a course you will actually complete.

You will learn to build your own polymorphic component that can be rendered as any valid HTML element. That's easy! What's not so easy is strongly typing its allowed props based on the supplied element type. Restricting the component props dynamically, type-safe the passed refs to the props and even building a utility you can reuse on any other reusable component.



There will be many use cases and edge cases discussed along the way to help you build more robust reusable React components with a great developer experience.
