TypeScript’s generics are a powerful tool that enables developers to ensure their code is flexible and reusable. Using generics can help developers manage exactly what types are used in functions and components around the application.

In this course, we’ll first get an overview of TypeScript generics and create generic search and sort functions. Next, we’ll create a React component for searching that would leverage our generic search function. Then, we’ll create a generic function and a React component for sorting and filtering, respectively. Finally, we’ll bring all these functionalities together to create one component that can manage searching, sorting, and filtering of any data passed to it.

By the end of this course, you'll know how to write generic TypeScript functions and craft React components that use TypeScript generics. You’ll also be able to deploy concise solutions in both business logic and user interface senses for searching, sorting, and filtering data on client side in applications.

Building User Interfaces and Functions with TypeScript and React

It’s time to create a way for users to be able to provide input and take advantage of our powerful `genericSearch` function.

# Creating a search input component

To get started, we’ll create a new React component called `SearchInput`. We’ll use both `label` and `input` HTML tags to build the `SearchInput`.





import * as React from "react";

export function SearchInput() {
  return (
    <>
      <label htmlFor="search" className="mt-3">
        Search here
      </label>
      <input
        id="search"
        className="form-control full-width"
        type="search"
        placeholder="Search..."
        aria-label="Search"
      />
    </>
  );
}

Now we need to make the JSX input element stateful. We’ll add a prop interface, `ISearchInputProps`, with a `setSearchQuery` property so that we can set a query in the parent component. The `setSearchQuery` is a function that accepts a `searchQuery` value of type string and has no type `void` return value.




Create a search input React component that can provide a query via callback prop.
