Best Practices for Checking PropTypes in React Components using TypeScript

JavaScript functions that return React elements are known as React components. These are the parameters that govern what will be added to the DOM. In addition, react components, like functions, may receive props as arguments, resulting in dynamically returned items.

Props can be of any data type, although component data types may differ. Component A, for example, may anticipate a name argument with a text data type, but component B may anticipate an age argument with a numeric data type. Likewise, D may anticipate an onClick argument with a Function data type, but C may expect a post parameter with an object data type with characteristics like title and date.

How can we tell our component what kind of data it should expect?

This may be done in various methods, but this post will focus on PropTypes and TypeScript. Despite holding identical goals, these two techniques operate in different ways. So we’ll go through what these tools are, how to use them, and tell them apart before trying more advanced techniques.

Prior knowledge of PropTypes and TypeScript is necessary for a thorough understanding of this article. You’ll also require an integrated development environment (IDE), such as Visual Studio Code.

PROPTYPES

PropTypes is a type-checking tool for props in React apps that can be used at runtime. The PropTypes efficiency has been provided through the prop-types package since React 15.5. PropTypes let you specify the props that are expected in a component, such as whether they are mandatory or optional. You’ll get a warning in the browser’s JavaScript console if you provide a different type to an element or miss a required prop:
