If you are a developer working with React and TypeScript, you may have come across the challenge of adding styles and CSS to your React components. Fortunately, TypeScript offers a variety of tools and techniques to help you master style types in your React components.

In this article, we will explore the correct TypeScript type for the style attribute, how to pass CSS styles as props in React TypeScript, using the className prop, the StyleSheet module, Emotion, and more. We will also cover some best practices and helpful points to optimize your React components using TypeScript and CSS.

The Correct TypeScript Type for the Style Attribute in React is React.CSSProperties

When adding styles to react components using TypeScript, it is important to use the correct type for the style attribute. The correct type is React.CSSProperties , which is a predefined type in React.

React.CSSProperties is an interface that defines the properties that can be used in a style object. It includes properties such as background-color , border , color , font-size , and more.

Using React.CSSProperties ensures that your styles are correctly typed and that you can catch any errors at compile time. Here is an example of using React.CSSProperties in a React component:

import React from 'react';interface ButtonProps < label: string; style: React.CSSProperties; >const Button: React.FC = () => < return > ; >;export default Button; 

To Pass CSS Styles as Props in React TypeScript, Use style: React.CSSProperties

Another way to add styles to your React components using TypeScript is to pass them as props. To pass css styles as props in react typescript , use the style prop with the React.CSSProperties type.

Here is an example of using the style prop in a React component:

import React from 'react';interface CardProps < title: string; description: string; style: React.CSSProperties; >const Card: React.FC = () => < return ( > ); >;export default Card; 

Using the style prop with React.CSSProperties ensures that your styles are correctly typed and that you can catch any errors at compile time.

The className Prop Should Use a Lowercase s for string

When adding CSS classes to your React components using TypeScript, it is important to use the correct type for the className prop. The correct type is string , with a lowercase s .

Here is an example of using the className prop in a React component:

import React from 'react';interface ButtonProps < label: string; className: string; >const Button: React.FC = () => < return > ; >;export default Button; 

Using string with a lowercase s ensures that your className prop is correctly typed and that you can catch any errors at compile time.

Use the StyleSheet Module to Keep Each Stylesheet Inline with Its Corresponding View

The StyleSheet module is a useful tool for keeping each stylesheet inline with its corresponding view in React. The StyleSheet module allows you to define styles in a separate file and import them into your React components.

Here is an example of using the StyleSheet module in a React component:

import React from 'react'; import from 'react-native';const styles = StyleSheet.create(< container: < flex: 1, alignItems: 'center', justifyContent: 'center', backgroundColor: '#F5FCFF', >, welcome: < fontSize: 20, textAlign: 'center', margin: 10, >, instructions: < textAlign: 'center', color: '#333333', marginBottom: 5, >, >);interface AppProps < title: string; >const App: React.FC = () => < return ( > > > To get started, edit App.tsx  ); >;export default App; 

Using the StyleSheet module keeps your styles organized and makes it easier to maintain your code.

Emotion Includes TypeScript Definitions for @emotion/react and @emotion/styled

Emotion is a popular CSS-in-JS library that includes TypeScript definitions for @emotion/react and @emotion/styled . Emotion allows you to write CSS styles in your components using a JavaScript object or template literals.

Here is an example of using Emotion in a React component:

import React from 'react'; import styled from '@emotion/styled';const Wrapper = styled.div` display: flex; flex-direction: column; justify-content: center; align-items: center; `;const Title = styled.h1` font-size: 36px; color: #333; `;interface AppProps < title: string; >const App: React.FC = () => < return ( ); >;export default App; 

Using Emotion with TypeScript ensures that your styles are correctly typed and that you can catch any errors at compile time.

To Style an Element with the Inline Style Attribute, the Value Must Be a JavaScript Object

When using the inline style attribute to add styles to your React components using TypeScript, the value must be a JavaScript object.

Here is an example of using the inline style attribute in a React component:

import React from 'react';interface ButtonProps < label: string; color: string; >const Button: React.FC = () => < return >> ; >;export default Button; 

Using a JavaScript object ensures that your inline styles are correctly typed and that you can catch any errors at compile time.

Use the background-color Property Instead of backgroundColor

When adding styles to your React components using TypeScript, it is important to use the correct property names. For example, use background-color instead of backgroundColor .

Here is an example of using the background-color property in a React component:

import React from 'react';interface CardProps < title: string; description: string; backgroundColor: string; >const Card: React.FC = () => < return ( >> ); >;export default Card; 

Using the correct property names ensures that your styles are correctly applied to your React components.

To Set CSS Styles on an Element in TypeScript, Select the Specific Element and Set Properties on Its Style Object

When setting CSS styles on an element in TypeScript, it is important to select the specific element and set properties on its style object.

Here is an example of setting CSS styles on an element in TypeScript:

import React, from 'react';interface InputProps < label: string; >const Input: React.FC = () => < const inputRef = useRef(null); useEffect(() => < if (inputRef.current) < inputRef.current.style.backgroundColor = '#F5FCFF'; inputRef.current.style.border = '1px solid #333333'; inputRef.current.style.padding = '10px'; >>, []); return ( <>  /> ); >;export default Input; 

Selecting the specific element and setting properties on its style object ensures that your styles are correctly applied to your React components.

Important Points

JSX Modes in TypeScript

When working with TypeScript and React, there are two modes for JSX: preserve and react . The preserve mode keeps the JSX as-is and lets the downstream tools handle it. The react mode emits React.createElement, which is required for JSX to work.

Common Problems with Inline Styles in TypeScript

When working with inline styles in TypeScript, there are some common problems you may encounter, such as not being able to access the style property of an element or not being able to set certain style properties. To solve these problems, use the correct TypeScript types and select the specific element to set the properties on its style object.

Introduction to JSS and TypeScript in React Apps

JSS is a CSS-in-JS library that allows you to write styles in JavaScript. When using JSS with TypeScript in React apps, you can use the createUseStyles hook to create styles and the ThemeProvider to set themes.

@types/react-with-styles is a TypeScript library that provides type definitions for react-with-styles , which is a CSS-in-JS library for React. Using @types/react-with-styles ensures that your styles are correctly typed and that you can catch any errors at compile time.

Introduction to StyledComponent in React

StyledComponent is a CSS-in-JS library for React that allows you to write styles in your components using a tagged template literal . Using StyledComponent with TypeScript ensures that your styles are correctly typed and that you can catch any errors at compile time.

Benefits of Using the StyleSheet Module for CSS Styling

Using the StyleSheet module for css styling in react ensures that your styles are organized and makes it easier to maintain your code. The StyleSheet module also allows you to define styles in a separate file and import them into your React components.

Explanation of Using the style Prop with Plain Old JavaScript Object or an Array of Styles

When using the style prop with plain old JavaScript object or an array of styles in React, the styles are merged together to form a single style object. This allows you to apply multiple styles to your React components.
