Integrating Theming into Design Systems

2.1 Definitions

• Design System: A collection of reusable components guided by clear standards.
• Theming: The process of changing the visual appearance of components based on predefined styles.
• Component-Driven Development: A methodology that emphasizes building applications using isolated components.

2.2 Importance of Theming

Improves user experience by providing visual consistency across applications, supporting brand identity, and ensuring better accessibility options.

3.1 Define Theme Structure

Create a theme configuration that outlines the different themes available. Example:

const themes = {
    light: {
        backgroundColor: '#ffffff',
        color: '#333333',
    },
    dark: {
        backgroundColor: '#333333',
        color: '#ffffff',
    },
};
                

3.2 Create Styled Components

Utilize a styling solution (e.g., styled-components) to apply themes dynamically:

import styled from 'styled-components';

const ThemedButton = styled.button`
    background-color: ${(props) => props.theme.backgroundColor};
    color: ${(props) => props.theme.color};
`;
                

3.3 Implement Theme Switching

Provide a mechanism for users to switch themes. This can be achieved using React context or a state management library:

import React, { useState, createContext, useContext } from 'react';

const ThemeContext = createContext();

const ThemeProvider = ({ children }) => {
    const [theme, setTheme] = useState('light');
    
    const toggleTheme = () => {
        setTheme((prevTheme) => (prevTheme === 'light' ? 'dark' : 'light'));
    };

    return (
        
            {children}
        
    );
};

const useTheme = () => useContext(ThemeContext);
