Overview:

Integrating Material-UI with Next.js and Styled-Components can often be a daunting task due to the differing style injection methods utilized by each library. However, this example serves as a comprehensive guide to seamlessly combine them. By understanding how these libraries interact, developers can leverage the strengths of both frameworks to create visually appealing and responsive web applications.

What makes this integration particularly interesting is its focus on configurable styles and the structured organization of related files. From global styles to theme overrides, there are clear directives on how to use Styled-Components alongside Material-UI, making it easier for developers to maintain a consistent design throughout their applications.

Features:

• Configurable Styles: Includes two essential style files located in /lib/styles for easy customization of global styles and Material-UI themes.

• Styled-Components Simplified: The API is designed to be straightforward, with much of the setup efficiency handled in /pages/_document.js.

• Material-UI Integration: Focuses on two critical files in the /lib/material-ui directory that facilitate Material-UI functionality within Next.js.

• Higher-Order Component: Utilizes withRoot.js, which serves as a higher-order component to wrap all pages, ensuring Material-UI works properly throughout the application.

• Page Context Management: Implements getPageContext.js for effective page context management, vital for correctly injecting Material-UI styles within a Next.js setup.

• Initial Props Method: The integration takes advantage of the getInitialProps() method, allowing developers to set up global styles and themes effectively.

• Caveats Noted: Alerts developers to potential issues with style overrides due to the order of style injections, emphasizing the necessity of using !important for customizations.
