Glamorous vs styled-components: What are the differences?

# Introduction

Glamorous and styled-components are two popular libraries in the world of styling components in React. In this comparison, we will highlight the key differences between Glamorous and styled-components to help developers make an informed decision on which library to use.

1. **API Design**: Glamorous uses a function-style API approach, where you define your styles as JavaScript objects and pass them to the glamorous component. On the other hand, styled-components use template literals and CSS to define styles within the component itself, providing a more natural way of writing CSS in JavaScript.

2. **Composition**: In Glamorous, you can compose styles by passing functions to the glamorous component, allowing for more dynamic and flexible style composition. However, styled-components take a more straightforward approach of extending components with styled-components and chaining styles together, making it easier for beginners to grasp.

3. **Server-Side Rendering**: styled-components have built-in support for server-side rendering, which makes it easier to render styled components on the server. On the other hand, Glamorous requires you to install an additional package for server-side rendering, adding complexity to the setup process.

4. **Themes and Styling Variables**: styled-components offer built-in theming support with the ThemeProvider component, allowing developers to create a centralized theme object and share it across the application. Glamorous, on the other hand, lacks built-in theming support, which may require developers to implement custom solutions for theming.

5. **Global Styles**: styled-components allow you to define global styles using the `createGlobalStyle` API, making it easy to set global CSS styles for the entire application. Glamorous does not offer built-in support for global styles, requiring developers to use alternative methods for managing global styles.

6. **Community and Adoption**: styled-components have gained widespread adoption in the React community and have a large, active user base contributing to its development and maintenance. While Glamorous is a popular choice for styling components, it may not have the same level of community support and resources as styled-components.

In Summary, Glamorous and styled-components differ in API design, composition, server-side rendering, theming support, global styles, and community adoption, making them suitable for different use cases in React application development.
