Nextjs styled components

nextjs styled components

Next.js is an open-source React framework that enables developers to build server-rendered and statically generated applications with ease. By embracing a hybrid model, Next.js allows for optimized performance and SEO benefits, making it a favorite among web developers. Frameworks like Next.js provide developers with a structured environment to build web applications, offering built-in solutions for routing, server-side rendering, static site generation, and more. This contrasts with libraries, which typically provide specific functionality without dictating the overall architecture of your application. Next.js is distinctly a framework, as it provides a comprehensive toolkit for developing robust applications efficiently.

As you venture into the world of Next.js, you'll find it facilitates a variety of approaches to building user interfaces. One vitally important aspect of modern web development is styling, and that’s where styled-components come into play. Styled-components is a popular CSS-in-JS library that allows you to use component-level styles in your application. It leverages tagged template literals to style your components, creating dynamically scoped styles that are tied directly to your components. This encapsulation means that your styles won't clash with global styles, leading to cleaner and more maintainable codebases.

Getting Started with Next.js and Styled-components

To integrate styled-components into a Next.js application, you need to follow a few straightforward steps. First, you should install styled-components along with its TypeScript types if you're using TypeScript. You can do this by running the following command in your terminal:

npm install styled-components
npm install --save-dev @types/styled-components

Next, you'll want to set up your application to support Server-Side Rendering (SSR) with styled-components. To achieve this, you can create a custom _document.js file in the pages directory if you haven't done so already.

Here's an example of how to set up a custom _document.js for styled-components:

// pages/_document.js
import Document, { Html, Head, Main, NextScript } from 'next/document';
import { ServerStyleSheet } from 'styled-components';

export default class MyDocument extends Document {
  static async getInitialProps(ctx) {
    const sheet = new ServerStyleSheet();
    const originalRenderPage = ctx.renderPage;

    ctx.renderPage = () =>
      originalRenderPage({
        enhanceApp: (App) => (props) => sheet.collectStyles(<App {...props} />),
      });

    const initialProps = await Document.getInitialProps(ctx);
    return {
      ...initialProps,
      styles: [
        <>
          {initialProps.styles}
          {sheet.getStyleElement()}
        </>
      ],
    };
  }

  render() {
    return (
      <Html>
        <Head>
          {/* You can add global CSS links or fonts here */}
        </Head>
        <body>
          <Main />
          <NextScript />
        </body>
      </Html>
    );
  }
}

Creating Styled Components

Now that your setup is complete, you can start creating styled components in your application. For example:

// components/Button.js
import styled from 'styled-components';

const Button = styled.button`
  background-color: #0070f3;
  color: white;
  border: none;
  border-radius: 5px;
  padding: 10px 20px;
  cursor: pointer;

  &:hover {
    background-color: #005bb5;
  }
`;

export default Button;

You can then import and use your styled component anywhere in your pages or other components:

// pages/index.js
import Button from '../components/Button';

const Home = () => {
  return (
    <div>
      <h1>Welcome to My Next.js App!</h1>
      <Button>Click Me</Button>
    </div>
  );
};

export default Home;

Conclusion

Styled-components provide a powerful way to manage styles in your Next.js applications, combining the advantages of JavaScript and CSS in a seamless manner. By leveraging the capabilities of both Next.js and styled-components, you can craft highly responsive and visually intriguing web applications.
