Unlock the Power of Next.js 9.2: A Game-Changer for Developers

The latest version of Next.js has arrived, and it’s packed with exciting new features that are set to revolutionize the way you build web applications. As a React framework for static pages, progressive web apps, mobile web apps, SEO-friendly pages, and server-side rendering, Next.js has already gained massive popularity among developers.

Built-in CSS Support for Global Stylesheets

One of the most significant updates in Next.js 9.2 is the built-in support for global CSS stylesheets. This feature allows you to import CSS files directly into your application, making it easier to manage global styles. By importing your CSS file in the _app.js file, you can ensure that your styles are applied globally across your app.

import '../styles.css';

Plus, with the ability to minify all stylesheets into a single .css file, you can improve performance and reduce conflicts.

CSS Module Support for Component-Level Styles

Another major update is the introduction of CSS module support for component-level styles. This feature enables you to scope CSS locally by classnames, giving you more control over your component-level styling.

/* styles.module.css */
.container {
  padding: 20px;
}

By using the .module.css extension, you can opt-in to CSS modules and achieve scoping or component-level styling. This feature is backward-compatible, so you don’t have to worry about conflicts with existing libraries.

Improved Code Splitting Strategy

Next.js 9.2 also brings an improved code splitting strategy, which allows you to optimize common chunks with multiple files. This new strategy leverages HTTP/2 to deliver a greater number of smaller-sized chunks, resulting in faster load times and improved performance.

module.exports = {
  //...
  optimization: {
    splitChunks: {
      chunks: 'all',
      minSize: 10000,
      minChunks: 1,
      maxAsyncRequests: 30,
      maxInitialRequests: 30,
      enforceSizeThreshold: 50000,
      cacheGroups: {
        vendor: {
          test: /[\\/]node_modules[\\/]/,
          name: 'endors',
          chunks: 'all',
          priority: -10,
          reuseExistingChunk: true,
        },
      },
    },
  },
};

With the ability to create multiple chunks for different purposes, you can fine-tune your application’s performance like never before.

Catch-All Dynamic Routes

[…name] syntax, you can create catch-all routes that match multiple path parts.

import { useRouter } from 'next/router';

function CatchAllRoute() {
  const router = useRouter();
  const { name } = router.query;

  return (

  );
}

export default CatchAllRoute;

This feature is especially useful when working with nested structures defined by a content source, such as a CMS.
