Next.js vs SvelteKit Comparison

Now, we will compare a few of their features, ranging from routing to deployment. By the end of this article, you should be better equipped to choose one for your specific project. Let's get started!

Routing

Routing is a mechanism for mapping URLs to specific components or pages in your application. All two meta-frameworks use file-based routing, the primary method used by all meta-frameworks.

Next.js: It creates files in the pages directory to define your routes; the file name determines the route. A file called pages/about.js, for example, would correspond to the /about route.
SvelteKit: Each file in your application's src/routes directory represents a route. For instance, a file named ´src/routes/about.svelte´ will be mapped to the /about route.

Error Handling

Error handling is an important aspect of web development that can help ensure the robustness and dependability of your application.

Next.js: You can handle errors using the getInitialProps method, which allows you to fetch data and handle errors before rendering the page.
SvelteKit: You can handle errors by using the $error store, a built-in store that tracks errors occurring during page rendering.

API Routing

API routing is a critical component of modern web applications because it allows different systems and services to interact with one another in a standardized manner. This can be used to expose data or functionality to external partners.

Next.js: API routes can be created by creating a file in the ´pages/api´ directory. The following example demonstrates how it is done.

    export default (req, res) => {
      res.status(200).json({ message: 'Hello, world!' });
    };

SvelteKit: API routes are created by placing a file with a specific naming convention in the src/routes directory. The following example demonstrates how it is done.

    // src/routes/posts/[id].json.js
    export function get(req, res) {
      const { id } = req.params;
      res.status(200).json({ id });
    }

Prerending Pages as Static Site Generator(SSG)

By prerendering pages as an SSG, web developers can improve the performance, SEO, and scalability of their web applications, making them more efficient and user-friendly.

Next.js: Next.js prioritizes static content generation at build time and includes a robust data-fetching framework for that purpose.
SvelteKit: SvelteKit focuses on dynamic and real-time content, with a data fetching framework designed for runtime data fetching.

Styling

Regarding styling your web applications, both frameworks provide flexibility and power; which one to use ultimately depends on personal preference and project requirements.

Next.js: Next.js relies more heavily on third-party CSS-in-JS libraries because it does not support importing CSS or SCSS files directly into your components.
SvelteKit: SvelteKit support built-in CSS module support, allowing you to create modular, scoped styles.

Deployment

Next.js and SvelteKit have similar deployment options, but the two frameworks approach deployment differently.

Next.js: Next.js intends to be deployed as a server-rendered application, which typically runs on a Node.js server.
SvelteKit: SvelteKit is designed to be deployed as a static site generator, which means it can be deployed on any web server that can serve static files

Which One Should You Pick?

Choosing a framework depends entirely on you, your team, and the context of your future project. Both frameworks are popular choices for developing web applications, and each has unique benefits and drawbacks.

When Should you Pick Next.js?

Next.js may be a better choice if you (or your team) are already familiar with React and require more control over your application's configuration.
Remember that Next.js is more than just a tool for creating static websites. It is a hybrid framework because static and server-side generated pages are used (or meta-framework). Next.js is an appealing option for content-rich websites with numerous pages (90k+), as it reduces or eliminates the need for upfront construction time.

When Should you Pick SvelteKit?

SvelteKit is a better fit if you (or your team) value simplicity and ease of use. Many of its features, like server-side rendering, automatic code splitting, and dynamic routing, are similar to those of Next.js. SvelteKit is a good option for developers who want to quickly create web applications without a lot of overhead because of its reputation for simplicity and usability.
One significant advantage of using SvelteKit over Next.js is the ability to work with Svelte. According to the survey “State of JavaScript," developer satisfaction with Svelte is higher than with React.

Conclusion
