Routing

The routing system, support nested routing and dynamic route segments. When a file is created inside the /pages directory, it automatically sets it as a route in Next.js.

pages/index.js ==> /

pages/users/index.js ==> /users

pages/users/create.js ==> /users/create

In Remix, it creates automatic routes. However, the files need to be created in the app/routes directory.

app/routes/index.js ==> /

app/routes/users/index.js ==> /users

app/routes/users/create.js ==> /users/create

Remix routing is built on top of the React Router, and it allows you to utilize React Hooks, like useParams and useNavigate. Remix has a built-in support for nested routing with the nested layouts, while Next.js requires manual configurations.

Data Loading

There are several data loading techniques in web applications.

• Server-side rending in the runtime.
• Server-side rending in the build time.
• Client-side rending at runtime.
• A mix of server-side runtime, client-side and server-side build time, and client-side runtime.

In Next.js, we can use all the above techniques with different functionality to export data from a page.

You can use getServerSideProps to load the data on the server-side at runtime while getStaticProps and getStaticPath can be used to load the data from the server-side at build time.

The following example shows how to use getServerSideProps to load data.

export const getServerSideProps = async (
  { 
    params,
    query 
  }
  ) => {

  // get a param from the url 

  const id = params.id 

  // getting data from the url query string 

  const DataLimit = query.DataLimit
  
  return {props: {id, DataLimit}}

};

export default function FirstPage() {

  let {id, DataLimit} = useLoaderData();

  return (

    <div>

      <h1>
        The parameters are: {id}
      </h1>

      <h1>
        The DataLimit url query is: {DataLimit}
      </h1>

     </div>

  ); 

}  
          

In Remix, there are only two methods to load the data. You can use the server-side at runtime and the client-side at runtime to render the data.

You have to export a loader function from a route to load data from the server-side and useFetcher Hook in Remix to load data on the client-side.

import { useLoaderData } from "remix";
export let loader = async ({ 
  params, 
  request 
}) => {
          
// get a param from the page url
          
const id = params.id 
          
// getting data from the url query string 
          
const url = new URL(request.url) 
          
const dataLimit = url.searchParams.get("dataLimit")
          
return {id, dataLimit}
};
          
export default function FirstPage() {
          
let {id, dataLimit} = useLoaderData();
          
return (
          
  <div>
          
    <h1>The parameter is: {id}</h1>
          
    <h2>
      The limit for url query is: {dataLimit}
    </h2>
          
  </div>
          
);
}
          

Next.js supports server-side rendering (SSR), static site generation (SSG ), Incremental site regeneration (ISR), and CSR (client-side rendering). On the other hand, Remix only supports SSR and CSR.

Deployment

Next.js can be installed on any server that can run Node.js by running next build && next start.

It has a built-in support for running in serverless mode when deploying to Vercel, and the Netlify team has written an adaptor for serverless deployment to their service.

The Remix was built to run on any platform and interface with any system. As a result, Remix is a request handler inside an HTTP server, allowing you to utilize any server. When you build a Remix app, you’re asked where you want to deploy it, and you have the following options as of this writing:

• Remix App Server
• Express Server
• Netlify
• Cloudflare Pages
• Vercel
• Fly.io
• Architect (AWS Lambda)

Styling

Remix offers a built-in technique of linking classic CSS style sheets using link tags, while Next.js comes with Styled-JSX as the default CSS in JS solution.

Styled-JSX allows you to style your components with encapsulated and scoped CSS in your Next.js application. You can use <style jsx> tag into the existing React component and define the CSS inside that. Remix uses a simple method to add styles to the page using<link rel ="stylesheet">tag.

When you add the stylesheet link, you can use the links module in Remix routing to export the layout. The code snippet below shows how to use the links function to load the stylesheet in Remix.

 
            export function links() {
              return [{

                rel: "stylesheet",

                href: "https://test.min.css"

              }];
            }

The following example shows how <Links> tag merges the links component in each nested route when rendering the myCart component.

 
            import { Links } from "remix";

            export default function myCart() {
            
            return (
            
              <html>
              
                <head>
              
                  <Links />
              
                  {/* ... */}
              
                </head>
              
                {/* ... */}
              
              </html>
            
            );
            }
