Dynamic Routing Basics

Next.js offers strong capabilities for developing dynamic routes that make navigation in sites easier for developers. Understanding routing in this library forms the core of developing adaptive and flexible applications.

How does Next.js routing work?

In Next.js, routes are self-created based on how files are structured in the pages directory. Each file under this directory is a route. This makes development easier:

Static routes: For example, the file about.js within the pages directory will be available at /about.
Dynamic routes: To specify a route with dynamic parameters, you can enclose them in square brackets. For example, the file [id].js within the pages/posts directory specifies a route /posts/1, /posts/2 and so on where id is a dynamic segment.

Examples of static and dynamic routes

Let’s take some examples to understand better:

Static routes:

pages/index.js is the home route that will be available on “/”.
pages/contact.js – The contact page is available under “/contact”.

Dynamic routes:

pages/products/[productId]. js is the route to see an individual product page. For each unique product ID you don’t have to create a unique file; Next.js will automatically adjust based on your configuration.
pages/users/[username].js is another route for looking up user information that can be accessed through /users/ivan, /users/maria etc.

It must be mentioned that making use of dynamic routing allows someone to have the ability to devise a richer and personalized user experience, as one can access suitable content with relative ease.

Benefits of using dynamic routing in Next.js

With the use of dynamic routing, you have the following notable advantages:

Flexibility: Allows you to specify routes with any number of parameters, making it much easier to work on multi-level pages.
Convenience: All of the routing code is within the project, and therefore it’s easier to maintain and extend.
Easy integration: Dynamic routes easily integrate with the API for file uploads – the ideal solution for SPA applications.

In Next.js dynamic routing not only becomes a tool, but an important part of the development process making it easy to dramatically accelerate the process of creating multi-functional applications with modern user interface. Having adequate knowledge about routing principles, you will be able to create applications that not only look visually appealing but also have high efficiency and speed.

SSR and SSG: When to use?

One of the key decisions when developing with Next.js is between server rendering (SSR) and static rendering (SSG). Both approaches have advantages and disadvantages, and getting the right choice can make a significant difference to the performance of your web application and SEO configurations.

Server Rendering (SSR)

Server rendering is the server-side rendering of HTML with each user request. This assists you in fetching updated data on page loading. Remember the major benefits and drawbacks of SSR:

Benefits:

Relevance of data: With each page load, the user gets the most recent data.
SEO assistance: Server-side pages are more quickly indexed by search engines, enhancing visibility within the search results.

Drawbacks:

Server burden: A request necessitates a page generation server, which results in an augmentation of the response time.
Difficulty of caching: In order to optimize the effort, one has to implement successful caching techniques.

Static rendering (SSG)

Static rendering, though, pre-renders HTML in advance during application build. This is wonderful for content that is not frequently changing. These are the most important features of SSG:

Advantages:

Load speed: Static pages have a faster load time because they are pre-rendered.
Efficient caching: Pages can be cached well on the CDN side, reducing server load.

Disadvantages:

Data is outdated: If after compilation the data has been altered, a new project compilation will be necessary to refresh it.
Inadequate for any kind of application: SSG is more apt to employ where content remains minimal, like in blogs or documentation.

How to select the best method?

While deciding between SSR and SSG, there are some factors to take into consideration:

Content type: If your app is refreshing data very frequently (e.g., news websites), it’s more suitable to opt for SSR. If data is not changing, SSG will be the ideal choice.
Performance requirements: If boot speed is extremely critical, SSG will be a good choice due to its architecture.
Maintenance costs: SSR can consume more server resources, and thus the cost will be higher, especially with multiple users.

Finally, whether or not to use SSR or SSG will be based on your content and performance requirements. The right approach will improve the user experience, in addition to optimizing the SEO value of your site.

Dynamic SEO-Friendly Websites architecture

Creating a web application is not only a question of design and functionality, but also an important aspect of SEO. It should be remembered that even the most innovative site can not achieve success without properly tuned search optimization. In this context, Next.js provides powerful tools to maximize the visibility of your site in search engines. Consider key points:

Pre-rendering: Next.js supports two types of rendering – server (SSR) and static (SSG). This allows you to create pages that can be indexed by search engines, providing better visibility for your users.
Easy to tag: With the built-in <Head> feature, you can easily add tags such as headings, descriptions and keywords for each page. This is critical to improving your search performance.
URL optimization: Use clean and clear URLs with relevant keywords. Next.js supports dynamic routing, which makes it easy to create logical and SEO-friendly URLs.
Adaptive design: Since most users now access websites through mobile devices, Next.js allows you to make your applications fully adaptive, which is certainly a plus in the eyes of search engines.
Great content management: Next.js is well integrated with various CMS and API, which makes it easy to update the content on your site without any negative impact on SEO.

Optimize site performance

Celadonsoft: Performance of the site is one of the main factors that affects not only the user experience, but also SEO. Digital research shows that even small delays in loading pages can lead to a significant increase in the failure rate. Consider some best responsive practices to optimize your application for Next.js:

Caching: Use the built-in Next.js caching mechanisms, such as static resource caching and server caches, to speed up page loading.
Image Optimization: Next.js’s image optimization options allow you to upload images in the right size and format. Use the <Image> component to automatically optimize images and improve boot speeds.
Microservices and API: Instead of uploading all the data to the client, use server functions to get data from the API. This helps to reduce the size of data transferred and speeds up loading.
Lazy loading: Enable lazy loading (LAG) for non-essential components and images. This means that part of the content will be downloaded only as needed, which will significantly speed up the first render.
Performance analysis: Regularly test your site with tools like Lighthouse to identify bottlenecks and optimize the performance of your site.

Following these recommendations, you will be able to create not only a Dynamic SEO-Friendly Websites, but also high-performance site based on Next.js, which effectively attracts and retains users.

Conclusion: Pros and Cons of using Next.js

Next.js is becoming an increasingly popular tool among web developers, and this is no accident. However, like any solution, it has its advantages and disadvantages.
