About single page apps & Next JS
What is a single page app
A single page app (SPA) uses dynamic content to rebuild the user interface. Instead of using the traditional method of different web pages. Single page apps benefit from smoother user experiences and reduced server load. However, SPA apps can have SEO issues, since page content is not visible to web crawlers.
What is React
React is a JavaScript library for building user interfaces. Enabling developers to build single page apps. The library allows developers to create reusable UI components, manage the app state, and efficiently update the UI. React uses a virtual DOM, which improves performance.
What is NextJS
NextJS is a popular web development framework built on top of React, Turbopack, and Speedy Web Compiler. Vercel created NextJS with a few unique SEO and performance benefits, including:
- Server-Side Rendering (SSR)
- Static-Site Generation (SSG)
- Built-in Performance Improvements
What is Server-side rendering (SSR)
With SSR a server generates the complete content of a webpage before sending it to the user’s browser. Improving web page loading times by removing the need for additional javascript downaloads and client-rendering processes. A prime choice if search engine optimization (SEO) and page-load speed are important to you.
What is static-site generation (SSG)
The process of creating HTML files for webpages ahead of time. Meaning when a user requests a page, the server can immediately deliver the pre-rendered HTML file. Removing the need to load items to complete loading the page.
What is a component library
A react component library is a collection of user interface (UI) elements. Such as the design of buttons, type, grid, and visual elements. Built to deliver reusable visual elements to build out different projects.
