Next.js - Overview
By using Next.js, you can create robust react based application quite easily and test them. Next.js is created by Vercel, which is a cloud based platform to help the developer to develop application, deploy and scale-up the applications as well.
What is Next.js?
Next.js is React Based framework with server side rendering capability. It is very fast and SEO friendly. Next.js comes with a lot of advantages that React was lacking.
Advantages of Next.js over ReactJS
- Hot Code Reload Next.js server detects modified files and reloads them automatically.
- Automatic Routing: No need to configure any url for routing. files are to be placed in pages folder. All urls will be mapped to file system. Customization can be done.
- Component specific styles: The styled-jsx provides support for global as well as component specific styles.
- Server side rendering: React components are pre-rendered on server hence loads faster on client.
- Node Ecosystem: Next.js being react based gels well with Node ecosystem.
- Automatic code split: Next.js renders pages with libraries they need. Next.js instead of creating a single large JavaScript file, creates multiples resources. When a page is loaded, only required JavaScript page is loaded with it.
- Prefetch: Next.js provides Link component which is used to link multiple components supports a prefetch property to prefetch page resources in background.
- Dynamic Components: Next.js allows to import JavaScript modules and React Components dynamically.
