Next.js is a React-based web development framework that allows developers to build server-side rendered React applications. It is an open-source framework that is built on top of Node.js, React, and webpack. Next.js offers many features, including automatic code splitting, server-side rendering, automatic static optimization, route prefetching, and more.

Next.js plugins and extensions are packages that can be installed to extend the functionality of a Next.js application. These plugins and extensions can be used to add features such as CSS preprocessing, static asset optimization, and more. They are open-source and can be easily installed using npm.

Using open-source extensions in Next.js applications offers several benefits. Firstly, it can save developers time and effort by allowing them to use pre-existing solutions rather than building everything from scratch. Additionally, using open-source extensions can improve the quality of a project by providing access to code that has been reviewed and improved by the community.

Finally, open-source extensions can provide a way for developers to contribute to the community and give back to the wider development community.

Overall, Next.js plugins and extensions offer a powerful way to extend the functionality of Next.js applications and can provide many benefits for developers and projects.

1- Next.js SEO

Next SEO is a plugin that makes managing your SEO easier in Next.js projects. It is easy to install, and supports OpenGraph, JSON-LD, configure No-index pages, canonical URLs, Alternate URL, No-Follow and more.

NextSeo works by including it on pages where you would like SEO attributes to be added. Once included on the page you pass it a configuration object with the page's SEO properties. This can be dynamically generated at a page level or in some cases your API may return an SEO object.

11- Serverless Next.js Component

This extension allows you to deploy your Next.js apps on AWS Lambda@Edge via Serverless Components.

Included features:

  • Server side rendered pages at the Edge. Pages that need server side compute to render are hosted on Lambda@Edge. The component takes care of all the routing for you, so there is no configuration needed. Because rendering happens at the CloudFront edge locations' latency is very low!
  • API Routes. Similarly to the server side rendered pages, API requests are also served from the CloudFront edge locations using Lambda@Edge.
  • Dynamic pages / route segments.
  • Catch all routes.
  • Automatic prerendering. Statically optimized pages compiled by next are served from CloudFront edge locations with low latency and cost.
  • Client assets. Next.js build assets /_next/* served from CloudFront.
  • User static / public folders. Any of your assets in the static or public folders are uploaded to S3 and served from CloudFront automatically.
  • Opt-in to static generation (SSG) via getStaticProps.
  • Opt-in to server-side rendering (SSR) via getServerSideProps.
  • Statically generate a set of routes from dynamic sources via getStaticPaths.
  • Base path
  • Preview mode
  • Optional catch all routes
  • Redirects.
  • Rewrites.
  • Custom Headers.
  • Image Optimization
  • Next.js 10 Localization.
  • Incremental Static Regeneration.
  • Next.js 12 features

19- MDNEXT

mdnext is an ecosystem of tools to empower working with NextJS + MDX.

The mdnext CLI surfaces a collection officially maintained and community submitted templates to choose from. Once chosen, the project is cloned locally with a clean commit history and you're ready to build your next project.

@mdnext/components delivers accessible (thanks ChakraUI) and extendable components for working with MDX. These include things you've seen like Code components for styling code blocks or Iframes for embedding rich content to MDX

The mdnext template collection are NextJS based projects with opinions around how to style, handle MDX (and other data sources), deliver media, and handle your most usual workflows (ecomm / blogs / product pages).

While there is an officially maintained collection of templates, I was excited to see and share what the community has created. I know there's many different opinions and comfortabilities as a web developer and want our ecosystem to be accessible.

It offers several official and community starters to build your MDNEXT apps.
