Next.js has quickly become one of the most popular React frameworks for building production web applications. Here are some pro tips and techniques to level up your Next.js development skills.
Leveraging Built-in Routing
Next.js offers file-system based routing by default. Some best practices are:
Place pages in the
pages
folder to create routes. For example,pages/about.js
->/about
Use dynamic routes like
pages/[slug].js
to match parameters.Split larger page components into smaller reusable components in the
components
folder.
Static Site Generation (SSG)
Next.js allows generating static websites at build time for blazing fast performance.
Use
getStaticProps
andgetStaticPaths
in page components to fetch data and render HTML.Statically generate listing pages like blogs, news while using SSR for forms.
Use
revalidate
option to incrementally update static pages.
Server Side Rendering (SSR)
Next.js pre-renders pages on each request for faster initial page loads.
Use
getServerSideProps
to fetch and render data on the server-side.Make sure to optimize queries and limit DB calls in
getServerSideProps
.Use SSG and SSR together to get best of both approaches.
Optimization Techniques
Some ways to optimize Next.js apps:
Use
next/image
for optimized image loading and resizing.Add
next-sitemap
andnext-seo
for better SEO.Use
next-bundles
to analyze code splitting and bundles.Enable compression, etags, immutable headers.
Use API routes to handle data fetching.
With these techniques, you can build high-performance Next.js apps following best practices. Let me know what other tips you have!
