Data fetching in Next JS
There are four ways to fetch data
- on the server, with a `fetch`
- on the server, with third-party libraries
- on the client, with route handlers
- on the client, with third-party libraries
Fetching Data on the server with fetch
Fetching Data on the server with fetch, Next Js extends the native fetch web API to allow you to configure the caching and revalidating behavior for each request on the server. fetch with async / await in server components.
Fetching data on the Server with third-party libraries
In cases where you’re using a third-party library that doesn’t support or expose fetch (for example, a database, CMS, or ORM client), you can configure the caching and revalidating behavior of those requests using the Route Segment Config Option and React’s cache function.
Fetching Data on the Client with Route Handlers
If you need to fetch data in a client component, you can call a Route Handler from the client. Route Handlers execute on the server and return the data to the client. This is useful when you don’t want to expose sensitive information to the client, such as API tokens.
Fetching Data on the Client with third-party libraries
Fetching Data on the Client with third-party libraries using SWR and React Query. These libraries provide their APIs for memoizing requests, caching, revalidating, and mutating data.
Getting Started with Next JS
NextJS is an open-source React framework for building full-stack web applications ( created and maintained by Vercel ). You can use React Components to build user interfaces, and NextJS for additional features and optimizations. It is built on top of Server Components, which allows you to render server-rendered React components to the client. This means your pages can be more interactive and dynamic, while still being fast and performant. One of its notable features is the NextJS App Router, which facilitates routing within your application. This article will dive into NextJS App Router, its components, and implementation, and provide a code example and a brief output.
