![]() ![]() ![]() This is a big shift from traditional React components that run both on the server and on the client. Next.js, with its new app directory released in Next.js 13, fully embraced Server Components by making them the default type components. Server Components are a new type of React components that run on the server and return compiled JSX that is sent to the client. not found pages are defined as not-found.tsx.loading states are defined as loading.tsx.What does this mean? From now on, we can create various types of components in the app directory using a specific filename convention specific to Next.js: This is a big improvement over the current routing system, which requires us to use a specific directory structure to define pages, API handlers, and so on. Using conventional filenames, we can add various types of components in the app directory. We introduce Server Actions in this tutorial, but we cover them in detail in a separate article, linked at the end of this tutorial. Server actions are useful for submitting forms, execute server-side logic, and redirect the user to a new page.Īdditionally, server actions offer us the ability to revalidate data fetched from Server Components, eliminating the need for complex client-side state management as a result of data mutation (such as updating a Redux store). Server actions are useful for executing server-side logic, such as sending emails, or updating a database. Still in alpha, Server Actions are a new way to execute functions on the server, instead of wiring them through an API handler. ![]() In fact, with the new App Router, we can fetch data in parallel, and pass it to the page component: this is a substantial performance improvement over the current routing system. Layouts also solve the waterfall problem, which is a common issue with the current Next.js routing system. Next.js Layouts are not only useful for displaying a common UI across pages, but also to reuse logic and data fetching across pages. Powered by Server Components, layouts are foundational components that wrap pages. Server Components are the default component type in the new app directory. Server Components are useful for rendering the skeleton of a page, fetching data from the server in parallel, and passing it to the "client components". The biggest change in the new App Router is the introduction of Server Components, a new type of React components that run on the server and return compiled JSX that is sent to the client. The new app directory brings many improvements to the existing pages directory, and it's the new default way to write Next.js apps, after a period of experimental releases. In many ways, this new routing system is a complete rewrite of the previous one, and fundamentally changes the way we will write Next.js applications. Next.js 13 is a major release of the most popular React framework: in fact, it ships with a new routing system, also called App Router. Hi and welcome! In this tutorial, we'll learn how to use Next.js 13 with server components and the app directory. ![]()
