  • React server components are a new architecture introduced by the react team and quickly adopted by next shares, dividing components into server and client types.
  • By default, next treats all components as server components, allowing them to perform server-side tasks like reading files or fetching data directly from a database.
  • To create a client component, developers need to add the use client directive at the top of the component file, enabling the use of hooks and interaction handling.

before we dive into routing let's cover a fundamental concept that will help us better understand how routing Works in X shares that concept is react server components or RSC for short react server components is a new architecture that was introduced by the react team and quickly adopted by next shares this architecture introduces a new approach to creating react components by dividing them into two distinct types server components and client components we will

explore these component types in more detail as we move forward but for now let's focus on a few key points by default NEX treats all components as server components these components can perform server side tasks like reading files or fetching data directly from a database the trade-off is that they can't use react hooks or handle user interactions if you want to create a client component you will need to add the use client directive at the top of

your component file while client components can't perform Ser side tasks like reading files they can use Hooks and handle interactions think of client components as the traditional react components you're already familiar with from previous versions of react as we get into routing you will see practical examples of both component types we will work with several components that wait for certain operations to complete before rendering content and we will use

client components to take advantage of hooks from the routing module having this basic understanding of server and client components will really help you grasp the r in Concepts better if none of this makes sense right now don't worry we will cover everything about react server components in much more detail later in the course all right with this Foundation let's jump into routing in
