From the next docs:
Server Components allow developers to better leverage server infrastructure. For example, you can move data fetching to the server, closer to your database, and keep large dependencies that previously would impact the client JavaScript bundle size on the server, leading to improved performance. Server Components make writing a React application feel similar to PHP or Ruby on Rails, but with the power and flexibility of React and the components model for templating UI.
What is an example of a large dependency that will not be on the client?
