0:00 So as we discussed before, the idea of server components in 0:04 Next.js is that we are actually rendering 0:08 and optionally caching our React components on the server 0:12 side and then sending them back to the client. 0:15 So essentially, we're doing the rendering work on the 0:17 server. 0:18 Now, there's several benefits associated with 0:20 this, including 0:22 data fetching closer to our actual data source, 0:26 security by allowing us to keep sensitive data and logic 0:30 such as keys and tokens on the server. 0:33 We have caching because Next.js can actually reuse and 0:37 cache the results of our rendering requests across 0:41 users, and we can also keep JavaScript 0:43 dependencies that would 0:44 bloat our UI on the server. Now, the best part about server components in 0:48 Next.js is that they're opted in by default, 0:52 so we don't need to do anything. We're just gonna start building 0:55 components, and 0:55 they're gonna be rendered on the server to take advantage of these 0:59 benefits. 1:01 Only when we specifically need to opt out to use client components, 1:05 well, we need to do that by, again, using that syntax we saw 1:09 earlier by having the use client syntax to tell 1:13 Next.js to render our component on the UI, 1:17 which is useful in cases where we have components that need a lot of 1:21 interactivity, since that by default, server components can't 1:25 use state effects and event listeners. 1:28 They need to happen on these client components. 1:32 So when we need to opt in to client components, we're gonna use this syntax 1:36 of use client. 1:38 So now that we've discussed the difference between server and client components, 1:41 let's go ahead and get started on building our first route in our application 1:45 to actually authenticate the user. 1:48 I wanna build a login and sign-up form. 1:52 So we know that routing in Next.js is file-based.
