A developer integrates server actions into a Next.js application to process user sign-up forms. The walkthrough covers creating an asynchronous server-side function, configuring environment variables, implementing form state management, and troubleshooting client-side rendering requirements using the 'use client' directive.

0:00 All right, so next up, we wanna go back to our UI 0:02 and actually update it to 0:04 be able to call our new create user API to actually 0:08 persist users to our database. In my terminal, I have to make sure that I 0:12 have my back end still running as well as our UI with 0:16 our NPM run dev command. So both of these are running, and we can 0:20 access our web server at 0:21 localhost3000/auth/signup. We of course 0:25 have our user creation form. So now after we click Sign Up, I 0:29 wanna submit this form to our back end and actually process 0:32 this user's creation, just like we've done in Postman. 0:36 So using the Next.js app router approach, the way we're going to 0:40 actually submit forms and execute data mutations 0:44 is going to be by using server actions. 0:47 So server actions are asynchronous functions that 0:50 are executed 0:51 on the server. Just like we have server components in 0:54 Next.js, 0:55 server actions are a similar premise where we essentially have logic 0:59 or functions that live on the server side that our client can call 1:03 remotely to execute. However, all of that code will be encapsulated on 1:07 the back end. Now, the benefits of this are gonna be very 1:10 similar to the benefits we already have to server components. 1:14 So that's gonna include moving the actual work of fetching the data to the server, 1:18 which can be taxing for the UI, as well as moving our actual 1:22 server logic closer to the physical data, such as the 1:26 database, which can improve performance. 1:28 We also have the benefits of enhanced security. 1:31 Since our server components aren't accessed by the client, we can store 1:35 sensitive data such as tokens and keys. 1:38 So with these benefits in mind, let's go ahead and see how we can start
