1 00:00:02,000 --> 00:00:03,000 Now before we start digging 2 00:00:03,000 --> 00:00:06,000 into the created project and before we start diving 3 00:00:06,000 --> 00:00:09,000 into all these core NextJS features, 4 00:00:09,000 --> 00:00:13,000 I want to come back to this project creation process, 5 00:00:13,000 --> 00:00:16,000 and there to this question here, 6 00:00:16,000 --> 00:00:19,000 whether we want to use the App Router or not. 7 00:00:19,000 --> 00:00:23,000 And here it of course said that it's recommended to use it 8 00:00:23,000 --> 00:00:26,000 but nonetheless, I told you to choose no. 9 00:00:26,000 --> 00:00:30,000 Now this approach where you use the App Router 10 00:00:30,000 --> 00:00:34,000 is an alternative way of building NextJS apps. 11 00:00:34,000 --> 00:00:37,000 An alternative to using the Pages Router, 12 00:00:37,000 --> 00:00:39,000 which is the approach we'll use in this course. 13 00:00:40,000 --> 00:00:43,000 The App Router uses a different project structure, 14 00:00:43,000 --> 00:00:47,000 a different folder structure, and different features. 15 00:00:47,000 --> 00:00:48,000 The problem with it 16 00:00:48,000 --> 00:00:52,000 just is that despite the NextJS page telling you 17 00:00:52,000 --> 00:00:55,000 that it's stable to use now, 18 00:00:55,000 --> 00:00:57,000 crucial features are missing there. 19 00:00:57,000 --> 00:01:00,000 To be precise, this Server Actions feature 20 00:01:00,000 --> 00:01:04,000 is still in Alpha at this point of time. 21 00:01:04,000 --> 00:01:08,000 Now, Server Actions is a part of this App Router feature 22 00:01:08,000 --> 00:01:11,000 even though it's not clearly stated here, 23 00:01:11,000 --> 00:01:13,000 but it is crucial for using the App Router 24 00:01:13,000 --> 00:01:16,000 because this Server Actions feature 25 00:01:16,000 --> 00:01:18,000 is a feature that will allow you 26 00:01:18,000 --> 00:01:22,000 to basically handle POST, PUT, PATCH, 27 00:01:22,000 --> 00:01:26,000 basically all non-GET requests in your NextJS app. 28 00:01:26,000 --> 00:01:31,000 So if you wanna build a NextJS app where data can change, 29 00:01:31,000 --> 00:01:34,000 where users can submit forms, for example, 30 00:01:34,000 --> 00:01:37,000 you will need these Server Actions 31 00:01:37,000 --> 00:01:40,000 to handle these changes on the backend. 32 00:01:40,000 --> 00:01:43,000 Right now, this feature is not final yet though, 33 00:01:43,000 --> 00:01:45,000 and therefore likely to change 34 00:01:45,000 --> 00:01:47,000 and likely to contain bugs and errors, 35 00:01:47,000 --> 00:01:50,000 and it's definitely not recommended for production yet. 36 00:01:50,000 --> 00:01:54,000 Therefore, at the moment, with this App Router, 37 00:01:54,000 --> 00:01:56,000 you can only build basic websites 38 00:01:56,000 --> 00:01:59,000 that don't need to handle form submissions and so on. 39 00:01:59,000 --> 00:02:02,000 That's why in the official docs for the App Router, 40 00:02:02,000 --> 00:02:05,000 you also find no entry for manipulating data, 41 00:02:05,000 --> 00:02:07,000 just for data fetching. 42 00:02:08,000 --> 00:02:09,000 And because of that, 43 00:02:09,000 --> 00:02:13,000 this course currently does not cover the App Router yet. 44 00:02:13,000 --> 00:02:16,000 This, of course, very likely will change in the future. 45 00:02:16,000 --> 00:02:19,000 I do plan to update this course 46 00:02:19,000 --> 00:02:21,000 and give you this update for free 47 00:02:21,000 --> 00:02:24,000 once this App Router is fully usable. 48 00:02:24,000 --> 00:02:26,000 So once all features you need 49 00:02:26,000 --> 00:02:30,000 to build production-ready apps with the App Router 50 00:02:30,000 --> 00:02:31,000 are available. 51 00:02:31,000 --> 00:02:35,000 But until then, this course will use the Pages Router. 52 00:02:35,000 --> 00:02:37,000 And that's why I recommended 53 00:02:37,000 --> 00:02:40,000 that you should not use Yes here when creating the project 54 00:02:40,000 --> 00:02:45,000 and you were asked to use the App Router, but No instead.
