1 00:00:00,720 --> 00:00:06,540 So before we move on to server side form validation, I do want to take a little pause here and just 2 00:00:06,540 --> 00:00:11,280 implement some refactoring and refactoring just means moving things around inside your project. 3 00:00:12,000 --> 00:00:16,410 So if you look at our project structure right now, we have a command folder that has a web folder that 4 00:00:16,410 --> 00:00:22,200 has the three files that establish our main routine, set up our middleware and our routine, and that's 5 00:00:22,200 --> 00:00:22,620 fine. 6 00:00:22,650 --> 00:00:25,700 That's a conventional way to build a Web application and go. 7 00:00:26,190 --> 00:00:32,580 Then we have this package, this package folder, and inside of that we have config handlers, models 8 00:00:32,580 --> 00:00:33,150 and render. 9 00:00:33,150 --> 00:00:34,980 And that's fine because those are packages. 10 00:00:35,760 --> 00:00:39,540 But conventionally and there is no hard and fast rule for this. 11 00:00:39,540 --> 00:00:46,980 But conventionally, when you set up a project, anything in your package pkg folder is it means something 12 00:00:46,980 --> 00:00:48,390 to people that are looking at your code. 13 00:00:48,390 --> 00:00:54,840 It means these are resources that are completely divorced from the logic of your application and that 14 00:00:54,840 --> 00:00:57,570 I can import into my own application. 15 00:00:57,660 --> 00:00:58,720 And that's not the case here. 16 00:00:59,190 --> 00:01:05,970 So, for example, this config that's only useful in our application, it depends upon a particular 17 00:01:05,970 --> 00:01:06,900 session manager. 18 00:01:06,900 --> 00:01:10,050 It has a structure that's of use to nobody except ourselves. 19 00:01:10,500 --> 00:01:17,310 In the same way, obviously, our handlers are set up specifically for our application and so are our 20 00:01:17,310 --> 00:01:19,030 models and so is our rendering engine. 21 00:01:19,590 --> 00:01:22,350 So what I'm going to do is refactor. 22 00:01:22,350 --> 00:01:28,410 I'm going to create a new directory here right at the root level of my application, and I'm going to 23 00:01:28,410 --> 00:01:29,370 call it internal. 24 00:01:31,230 --> 00:01:34,170 And that is where I'm going to move these packages. 25 00:01:34,380 --> 00:01:38,880 So I'm going to it's going to be I'm going to take advantage of refactoring built into my application. 26 00:01:39,120 --> 00:01:44,760 I'm going to select these three packages and I'm going to move them to internal those four packages, 27 00:01:44,760 --> 00:01:46,440 I guess, and move them to internal. 28 00:01:46,800 --> 00:01:52,590 And a little dialog pops up in my idee that says, are you sure you want to move these specified directories 29 00:01:52,590 --> 00:01:53,640 from there to here? 30 00:01:54,060 --> 00:01:55,710 And I'm going to check this box. 31 00:01:55,710 --> 00:01:59,820 If it's not checked, check her references and that will do some of the heavy lifting for me. 32 00:01:59,820 --> 00:02:00,810 So I'll refactor it. 33 00:02:02,310 --> 00:02:07,950 So when I do that, things are going to break almost certainly if I try to run this application right 34 00:02:07,950 --> 00:02:14,970 now, go run command Web Maime or Stargirl, chances are there's going to be an error. 35 00:02:15,060 --> 00:02:15,560 Maybe not. 36 00:02:15,570 --> 00:02:16,350 We'll find out here. 37 00:02:16,380 --> 00:02:17,280 Look, it just started. 38 00:02:17,370 --> 00:02:18,530 That worked beautifully. 39 00:02:18,540 --> 00:02:18,930 All right? 40 00:02:18,930 --> 00:02:23,130 So I'll stop the application and let's look at some of the things that have changed. 41 00:02:23,640 --> 00:02:24,990 So back to my main package. 42 00:02:24,990 --> 00:02:25,820 Anything changed there? 43 00:02:25,830 --> 00:02:26,340 Yes. 44 00:02:26,370 --> 00:02:30,030 Notice how it changed GitHub, dotcom, teszler bookings. 45 00:02:30,030 --> 00:02:31,650 This used to say pkg. 46 00:02:31,650 --> 00:02:36,300 And if yours doesn't, you need to change it to pkg from pkg to internal. 47 00:02:37,050 --> 00:02:40,950 So change those for us in the Roots folder under the imports. 48 00:02:41,310 --> 00:02:42,000 Same thing. 49 00:02:42,000 --> 00:02:42,780 And went to internal. 50 00:02:42,780 --> 00:02:49,860 And this makes more sense and it makes more sense because these packages are all internal to my application. 51 00:02:50,400 --> 00:02:55,380 Now if I write something and I will later on in the course, probably if I write something that other 52 00:02:55,380 --> 00:02:57,690 people can use, I'll stick that in the package folder. 53 00:02:57,720 --> 00:02:59,160 So that wasn't too hard. 54 00:02:59,610 --> 00:03:03,840 If your idea did not add automatically refactor things for you, just run it. 55 00:03:03,960 --> 00:03:06,600 It'll tell you where the errors are and go change your imports. 56 00:03:06,600 --> 00:03:08,670 And that's pretty much all you have to do. 57 00:03:08,670 --> 00:03:13,320 And that's one of the great advantages of using an integrated development environment like Goaland. 58 00:03:13,320 --> 00:03:20,700 And there's similar functionality in visual studio code or jet brains, intelligence of the public edition 59 00:03:20,940 --> 00:03:22,050 or the community edition. 60 00:03:22,230 --> 00:03:25,650 Most I.D. support refactoring out of the box. 61 00:03:25,680 --> 00:03:31,050 So I'm going to commit these changes and push them up to get so refactored 62 00:03:33,270 --> 00:03:34,800 to use internal. 63 00:03:36,530 --> 00:03:38,930 Packages and push. 64 00:03:42,150 --> 00:03:46,450 And we are good, so I shall commit push and it's all set. 65 00:03:46,950 --> 00:03:52,080 All right, now in the next lecture, we'll move on to doing some server side form validation, which 66 00:03:52,080 --> 00:03:54,210 is utterly critical, as you will see shortly.
