1 00:00:00,150 --> 00:00:07,440 All right, and the last method I would like to cover is a delete method, so below the put method, 2 00:00:07,590 --> 00:00:11,220 below the modifier option, I'm going to go with AB. 3 00:00:12,030 --> 00:00:14,520 The method is delete again. 4 00:00:14,520 --> 00:00:23,580 The convention, if you have a list, is going with a list, YORO, and then add that specific idy because 5 00:00:23,580 --> 00:00:27,180 the setup is going to be extremely similar to a put one. 6 00:00:27,510 --> 00:00:32,220 Now the only difference is, is going to be that of course in this case when we're deleting, we're 7 00:00:32,220 --> 00:00:35,190 not expecting anything in the body if. 8 00:00:36,050 --> 00:00:43,880 The user hits the URL, for example, API people, and then one, we just removed that sucker from our 9 00:00:43,880 --> 00:00:44,240 list. 10 00:00:44,400 --> 00:00:44,900 That's it. 11 00:00:45,470 --> 00:00:48,980 So let's go down where we have app lead. 12 00:00:49,250 --> 00:00:54,830 And again, the path is following where we go with API and then people. 13 00:00:55,220 --> 00:01:01,310 And again, let me stress one more time something where these routes are different. 14 00:01:02,400 --> 00:01:11,010 When we talk about Abdulbaset and API people, when we talk about app that post and API people, or 15 00:01:11,010 --> 00:01:18,420 even if we talk about app that put an app that delete just because the path is the same, since the 16 00:01:18,420 --> 00:01:21,450 method is different, these are different requests. 17 00:01:21,660 --> 00:01:22,790 That is crucial. 18 00:01:23,220 --> 00:01:29,220 Please don't think that just because you have a different method, you have to set up a whole new path. 19 00:01:29,430 --> 00:01:32,570 No, you can have the same value for the path. 20 00:01:32,580 --> 00:01:36,580 If the method is different, that is totally different request. 21 00:01:36,930 --> 00:01:39,360 So let's go here again with our callback function. 22 00:01:39,360 --> 00:01:41,370 We should already be comfortable with this one. 23 00:01:41,580 --> 00:01:47,670 We have Barack and Raz, and in this case, I'm not going to the structure of the idea from the problems. 24 00:01:47,860 --> 00:01:53,950 I just want to showcase that we also have this option of accessing the programs directly. 25 00:01:54,330 --> 00:01:59,490 So first, again, I want to look for the person, then we'll send back of this response. 26 00:01:59,500 --> 00:02:04,470 And yes, oftentimes put and delete are going to be extremely similar. 27 00:02:04,860 --> 00:02:10,710 And that if the person does exist, then, of course, I'll just filter out the array and remove that 28 00:02:10,710 --> 00:02:18,090 person from the array, since, again, the whole point of this request is to remove that person from 29 00:02:18,090 --> 00:02:18,570 the array. 30 00:02:18,990 --> 00:02:26,550 So in this case, I can actually copy and paste and I know some of you might find that annoying. 31 00:02:26,790 --> 00:02:32,070 But at the same time, we do need to speed this up and start working with a database. 32 00:02:32,400 --> 00:02:34,080 So hopefully you can forgive me. 33 00:02:34,260 --> 00:02:40,740 I'm just going to grab everything, starting with the person all the way until the end of our error 34 00:02:40,800 --> 00:02:44,700 response before or for the let's scroll down copy and paste. 35 00:02:44,940 --> 00:02:46,800 And this is what we're trying to do. 36 00:02:47,040 --> 00:02:53,160 So I'm trying to find a person whose ID matches that in the primes. 37 00:02:53,400 --> 00:02:57,760 And of course, in this case, I haven't structured the ID right. 38 00:02:57,990 --> 00:03:05,220 So I just need changes around where I go with Iraq and then programs and the ID again, the setup is 39 00:03:05,220 --> 00:03:06,040 exactly the same. 40 00:03:06,060 --> 00:03:13,500 The difference is that I'm directly accessing the program's object and if the person doesn't exist, 41 00:03:13,830 --> 00:03:16,290 then we send back the for four. 42 00:03:16,590 --> 00:03:18,450 So let's try this response. 43 00:03:19,320 --> 00:03:27,080 I'm going to go back to my postman again, the oppressed people, but we need to change the method. 44 00:03:27,180 --> 00:03:27,360 Right. 45 00:03:27,570 --> 00:03:33,540 So now I would want to delete and since I want to test out the error and as a sign up, you can send 46 00:03:33,540 --> 00:03:34,900 the body, doesn't really matter. 47 00:03:35,250 --> 00:03:39,560 We're not handling that on the server anyway, so it's really irrelevant. 48 00:03:39,780 --> 00:03:43,470 But since I want to test out the error, I'm going to go with ABC. 49 00:03:43,710 --> 00:03:48,600 So again, the path is localhost API people and then ABC. 50 00:03:48,780 --> 00:03:51,860 And if everything is correct, I should see the error. 51 00:03:52,080 --> 00:03:53,160 And of course there is. 52 00:03:53,430 --> 00:03:56,660 But something tells me that this is a different error. 53 00:03:56,970 --> 00:03:58,780 So let's go back and check it out. 54 00:03:59,070 --> 00:04:05,460 And of course, the issue is following notice here in the U.S. on how I'm accessing the area now. 55 00:04:05,460 --> 00:04:06,700 Of course, I have in the structure. 56 00:04:06,700 --> 00:04:11,130 And right in this case, I went with Rick programs and then Deery. 57 00:04:11,370 --> 00:04:17,339 So I'm going to go with Iraq programs and let's save it and let's try one more time. 58 00:04:17,640 --> 00:04:24,810 Again, I'm looking for a person whose ID doesn't exist, so I'm going to get the error and there is 59 00:04:25,020 --> 00:04:27,690 I have success, false. 60 00:04:28,050 --> 00:04:35,100 And as far as the message, no person with ID of A, B, C, so I was looking for the person. 61 00:04:36,070 --> 00:04:43,410 With I.D., that's not in my area, so that's why, of course, I got back the response. 62 00:04:43,690 --> 00:04:50,920 So now I'm going to go back to our delete request and here I just want to filter out the error and the 63 00:04:50,920 --> 00:04:53,200 way we're going to do that, I'm going to go with CONSED. 64 00:04:53,200 --> 00:04:58,470 New people is equal to people that filter. 65 00:04:58,870 --> 00:05:01,000 That's my Meyera and I'm just filtering. 66 00:05:01,000 --> 00:05:03,730 It will pass in my callback function. 67 00:05:05,140 --> 00:05:14,560 I'll reference each object where the person parameter and I'll just say if person I.D. does not match 68 00:05:14,920 --> 00:05:19,600 the ID found in Iraq, dot primes then return that person. 69 00:05:20,260 --> 00:05:23,020 If it does match, then it's not going to be included. 70 00:05:23,050 --> 00:05:28,990 That's why we go with my point and remember that we still get our idea as a string. 71 00:05:28,990 --> 00:05:33,970 So we must do the number one first and then only we go with primes. 72 00:05:34,240 --> 00:05:36,620 And so that's our new. 73 00:05:36,700 --> 00:05:42,840 All right, without that specific person whose ID matched the one in primes. 74 00:05:43,120 --> 00:05:51,190 So now, of course, let's just go with our return return, whereas that status here and this is going 75 00:05:51,190 --> 00:05:56,590 to be two hundred, of course, and I'm going to go to Jason and we'll set up our object. 76 00:05:56,770 --> 00:06:02,060 Success is true and I'll send back the new people. 77 00:06:02,090 --> 00:06:02,330 Right. 78 00:06:02,620 --> 00:06:07,270 So we're going to go with data and new people, let's say it. 79 00:06:08,140 --> 00:06:16,010 And let me start out in the postman, where, of course, now I'm going to go with ID that is in the 80 00:06:16,010 --> 00:06:17,770 area and I was going to be number one. 81 00:06:18,010 --> 00:06:25,660 So if I send notice how it is irrelevant if I send the body again because I'm not handling that on the 82 00:06:25,660 --> 00:06:26,620 server anyway. 83 00:06:26,920 --> 00:06:34,630 But if I take a look at my data, well, person with I.D. number one, John is missing. 84 00:06:34,630 --> 00:06:34,950 Why? 85 00:06:35,230 --> 00:06:39,550 Well, because his ID matched to the one that I passed in the prompts. 86 00:06:39,880 --> 00:06:42,840 So now, of course, he was removed from the area. 87 00:06:43,060 --> 00:06:48,880 So if I go with five, same deal now the John is back here because again, we're not persisting there, 88 00:06:49,270 --> 00:06:55,900 but the person with ID of five has been removed from the array. 89 00:06:56,410 --> 00:07:03,760 Hopefully this gives you a good understanding how we use other methods as well, not just get and why 90 00:07:03,940 --> 00:07:08,020 we go with Postman instead of setting up the front then. 91 00:07:08,380 --> 00:07:15,550 But before we cover routine express, let me just stress something that yes, while we're developing 92 00:07:15,550 --> 00:07:21,730 our server course, we'll use Postman because you can clearly see how much faster errors are set up 93 00:07:21,730 --> 00:07:23,890 throughout and I quickly test it. 94 00:07:24,340 --> 00:07:29,380 Otherwise, if I were to have to build a front end for every route that I'm creating, I mean, the 95 00:07:29,380 --> 00:07:32,290 process would be just very, very long. 96 00:07:32,590 --> 00:07:41,770 But the end of the day, when you set up the API, the expectation is that there is going to be someone 97 00:07:41,770 --> 00:07:45,250 who is using that data now that could be on your own server. 98 00:07:45,260 --> 00:07:51,310 So, for example, if you're building a full stack application with MERN, that's one of the options 99 00:07:51,520 --> 00:07:53,610 that could be decoupled application. 100 00:07:53,620 --> 00:08:02,110 Remember how I showed you a example where I have the API on my server, but then there is a react application 101 00:08:02,110 --> 00:08:06,040 that uses it doesn't mean that you have to build that front end application yourself. 102 00:08:06,520 --> 00:08:11,170 Just be mindful that the whole idea of setting up the API. 103 00:08:12,090 --> 00:08:15,310 Is that someone is going to be using that data? 104 00:08:15,870 --> 00:08:16,400 That's it. 105 00:08:16,410 --> 00:08:17,850 That's all I want to say. 106 00:08:18,090 --> 00:08:22,440 And of course, we can talk about router in Xpress.
