1 00:00:00,210 --> 00:00:07,680 In this video, we are going to create list and delete Q on Amazon space using the Adobe SDK libraries. 2 00:00:07,890 --> 00:00:13,710 So we will create a Node.js application and use SDK libraries to perform these actions. 3 00:00:13,710 --> 00:00:18,960 And we will use these commands which are the create queue command, get queue, command, delete queue, 4 00:00:18,960 --> 00:00:20,400 command and list queue command. 5 00:00:20,400 --> 00:00:22,620 So let's check the SDK documentation. 6 00:00:22,620 --> 00:00:27,930 If you come to client documentation and search for the create queue command, you can come the create 7 00:00:27,930 --> 00:00:33,210 queue command and this command basically perform the creating queue on Amazon environment. 8 00:00:33,300 --> 00:00:39,060 You can scroll down and see the example usage and if we can check the input parameters, we can go to 9 00:00:39,060 --> 00:00:42,720 create queue command input and see the parameters in here. 10 00:00:42,720 --> 00:00:45,660 It is required to queue name attributes and tags. 11 00:00:45,840 --> 00:00:48,930 So for that purpose let's start the implementation. 12 00:00:48,930 --> 00:00:54,300 Please open the Visual Studio code and I have create a separate section and lecture folder. 13 00:00:54,300 --> 00:00:58,470 In here we can see the section 35 and lecture folders. 14 00:00:58,470 --> 00:01:03,660 So in the lecture 293 will be the our main Node.js application. 15 00:01:03,660 --> 00:01:08,820 And during the rest of the videos we will use this lecture folder as a Node.js application to interact 16 00:01:08,820 --> 00:01:09,860 Amazon SDKs. 17 00:01:09,900 --> 00:01:14,790 So you can see the command text file that I'm going to put some comments in here. 18 00:01:14,820 --> 00:01:20,070 We will use these commands when implementing our use cases and we will follow these steps. 19 00:01:20,070 --> 00:01:25,890 We have creating a Node.js application with NPM in command and install required skills package. 20 00:01:25,890 --> 00:01:32,280 And after that we will create a client JavaScript Node.js file to perform client operations interacting 21 00:01:32,280 --> 00:01:33,420 with Amazon SDKs. 22 00:01:33,420 --> 00:01:36,300 So let me start with the NPM command. 23 00:01:36,300 --> 00:01:40,380 Please open the terminal and locate the correct folder structure. 24 00:01:40,380 --> 00:01:45,150 And after that run this command and PM y and hit enter. 25 00:01:45,180 --> 00:01:50,850 This will create a package JSON file for our application and this folder will be our Node.js application. 26 00:01:50,850 --> 00:01:58,140 The first thing we should do that is set the type information as a module in order to gain a script. 27 00:01:58,140 --> 00:02:03,510 Six Standards Please save the package JSON file with the type module information. 28 00:02:03,510 --> 00:02:09,840 And after that, the second thing we should do is install required a basic package, which is the client 29 00:02:10,080 --> 00:02:11,340 case in our case. 30 00:02:11,340 --> 00:02:15,390 So I'm going to copy and paste this NPM, install command and hit enter. 31 00:02:15,570 --> 00:02:23,170 So this will be update or package JSON file and create node modules in order to adding the client space 32 00:02:23,190 --> 00:02:25,260 library classes. 33 00:02:25,260 --> 00:02:27,180 So this takes some time. 34 00:02:27,300 --> 00:02:28,080 Okay. 35 00:02:28,110 --> 00:02:30,480 The installation is successfully finished. 36 00:02:30,510 --> 00:02:35,610 If you open the package JSON file and scroll down, you can see the dependencies added successfully 37 00:02:35,610 --> 00:02:37,710 and no modules are created successfully. 38 00:02:37,740 --> 00:02:43,440 Now we can use this SDK library to interact with the Amazon space. 39 00:02:43,440 --> 00:02:48,270 So in order to do that, let's go back to our commands and see what's the next step. 40 00:02:48,450 --> 00:02:53,460 The next step should be always create a client object which a separate Node.js module. 41 00:02:53,490 --> 00:02:58,410 So it is a best practice to create a separate Node.js module for client object. 42 00:02:58,410 --> 00:03:00,540 So I'm going to create a space client. 43 00:03:00,570 --> 00:03:08,100 Now I can close the terminal and let's go to the folder and create a client JavaScript file. 44 00:03:08,130 --> 00:03:16,200 And we are going to copy and paste this code for creating an X client and using the client library object 45 00:03:16,200 --> 00:03:19,050 from the SDK of the Client SDK. 46 00:03:19,050 --> 00:03:24,780 And this will be exporting our client object to perform the case operations. 47 00:03:24,780 --> 00:03:26,910 We will send command to this client object. 48 00:03:26,910 --> 00:03:32,790 This will be separate Node.js application and now we are ready to perform our business logic which are 49 00:03:32,790 --> 00:03:36,030 the create queue list, queue and delete queue. 50 00:03:36,060 --> 00:03:39,720 We will use this command operation to perform these use cases. 51 00:03:39,720 --> 00:03:42,390 So let's get started for that purpose. 52 00:03:42,390 --> 00:03:47,160 Please open the Visual Studio code and I'm going to create a separate JavaScript file. 53 00:03:47,160 --> 00:03:49,770 For example, create queue dot JavaScript. 54 00:03:49,800 --> 00:03:52,860 This is very similar with the other modules. 55 00:03:52,860 --> 00:03:59,970 So basically we will use create queue command from the client as a basic library and we also import 56 00:03:59,970 --> 00:04:06,000 our client to interrupt our operations and we are using these commands with pacing parameters. 57 00:04:06,000 --> 00:04:07,470 Parameters are in here. 58 00:04:07,500 --> 00:04:08,880 The queue name is important. 59 00:04:08,880 --> 00:04:10,500 We are going to create a new queue. 60 00:04:10,500 --> 00:04:14,370 The name is the queue and we can set the attributes in here. 61 00:04:14,370 --> 00:04:17,010 Basically we set the delay seconds. 62 00:04:17,010 --> 00:04:19,410 This is the number of seconds which delay. 63 00:04:19,410 --> 00:04:21,870 So also message retention period. 64 00:04:21,930 --> 00:04:24,930 This is the number of the number of messages. 65 00:04:24,930 --> 00:04:27,780 Retention period dates values are the default values. 66 00:04:27,780 --> 00:04:29,280 That's why I set the default values. 67 00:04:29,280 --> 00:04:33,510 But we can change the attributes when creating any queue command on the space. 68 00:04:33,510 --> 00:04:36,840 So after that we will have a run method. 69 00:04:36,840 --> 00:04:42,900 This is the single output and we have available client send method that we passing to command and parameters. 70 00:04:42,900 --> 00:04:47,310 So this is the create queue command that we are going to create a queue now. 71 00:04:47,310 --> 00:04:53,070 So appeal is terminal and go to correct location and click the run node. 72 00:04:53,990 --> 00:04:58,640 Bait paid to command, write the note, create Q comment and hit enter. 73 00:04:58,660 --> 00:05:00,580 So this is going to create a queue. 74 00:05:00,610 --> 00:05:05,120 You can see that we got 200 success response and queue in here. 75 00:05:05,140 --> 00:05:07,720 We can copy the queue in some place. 76 00:05:07,720 --> 00:05:14,310 So we will use this queue record after that and and we will verify from the queue on the end of this 77 00:05:14,350 --> 00:05:15,010 management console. 78 00:05:15,010 --> 00:05:18,840 But before that let me copy and paste in in here. 79 00:05:18,850 --> 00:05:26,290 So now let's verify from the measured console to see the Amazon queue is created or not go to SKUs. 80 00:05:26,290 --> 00:05:32,230 So see that we have successfully create a new queue which has given parameters and attributes. 81 00:05:32,230 --> 00:05:35,140 So we basically perform the create queue operation. 82 00:05:35,170 --> 00:05:37,990 Now the second option is listing queue. 83 00:05:38,020 --> 00:05:44,590 So if you come here and create a separate JavaScript file, which is the least queue JavaScript, this 84 00:05:44,590 --> 00:05:45,300 is very similar. 85 00:05:45,310 --> 00:05:50,620 This time we will use list queue command and there is no any parameters required for this command. 86 00:05:50,650 --> 00:05:58,210 This is listing to queue on Amazon has for that purpose and directly run node command for the list queue. 87 00:05:58,240 --> 00:06:06,370 If you run the node list queue and hit enter, this will be listing the old queue URLs in here. 88 00:06:06,370 --> 00:06:09,730 Since we have one queue, you can see the queue in here. 89 00:06:10,000 --> 00:06:13,600 Now we have one more command which is the delayed queue command. 90 00:06:13,630 --> 00:06:18,180 You can go to the documentation and see the delayed queue command in the commands. 91 00:06:18,190 --> 00:06:24,850 If you search for the delayed queue command, if you open this delete queue command, see the example 92 00:06:24,850 --> 00:06:30,670 usage which is the command and this is the input and make sure that you have input parameters including 93 00:06:30,670 --> 00:06:31,570 the queue URL. 94 00:06:31,570 --> 00:06:36,790 So that's why I saved the queue to perform this operation, open the widgets to the code and create 95 00:06:36,790 --> 00:06:39,850 a separate JavaScript file which is the daily queue. 96 00:06:40,060 --> 00:06:47,590 JS So this time I'm going to pass a queue URL, so that's why I'm going to copy this URL and paste in 97 00:06:47,590 --> 00:06:49,690 here and save this file. 98 00:06:49,720 --> 00:06:56,470 So now you can see that we use the queue command with passing to queue in the parameters and using the 99 00:06:56,980 --> 00:06:58,780 client that sent operation. 100 00:06:58,780 --> 00:07:03,010 So let's perform the delayed cooperation with Node Command. 101 00:07:03,010 --> 00:07:08,020 I'm going to write note, delete, queue that JS and hit enter. 102 00:07:08,810 --> 00:07:13,650 See that we have successfully delayed our queue to verify from the console. 103 00:07:13,820 --> 00:07:20,630 Go to the management console and open the Amazon queue and refresh the page and see that our queue is 104 00:07:20,660 --> 00:07:21,860 deleted successfully. 105 00:07:22,130 --> 00:07:29,180 As you can see that we have successfully perform create list and delete Q on Amazon is using the Sdhc.
