1 00:00:00,270 --> 00:00:05,750 In this video, we are going to be writing an item into the IMDB table. 2 00:00:05,760 --> 00:00:13,530 So we are in the use case three red and white item in the table and we will use put item command in 3 00:00:13,530 --> 00:00:16,380 order to writing item in the existing table. 4 00:00:16,590 --> 00:00:22,500 So before we start, we should check the API SDK reference documentation. 5 00:00:22,500 --> 00:00:28,410 So in here I'm going to search for the food item command, food item command. 6 00:00:28,980 --> 00:00:34,110 If you click the food item command, you can see the details, how we can insert an item into Dynamo 7 00:00:34,170 --> 00:00:38,580 DB table, we can see example usage code in here. 8 00:00:38,580 --> 00:00:41,850 We should import IMDB client and put item command. 9 00:00:41,850 --> 00:00:45,000 So put item command, get some input parameters. 10 00:00:45,000 --> 00:00:49,500 In order to see the parameters, we can click the output item command input. 11 00:00:50,130 --> 00:00:56,070 If you see the put item command properties, you can see there's lots of properties that we can provide. 12 00:00:56,070 --> 00:01:02,190 So the table name is important, we should provide the table name and after that we should add an item 13 00:01:02,190 --> 00:01:03,060 in here. 14 00:01:03,060 --> 00:01:06,510 So item will be insert or dynamic DB table. 15 00:01:06,510 --> 00:01:13,290 If you open the item, you can see the structure of the item, how we can provide these properties into 16 00:01:13,290 --> 00:01:13,980 an item. 17 00:01:13,980 --> 00:01:17,580 So let's implement this code in our visit to the code project. 18 00:01:17,610 --> 00:01:20,460 In order to do that, please open the visual code. 19 00:01:20,460 --> 00:01:26,520 And as you know that I'm going to follow the same folder, which is the all CRUD operations. 20 00:01:26,520 --> 00:01:32,910 So now I have created a new JavaScript file, which is the right item that is in this file. 21 00:01:32,910 --> 00:01:39,170 Basically, we will implement our actual logic to interact the Dynamo DB For that purpose, I have created 22 00:01:39,170 --> 00:01:43,800 a run function and and we call these function in the same file. 23 00:01:43,800 --> 00:01:49,920 And after that we have prepared the parameters to pasting the dynamic DB client object. 24 00:01:49,920 --> 00:01:52,410 And also we need to import statement as well. 25 00:01:52,500 --> 00:01:55,110 So let's start implementation. 26 00:01:55,110 --> 00:02:01,080 Basically, I'm going to write this line of code to perform put data operation. 27 00:02:01,170 --> 00:02:04,560 So if you remove the command part. 28 00:02:04,560 --> 00:02:09,300 So basically as you can see that this time we are using to put item command with sending the Dynamo 29 00:02:09,300 --> 00:02:10,050 DB client. 30 00:02:10,050 --> 00:02:15,990 So we need to import put item command statement into our HDC packets. 31 00:02:15,990 --> 00:02:23,700 So last thing is left for the parameters, how we can add parameters and create items into Dynamo DB 32 00:02:23,730 --> 00:02:27,750 using the boot item command, we should provide the parameters in here. 33 00:02:27,750 --> 00:02:33,150 So basically there are two main parameters when creating an item. 34 00:02:33,600 --> 00:02:36,390 This is the table name and the item parameters. 35 00:02:36,390 --> 00:02:42,390 So a table name is a product that we create in the last video, an item that is going to insert item 36 00:02:42,390 --> 00:02:44,100 into our dynamic DB table. 37 00:02:44,130 --> 00:02:49,530 We should provide the partition key, which is the ID and specify the number format. 38 00:02:49,530 --> 00:02:55,500 And after that I have several attributes that you can add additional attributes in this line of code. 39 00:02:55,500 --> 00:03:02,820 I'm going to add a name and the name is a string and I'm going to add the iPhone X product into number 40 00:03:02,820 --> 00:03:03,870 001. 41 00:03:03,870 --> 00:03:10,920 So here you can find the parameters and this parameter definition to the boot item command and dynamically 42 00:03:10,920 --> 00:03:15,870 be client object sent to our item command to dynamic DB to insert an item. 43 00:03:15,990 --> 00:03:23,640 So please save this file and open the terminal, go to the same directory and run the node command for 44 00:03:23,640 --> 00:03:27,150 the writing and item so not v. 45 00:03:27,150 --> 00:03:29,670 We are going to run node command with the right item. 46 00:03:29,670 --> 00:03:31,410 JS Hit the enter. 47 00:03:32,630 --> 00:03:37,090 So you can see that we have successfully get a 200 response. 48 00:03:37,100 --> 00:03:42,500 That means we have added in inserted successfully item into dynamic TV. 49 00:03:42,530 --> 00:03:44,810 To verify that, please open the. 50 00:03:46,170 --> 00:03:47,410 Edwards management console. 51 00:03:47,430 --> 00:03:48,750 Go to product table. 52 00:03:48,900 --> 00:03:50,660 Click to explore table items. 53 00:03:50,670 --> 00:03:57,600 Run the scan command and see that we have successfully ad ID one and the name is a phone x. 54 00:03:58,370 --> 00:04:06,500 Since we have defined as a number even we give the 001, it takes the one to the ID as a part of product 55 00:04:06,500 --> 00:04:07,040 table. 56 00:04:07,340 --> 00:04:12,290 So as you can see that we have successfully write item in order in the table. 57 00:04:12,320 --> 00:04:15,340 In the next video we are going to read data from this table.
