1 00:00:00,420 --> 00:00:08,160 In this video we are going to learn Ada Lovelace SDK for JavaScript Version three and using SDK with 2 00:00:08,160 --> 00:00:15,990 Node.js, the ADA SDK for JavaScript version three API reference quite provides a JavaScript API for 3 00:00:15,990 --> 00:00:17,490 Ada Lovelace services. 4 00:00:17,490 --> 00:00:22,770 We can use the JavaScript API to build libraries or applications with Node.js. 5 00:00:23,310 --> 00:00:30,210 The ADA Lovelace SDK for JavaScript version three is a rewrite of version two with some great new features. 6 00:00:30,360 --> 00:00:36,120 As with the version two, it enables you to easily work with the ADA Lovelace resources, but has a 7 00:00:36,120 --> 00:00:40,020 modular architecture with a separate package for each services. 8 00:00:40,470 --> 00:00:46,980 It also includes many frequently requested features, such as a first class TypeScript support and a 9 00:00:46,980 --> 00:00:48,480 new middleware stake. 10 00:00:48,870 --> 00:00:51,630 We can use SDK with Node.js. 11 00:00:51,660 --> 00:00:56,610 Node.js is a cross-platform runtime for running server side JavaScript applications. 12 00:00:56,610 --> 00:01:01,470 During the course, we will use Node.js to write On-Demand ADA Lambda functions. 13 00:01:02,220 --> 00:01:06,840 So we will have two main resources one, developing our interactions. 14 00:01:06,870 --> 00:01:13,620 The first one is a SDK for JavaScript developer wide four SDK version three documentation, and second 15 00:01:13,620 --> 00:01:18,120 one is the SDK for JavaScript version three API reference. 16 00:01:18,120 --> 00:01:23,580 Quite so you can find the example quotes about the dynamic DB interaction with the SDK. 17 00:01:23,610 --> 00:01:25,710 Let me open one more one by one. 18 00:01:25,740 --> 00:01:29,310 This is the developer guide and here is the API reference. 19 00:01:29,310 --> 00:01:29,910 Quite. 20 00:01:30,980 --> 00:01:36,680 So, for example, if you will, if you would like to learn about dynamic web interactions, you can 21 00:01:36,680 --> 00:01:43,430 come here and if you scroll down and getting started, part of this API reference documentation, it 22 00:01:43,430 --> 00:01:45,320 is giving you an example of the Dynamo. 23 00:01:45,320 --> 00:01:45,890 DB. 24 00:01:46,070 --> 00:01:52,640 Basically, we will use Dynamo DB package for Dynamo DB client object and use the some of the commands 25 00:01:52,640 --> 00:01:55,350 that represents to Dynamo DB APIs. 26 00:01:55,370 --> 00:02:01,850 So this is the module architecture with the JavaScript version three, and we can use every resource 27 00:02:01,850 --> 00:02:03,120 with different libraries. 28 00:02:03,140 --> 00:02:10,280 It can reduce dramatically the package size and increase the code start issues and solve these issues. 29 00:02:10,310 --> 00:02:12,590 You can see the examples in here. 30 00:02:12,590 --> 00:02:19,250 So basically here in the right hand side, you can see that every package is including in here. 31 00:02:19,250 --> 00:02:25,820 For example, if you search for the case, you can see the ASCs package client is grace. 32 00:02:25,820 --> 00:02:31,940 If you click the SE case, you can see how we can use these tools in order to interact these almost 33 00:02:31,940 --> 00:02:38,210 on a case to put input event and consume event from the space. 34 00:02:38,210 --> 00:02:43,880 So as you said that the idea is that we are installing only required package. 35 00:02:43,880 --> 00:02:49,490 So by this way it can reduce the function library package size with only installing required package. 36 00:02:49,640 --> 00:02:51,590 Also you can search the example. 37 00:02:51,590 --> 00:02:56,930 For example, we will interact with the OR event each object. 38 00:02:56,930 --> 00:03:03,320 You can search for the event page and go to event page library and if you scroll down you can see how 39 00:03:03,320 --> 00:03:11,810 we can import and how we can use event page to perform operations with Event Bridge, how we can put 40 00:03:11,810 --> 00:03:15,020 the events and consume the events from the which. 41 00:03:15,020 --> 00:03:22,370 So at the same way you can follow the case, Psns and other Ada Willis resources that we can interact 42 00:03:22,370 --> 00:03:25,760 with using the SDK for JavaScript Version three. 43 00:03:25,940 --> 00:03:31,850 If you come back to our developer guide for SDK here, you can see the developer guide that we can also 44 00:03:31,850 --> 00:03:33,620 use this developer guide. 45 00:03:33,650 --> 00:03:37,070 Here you can see the very good examples code examples section. 46 00:03:37,070 --> 00:03:40,580 If you scroll down, you can see the code examples in here. 47 00:03:40,610 --> 00:03:47,750 For example, if you scroll down, you can see the Amazon Dynamo DB in here we can perform the Amazon 48 00:03:47,750 --> 00:03:49,100 Dynamo DB operations here. 49 00:03:49,100 --> 00:03:55,130 Different actions create the table, delete table, list, table, query, table, and so on. 50 00:03:55,130 --> 00:04:01,640 We already perform these actions with using the console, a replacement console and also select commands. 51 00:04:01,640 --> 00:04:05,990 And this time we will perform these operations using the Ac-dc package. 52 00:04:05,990 --> 00:04:13,790 And specifically we will use a script six name version of the SDK JavaScript version three libraries. 53 00:04:14,180 --> 00:04:24,320 So you can see the our resources that we will perform interactions with the resources using the SDK. 54 00:04:24,350 --> 00:04:32,000 As you can see that we have seen a SDK for JavaScript version today, both developer guide and also 55 00:04:32,000 --> 00:04:32,780 API reference. 56 00:04:32,780 --> 00:04:33,830 Quite so. 57 00:04:33,830 --> 00:04:41,060 Now we are ready to implement CRUD operations into our product microservices bit using a SDK for JavaScript 58 00:04:41,060 --> 00:04:41,870 version three.
