In this video we are going to learn Ada Lovelace SDK for JavaScript Version three and using SDK with
Node.js, the ADA SDK for JavaScript version three API reference quite provides a JavaScript API for
Ada Lovelace services.
We can use the JavaScript API to build libraries or applications with Node.js.
The ADA Lovelace SDK for JavaScript version three is a rewrite of version two with some great new features.
As with the version two, it enables you to easily work with the ADA Lovelace resources, but has a
modular architecture with a separate package for each services.
It also includes many frequently requested features, such as a first class TypeScript support and a
new middleware stake.
We can use SDK with Node.js.
Node.js is a cross-platform runtime for running server side JavaScript applications.
During the course, we will use Node.js to write On-Demand ADA Lambda functions.
So we will have two main resources one, developing our interactions.
The first one is a SDK for JavaScript developer wide four SDK version three documentation, and second
one is the SDK for JavaScript version three API reference.
Quite so you can find the example quotes about the dynamic DB interaction with the SDK.
Let me open one more one by one.
This is the developer guide and here is the API reference.
Quite.
So, for example, if you will, if you would like to learn about dynamic web interactions, you can
come here and if you scroll down and getting started, part of this API reference documentation, it
is giving you an example of the Dynamo.
DB.
Basically, we will use Dynamo DB package for Dynamo DB client object and use the some of the commands
that represents to Dynamo DB APIs.
So this is the module architecture with the JavaScript version three, and we can use every resource
with different libraries.
It can reduce dramatically the package size and increase the code start issues and solve these issues.
You can see the examples in here.
So basically here in the right hand side, you can see that every package is including in here.
For example, if you search for the case, you can see the ASCs package client is grace.
If you click the SE case, you can see how we can use these tools in order to interact these almost
on a case to put input event and consume event from the space.
So as you said that the idea is that we are installing only required package.
So by this way it can reduce the function library package size with only installing required package.
Also you can search the example.
For example, we will interact with the OR event each object.
You can search for the event page and go to event page library and if you scroll down you can see how
we can import and how we can use event page to perform operations with Event Bridge, how we can put
the events and consume the events from the which.
So at the same way you can follow the case, Psns and other Ada Willis resources that we can interact
with using the SDK for JavaScript Version three.
If you come back to our developer guide for SDK here, you can see the developer guide that we can also
use this developer guide.
Here you can see the very good examples code examples section.
If you scroll down, you can see the code examples in here.
For example, if you scroll down, you can see the Amazon Dynamo DB in here we can perform the Amazon
Dynamo DB operations here.
Different actions create the table, delete table, list, table, query, table, and so on.
We already perform these actions with using the console, a replacement console and also select commands.
And this time we will perform these operations using the Ac-dc package.
And specifically we will use a script six name version of the SDK JavaScript version three libraries.
So you can see the our resources that we will perform interactions with the resources using the SDK.
As you can see that we have seen a SDK for JavaScript version today, both developer guide and also
API reference.
Quite so.
Now we are ready to implement CRUD operations into our product microservices bit using a SDK for JavaScript
version three.
