Asynchronous Definition of Customer Object in Class: A global solution
When creating a simultaneous or distributed application, it is customary to connect to servers or other parameters in a scalable way. However, the creation of an asynchronous client object that can be used throughout the classroom is not easy.
JavaScript you have two main options for connectivity and asynchronous communication management: promises and async/wait for Apis (especially async functions). Unfortunately, none of these approaches provide a global solution to determine the asynchronous customer object for your class.
Therefore, we will study alternative solutions that can help achieve this goal.
Problem with promises
Promises are a fundamental concept of JavaScript that allows you to handle asynchronous surgery. However, they are not suitable for connections throughout the class because:
- Each case of a client’s object is an independent promise to make it difficult to share or manage.
- The API
API is intended to be submitted to requests on a single instance principle, which may lead to non -compliance with the data received.
Solution: Library -based approach
To overcome these restrictions, we will set up a library that provides a global solution for asynchronous client object. This approach is related to:
Class 1 Creating a logic of connection and management.
- Provision of compounds and asynchronous operations management methods.
Here is an example of implementation:
JavaScript
// Client.js
class asyncclient {
Constructor (URL, Options) {
This.url = URL;
This.options = Options || {};
}
async makerequest () {
CONST reaction = wait for this.url, this.options);
Return Response.jon ();
}
}
Export default asyncclient;
`
`JavaScript
// App.js
Import {asyncclient} from ‘./client’;
Const Client = New asyncclient (‘ {
Method: “Get”,
headers: {
“Content Type”: “Application/JSON”
}
});
client.makerequest (). Then (Data => {
Console.log (data); // Data from Answer
});
`
Customer class use
Now that we have a library -based approach, we can reuse the class “asyncclient” throughout our application:
`JavaScript
// ExperpleApp.js
Import asyncclient from ‘./client’;
Const Client = New asyncclient (‘
client.makerequest (). Then (Data => {
Console.log (data); // Data from Answer
});
CONST CITURCLENT = New asyncclient (‘Other Connection’);
Citaclient.makerequest (). Then (elsewhere => {
Console.log (elsewhere); // Data from another request
});
`
Benefits and Cases of Use
This library -based approach offers several benefits:
* Global Consistency : Each case of AsynCClient has the same logic of connection and management, ensuring consistent behavior throughout your application.
* Code Re -use : In the class “AsynCClient” can be used in several parts of the code base, reducing duplication and improving maintenance.
In cases of use, this library is particularly appropriate:
* Web applications
: For connections with external services or the API web app requires an asynchronous client object that can be used in all cases.
* NODE.JS Application : When designing without server or scalable Node.The application using asynchronous client object can simplify the development process and improve performance.
With this library -based approach, you can create a more stable and maintained asynchronous customer object for your entire class, providing consistency and code reuse throughout your application.
