Object ServiceInstance is a first-class object in JavaScript that provides information and allows us to retrieve content from a server. Here, we will provide a step-by-step guide on how to call and retrieve content from a server using the ServiceInstance object.
Prerequisites
Before beginning this guide, make sure you have the following prerequisites and dependencies in place:
- Familiarity with the Vanilla JavaScript Syntax
- Access to a web browser
- An established connection to the server containing the desired content.
Step 1: Create an Instance of the ServiceInstance Object
In order to interact with and retrieve content from the server, you must first create an instance of the ServiceInstance object. This can be done by the following code:
//Create a new instance called myServiceInstance
let myServiceInstance = new ServiceInstance(options);
Where the options parameter is an optional argument that defines which properties of the object you want to instantiate.
Step 2: Access the Retrieve Method
Now that an instance of the ServiceInstance object is created, you can access the retrieve method of the object. The retrieve method will allow you to access the content stored on the server. To access the retrieve method, use the following code:
myServiceInstance.retrieve();
The retrieve method will return a Promise with the retrieved content from the server.
Step 3: Resolve the Promise
Once the Promise is returned from the retrieve method, you must resolve the Promise to access the content from the server. To do so, use the following code:
myServiceInstance.retrieve().then(function(result) {
// Process the retrieved content here
});
The result parameter above will contain the desired content from the server.
