Node.js - RESTful API

If you aren't using Web services in your development work, it's time to start consuming Web services whenever and wherever possible. Web services provide the modularization and scalability that other technologies have promised but have failed to deliver because of various reasons, including system compatibility and connectivity.

Thanks to the Internet, new ways to accomplish complex tasks and new standards have come about that allow systems to overcome those obstacles. SOAP is one of the standard protocols for communicating with Web services. Inside the WSDL, there is important information that explains how to make the call and details about the interface.

This WSDL is automatically generated from a. NET Web service. The tag wsdl:operation defines a Web method the service exports: AddTwoIntegers. And the parameters it receives are defined by the s:element tag whose name attribute, consequently, is AddTwoIntegers.

These parameters are easily identified as IntegerOne, of type integer, and IntegerTwo, of type integer. Once you identify your parameters, you can start to conceptualize your solution. Microsoft and Netscape, or Mozilla, both provide a method for creating the illusion of a connected application across HTTP through the use of a proxy component.

This component is provided as a standard component with newer versions of Internet Explorer and is marked safe for scripting. Using either of these components, you can make the call to the Web service and parse the result within your JavaScript code. This is done by opening the connection to the server, passing the appropriate headers and sending the appropriate request XML.

This method takes two parameters: the name of the header and the value. Listing B shows you how simple it is to make the call to the Web service. This code assumes that the call to the Web service will succeed. Also, you can check the status property of the proxy component. This property contains the HTTP response status returned from the server. For instance, an error on the server returns a status. As you can see, creating a client solution using JavaScript is pretty simple.

If you would like to fully understand the concept of the SOAP envelope and usage of complex data types to communicate with the server, you can find more details about SOAP on the W3C site.

How To Use an API with JavaScript (The Complete Beginner’s Guide)

First up, we'll start by looking at APIs from a high level — what are they, how do they work, how to use them in your code, and how are they structured? We'll also take a look at what the different main classes of APIs are, and what kind of uses they have. Application Programming Interfaces APIs are constructs made available in programming languages to allow developers to create complex functionality more easily. They abstract more complex code away from you, providing some easier syntax to use in its place.

Creating a Secure REST API in Node.js

The high-level programming language JavaScript also known as JS is mostly used to develop and control website content. It is described as a non-developer-friendly scripting language that is lightweight, weakly typed, and object-based. JavaScript Software Development is used to develop interactive websites with simple or complicated functionalities and designs, with the goal of providing a user-friendly experience. JS is used by the great majority of websites. This language is used to create interactive web pages and is an important component of online applications; practically every major web browser includes dedicated JS engines. These two are frequently mixed up and misunderstood! Java is an entirely distinct from JavaScript programming language that is written and executed in a completely different way. JavaScript is a weakly-typed language, whereas Java is a strongly-typed language. Instead of permitting everything, strongly-typed languages force you to declare code variables with data type limitations. JavaScript is strongly tied to the latest trends in Web Applications, but Java has a stronger footing in Enterprise Applications.

SAP Web Service Call via javascript

The proxy files function as a description of the web service methods, exposing the available service methods as well as their parameters. The client side application will either load the JSWS upon need, or it may be embedded into the page. An example of one of these files can be seen below. A side effect of this file instructing the browser in how the requests must be formatted is that it can also aid an attacker in enumerating web service methods and potential injection points.

The functions in the Places Library, Maps JavaScript API enable your application to search for places defined in this API as establishments, geographic locations, or prominent points of interest contained within a defined area, such as the bounds of a map, or around a fixed point. The Places API offers an autocomplete feature which you can use to give your applications the type-ahead-search behavior of the Google Maps search field. When a user starts typing an address, autocomplete will fill in the rest. For more information, see the autocomplete documentation. To use the functionality contained within this library, you must first load it using the libraries parameter in the Maps API bootstrap URL:. See the Libraries Overview for more information.

Service workers offer incredible utility, but can be tricky to work with at first. Workbox makes service workers easier to use. However, because service workers solve hard problems, any abstraction of that technology will also be tricky without understanding it. Thus, these first few bits of documentation will cover that underlying technology before getting into Workbox specifics. Service workers are specialized JavaScript assets that act as proxies between web browsers and web servers. They aim to improve reliability by providing offline access, as well as boost page performance.

How to call a REST web service API from JavaScript?

Reader Tip - Cick the Hide Sidebars link at the top right toolbar on this page to give you some more room to read this post on the screen, because it is code heavy. In this post I will show you how to enhance the built in functionality to also allow you to directly call the Kentico WebService from a JavaScript method. This is useful if you want to have some rich interaction on the client side of your pages such as creating a dynamic menu on the fly, or creating a rotating image banner. To start out, notice that there is an empty WebService sitting around in your project already. It is located at:. Now if you aren't familiar with an ASP. NET WebService notice that this looks like an empty page.
