Implementing SVG in JavaScript

SVG or Scalable Vector Graphics is simple image format that can be easily implemented in various programming languages including JavaScript and Ajax. It's commonly used in websites because of its ease of implementation and, as the name suggests, can easily be customized depending on the need of developers.

SVG will also work in JavaScript and Ajax simply because the image format is based on XML. Streaming image from the server or from a 3rd party source in JavaScript is very easy. It's basically data but instead of raw information, it's an image streamed in the application.

Working with API

Even though SVG is based in XML, there is no default support coming from JavaScript in order to fully implement this type of image format. Developers have to find ways in order to easily implement SVG.

A common solution developers can consider in order to easily implement SVG in their Ajax or JavaScript based application is to use an API. There are various APIs dedicated to SVG loading in JavaScript but a notable API developed by Oracle is increasingly popular. When using an API, developers will be able to gain access of various commands so that the SVG file can be easily implemented and manipulated in the client side.

The only disadvantage of API is that it can be too heavy for developers who simply wanted to create small JavaScript and Ajax applications. But full online application should have no problem using an API.

Working with a Library

Another option developers can consider for properly implementing SVG in an online application is to use a library. jQuery, MooTools and Prototype have specific libraries improved by other developers so that JavaScript can implement SVG.

A popular library based on another library is Raphael JS. This tool was developed based on jQuery and can help developers implement SVG without additional coding. The most impressive feature about the library is that the library will even help developers build charts from the scratch. It's also very easy to understand since the function is based on jQuery.

Tips for a Lightweight SVG

When implementing SVG in an Ajax or JavaScript based application, it's important to remember the main reason why SVG is used. Developers can use JPG and other image formats in Ajax or JavaScript based applications but it can be too heavy for users. SVG can provide the same experience without being heavy on users and in the application.

To implement lightweight integration of SVG in the online application, developers have to concentrate on the basics before using the full version of the API or library.

When using a library, it's a good idea to implement SVG before any manipulation. Developers can simply manipulate or make some changes on the image after they are part of the online application.

This will improve compatibility in the application. This technique should also be observed when using an API. Most, if not all, APIs come with full customization tools so a raw SVG file will work well in an Ajax or JavaScript based application because of additional customization.
