Best Realtime Java Web Application Frameworks
Nowadays, it's a common requirement to show realtime data in the web applications. In Java, there are lot of frameworks available to build web applications. Some frameworks provide inbuilt support for realtime updates in the web application. In most of the mvc frameworks we have to manually handle code to show realtime updates in the UI. This might possibly lead to bug in the future modification otherwise we have to test all features thoroughly when an enhancement is made.
This blog is to introduce about an excellent java framework which internally handles all of the realtime changes to synch with the UI. It's webfirmframework which is an open source Java framework came in 2014-2015. Unlike other frameworks, it uses a different design pattern called MLTP. It's an HTML5 supported framework. When we are developing applications with this framework, we don't keep any html files. We write java codes which can produce HTML content so there is no html files and only Java classes. There are lot of advantages with framework, some of them are performance, security and freedom to generate any structure of html in the ui in realtime. As it uses the core websocket communication internally, we can find a sparking performance while the ui is updated. It's a kind of server side framework, all of the ui logic is kept and processed in the server side and syncs only the ui changes to the browser so it's perfect where ui security is a big concern. And if there is any change the server side even without a trigger from the client the change will be synced to the browser ui. That's why it's considered as a realtime application development framework.
Another big advantage is the readability of code written in the application when using this framework. It uses the coding style which is similar to a markup language structure. All tag classes contain tag manipulation methods like appendChildren, removeChildren etc...See this sample code taken from its website.
Html html = new Html(null) {{
new Head(this);
new Body(this) {{
new NoTag(this, "Hello World");
}};
}};
// prepends the doc type <!DOCTYPE html>
html.setPrependDocType(true);
System.out.println(html.toHtmlString());
this java code produces the below html output
<html> <head></head> <body> Hello World </body> </html>
There are few sample projects available in this website and they are enough to get started.
You can simply convert HTML5 to Java code using the tool provided in its main website. Simply paste the HTML5 content in the left box and click the convert button then we get the corresponding java code the right box. It simplifies the develop effort. We can also use this tool to find the corresponding class of a particular html tag or attribute so it avoids a lot of HOW TO forum posts.
If you in depth knowledge in Java and basic understanding of html5 then you are good to go. It's a kind of framework which gives an approach like "START CODING WITHOUT LEARNING".
Another advantage is when we are writing ui codes in java, we will have a tendency to use minimal number of tags. That is a great optimization for UI performance.
IntelliJ is the best IDE for developing wffweb apps because it formats code perfectly for wffweb. Other IDEs like eclipse is also good. All java build or deployment tools like maven, gradle, ivy etc.. provide support for wffweb.
When we have a requirement of developing realtime app, single page app, business app or any other complex ui development apps then this framework perfectly fits in the context.
Thank you for sharing this wonderful blog. It will help to improve my knowledge about JAVA frameworks. This blog will know more about JAVA concepts. Also, it will improve my programming skill.
