HTML5 Development

HTML5 Development in Java EE and PHP Applications

You can now use all the HTML5 development features (collectively known as Project Easel) in Java Web applications (Ant or Maven based) and in PHP applications. For a more detailed description, see the Java EE and PHP sections of this document.


Create a new PhoneGap application from template. A PhoneGap application is just a flavor of a HTML5 application, so you can turn any HTML5 application into a PhoneGap application very easily.

Build, Deploy and Run Mobile Applications developed using standardised web APIs on Android/iOS Simulator or Device.

PhoneGap Sample Application

PhoneGap Sample application shows how to write rich mobile applications in HTML5 and Javascript using JQuery, PhoneGap (Geolocation API and Contacts API) and Google Maps API. The very same code can be tested on both iOS and Android devices.


Support for Android and iOS Browsers


CSS Preprocessors


Basic editing support for Sassy CSS and LESS CSS preprocessor files has been added to Netbeans dev build. The work is still in progress, but the main part is ready to use:

  • syntactic and semantic (parser based) coloring for the language constructs,
  • indentation, simple reformat of code,
  • code folds,
  • file templates

For variables and mixins we provide:

  • go to declaration,
  • mark occurrences,
  • instant rename,
  • code completion (also shows items from imported files),
  • vars, mixins and imported files shown in the navigator,
  • find usages and refactor rename among files.

Compilation on Save

When you edit Sass and LESS files, the IDE will automatically compile these into CSS when you save the file. You only need to set the output path (or more precisely, mapping from input to output files) in your project's properties.


Then you only need to tell the IDE where to look for the Sass and/or LESS compiler, via the IDE Options.


Network Monitor

Network monitor helps to analyze REST related communication, WebSocket communication and any network requests which failed. It is available for Chrome with NetBeans Integration and Embedded WebKit Browser.

For each request it displays request and response headers:


and response received from the server:


and call stack which triggered this network request:


For WebSocket communication all text frames are displayed:


The network monitor tries to provide help in certain common situations:


JavaScript Libraries

  • ability to refresh available libraries

HTML5 Development in Java EE applications

The following HTML5 development features are now available in Java EE applications (both Ant and Maven based):

  • Browser selection for testing with various browsers
  • Running on mobile browsers on Android and iOS devices and emulators

Frameworks & Tools


  • Static code analysis - support for code inspection (code sniffer, mess detector).



Initial support for Knockout framework providing code completion in JavaScript files.


Ext Js

Simple support for Ext Js framework providing code completion in JavaScript and HTML files. There are three contexts, where code completion items are offered through the Ext Js framework support:

  • Code completion for Ext object:


  • NetBeans understand to defining objects through Ext.define or Ext.apply methods. On the picture you can see navigator, that displays object defined through the Ext.define method and code completions suggester for such object:


  • NetBeans offers code completion for property names in objects that are parameters for methods like Ext.application, Ext.define etc.:



License Header template selection in project UI, template itself can be placed in project space locations. File:License_headers.png
