JSDT uses a new parser with EcmaScript 2015 (ES6) support. This allows JSDT to recognize and support ES6 language constructs and provide better validation accuracy compared to earlier parser.

As this is the initial drop of ES6 support, not all JSDT features are connected with the new parser in this milestone.

JS Editor

JSDT is now supporting two package managers Bower and npm. There are wizards for creating bower.json / package.json and launch shortcuts for executing update and install commands.

NPM Wizard

Bower Launch

Bower Console

Both package managers fall back on native implementation, hence the following software must be pre-installed on the system:
  • Node.js
  • Bower
  • NPM
Grunt and gulp build systems are available in JSDT. All tasks are accessible from the project explorer view and can be executed via launch shortcuts.

Gulp Launch

Gulp Console

Node.js applications can be debugged via Chromium V8 debugger. For now debugging via virtual file system is only supported. This feature is available in the WTP Neon M6 repository, but not included by default, search for "JavaScript Development Tools Chromium/V8 Remote Debugger"

Chromium Debugger

JSDT now provides a Node.js runtime definition via Eclipse Preferences -> JavaScript -> Runtimes
Node.js Runtime
Also there is a new Node Launch configuration for running / debugging Node.js applications.

The process of debugging has been significantly improved. Now all debugging happens directly in the JSDT editor

While debugging, all JavaScript variables will be available in the *Variables* view

Hovering over variables in the editor is also supported:
