Microsoft today released Node.js tool 1.2 for visual studio 2015. The new tool supports all editions of visual studio including community edition also. The new version packs with many new fixes and developments for intellisense, debugging process and for testing experiences. Check out full change log below.

What’s new in latest version?
Faster, better ES6 IntelliSense:
Whether you were running into performance issues or craving the latest and greatest JavaScript goodness, the new ES6 IntelliSense experience is now on by default, and better than ever! The new ES6 IntelliSense engine takes advantage of type definition files to provide better and more performant IntelliSense. This is applicable for the most popular Node.js frameworks, such as Commander, Express, jQuery and Knockout.
More reliable debugging:
Advanced debugging is the cornerstone of NTVS, we’ve made it even better by addressing several user-reported issues. So if breakpoints weren’t working properly sometimes, or things were generally inconsistent, be sure to download this release to get the latest fixes!
Improved Performance:
Hangs and crashes are a drag, but not anymore! This release provides significantly improved stability and performance, including reducing out-of-memory crashes seen in prior versions. We’ve also made several improvements to our project system, so you can expect improved project load times (especially during “Add from Existing Code”).
Improved Unit Testing Experiences:
While it’s generally best practice to avoid writing bugs altogether, some of us are not omniscient, and find unit tests to be pretty helpful. So we’ve made some improvements to the unit testing experience, including adding tape support.
