ECMAScript 6 (ES6, specification at http://www.ecma-international.org/ecma-262/6.0/) has many nice features, but presently not all browsers support ES6. However you can still develop your applications in ES6 and make it run in all browsers. For this you need what is called as transpiler – which converts ES6 code to ES5, which all browsers understand currently.
One of the popular transpiler is Babel . In this post we will see how to use Node.js (https://nodejs.org/), Gulp.js (https://gulpjs.com/), Browserify (http://browserify.org/) to compile ES6 code to ES5.
Gulp is a build tool for Node.js applications. Browserify resovles ‘require’ modules of Node.js and bundles all modules in one file. We will first use browserify to combine all our JS code in one file and then feed the output to babelify to translate the code to ES5. Structure of this sample project is as follows –
Not all the files are folders are shown above, for example package.json and node_modules folder are not shown.

Packt Publishing is having Thanksgiving sale from the 26th to the 30th of November, where their entire catalogue of e-books and videos are being offered for 50% off.
As part of this sale you can now get 50% off on my book – Java EE Development with Eclipse – Second Edition.
My second book “Java EE Development with Eclipse – Second Edition” has been published. One of the reasons I did not post much on the blog was this book. I had been working on the book for the past few months and I am very glad that it has been published now.
One of the challenges writing this book was the diverse topics that it covered – Servlets, JSP, JSF, JDO, EJB, JSM, SOAP, REST, Spring, Unit Testing, Debugging and trouble shooting performance and memory issues in Java applications. Separate books could be written, and books have been written, on some of these topics.
This book explains how to develop applications using these technology in Eclipse IDE. The focus is not just on how to use different technologies in JEE, but also on setting up development environment, testing, debugging and deploying applications developed using these technologies.
The book is available on the publisher’s site at bit.ly/1GryrTd.
As at the end of past couple of years, WrodPress has created annual report of my blog activities. The report is available at http://jetpack.me/annual-report/33403624/2014/.
Some of the highlights are –
Unfortunately I did not get much time to blog in the last three months. I had many topics on which I wanted to write on, but the work schedule was quite hectic. I hope to write on those topics in the coming months.
I spent a couple of hours today trying to figure out how to configure Apache Web Server on Mac OS X to execute Python scripts, so I thought I would document the process for my own reference.
OS X is preinstalled with Apache and Python. Apache executable (apachectl) is at /usr/sbin/apachectl and Python is at /usr/bin/python. But the configurations for Apache are at /etc/apache2, specifically in the file httpd.conf. If you open the file and look for DocumentRoot, you will find that default document root is set to /Library/WebServer/Documents.
I did not want to change the default doc root but at the same time did not want to store my scripts in the default folder. I could have created a virtual host or an alias. I decided to do the later because it is simpler than creating virtual host; and I was configuring Python for development only. So just below the document root setting I added the alias – Continue reading “Configuring Apache on Mac OS X (Mavericks) for Python scripting”
Before I proceed further, I must confess that my knowledge of encryption and digital security in general is very basic. So the solutions discussed in this post may not be the best in terms of protecting the data.
As I said, Crypto-JS is very simple to use. You can use different cipher algorithms like AES. DES etc. and APIs are simple. e.g. to encrypt using AES , you would call –
encryptedData = CryptoJS.AES.encrypt(textToEncrypt, secretPhrase); //include aes.js script
After working in Macromedia/Adobe for ten years I decided to quit Adobe. Today was my last day at Adobe.
The last ten years at Adobe have been professionally and personally very satisfying for me. I have worked on some of the most technically challenging assignments in my career so far. Learnt a lot and put my learnings back into the products I worked on.
On the last day when I was reflecting on my journey in Adobe, I recall my interview as a candidate. Macromedia did not have an office at that time in Bangalore and I was interviewed in Windsor Manor hotel. I was the first engineer recruited for ColdFusion in Bangalore. When I joined the ColdFusion team, ColdFusion 7 release was in the final stages. I started with fixing a few bugs towards the end of the release. After that I worked on many features of ColdFusion and ColdFusion Builder in the subsequent releases.
Till a couple of months back I was not thinking about quitting Adobe. But then an opportunity came along that was so different from the way I was working in Adobe that I decided to take it up. I might write more about it later.
My best wishes to the ColdFusion team and the ColdFusion community.
P.S. I joined back Adobe in June 2015.
I was experimenting with using AngularJS and JQueryMobile together and loading pages dynamically. The page loading and routing can either be handled by JQueryMobile ($.mobile.pageContainer.pagecontainer(“change”,“page_name”)) or AngularJS. With AngularJS you can use $route service along with ngView and/or use ngInclude .
ngInclude looked easy enough to start with, but did not turn out to be that easy. I will take as simple example of a login application. If user is not logged-in, the app will display the login page and after successfully logging in, the application will display the main page, with the option to logout.
