ColdExt, the ExtJS Gateway Drug
coldfusion , extjs , JavaScript , Framework , AJAX , cftags Add commentsQuick post tonight, as I'm between tasks. I've been wanting for a long time to get more familiar with ExtJS, a most excellent JavaScript application framework (can I call it that?). It's the good stuff that's built into ColdFusion 8, but that was version 1.1. Since then they've gone all the way to 3.0, and the platform is getting better and even more expansive.
What I wanted to do was get into it, but I kept getting sidetracked. It can be a bit to digest in one sitting - or even 10. Eventually, I heard of ColdExt, which is a ColdFusion, er, helper application... well, it's like training wheels. I hope that doesn't offend anyone - particular the ColdExt gang. It's really amazing what they've done. Using their imported tags you can get off the ground really fast using the familiar tag-ness that is ColdFusion but when it's processed and sent to the browser it's all proper ExtJS JavaScript.
Now, I LOVE this. What it's doing is providing me, the developer, those all-important positive and productive feedbacks we call "success". In no time I had an AJAX-powered grid with a CRUD form hooked up to the rows. Even better is that some of the things I wasn't completely familiar with in the ExtJS syntax was getting written for me. A quick view-source and I was staring at a guide for how the under-hood-goods were written. This has helped me gain mountains of comfortability with this JavaScript framework!
So, even if you don't want to use ExtJS through a layer of ColdFusion tags in the end, I highly recommend you ease into the deep and incredibly powerful world of ExtJS via ColdExt. It put the "RAD" back into my AJAX/Rich Client applications. That's just awesome.
Aug 17, 2009 at 9:13 AM Nice write-up Adam, I'm glad you're finding ColdExt useful. You're right in that it's kind of like training wheels for getting started with ExtJS, and the nice part is that the tag names *are* the ExtJS object names and the attribute names *are* the ExtJS property names, so it makes it really easy to go without the training wheels if/when you need to. Having said that though, sometimes the training wheels will get you from A to B just as quick if not quicker :)
Aug 17, 2009 at 9:53 AM Yea, I started playing with ColdExt last week and it's awesome! Even got it working with Ext 3.0 with minimal effort. The stuff intellisense stuff for Eclipse makes using it a pure joy.
Aug 25, 2009 at 4:42 PM Justin, it's really painin' me right now that there's no tag-descriptions for Eclipse. And the documentation such as it is is very sketchy. Much, much more of a learning curve than I thought I'd have ... not even a clean "ajaxproxy" discussion that I have found yet. If there's anything out there, please point to it from your site!

<p>Once again, it's a pretty slow day for Met news. The most interesting story out there is Murray Chass's post on Omar's inability to multi-task this offseason. While I really despise anonymous sources, this does sound so stupid that it's probably true.</p>
