Fun with ExtJS
These two weeks, I had the chances to play with ExtJS. The widgets are just amazing! Although I have lots of frustation (and hair losses) due to API docs are not beginner friendly (strictly my opinion), lots of other resources available on the net to help me to get started. Official user documentation would be helpful if they provided one, though. Fortunately, using the widgets couldn’t have been easier and they provided examples with the download. So now, with ExtJS, I can build desktop-like GUI in a jiffy so I have more times developing the backend.
In terms of licensing, I’m pretty much unclear of what I can and can’t do if I opted using GPL. But If I’m not mistaken, when a library is GPLed, everything built on top of that library needs to be GPLed too (is that correct?). Certainly, commercial license is the way to go if I want to sell a product that make use of ExtJS extensively but USD289 (that’s about RM965.26) for a single developer license is not a cheap price to pay. Despite the price, ExtJS is a robust javascript framework and I’ll be glad to support them, if I had money.
