Most of my javascript work is done with Firebug and I feel annoying most of the times having to switch between the HTML mode and console mode (which again I split into output mode and input mode). When I switch to a different page to see the HTML and come back, I lose the code that I write. What is the best way to go about developing javascript applications using firebug?
Something like a mini IDE would be awesome: It just has to let me insert some code, examine the current page and then let me execute it. Any suggestions?
I use a simple text editor (vim) to write Javascript and HTML, and I check the result every now and then in Firefox. I have always two windows open: one for my text editor, and one with the current page open in Firefox. After saving a change in the Javascript, I switch to the browser and refresh the page to observe results. That was my workflow until recently.
A couple of weeks ago, I discovered the Combiner tool by Nicholas C. Zakas. To release my Javascript code, I am now using a complete build process based on Apache Ant, similar to what I was using while doing Java development previously.
The first step is to check the Javascript code with the JSLint tool by Douglas Crockford. I used to painfully copy and paste my Javascript code in the online version of the tool, once in a while; being able to run it on all my Javascript files at once with this Ant script is a huge convenience.
The second step is to combine all my Javascript files into a single file using the Combiner tool. The third step is to minify the Javascript code using YUI Compressor by Yahoo!. These last two steps allow to optimize the delivery of Javascript code to reduce page loading.
You can find an example Ant build file that you may adapt to your own needs. I am currently using this file to build my own Javascript library, bezen.org.
