We are starting to develop a web application that will have complex functionality written on HTML5 canvas.
Please, could you recommend any good IDE (open or commercial) or a set of tools for developing / debugging such applications?
Thanks in advance.
I prefer Aptana Studio for developing web applications, as this provides very good support for javascript, HTML and even new libraries such as coffee script. The latest version of Aptana Studio in beta also supports HTML5.
It may not be exactly what you are looking for ... but you can take a look at jsFiddle - http://jsfiddle.net/
If you cannot use it for the main parts of your web application, you can at least use it as a debugging tool.
