The JavaScript Flash API or JSFL lets you write scripts to perform several actions within the Flash environment. The possibilities of using JSFL are endless allowing you to create custom commands, tools, timeline effects, behaviors, etc.

Over the years, many JSFL extensions have surfaced within the Flash community. Below are a collection of 20+ JSFL extensions ranging from audio/lip syncing to tween management to Git/Svn version control. Enjoy!

If you have either developed or know of an awesome JSFL extension that I missed from this list, feel leaving a comment below. Thanks and enjoy!

Anytime you can extend your tool sets to fit a much more simplified work flow, the better control you have over the tool versus the tool over you.  Being able to store code snippets within Flash has been a feature that I am sure a lot of Flash users would love to have available.  You’d think a functionality like so would already to integrated within Flash, however until then you can focus your attention to ASExpander.

What is ASExpander?

ASExpander is a JSFL extension created by Keith Peters for Flash CS3/4 that allows you to integrate a ActionScript snippet functionality into your existing Flash workflow.  ASExpander allows you to store your existing or new ActionScript code snippets into an external file and then map it to a command of your liking.  There are no limits to the amount or type of snippets stored.

While the ASExpander does have its flaws like no interface to interact with it, it is a very nice alternative to a previously created snippets panel created Lee Brimelow.
