Hi Josh,

compliments to what you've already achieved. Looks promising and I'm considering giving it a try, when I'll start porting an AS3 project to Javascript.

The first project will be pure AS3, but I have another project in mind that makes heavy use of Flex and would be a nice candidate to test FlexJS.

So far I considered Typescript and most probably React as framework for the first project; perhaps together with Pixi (if I do not continue using a JS library that actually does most of the display list related things).

But something like continuing developing in AS3 and then "simply" convert it to JS sounds too nice to be true.

But if I understood things about NextGenAS correctly, that could be possible. No sure how to handle dozens of classes, but I'll find out.

Before I dive into all that, I have a short question you hopefully can answer:

You focus on VS Code as IDE. I'm used to IntelliJ IDEA, and prefer using that.

I know you're an IntelliJ user also and iIrc you even plan a video about that topic.

So what is your recommended approach for me?

Thanks and regards

VSCode doesn't really have its own concept of project templates. I think
Microsoft recommends using something like Yeoman. http://yeoman.io/

That said, VSCode extensions can add commands to the Ctrl+Shift+P command
palette. For instance, the NextGenAS extension has a custom command to
generate a tasks.json file that runs asconfigc. I think it would be
possible for an extension to add a command that creates and populates a set
of files as a way to generate a new project. There are a few options for
displaying simple UI (pick from a list of options, choose a file, show an
alert bar with a few buttons), so the wizard could ask a few questions in
the process.

That would be perfect. Automatically adding imports is something I’m
really missing in VS Code.

“Organize imports” is another item that would be really nice to have.

“Command 1”  is something else I use in Flash Builder regularly.
Generating getters and setters from variables is a great time saver. (Other
quick fixes too)

I’m really pumped up about your extension. Good tooling for FlexJS is
really important IMO, and tooling built around a modern editor with
features like multi-selection, etc. is great.

What would be involved in having templates for different project types? Is
that something that’s do-able in VS Code?

Yeah, the "code actions" are pretty cool as a way to provide automated
fixes for errors and warnings. I hope to find more places to add those.
for imports, the newest language server protocol will finally allow me to
add imports automatically when IntelliSense completes a type name, so I'm
looking forward to upgrading the library and implementing that feature.

I tried to comment on your Patreon post, but Patreon is not letting me

It looks really good! Big improvement!

The help tip to add imports is really helpful as well!

Thanks for your great work!

Hello, Flex community!

A couple of months ago, I introduced a new extension for the Visual
Code text editor that adds language support for ActionScript. The
includes tons of code intelligence features for ActionScript, like
IntelliSense, find all references, goto definition, variable renaming,

I didn't officially announce the project to the Apache Flex community
away because, at the time, the extension only supported ActionScript,
and I
hadn't started yet on MXML features. As we all know, MXML is pretty
for Flex applications!

Today, I'm happy to announce that the newest version of the NextGen
ActionScript extension for Visual Studio Code includes all the same
features for MXML. You can install the extension right inside Visual
Code. Simply search for "NextGen ActionScript" in the Extensions view.

For more information about the NextGenAS extension, visit the website:


For instructions about how to create a new project, set up the
and even debug Apache FlexJS apps in a web browser, visit the Github

With the community's help, I can continue working on useful developer
for ActionScript and MXML. Please join my Patreon campaign to lend a

Thank you, and happy coding!

Note: I am an Apache Flex committer and PMC member, but this VSCode
extension is not an Apache project. Today, I am simply posting as a
of the community who wants to share a cool, independent project that
might enjoy.
