If someone were to take this and expand it, then yes, I suppose it could become possible to run a Flex 4 app in JS with very few changes.
What are these two doing? Well... OpenFL is a reimplementation of the Flash API written in the Haxe programming language. Haxe can be compiled to JS. There's a version of OpenFL available that is pre-compiled to JS, so that JavaScript developers can use it. See here on NPM: https://www.npmjs.com/package/openfl The Royale compiler is converting the AS3 source code of the Flex framework to JS. I used Flash's playerglobal.swc file with the external-library-path compiler option to trick the compiler into thinking that the Flash API was available in JS. It could also be done with OpenFL externs/typedefs written in AS3, but this was the fastest way for me to do it. In my HTML file, I added the OpenFL JS library: <script src="https://unpkg.com/[email protected]/dist/openfl.min.js";></script> Then, I included this line of JS to make OpenFL look like Flash: var flash = openfl; There's a bit more involved in getting everything bootstrapped, and some random Flash APIs are missing from OpenFL, but that's the basic idea. -- Josh Tynjala Bowler Hat LLC <https://bowlerhat.dev> On 2021/09/10 09:50:35, yushiro maeda <[email protected]> wrote: > Hello, > > Thank you always, it's very interesting!! > > > If what's happening here evolves after this, for example, can I automatically > convert code written in Flex4 directly to javascript without having to > rewrite it for Royale? > > So is migration (Flex 4 to Royale) unnecessary? > > I'd like you to tell me a little, > It seems that both Royale and OpenFL convert from AS3 to Javascript in the > same way. > > What are these two doing? > > I would appreciate it if you could tell me. > > thank you. > > On 2021/09/09 20:19:57, Josh Tynjala <[email protected]> wrote: > > Hey community, > > > > I just wanted to share a little demo I put together as a way of pushing the > > capabilities of the Apache Royale compiler.
