Hi Piotr,
These are good questions. I think they are more suited for the dev mailing list because it involves discussion of the internals. If you want to learn more about the compiler this [1] could be a good start.

Hope someone can help me to understand: 1. How does the index.html relate to HelloWorld.js in the js-release folder? Is the stuff in js-release generated based on the js-debug? 2. Are all the 250 goog.goog.addDependency() lines really needed? 3. In the first line: goog.addDependency('../../../HelloWorld_mx_managers_SystemManager.js', ... I have removed many item(?) in the 'requires' argument, e.g. 'org.apache.royale.utils.Timer', and the webpage is not visibly affected. How/where is it decided what does into this argument? Any help will be appreciated, Piotr On Tue, Oct 20, 2020 at 2:42 PM Greg Dove <[email protected]<mailto:[email protected]>> wrote: Hi Piotr, Emulation will always have more weight because, in addition to a reasonably 'heavy' (but very capable) framework, in js there is also emulation of certain flash player features that were not part of the flex framework itself but are not present in the browser. (such as emulation of flash.utils.Timer, for example). There are undoubtedly improvements that we can make over time to reduce size. But emulation's main priority is to 'get things working' first, so I do expect that will come later. But also it is not simply correct to compare HelloWorld.swf with HelloWorld.js The HelloWorld.swf is internally compressed with lzma compression after it has been built. HelloWorld.js would typically be deployed on a server that uses gzip compression when sending content. The 'minified' js output is optimized for this expectation, so it is better to gzip that javascript file and compare that to the swf size. So to compare/test, in the past on windows I have used the 7zip application (I use 'normal' compression level, I don't know what is used on web servers). Hope that helps...

And the reason why PAYG was adopted If you don't want that overweight you must leave emulation and go with pure Royale, is a bit more work in the layout, but I think it's worth it.

Looking at the initial part of the HelloWorld.js with a text editor gives me an impression that most of the stuff in this file is never used.

So to expand a bit on Carlos’s answer, using emulation will probably cut down dev time but will certainly increase app size. If you are looking for the leanest solution that’s what Basic is for. Jewel is less focused on app size but will probably still be somewhat smaller than emulation. I don’t think we ever made precise measurements, but that’s the general idea. Hope this helps.

I'm not an expert on Flex emulation in Royale but it's trying to work as Flex did, so I think if original flex hello world was around 500kb is normal that emulation is around that size. Although Royale has a better architecture based on PAYG and strand/beads, only using UI Sets like Basic or Jewel will make you get better and lower sizes in your app. That's one of the tradebacks in using emulation vs a newer ui set you get it working with less changes in your code, but the size will be pretty similar I think.

Are there any compiler options available to minify the generated .js file? Any other ideas to minify it?
