Could you describe given process to optimize NW.js package step by step?
Given article tells us about other case with 59.8Mb installer result. But you're speaking about 20Mb.
I didn't do anything that isn't mentioned in the article. I just took it to the extreme in every scenario.
In a more real world scenario the installer would be closer to 60 MB, and the installed version would be closer to 110MB. Ultimately, there is only so much you can do while shipping a copy of Node and an entire browser to your user. If filesize really is your greatest concern, then browser-based desktop apps aren't the way to go. I've compiled a list of alternative tools with pros/cons at XPDA.net
You could get it even smaller, probably well under 10mb with neutralino.js.org/
Neutralino is a neat little tool. It would certainly work in this simple app example. It has a lot of drawbacks though and you'd be better off with something more fleshed out. Even if your primary concern is filesize, there are plenty of other tools that produce very small packages with a better feature set.
