I do not know if it's the right section, but I have a curiosity.
I tried to create an executable file with NW.js and with Electronjs. Both for Windows 64bit. I used KiwiStory as a starting point, without modifying anything (I just added a ico file). I setted to true the option Deduplicate images, Recompress images and Minify script.
For NW.js I used this tutorial. For Electronjs I used this instructions to download a zip files with the HTML and JS source. Then I created an electron app that reference to index.html like start page. This is a github with my code.
And this is the two files I obtained (hosted on GitHub)
As you can see, the NWjs export is 77MB (compressed), the Electronjs export is 47MB. If I decompress the NWjs's file I get a folder of 154MB. Electronjs is 3 times smaller than NWJS.
Instead the used RAM is similar:
So, why is the size difference so big?
Another question, from a noob.
Many applications have been built with electronjs. I myself use some of these (Gitkraken and Atom and Skype). Why does Scirra / Construct prefer NWJS? Are there any features that are missing at Electron?
