I clicked the download button and noticed 70+ MB file. I thought to myself, why in the world a text editor needs to be so huge. And then I see your comment. I clicked on the Pause button on my download.
They have their own version of Chromium called Electron. But I recommend nwjs instead, witch is also built on Chromium and nodejs. And lets you make packages that only include your source code, so that you don't have to download the "browser" for every app.

You probably want to include an "install" script that:
* Download and install nwjs if it doesn't exist
* Make the "package" open with nw.exe
* optionally: Create a shortcut to the "package" on the desktop
* optionally: Set a icon for the shortcut
It's also packing a full browser, don't forget that. And likely all sorts of assets.
I particularly don't care. I'm more interested in how it performs during use.
By the way, task manager indicates it's using less then half that of RAM, with a few tabs open.
