Ehi, ciao
I don't know how to write apps in electron, but yours is an interesting project, just a few weeks ago I tried to run vscode on tinycore (successfully), and then I tried to run it in chroot (unsuccessfully).
But then I succeeded with docker and found that the minimum dependencies for vscode are
Xlibs nss gtk3 libasound libcups, does this also result to you only with electron?
Looking at your "default-remaster" file shows that the dependencies you used are these:
bash remaster.sh Xorg-7.7 openbox aterm nss gdk-pixbuf2 gtk3 libasound libcups libxkbcommon
Il I remember whell, gdk-pixbuf2 is a dependency of gtk3, I don't know about libxkbcommon, but this seems a keyboard library.
If you want to run you project also on docker, you can check my recent topic:
http://forum.tinycorelinux.net/index.php/topic,25090.msg160376.html#msg160376If you want, you can also make a smaller iso by booting electron fullscreen without any desktop manager (there is a recent program by user "rich" on the forum to do this)
