Just as a semi-related cleanup, you could also use the more correct headers for rebuilding the native deps

-    # taken from https://nixos.org/manual/nixpkgs/stable/#javascript-tool-specific
-    mkdir -p $HOME/.node-gyp/${nodejs.version}
-    echo 9 > $HOME/.node-gyp/${nodejs.version}/installVersion
-    ln -sfv ${nodejs}/include $HOME/.node-gyp/${nodejs.version}
-    export npm_config_nodedir=${nodejs}
+    export npm_config_nodedir=${electron.headers}

(I'm not sure what the first few lines actually achieved, it seemed to work without it)
