Running a server app and pointing your browser to it may work for you. Less sophisticated users will struggle with this approach starting with coordinating two things. You are also getting some bundling advantages with it - in particular electron contains node (and the right version with which the app was tested) which is also not a given on innocent users computers. Last but not least one gets support for building bundles for multiple OS platforms. Java apps on the desktop became more prevalent and usable when Java was bundled in. The Electron is not so different from what worked for Java.
