I am new to programming and currently I managed to develop a Electron Desktop Application. I needed advice about, where can I host the database of my electron application (for free, as I am okay with the limitations on free hosting platforms) so that if in future I create a Android Application for the same then I would use the same database there as well.
I would recommend looking into mongoDB. It works well with Node. Any time I am building any type of Node stack, Mongo and Mongoose are my go-to. They are free and easy to install / use.
