The process is actually quite simple. Basically, we have developed an Electron app that creates a browser window, starts the web application and then loads the editor. To start the web application, we use Node’s Child Process API to execute the script that you used to run previous versions of Minium Developer.
If you want to know more, you can take a look at the code at https://github.com/viltgroup/minium-developer.
Nevertheless, you still can run Minium Developer from the browser as before. To do it, run the executable from the console and pass it the
--browser option. The same executable is now also used to run Automator projects. See the documentation for detailed instructions on how to do so.
