The page transition diagram is a function to make the positional relationship of each page visually easy to understand by creating a diagram of the page transition, but in the case of SPA (single page application), each request (HTTP (S) communication) is considered to be JSON format, and there is no page transition in general.
For that reason, it is considered that such apps are not suitable for the use of page transition diagram.
By adjusting the positional relationship of each request manually, it is considered possible to create page transition diagrams and use mechanical scaninng settings (bulk settings). However, if there are values that should be handed over in JSON format parameters, it is difficult to be done by "bulk settings", so reccomend to use "Handler".
For the basic scanning method by Handler, please see "Quick Start" manual.
