Micro front-end message communication method and device based on central message proxy

The invention provides a micro-front-end message communication method and device based on a central message proxy, applied to a main application in a micro-front-end architecture, the main application is registered as a central message proxy component, and the central message proxy component is used for opening a corresponding message communication interface for each sub-application; determining a message subscription request sent by a message communication interface called by the subscriber sub-application, and constructing relation mapping between the subscriber sub-application and a message theme type carried in the message subscription request; in response to a message publishing request sent by the message communication interface called by the message publisher sub-application, receiving a target theme message corresponding to the message publishing request; and broadcasting the target theme message to the corresponding subscriber sub-application according to the relational mapping.
