Micro-front-end data integration method and device and basic framework based on micro-front end

The invention provides a micro-front-end data integration method and device. A specific embodiment of the method comprises the steps of obtaining an analysis result obtained by analyzing a project file; in response to a mapping relationship of only sub-applications in the analysis result, when an access demand for accessing the sub-applications exists, creating and mounting a system of the sub-applications through the micro-front-end main module, and displaying an access result of accessing the system by the user; in response to a mapping relationship between the sub-application and the component unit of the sub-application in the analysis result, downloading a unit file package of the component unit from the micro front-end sub-module, the unit file package being obtained by common agreement of the basic framework and the sub-application, and when an access demand for accessing the component unit exists, sending the unit file package to the micro front-end sub-module; and displaying the content related to th
