Page updating method and device and page processing method and device

The invention discloses a page updating method and device and a page processing method and device, and the method comprises the steps: carrying out the cross-platform isomorphic compilation conversionof a mobile application development framework RN on a local code through an isomorphic compilation plug-in when the local code based on a target project is compiled, and obtaining an RN executable file; storing the RN executable file into an offline file where a local offline resource file of the target project is located; and updating a local business page based on the RN executable file and thelocal offline resource file in the offline file. By utilizing the technical scheme provided by the embodiment of the invention, the cost of compatibility, manpower, time and the like of the RN technology landing in the existing H5 service can be greatly reduced, the original component of the client can be directly called in the existing H5 service, and the user experience is improved. 本发明公开了一种页面更新、页面处理方法及装置，所述页面更新方法包括：在基于
