Abstract: A data processing method includes: acquiring, in response to an opening request for a target application page, a first component compilation file of an instant display component depending on the target application page, and acquiring a second component compilation file of a placeholder component, the placeholder component being configured to hold a place for a time-use display component of the target application page; rendering and displaying the target application page based on the first component compilation file and the second component compilation file, the rendered-displayed target application page containing the instant display component and the placeholder component; and asynchronously replacing the placeholder component in the rendered-displayed target application page with the time-use display component according to a third component compilation file of the time-use display component. With the present disclosure, the speed of starting the target application page may be increased.
