Found the solution:

    var app = new Framework7({
        on: {
            routerAjaxStart: function(xhr) {
                this.preloader.show(); //preload here
            },
            routerAjaxSuccess: function(xhr) {
                this.preloader.hide(); //preload close
            },
        },
    })
