jQuery/JS SPA Framework - HtmlApplication Deprecated

include spa-deprecated-note

An object that manages views and controls the application life cycle.

import HtmlApplication from "devextreme/framework/html/html_application"
Type:

Object

The HtmlApplication object connects markup elements, scripts and styles to a single application, and provides methods for controlling the application life cycle. To create an HtmlApplication object, call the HtmlApplication constructor within the document.ready event handler or the jQuery "$()" function.

JavaScript
$(function () {
    MyApp.app = new DevExpress.framework.html.HtmlApplication();
});

To configure the HtmlApplication object, pass a configuration object as the constructor's parameter. Specify the required options within the configuration object. For instance, specify the set of layouts to be used as a skeleton for application views. Using the application object, register a routing rule for the application and navigate to a starting view.

JavaScript
window.MyApp = {};
$(function() {
    MyApp.app = new DevExpress.framework.html.HtmlApplication({
        namespace: MyApp,
        layoutSet: DevExpress.framework.html.layoutSets['navbar']
    });
    MyApp.app.router.register(":view", { view: "index"});
    MyApp.app.navigate();
});
