DevExtreme Angular - Link Modules
DevExtreme comes in pre-assembled bundles. dx.viz.js includes Charts, Gauges, Funnel, VectorMap, and other data visualization UI components. dx.web.js includes Grids, Scheduler, Form, and various editors. dx.all.js compile the previous two bundles. Bundles that include a particular UI component are listed on the UI component's overview page in the API reference.
Alternatively, you can use DevExtreme modules to import only the functionality you require. Unlike the bundles, modules are compact and can be loaded on demand. This optimizes memory consumption and speeds up your application.
You can create a smaller bundle from modules using Webpack or load modules using jspm or RequireJS.
