14 de ago. de 2023 · The router makes use of lazy loading to load child views only when the parent view is activated. Similarly, you can build custom elements that can be loaded into an Angular application when needed.
The lazy loading API for NgModule s (loadChildren) creates a new 'module' injector when it loads the lazily loaded children of a route. This feature was often useful to provide services only to a subset of routes in the application.
This is the archived documentation for Angular v17. Please visit angular.dev to see this page for the current version of Angular.
In this tutorial, you build upon a basic router configuration to explore features such as child routes, route parameters, lazy load NgModules, guard routes, and preloading data to improve the user experience.
If the tab contains several complex child components or the tab's contents rely on DOM calculations during initialization, it is advised to lazy load the tab's content. Tab contents can be lazy loaded by declaring the body in a ng-template with the matTabContent attribute.

Angular uses an injector system to make things available between modules. In an eagerly loaded app, the root application injector makes all of the providers in all of the modules available throughout the application. This behavior necessarily changes when you use lazy loading.
Lazy loading speeds up application load time by splitting the application into multiple bundles and loading them on demand. To use lazy loading, provide the loadChildren property in the Route object, instead of the children property.
24 de oct. de 2023 · For large applications with lots of routes, consider lazy loading —a design pattern that loads NgModules as needed. Lazy loading helps keep initial bundle sizes smaller, which in turn helps decrease load times.
By isolating your AngularJS application to a separate bundle, you can take advantage of lazy loading to load, bootstrap, and render the AngularJS application only when needed.
