We are trying to provide a list of methods that can help us build faster Angular apps and monitor their performance. Our focus of this post is on decreasing initial load time and speeding up page navigation using code-splitting and preloading.
There are numbers of practices we can apply to shrink our App. Two of the most popular ones are:
Dead code elimination
The Angular CLI has been doing a great job minifying bundles and eliminating dead code. Code-splitting is entirely in on Developers hands. So contact Synthesis Technology “your Angular Development company” & hire Angular Developers…
Following approaches can be applied as per as your requirement….
Code-splitting with Angular
There are two main approaches to code-splitting
Route level code-splitting – In route-level code splitting, you encapsulate the functionality of each route into a separate chunk.
This is Built-in strategy that preloads all the modules in the application. Preloading modules in Angular is very similar to lazy loading, with the exception that the modules will be loaded immediately after all the eager loaded modules are ready
The problem with this approach is that in an application with many modules, it may increase the network consumption and also block the main thread when Angular registers the routes of the preloaded modules.
For larger apps, You can apply more advanced preloading methods like
To monitor Angular apps over time, the CLI supports performance budgets. The budget allow us to specify limits in which the production bundles of our app can grow. In the workspace configuration > budgets section, you can specify several different types of budgets.
When Looking at datasets of a lot of Angular apps running into the wild, we noticed that over 20% of them do not use content compression. Even more, don’t use a CDN. These are two ways that are very simple to implement as part of the deployment pipeline.
A highly efficient build of your app using the build functionality of the CLI
Components are a logical piece of code for Angular JS application. A Component consists of the Template − This is used to render the view for the application. This contains the HTML that needs to be rendered in the application. This part also includes the binding and directives.
