Enhancing the efficiency of Angular applications

My angular application is currently coded in a single app.module.ts file, containing all the components. However, I am facing issues with slow loading times. Is there a way to improve the load time of the application while keeping all the components within the declarations array? I have already tried removing some components from the declarations array and observed a significant improvement in load time, but ideally, I need all the components to be included. Are there any alternative solutions or optimizations that can achieve this without compromising on component inclusion?

app.module.ts

//All imports go here...

@NgModule({
    schemas: [CUSTOM_ELEMENTS_SCHEMA],
    imports: [
        SatPopoverModule,
        RouterModule.forRoot([]), 
        BrowserModule,

        DatePipe,

    ]
})
export class AppModule {
    constructor(public appRef: ApplicationRef) {
    }
}

  1. To enhance readability, consider organizing all Angular Material components into a separate module by creating a material.module.ts file. This way, you can easily import and export them only to the necessary modules using angular tree shaking for optimized performance.

  1. Implement lazy loading by analyzing the initial load of your application. Identify components or modules that are not needed during the initial load and segregate them into separate modules. Then, use lazy loading through routes for improved efficiency.

If you are utilizing Angular 12, you will notice enhanced naming conventions and more meaningful chunk data names.

  1. Edit the angular.json file to optimize build time. Check if any options like optimization: false, aot: true, buildOptimizer: false can be toggled on/off to expedite the build process. Customize these configurations as needed for specific builds.
