Angular Development has emerged as one of the most prominent technologies for mobile/web application development. It is developed and managed by the google team, so there’s no doubt about its popularity. In spite of the fact that the angular developers are efficient enough to develop web applications, they need some best practices to ensure the web applications’ performance and speed. To make the Angular web applications user friendly and super-responsive, you must follow the best practices. Here we’ll see some best practices for angular web app development services. Before proceeding for the angular web apps let us see some important terms in Angular.

#What is DOM in Angular?
DOM stands for Document Object Model. Angular directives are used to bind the application data with HTML attributes and these are as follows-

ng-disabled
ng-show
ng-hide

#What is @component in Angular?
@components are primary building blocks in Angular UI. Angular components are the subsets of directives. Angular components are the combination of properties templates, style, selector and many other properties.

#What is lazy loading in Angular?
Lazy loading means delaying the object until it is required. It is a process of loading modules like images, videos and so on. The main aim of lazy loading in Angular is to improve the loading time by prioritizing modules and displaying required modules only. 

#Top 10 Angular Best Practices To Follow In 2020-
**1. Lazy Loading Feature Module-**
Use of lazy load modules can improve your productivity. It is an inbuilt feature in Angular that helps developers to load the thing which is required. For instance, when you use the feature, it loads the components and other things that you need and stop other unnecessary  files to get loaded. Let us see how it functions;

// app.routing.ts
{ path: 'not-lazy-loaded', component: NotLazyLoadedComponent }
Here the ‘LazyLoading’ isn’t in place and you will end creating huge and unnecessary heavy-sized applications. When you use ‘LazyLoad’ and it helps you reduce the size of the application by abstaining from unnecessary file from loading.

**2. Angular coding styles-**
Using coding standards helps to carry out smooth angular web app development. Most of the angular developers struggle with the bug issues and bug fixing while developing angular app. You can follow several coding styles for better results like user-experience and lesser number of errors and bug etc. It is preferred to use naming conventions for files with similar names such as-

Tws.component.css

tws.component.html

General naming conventions in Angular:
Separate files by using dots-
.service, .component, .pipe and .module are the different files where this naming convention can be applied to reduce the complications.

tws.service.ts

Symbols and Filenames-
It is necessary to use filenames as per the symbols. For instance:

@Component({....})
Export class Tekkiwebsolutions { }
Tekkiwebsolutions.component.ts

@Directive({...})
Export class Tekkiwebsolutions { }
Tekkiwebsolutions.directives.ts

@NgModule({....})
Export class AppModule { }
app.module.ts
