So, it is important to do away with unnecessary change detection.Compatibility issues may arise when the apps don’t match the rules and regulations of the migrated technology.In this case, try to get rid of the unwanted mathematical recomputations by eliminating them from the app.Heavily loaded data streams may cause sudden pop-ups in the Angular apps.For such issues, reducing the size of the bootstrap logic is advisable.Tips to boost an Angular app’s performanceIdentification of Performance issues employing Chrome DevToolsAny performance issues in the Angular apps need to be identified first.offline compilation, most of the code is compiled during the build process itself.Tree-shaking is enabled by default if Angular-cli is used.Usage of Fewer Watchers and Shorter Digest CyclesUsing many watchers leads to a longer digest cycle, thereby affecting the app’s performance.So, Angular app developers should possibly use fewer watchers and keep the digest cycles shorter.Disabling of Unnecessary CSS Class and Comment DirectivesSince CSS Class and Comment Directives take time to load and slow down the Angular apps, it is wise to disable them.
The Angular team has amazed the entire software fraternity by releasing updated versions at frequent intervals!This is indeed a dynamic move to eliminate the road-blocks encountered by Angular app developers, leverage the goodies of emerging technologies and, provide a rich UX to customers.Angular has as many as 10 enhanced versions to its credit!Amongst these, Angular9 is one of the versions that offer multifarious breaking changes.This article talks about the advantages of the Ivy Compiler of Angular9 and its crucial role in Angular app Development.Ivy Compiler of V9 in a nutshellIvy refers to Angular’s future-generation compiling and rendering pipeline.Thereby, the build times became quicker, proving to be a sigh of relief for the Angular app developers.Reduction of bundle sizeUnlike the earlier compiler View Engine, Ivy employs the tree-shaking technique to get rid of the unused code from applications.
We will be using Ionic4 and Angular for this project along with a third-party News API.Click here to get more insight into the benefits of using these technologies.Now let’s get back to the topic for which this article is meant for.Then the CLI will ask you to enter essential information such as the name of the project, the starter template, etc.Now press Enter for directing the CLI to start the generation of files and installation of dependencies from npm.After this, go to the root folder of your project and run the below-given command for beginning a live-reload development server.$ cd ./newsapp$ ionic serveYou will see your application from the “http://localhost:8100” address.This project will show two pages- home and list, out of which you need to delete the list page.Now, delete the “src/app/list” folder and then open the file “app-routing.module.ts” file.Now there will be three routes available as given below:an empty path that redirects to the /home route/home route that displays the home page/list route that displays the list pageRemove the last one.This enables users to open the side menu.Adding ThemesFirst, open the “src/app/about/about.page.html”.Now add a dark color to the content section and a primary color to the menu toolbar.For adding a theme to the homepage, open the “src/app/home/home.page.html” file and, accordingly modify the code.
For instance,Video-streaming applications like NetFlix and YouTubeOnline Payment application like PayPalTravel application like JetBlueA User-review application like GoodFilmseCommerce applications like Land send, iStock, etc.Job-portal like UpworkAlso, it is being predicted that Angular’s demand is going to rise further in the coming years.It may tightly couple the Angular app’s code with the browser and this won’t allow the developers to target any other rendering environment later.Lack of knowledge of Important ToolsThis is one of the basic requirements that an Angular app development company must look into the developers while hiring.Effective usage of the available development tools in Angular like Protractor and TestWhizin Angular helps in successful project development.Lack of knowledge on any of these tools or inability to use them can result in critical issues sooner or later.Such an improper distribution of code may create issues in the later stages of development.Cleaning up the SubscriptionsUnsubscribing to the unnecessary and older subscriptions is also a vital step in Angular development.It provides the following benefits:Makes the code neat and maintainableAllows easy splitting of filesEases out the testing and maintenance processNot using the controller AS SyntaxFor assigning a model to the controller object, usually, the developers use $scope.Here, the scope is a set of built-in objects that consists of app data.
Today, Angular has as many as 10 updated versions to its credit and no one can deny its valuable contribution in architecting distinctive applications.Most of the Angular end-products have created a buzz amongst users owing to their uniqueness and had set a trend in themselves.It goes without saying that Angular app development has helped several start-ups as well as established businesses to grow exponentially.My write-up gives you a peek into those Angular applications that have garnered unprecedented success and have become a part and parcel of our daily lives.The most popular end-products of Angular app developmentAngular app development services turn out to be a one-stop solution for designing handy mobile and web applications.Lately, the multilingual-feature has been introduced, on account of which Gmail can be operated in 105 different languages.YouTubeThe most trending social media platform YouTube owes its success to Angular development.This platform not only enables its users to watch and post videos but also to share videos with millions of global users.NetflixNetflix is the most sought-after platform for watching our favorite movies irrespective of the time and location.So, this platform not only helps the freelancers to find work but also aides the entrepreneurs to find the desired resource for executing their task in much lesser time.
