Utilizing the Angular framework for building an app is immensely beneficial. Nevertheless, coding in Angular can turn tricky at times, thereby adversely affecting the code quality. Thankfully, there are certain tried and tested strategies that will instantly improve the quality of your Angular codebase. This post provides Angular Development Company with detailed insights into these ingenious strategies. Take a look!

Key Strategies that Improve your Angular Codebase

Strategy 1: Adhering to the Standard Practices established by the Angular Team

The Angular framework clearly defines a set of rules and practices that one should follow for creating a uniform codebase across the organization. Adhering to these Angular app design guidelines proves beneficial in the following ways:

Increases the uniformity of the code, thereby enhancing its quality

Makes the app easier to comprehend

Allows developers to speedily integrate into a new team owing to high familiarity with the code

Example: Take a look at this particular example of Angular design guideline

Naming Files:

Angular files should follow the naming conventions recommended by Angular team like each file with an Angular structure such as a pipe, a module, or a component is named in the following manner:

[Name].[structure].[file-extension]

Hence, for creating a component that is to be displayed to the customers, name it as ‘customer’ – its structure will be a component and the file extension will be ‘css’, ‘.ts’, or ‘html’ – Custumer.component.ts

All the aforesaid functions are taken care of by the Angular-cli by employing a command – ng-generate – for creating the structure, and the file that is created as an outcome of this function follows the naming convention automatically.

Strategy 2: Bundling the code into Modules

One of the commonest mistakes developers commit is placing everything into the application module resulting in a complete mess. Therefore, it is advisable to employ modules and structure those modules as defined by the Angular team. The usage of modules ushers in the following benefits:

Enables you to organize the code into small bundles/ chunks

Enhances the code’s readability

Allows one to effortlessly find errors while troubleshooting

Enriches the UX by downloading only the parts that need to function

Key Modules in the Angular framework and their Functioning

Feature Modules:

Feature modules are created in a different folder named ‘feature’ and are meant to contain a particular feature. For instance, the feature-module for the attribute named ‘feature’ is placed within a directory called feature and the module file follows the naming convention – feature.module.ts.

The top advantages of using feature-modules are as follows:

Enable structuring the code in an easy way that can be clearly understood

Allow complete separation of various features to avoid any weird overlapping that may cause confusion and potential bugs

Enable the usage of lazy-loading – a technique that makes it possible to download only the required module to the client’s device instead of downloading all modules. For instance, there’s no need for serving the code of the administration section for a blog to every user who visits the site. Instead, the admin-section can be separated into a feature-module and load it through lazy loading. So, the users now have to download the code for the blog-section only; the extra JavaScript code has to be downloaded by those users who wish to navigate to the admin section.

Core/Shared Modules

Why is Core/Shared Modules required?

Feature modules encase every directive/component/pipe into a separate module and so it cannot be used in other parts of the app if it is not imported. While such a function is immensely useful in certain situations, it doesn’t work for other cases. For instance, when there is a need to import the admin-module of the blog section for using a plain utility-directive, employing a feature module will complicate things and also overshadow its advantages. In such a case there arises a need to employ modules like ‘Core’ and ‘Shared’ for addressing other requirements. Check them out!

Shared Modules

Shared modules need to be used when pieces of your app are required to be used across multiple features/areas of the app. Therefore, components that are reused in multiple features are called shared modules like services and pipes. With shared modules, you can share common pieces for filling out feature module ‘sections’. All feature modules use shared modules without having to break the encasing of other modules. Example - A text-formatting module containing a set of pipes for formatting text in a particular way.

Core Modules

Core modules are encased within the CoreModule inside a directory named ‘core’ and are used for placing app-wide services that have been used only once.

This module provides all application-wide singleton services that may be required. It is imported into the application module and keeps the app module nice and tidy. Nevertheless, the core module is not limited to services only. Everything that is used app-wide, but isn’t suitable for a shared module can be executed using the core module. Example: Loading-spinners at the beginning of the app are not used elsewhere in the app and so building an additional shared module for this purpose would be an over kill.

Private Services within Components

Most Angular services are meant for functioning globally and are thereafter provided at an app-level called the App Module. But this strategy is useful only if you need the global-singleton pattern wherein a single global instance is needed if your service requires to cache things. In other instances, each component comes with a separate cache on account of Angular’s scoped dependency injection.

But, there are several services that do not require to be provided globally, particularly if used by a single component. Here, you need to provide the service within the component – a service that is directly attached to the component. You can also provide the services in a module that is accessible from anywhere it is required. For this reason, the services are related to features/feature-modules and hence they become easier to locate as well as understand in the correct context. Moreover, these are contained by a feature module that enables lazy-loading abilities. Furthermore, it reduces the risk of a dead code when the only module using that service is deleted.

Strategy 3: Keeping Logic outside your Components as a Separate Service

Keeping logic outside your components is a good strategy for improving the code quality. But why should the business logic exist as a separate service? The reasons are manifold.

Firstly, conducting testing for components and UI is quite challenging as compared to conducting pure logic testing and secondly, this strategy enables you to create more efficient tests at a fast pace. If available as a separate service, your logic can also be used by other components. This way, more amount of code can be reused minimizing the need for writing codes altogether. Furthermore, the code can be read effortlessly, if the logic exists in a separate file.

Strategy 4: Ensuring the Accuracy of your Asynchronous code

Angular’s environment involves stringent rules for achieving code consistency and this is applicable for the asynchronous code as well. The rxjs library is employed for every asynchronous function and this library utilizes the observer pattern. The following piece of advice will help you in ensuring the accuracy of the asynchronous code.

Developers are often confused on which promises to use – The promise that enables using the TypeScript await operator or the powerful rxjs-observables? Remember that it is advisable to use the one suggested by the Angular team - rxjs-observables.

Using rxjs-observables is complicated and if used improperly serious bugs may appear. The commonest error is not unsubscribing from the observable leading to memory leaks, unwanted calculations, and alterations in your app. In order to avoid this mistake, it is advised to use the async pipe as this pipe automatically unsubscribes from the observable after the component is deleted.

Strategy 5: Centralized State Management

The larger the application, the lower is the code quality. This is because since every component has its own state, the presence of hundreds of components becomes confusing and makes debugging all the more challenging. This problem can be resolved by practicing centralized state management.

What is centralized state management?

Centralized state management is the practice of storing the entire app’s state in one single location rather than being scattered all over the application. Here, a single instance controls the overall state and executes changes to the state.

Benefits of centralized state management

It’s easy to find the state as it is present at one place and one need not have to search across the component tree

It is a single object that need not be acquired from multiple places and so simplifies transfer between apps

Problems arising during communication between components are solved as they react to state changes only.

Should you employ Redux/ngrx?

Using Redux is recommended while generating large apps containing multiple components. However Redux doesn’t work well in the case of small and mid-sized apps because it involves a host of boilerplate code that can over-complicate the code of the Angular application.

In today’s digital era, websites turn out to be powerful means for promoting a business. A business without an online portal is like a bird without wings! Business organizations using web apps to sell their services or products; succeed in creating a profound impact on consumers. Nevertheless, a web app must also be responsive. The responsiveness of a website depends on the following aspects:

The time taken for initial loading

The speed of transition between pages

The app’s capability to adjust and adapt to the screen sizes of diverse electronic devices.

Robust and responsive web apps result in happy and loyal customers!

Choosing an effectual app development framework; plays a key role in building a responsive website, capable of capturing the market. Most technical experts of the software sector will vouch for Angular JS to be one of the best choices for responsive web application development. AngularJS was launched by Google in 2009 as an open-source framework based on JavaScript, HTML, and CSS; for developing exemplary web applications. Ever since then, this remarkable framework has survived all odds and retained its goodwill even to this date.

Angular JS App Development is credited to have architected responsive enterprise apps for many significant brands like Netflix, PayPal, Lego, Weather, etc., and helped them to earn fame and recognition. This blog discusses the reasons why Angular JS web application development services is recommended by experts for building responsive applications.

Reasons to choose the Angular JS framework for Responsive Web App Development

A hassle-free Web app Development Process

Crafting web applications with AngularJS turns out to be a hassle-free process because:

Angular development depends on HTML alongside JavaScript and so, interactive web designs can be easily created. Therefore, more tasks are executed with lesser coding, saving time, and effort of developers.

Doing development in AngularJS is effortless if the Mobile App developers have prior coding experience of using other JavaScript frameworks such as JQuery, Backbone.js, etc

It accompanies ng-class and ng-mode which are a part of the usual tasks in JQuery.

Angular app developers have to just write a few lines of code for executing the tasks of two-way data binding and saving.

Design creation benefits

AngularJS developers can use the option of Markup to identify elements in a document without the need for breaking the whole app. Specific parts of the code are re-organized to serve this purpose.

Code reusability

The feature of code reusability is one of the upsides of AngularJS. It helps to architect responsive, complex, enterprise-level web apps; reduces the time-to-market, and eases out the implementation procedure.

Availability of Filters

The AngularJS environment offers various filters for uppercase, lowercase, numbers, order by, date, currency, etc. that help developers to transform the data that is stored in the Angular JS responsive design. For creating their own filter, developers need to register a new filter factory.

Enhanced programming

AngularJS offers some ingenious features that enhance programming practices. For instance, Angular directives support reusable components. Moreover, the REST API connection to the servers consumes lesser bandwidth, thereby allowing HTTP requests to efficiently handle data.

Full utilization of the existing data

Unlike many other frameworks, AngularJS does not pose any restrictions regarding the management of underlying data. The users of Angular JS apps can access the underlying database as these apps are implemented using RESTful APIs. In case one is using internal APIs, the existing front-end code can be replaced by employing an Angular app and hence the server-side security can be re-used effortlessly. Apps built using web app frameworks like Django, Rails, etc. can also be easily replaced by Angular apps using directive-based implementation to improve the website’s performance.

A secure access management process

Whenever businesses plan to upgrade an application for leveraging the benefits of Angular they are doubtful whether Angular would be able to utilize the existing security strategies meant for maintaining the level-of-access restrictions that have been mandated by departmental regulations. Thankfully, due to the flexibility of the Angular eco-system, a plethora of options are available that enable developers to merge the existent domain systems into the app-login and its security flow. However, AngularJS being a front-end inclusion, one needs supplemental libraries like Idapjs to reap the benefits of the aforesaid functionality. An interaction between AngularJS and these supplemental libraries enables implementing single sign-on. These libraries are utilized by integrating some code and conducting a security audit for detecting the presence of any vulnerability.

Parallel Developmental ability

The success of any responsive web app development project depends on the collaboration amongst the team members. The Angular environment simplifies collaboration between developers. The Dependency Injection eases out the process of script-sharing, and integration with the previously-created modules using Angular. Furthermore, the myriad libraries available, enable the imbibing of new features into projects.

Improved testability

A web app might require alterations in any stage of the developmental process, with a need to conduct testing for boosting performance and addressing issues. AngularJS development proves highly advantageous in such situations as it enhances the testability of web apps. Given below are the reasons for the same.

Its Dependency Injection finds out the areas that require testing.

The in-built Angular modules enable exhaustive testing for every module that is created.

Support for real-time testing is available.

The official Angular website provides ample documentation on testing methodologies.

Therefore, testing becomes effortless for developers working with Angular.

Maintainability of apps

Several maintenance issues like fixing bugs, adding new features, etc. crop up post-deployment. Fortunately, Angular web applications are quite maintainable. This is because AngularJS uses the model as the source, resulting in the creation of an object-oriented client-side design. The object-oriented design principles help to make the code more maintainable.

The Security quotient

Web apps being susceptible to cyber-attacks, it becomes quite challenging for enterprises to ensure their security. Angular JS development minimizes security threats to a considerable extent due to the reasons given below:

Usage of the HTTP interface in the form of a REST API or a web service for communicating with the server ensures safety.

The flexibility of the Angular environment permits the user to integrate Angular apps with third-party security systems.

The presence of a Dynamic Community

Being Google’s brainchild, the Angular JS framework enjoys the support of a Google-backed dynamic community comprising of experienced and highly proficient Angular developers. The community has been tasked to solve the queries of Angular app developers. It also arranges for conferences wherein software firms from all corners of the globe are welcomed to provide information regarding the novel innovations and progressions on Angular JS.

Final Thoughts:

Thus, the Angular JS framework decked up with efficient functionalities and productive methodologies prove to be an apt choice for crafting interactive, bug-free, and responsive web applications. Entrepreneurs hiring an Angular app development Company to build their website are sure to fly high and touch new horizons of success.

Ionic App Development

Angular, the TypeScript-based, JavaScript-compiled, Google-developed framework, has been prevalent in the software industry since 2009. Over time, this framework has proved highly efficient for developing intuitive and dynamic applications as required by diverse industrial sectors. Consequently, most businesses these days prefer Angular for app development. As such, increasing demand for Angularjs app development services has been observed globally. And this is obvious because, since the inception of Angular, it has come a long way releasing several advanced versions successfully in quick progression. AngularJS is known to be its first version and later, Angular 2, Angular 4, Angular 5, Angular 6, Angular 8, and Angular 9 were released. Recently, on 24 June 2020, its latest version- Angular 10 was released in the market. So let us explore this update in detail.

Angular 10 and its Value Offerings

Angular 10 update looks quite smaller than its previous versions but is an effective attempt of the Angular team to keep this framework relevant and up-to-date. This time, they have emphasized more on improving quality, ecosystem, and tools rather than new features. Every Angular App Development Company must be well versed with the top updates of this version. The noteworthy updates are as follows:

CommonJS import Warnings

CommonJS was originally meant for designing the server-side modules and not for reducing the production package size. When the AngularJS app developers make use of dependencies bundled with CommonJS, it results in larger code bundles and ultimately slow performing applications. But after this update, the developers will automatically be notified in case a CommonJS module pulls into your build.

New Date Range Picker

The new date range picker is another update in the Angular UI Material component library. The components mat date input range and mat date picker range can be used for using this range picker.

Optional Stricter Settings

Angular 10 comes with a stricter project set-up for the creation of a new workspace using “ng new”. Activating the flag- “ng new-strict” can initialize the new project just with a few settings. These settings enhance maintainability, enable the CLI to optimize the app functions in an advanced manner, and also help to identify the bugs well ahead of time. Also, the “strict” flag reduces default bundle budgets by up to 75%, changes template type checking to Strict, it selects strict mode in TypeScript, allows advanced tree-shaking to configure the app as free of side-effects, preventing declarations of type any by configuring linting rules.

Updates in JS Ecosystem

The Angular team has made a few modifications for keeping the framework synchronized and up-to-date with the JavaScript Ecosystem. For instance, TypeScript is updated to TypeScript 3.9, the static analysis tool for TypeScript- TSLint has been updated to v6, and the runtime library for TypeScript- TSLib has been updated to v2.0. They have also upgraded the project layout. There is an additional tsconfig.base.json file as well which provides enhanced support to the way build tooling and IDEs resolve type and package configurations. Due to these updates, every AngularJS app development company can leverage these functionalities to the fullest for architecting responsive, user-friendly, and customizable apps and other software projects.

Bugs Resolutions

The Angular team has focused more on problem-solving during this update. They have worked with the community and made bigger contributions this time as about 700 issues were completely resolved considering the overall framework components and tools. The issues of ranges in the parser, Terser In lining Bug, errors created due to migration when the symbol does not exist, etc. were fixed. Additionally, 2,000 more issues were touched.

Advanced browser Configurations

Browser configurations of Angular have been updated so that the new projects can exclude less used as well as older browsers like Internet Explorer 9, 10, Internet Explorer Web, etc. The Angular app developers can add the browsers that need to be supported in the .browserslistrc file, for enabling ES5 builds and differential loading for browsers.

Some Deprecations

In Angular 10, several unimportant sections have been removed. For example, the Angular Package Format doesn’t include FESM5 or ESM5 bundles anymore. This saves about 119MB of install- and download- time, while running yarn or npm install for the libraries and packages in Angular. Since any down-levelling for supporting the ES5 is performed at the end of the build process, these formats aren’t needed any longer.

Also, WrappedValue is deprecated. Probably, it will be removed in v12. WrappedValue was useful for triggering change detection even if the same object instance was emitted or produced. When WrappedValue is utilized, there is a performance cost and this functionality is useful in relatively rare cases. As a result, the Angular team may have decided to drop it.

Additional Features and Updates

The team has added a program-based entry-point finder- EntryPointFinder in Angular version 10. This is supposedly faster than DirectoryWalkerEntryPointFinder.

A compiler interface has been introduced during this update that covers the actual ngtsc compiler. With the use of the project interface, the language service-specific compiler can manage several Typecheck files while also building Scriptinfos as needed.

In Angular 10, the team has removed Autocompletion from HTML entities like &amp, due to certain performance issues and problematic value.

It is now possible to configure Async locking timeouts which adds support for the ngcc.config.js file. This sets the retryDelay and retryAttempts options for the AsyncLocker.

The team has also made type-checking performance enhancements to the compiler-CLI.

Angular version 10 supports the merging of several translation files. Before this version, only a single translation file was permitted per locale. Now it is possible to specify multiple files per locale for the users and with the help of messaging ID, the transactions from every file will be merged.

For performance improvement, the Angular team has made computation of basePaths lazy, so, the work will be performed in TargetedEntryPointFinder only if required. Before this version, the basePaths got computed as and when the finder got instantiated even though the entry-point was already processed. This was a waste of effort which has now been handled.

Urlmatcher’s type now indicates clearly that it can always return null.

Improved performance due to a decrease in the size of the entry point manifest and implementing a caching technique in the manifest.

Final Verdict:

With incredible features, some removals, and some modifications, Angular has enriched itself and become all the more powerful. Owing to features like data linking, reusing of web elements, tooling, etc. along with Google’s vibrant community support, the popularity of angularjs web app development and angularjs mobile app development has exponentially risen.

Traditional website designs fail to achieve the desired results any longer. Modern-day users expect websites to be not only intuitive and engaging but also visually attractive and decked up with rich features. One of the most befitting frameworks that satisfy this challenging requirement is Angular. Angular is an open-source JavaScript framework that came into being in 2009 and has been made future-ready by the release of frequent revamped versions by the Angular team, the latest one being Angular 10. This highly marketable framework excels in developing the creative components of a website and hence is a popular pick for website creators. Top brands such as Lego, PayPal, The Guardian, Weather, Netflix, etc. have leveraged Angular development services to build spectacular websites.

This article discusses the role of Angular in creating an engaging and visually appealing website design.

The role of Angular in creating an attractive and engaging website design

Have a look at the distinctive capabilities of Angular in the realm of web development!

Model-View-Controller approach

Angular’s MVC (Model View Controller) architecture splits the app into three distinct components – Model, View, and Controller. The Model maintains data, View displays necessary data and Controller acts as a bridge to connect View and Model. MVC approach eases out the task of Angular app developers while creating Single Page Applications and saves their time as well.

High Scalability

AngularJS development allows one to resize or alter components, modules, logical view, etc. through all stages of the developmental cycle. Therefore, the unidirectional flow is maintained even when developers create new functionalities or extend the existing logic.

Presence of Dependency Injection

Dependency Injection is a design pattern wherein an object bestows dependency on another object. With Angular, the dependencies run alongside their components and this enables the classes to obtain dependency from external sources. Consequently, a tree of dependency injectors is created which can be changed without the need to reconfigure its components. Moreover, owing to its hierarchical structure, it is clearly defined how alterations made to a certain element affects the function of other elements. Thus, this feature enhances performance and also speeds up development.

Lazy Loading

Lazy loading is a unique feature of AngularJS front-end development that enables asynchronous loading of JavaScript components when a particular route is activated. During this action, no other needless page or route is called for. The App Component is loaded as default by the app in the root URL, and the lazy module is loaded asynchronously when users navigate employing the command lazy/load-me.

Ability to create Declarative Interfaces

Angular’s ability to create a declarative UI, is another reason for its high adoption rate. Angular app development employs HTML in place of JavaScript to define the User Interface. HTML is much lesser complicated than JavaScript. Furthermore, owing to HTML usage, the UI components of an Angular web application gain intuitive and declarative properties. Hence, we do not need to manually create flows of the program, Angular’s declarative UI loads components automatically as per the defined page layout and the data. Therefore, the usage of Angular for building websites saves time as well as efforts of front-end developers.

Lightweight code

Since Angular is a framework, code is very precise. Development in Angular requires lesser coding as compared to JavaScript, CSS, and HTML. Moreover, the code is lightweight and readable.

SPA creation benefits

Angular is known for its capability to architect outstanding Single Page Applications as the Angular infrastructure supports journaling, routing, and template usage. Needless to say, SPAs possess a responsive web design and impart a native-like UX on the web.

Benefits of being a framework rather than a library

Angular is often compared to libraries like React.js, when talking about front-end development. But, since Angular is a framework and not a library; the set-up process becomes quicker which speeds up development. Additionally, the Angular eco-system possesses numerous self-libraries. Thus, Angular turns out to be far more beneficial than the libraries like React.js offering similar functionalities.

Ease of Testing

Angular’s capability to mock dependencies allows one to easily test any aspect of the web app starting from its User Interface to the business logic. Also, the separation of modules reduces testing complexities and makes it possible for the users to load only those services that are needed.

Community Backing

The Angular framework has been created and is being maintained by the tech giant Google. As such, the Angular community is equipped with detailed documentation that covers all aspects related to its usage and fixing of issues.  Moreover, the community organizes global conferences, and hackathons involving IT professionals across the globe. It also solves the queries of Angular developers through online forums.

Wrap up

In a nutshell, Angular is stuffed with technical goodies that help one to create enticing and engaging websites speedily and in a cost-effective way. So, hiring an Angular App Development Company or Angular App Developers would be a wise decision for those planning to create captivating websites.

Angular vs ReactJS are two popular front-end web frameworks.

For less-experienced developers, ReactJS may be a more reliable bet due to its comparative simplicity; however, AngularJS development offers a comprehensive solution to front-end development that could benefit large-scale projects.

The open-source JavaScript framework- Angular is one of the best picks for developing client-side web and mobile apps. Besides, the Angular team’s frequent updates to keep up with the ever-changing customer expectations have helped to maintain high standards in Angular applications. Consequently, several software magnates like Google and Microsoft have harnessed the benefits of Angular app development.

However, Angular apps turn out to be highly performance-based, only if the best developmental practices are adhered to. Also, once the app is live, if you notice a sharp decline in the app-visit traffic, a decrease in the engagement rate, and an increased bounce rate, it’s high time you must act to boost the performance of your Angular applications.

So, in this write-up, I have penned down certain tried and tested strategies to be adopted for boosting your Angular app’s performance.

Techniques to Resolve the Key Performance Woes in Angular Applications

If an app encounters frequent slowdowns, the users lose patience and abandon the app for another one with similar functionality. To resolve this issue, optimize your hosting by using PWA or static cache content.

Unexpected app crashes are likely when several requests are made to the server around the same time. To prevent this, one can slow down the HTTP response or utilize a quality service aggregator.

Needless server usage not only threatens an application’s security but also affects its performance. 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. This affects the app functioning and hampers the user experience. 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 performance

Identification of Performance issues employing Chrome DevTools

Any performance issues in the Angular apps need to be identified first. Performance issues can be detected at the earliest by employing Chrome DevTools like CPU Profiler, Timeline, etc. and then several ways can be employed to resolve them.

Improving Load-time Performance

AOT Compilation

In AOT compilation, i.e. offline compilation, most of the code is compiled during the build process itself. This reduces the processing to be done on the client browser.AOT will be enabled simply by specifying the ‘aot’ flag with Angular-CLI.

Uglification Process

This process involves minimizing the code size by employing different kinds of code transformations like removing white spaces and comments, mangling, etc. Specify the ‘prod’ flag for performing uglification in the case of Angular-cli and employ the uglify plugin for webpack.

Tree-shaking Process

The tree-shaking process involves the elimination of the unused code to reduce the build size. Tree-shaking is enabled by default if Angular-cli is used.

Usage of Fewer Watchers and Shorter Digest Cycles

Using 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 Directives

Since CSS Class and Comment Directives take time to load and slow down the Angular apps, it is wise to disable them. For this, use $compileProvider in your Angular project.

Loadash Usage

Installing and loading angular-loadash in your application will enable you to rewrite the code’s logic and then update the same within the built-in Angular methodologies.

Using Smaller DOM Trees

Accessing the DOM frequently slows the app down and adversely affects its performance. So, use smaller DOM trees and possibly, do not change the DOM.

Using Smaller Variable Scopes

Larger Variable Scopes too result in bad performing apps. Hence, it is advisable to use the smaller variable scopes. Also, if the variables are tightly scoped, the garbage collector can release memory occasionally.

Lazy Loading

Lazy loading involves loading only those modules that are needed at that instant, rather than loading the full app. This greatly reduces the initial loading time.

Usage of OnPush and Immutable Objects

Usage of OnPushminimizes change detection. OnPush means faster detection of values when the reference types are nothing but immutable objects. Immutable objects can be utilized for rendering the DOM and for reducing complexities.

Employing Web Workers for UI’s non-blocking

Functions like resizing of graphics, data encryption, etc. include the main thread. But these tend to freeze the UI and end up irritating the end-users. However, web workers can use such complicated functions while not including the main thread during the background processes and simultaneously, maintain a smooth UI operation. These web workers can be used in instances like executing complicated calculations, filtering images, formatting the content in real-time, etc.

Usage of Smart Tools to Boost Performance

Protractor: This versatile testing tool, created by the Angular team, provides high flexibility while testing applications.

Batarang: This debugging tool, also a brainchild of the Angular team, is a chrome extension that proves immensely beneficial to track performance benchmarks.

WebDriverIO, NightwatchJS, and TestingWhiz are few other outstanding tools.

Key Takeaway

Every Angular App Development Company and Angular App Developer must be aware of these best practices. These must be implemented properly during development as well as post-deployment to optimize the performance of Angular applications.
