Angular 10- Top Features and Modifications that You Must Know!

Angular 10- Top Features and Modifications that You Must Know!
Angular 10 updates
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:
Angular 10 features
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 Inlining 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 entrypoint 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.
With this, we come to the end of our topic. We hope this blog was knowledgeable and helpful to you!

Top Angular App Development Blunders that can Ruin Your Project

Top Angular App Development Blunders that can Ruin Your Project
Angular app development company
Angular is one of the most popular JavaScript frameworks, which offers myriad benefits to businesses worldwide. Most businesses prefer using Angular for mobile app development. Numerous giants in the corporate world have used Angularjs app development services for a wide range of projects. Take a look at some examples:
  • Video-streaming applications like NetFlix and YouTube
  • Online Payment application like PayPal
  • Travel application like JetBlue
  • A User-review application like GoodFilms
  • eCommerce applications like Land send, iStock, etc.
  • Job-portal like Upwork
Moreover, it is being predicted that Angular’s demand is going to rise further in the coming years. We can see that Angular’s future looks bright.
But despite the ever-increasing demand and popularity, there are some flaws in this framework like any other framework As such, developers tend to commit certain errors that may ruin your project. So, Angular developers and Angular development services must be aware of these common development blunders so that they are able to create top-grade applications.
In this blog, we have outlined the most common mistakes committed by Angular developers during the mobile app development process. So let’s get started.

Noteworthy Mistakes that Angular Developers tend to commit

Angular app development

Direct Manipulation of DOM

Another blunder that the developers tend to commit is making the changes directly in DOM. While changing the titles in pages or adding images, some developers may make modifications directly in DOM. But it is considered a bad practice. The DOM is a browser-specific API. 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 Tools

This 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. It affects project management, error handling in the project, the performance of the end product, and much more.

Improper Code-organization

In Angular, organizing the code into small chunks is considered beneficial as it simplifies the development process and also helps to track any errors and resolve them easily. This approach is much useful when several developers work on the same project. But since this framework uses MVC architecture, at times the developers may add excessive code to a single controller. Such an improper distribution of code may create issues in the later stages of development.

Cleaning up the Subscriptions

Unsubscribing to the unnecessary and older subscriptions is also a vital step in Angular development. The developers must clean up such subscriptions from time-to-time as these can cause a threat to data security and lead to several other issues. They should also avoid new subscriptions constantly.

Declaring Functions Incorrectly

Sometimes, the developers fail to assign the functions to a specific variable. In such cases, the code is at risk of being manipulated. So, it is essential to properly declare functions to the variables. It provides the following benefits:
  • Makes the code neat and maintainable
  • Allows easy splitting of files
  • Eases out the testing and maintenance process

Not using the controller AS Syntax

For assigning a model to the controller object, usually, the developers use $scope. But injecting the scope isn’t the right way to do it. Instead, using the controller As syntax is quite an effective and comparatively simpler method. Also, this syntax can be used in multiple ways in app development. But this syntax also has a drawback, that it provides confusing results while handling various nested scopes.

Unnecessary Use of jQuery

jQuery is commonly used for event-handling, for AJAX operations, and for making DOM manipulation easier. But it is advisable to first use the features available in Angular to the fullest and then use jQuery if required. Developers tend to first prefer jQuery without exploring options in Angular and this may result in unnecessary complications.

Improper Scope Binding

As we know, Angular uses the MVC model. Here, the scope is a set of built-in objects that consists of app data. Scope binds controller and view in the MVC model. At times, developers don’t follow the scoping rules provided by Angular which may result in issues in the app development process. The developers must properly assemble their scope objects.

Not using the Extension- Batarang

Batarang is a highly advantageous Google Chrome extension that aids in development as well as the debugging process. But this extension is often ignored by the developers and not used to its fullest potential.

Putting too many Tasks for the Controllers

In the hurry to meet deadlines, developers may mix logic layers and allocate more tasks to controllers than necessary. This can result in a code that will execute more functions for a certain situation and may end-up in performance issues. For instance- having several event handlers or performing AJAX calls in controllers.

Ignoring Pre-launch testing

Needless to say, it is imperative to do adequate testing before an app is launched in the market. The app should be tested in cross browsers and different environments using tools like BrowserStack or LambdaTest if required. This helps in identifying the bugs if any. These bugs can be worked upon to deliver a successful app. Failing to do so can reduce the success rates to a large extent.

A few more Considerable Mistakes in Angular Development

  • Failing to use the event-handlers properly
  • Not optimizing the Angular app
  • Using the Isolated scope directives more than required which results in several errors.
  • Using more Watchers than needed.
  • Heavy processing that can lead to a frozen browser.
  • Overusing the Resolves that can increase loading times and slow down the app.

Final words:

In an Angular development company, it is quite normal for the developers to make some mistakes while building apps. Sometimes it is due to negligence, sometimes it is due to lack of experience and sometimes it is due to pressing timelines. Even experienced Angular developers tend to make critical mistakes at times during Angular mobile and web app development. But the knowledge of these errors and mistakes in advance can curtail them to a great extent and lead to time-saving and better app performance as well.
