Ideal Tips and Tricks for Angular App Development Process

Taking the advantage of ES6 features
In Angular, one of the JS versions-ECMAScript, gets updated with interesting features and functionalities in every release of Angular. ES6 is its latest version and has vital features available for efficient development.
  • ‘let and const’ instead of ‘var’: By making use of ‘let and const‘ rather than ‘var‘ helps you prevent the issues related to var. Developers can use ‘let‘in a normal situation and the value doesn’t get changed, then ‘const’ should be in its place.
  • Spread operator: ES6 also comes with a ‘spread operator’ (depicted by three dots (…)) and is commonly used for arrays; but can also help in some common tasks. It helps ‘iterable‘ that can be, sets, strings, arrays, etc. to spread in the receiver.
Naming conventions
Naming conventions improves the readability and maintainability to a great extent. It helps the Angular app developers to find the required code, filenames, folders, etc. faster and makes the understanding easier. So, follow the below-mentioned naming conventions, as indicated by the Angular style guide:
  • Use consistent names for all the available symbols.
  • In the descriptive names, make use of dashes for separating words
  • Follow a certain pattern that explains the features of the symbol first and then its type. The recommended pattern- feature.type.ts.
  • Make use of dots for separating the descriptive name from the type.
  • Also, make use of conventional type names like.component, .service, .module, .directive, .pipe, etc.
Maintaining the folder structure properly
It is of utmost importance to maintain a proper folder structure during Angular app development that can easily adapt to any modifications done during the development process. For instance:
— app
|– modules
|– home
|– [+] components
|– [+] pages
|– home-routing.module.ts
|– home.module.ts
|– core
|– [+] authentication
|– [+] footer
|– [+] guards
|– [+] http
|– [+] interceptors
|– [+] mocks
|– [+] services
|– [+] header
|– core.module.ts
|– ensureModuleLoadedOnceGuard.t
|– logger.service.ts
|
|– shared
|– [+] components
|– [+] directives
|– [+] pipes
|– [+] models
|
|– [+] configs
|– assets
|– scss
|– [+] partials
|– _base.scss
|– styles.scss
Using state management libraries
In Angular, state management is useful for the management of state transitions as it helps store the state of any kind of data. Several state management libraries like NGXS, NGRX, Akita, etc. are available and they come with different usages, purposes, states, etc. Amongst all of these, NGXS is one of the most widely preferred libraries since it has an easier learning curve and is highly stable as compared to others.
Using the right operators
Using appropriate operators in Angular is essential for various situations, especially when the flattening operators are used with the observables. So, follow the below ways for this:
  • Try to use mergeMap for handling all the emissions concurrently if you are willing to handle one emission after the other goes for concatMap.
  • Try to use switchMap when you want to ignore the previous emissions because of the new ones.
  • For canceling the new emissions, try using an operator called exhaustMap.
Utilizing service workers for a responsive app
Service workers are especially helpful in making the apps interactive and responsive. They help in converting the SPAs into PWAs by integrating native features into them. They help in providing a native experience to the apps. They help in caching the version completely when the web pages are refreshed. Service workers also load the new or latest cached code in other tabs. They also download resources when the content is changed. Service workers can be used with any version of Angular above the fifth version.
Isolation of all the API hacks
For fixing the bugs and issues in the APIs, it is essential to have the hacks in components and also to isolate the API hacks in one place. This will help in keeping the hacks close to the API and thus, minimum code will have to deal with the un-hacked code. It also helps the Angular developers to find these hacks easily while fixing the bugs.
Using Smart vs. Dummy Components
Separating the smart and dummy components is another important practice that every Angular app development company should follow. Dummy components are utilized only for presentation purposes, so they do not know where the data comes from. In such scenarios, using smart components that can inherit the presentation logic of dummy components is the best approach.
Ensuring proper documentation as much as possible
Last but not the least, it is a great practice to document the code, methods used, variables, etc. wherever possible. This helps other Angular developers to understand the logic and purpose of the code; which in turn improves code readability and management. Also, documenting the role and the applications of every variable and method is a good practice. For methods, every single parameter needs to be defined with multi-line comments specifying in brief about the tasks that the method accomplishes.

Key Takeaways:

Every release of Angular comes with some exciting features that the developer community and the Angular app development companies must be aware of. These will help in proactively avoiding blunders during development and keeping the applications bug-free.

The role of AngularJS Development in Crafting Responsive Web Apps!

The role of AngularJS Development in Crafting Responsive Web Apps!
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 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 web app 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.
AngularJS 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 is the experts’ choice for building responsive web 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, orderby, 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 AngularJS 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:
