Angular development has become one of the best approaches for designing highly intuitive applications and when clubbed with a finely-tuned Ionic framework, the combination becomes all the more powerful and leads to the creation of beautifully designed user-centric hybrid mobile apps. This combination has already being used for countless projects worldwide. Consequently, Ionic and Angular JS app development services are highly being preferred by diverse industrial domains for various applications.

So please read the following post to know more about these vibrant technologies and the benefits that their combination offers.

What is Angular?

Angular is an open-source framework maintained by Google. It is a client-side development framework and was developed by Misko Hevery, an engineer at Brat Tech LLC in 2009. The Angular framework was launched in 2012; the first version being AngularJS. This framework comes with a host of tools and libraries that enable the Angular app developers to easily create robust feature-rich apps for diverse client needs. Additionally, it helps in developing and testing the virtual platforms; and as a result, can be utilized for Enterprise apps. Some of the top features of this framework are:

Two-way data binding
Filters
Model View Controller (MVC)
Templates
Licensed under the Apache license version 2.0
Directives
Dependency Injection

What is Ionic?

Ionic is an open-source software development kit (SDK) that ensures faster and cost-effective app development of mobile apps, desktop apps, PWAs, etc. with the utilization of technologies like HTML5, CSS, SASS, etc. It was created on top of AngularJS in the year 2013 by Max Lynch, Adam Bradley, and Ben Sperry of Drifty Co. Thereafter, it has added the support for React and Angular; the support for Vue is still under development.

Ionic app development mainly focuses on the front-end. It is an innovative SDK that enables the development of top-grade personal and commercial apps. The development of Ionic apps is easier since the Ionic framework is simpler to learn and implement. Moreover, the Ionic App Developers enjoy working with this framework. The key features of Ionic’s are given below:

Platform Independence
Intuitive User Interface
Cordova Plugins
High Adaptability
CSS and JavaScript Components
Ionic CLI
Ionic View

Combined Benefits of Both Technologies- Angular and Ionic

One-Stop Solution for Several Platforms:

Earlier, the developers needed to create separate codes for Android, Windows, iOS, etc. But AngularJS and Ionic changed this scenario allowing the development of multiple apps with a single codebase. Such apps can be easily downloaded from the app stores and can be run on any platform or device.

Reusable App Logic:

Fusing AngularJS and Ionic enables the developers to separate user interfaces, system logic, and data models. This means that the developers in parallel can reuse the logic and also customize the UI for different gadgets and different platforms like iOS, Android, Windows, etc. This reusability of the app logic has made the process less time-consuming and less expensive.

Ionic’s Components and Features:

Creating innovative icons and splash screens is a challenging task, especially for hybrid app development. For developing splash screens, the developers have to consider several parameters like length, density, width, type of device, etc. Ionic is a native-style UI kit that comes with various amazing features and components for making the development process hassle-free. Ionic’s .png, .ai, or .psd extensions help in building two files that enable smooth development of icons, splash screens, etc., and aesthetically appealing designs.

Angular’s Three-way Data-Binding:

Angular allows three-way data binding which means it enables simultaneous updating of the data model, UI as well as backend data in a hassle-free manner. So, when the in-memory data and UI are in sync with backend service data, the chances of user data staying complete across the devices are much higher. This also means that in Angular, it is easy to take the users’ inputs, process the information, save it on the server, and hence keeping the user interface synched with the backend is much easier.

Testability:

Testing is the most essential process once the apps are developed. It is a complicated and time-intensive process. But AngularJS eases out the testing process to a certain extent due to the Dependency Injection (DI) feature. This feature lets the developers fetch the pieces of the code from anywhere and duplicates the code for testing purposes. This means that the real components are replaced for the ones that fake the functionality.

Additional Benefits of Ionic App Development:

Ionic plays a significant role in app development due to its potential in debugging, performance-boosting qualities, and the ability to create attractive UI. The Ionic developers can take advantage of $ionicConfigProvider elaborate transition, style, or behavioral pattern. It creates the elements as per the device’s layout and also abides by the guidelines while utilizing the elements on diverse devices. Also, Ionic apps are built in a modular fashion, hence it is easy to update and maintain the app.

Another noteworthy feature of the Ionic is the Command-line interface i.e. CLI. It enables the development, implementation, and testing of any application on multiple platforms using a single command. This improves productivity and saves time for developers.

Angular is one of the most popular MVC pattern MVVM frameworks of the 21st century. Developed by Google, Angular is significantly used for building dynamic mobile, web, desktop apps using TypeScript, and HTML. The initial version of Angular was Angular JS. AngularJS development had created ripples in the software world when it released. Furthermore, this proactive team kept releasing updated versions at regular intervals to keep up with changing times. Recently, its latest version Angular10 was released in the market which created a buzz in the software world.

But to meet the high-end requirements of modern-day users, it is essential to not only use the next-gen framework like Angular but also follow a certain set of standard development practices. So in this blog, we have enlisted some of the top Angular app development practices that developers can learn and follow. But before we get started, let us have a quick look at the benefits of following these practices, rather tips.

Noticeable Benefits of Following the Angular Development Best Practices

Helps in Creating a Clean Code
Aids in Maintaining the Coding Standards
Helps in Minimizing the Developmental Time
Ensures a Minimal Score on the Bugs and Issues
Ensures Improved Performance of the End-product
Makes Code Management and Debugging Easier

Highlights of the Top Angular App Development Practices

Rules to follow for Angular Coding Styles

Following certain standard coding styles instead of the common styles during Angular app development can ensure the writing of simple and adaptable code and a good user-experience. Here are the rules to be followed for Angular coding styles:

The code per function shouldn’t exceed 75 lines
The code per file should not exceed 400 lines
It is good to declare the values of variables with ‘const’ if those values are intact
While sharing feature area for all slider components, developers should use a custom prefix
You can use shortcuts for files with similarly naming conventions. For instance, you may use hero.component.ts|html|css|spec for naming different files with the same names
In case you usually prefix the names for database, table, field, etc., avoid this practice for Interface names like AbastractShape and iShape
Apply single responsibility symbol to services, components, and symbols since it allows to create a more readable and cleaner app format.

Best Security Practices in Angular

Security is of utmost importance in any application. In Angular, security lapses can result in a dangerous threats, for instance, cross-site scripting. This issue can result in the passing of controls on the client side resulting in the alteration of the web pages. For avoiding such attacks, the developers should be aware of some security practices in the Angular framework as mentioned below:

Maintain the Angular Libraries on Regular Intervals
Update Angular libraries for every new update from Google
Prevent the XSS cross-site security issues

For doing this, it is necessary to consider the measures like DOM sanitization service, Offline template compiler, sanitization and security contexts, context security policy, etc. These will help to keep the attackers away from client-side apps ensuring higher security.

Routing in Angular and related Practices to Consider

Routing in Angular is performed to either display or hide components as and when needed by the users. Routing makes the components available for the development process whenever required, thus reducing constant trips to the server. However, bad routing practices can result in disorganized Angular apps at some point. So, for ensuring these issues don’t exist, the developers need to understand some basics about adding templates and components into the app along with the appropriate functioning of the routes. Have a glance at the best practices concerning Angular routing:

Developing the routes module wise
Routing with lazy loading
Organizing routes guards
Lazy loading routes with Preload

Preventing Observable Memory Leaks

Unlike any other framework, Angular, too, has observable memory leaks. Observables are of great use in Angular as they help in streamlining important data. But at the same time, leaks in observables can cause critical issues in mobile app development. Please follow the below-mentioned tips to avoid these leaks:

Use ‘async pipe’: these are built-in attributes that come in handy when the developers need to mark the components for emitted values. Also, they unsubscribe automatically from observables and thus prevent unnecessary memory leakages.
Use ‘take(1)’: This is an operator that allows you to get the data just once and helps to easily avoid memory leaks.
Use ‘takeUntil’: This is another operator that should be used when you wish to monitor second Observables and destroy the subscription; once the Observables gets completed or emits the value; thus, preventing the Observables to be leaked.

Usage of Template Directive

In Angular, ‘ngFor’ comes as a built-in template directive and is used for building new templates in the applications for every item. So, the Angular developers can rather use ‘trackBy’ directive every time they use ngFor. So, instead of rendering the complete DOM tree, ‘trackBy’ will help in creating customized and unique identifiers for every item.

Utilizing the most powerful accessibility tool- Angular CLI

Angular Command-Line Interface (CLI) already follows all the standard practices during Angular app development. It eases out the development process. It helps to test, debug, maintain, and deploy the applications. So, the developers should use it for developing an initial-level structure for the Angular app. They must use Angular CLI for the generation of new modules, directives, services, components, pipes, classes, etc. while creating any files and folders, instead of doing it manually. The usage of this interface decreases JavaScript fatigue and complexity.

Here is a detailed blog on other vital tools used in Angular for creating an outstanding application.

A Few Other Recommended Practices

Naming Conventions for readability and maintainability
Maintaining the folder structure properly
Utilizing service workers for ensuring that the apps become highly responsive
Isolating all the API hacks in one place
Breaking down the larger components into multiple smaller components
Ensuring proper documentation of code, every variable, and the methods used
Using state management libraries for managing state transitions

In our upcoming blog, we will explain these practices in detail and also include some more tips and practices that all the Angular development services should follow. Also, here is our blog on the “Potential mistakes that developers must avoid during Angular development!”
