Everyone knows Angular is one of the leading and most powerful Javascript frameworks. Therefore it is highly recommended for developing dynamic programming applications irrespective of their types such as native apps, web applications and single-page applications. It may quite interest you to know that the main objective behind introducing the full-stack front-end Javascript framework was to come up with a power-packed solution that is quite self-sufficient especially when incorporated with any popular Javascript framework.
The following post emphasizes on what are the Angular best practices to take into account. Each one of the below-mentioned practices is popular, carries a proven track record and has been performed by some of the most reliable and reputable Angular development companies across the globe. So whenever you wish to hire India based Angular experts, make sure you end up choosing a company that follows at least two of the below-mentioned Angular best practices. Before we jump in right there, it’s time to take a brief detour and have a better perspective regarding the Angular framework, how is it beneficial?
Introducing Angular Framework
Well, if you are looking for a prominent framework that works wonders in regard to robustness, scalability and high-end performance then within the blink of an eye, you should be choosing Angular. Angular is one of the leading open-source frameworks that has been developed as well as maintained by Google. Being one of the core aspects of the rich Javascript ecosystem, the Angular framework is highly recommended for developing numerous mobile and desktop applications. It may quite interest you to know that the initial idea of creating an Angular framework came from the concept of angle brackets (<>).
No wonder Google continues to use Angular for a wide range of applications such as Google, Cloud, Adwords, and not just that, several renowned names such as Samsung, Delta Air Lines, BMW, and Forbes. You see, businesses irrespective of their types are trying to look out for numerous ways to come up with a successful online presence and to be precise, Angular is one of those sure-shot ways since it allows you to deliver great user experience, easy access, high-end speed, efficiency and productivity and the list goes on with cutting-edge capabilities.
Further, let’s go through some benefits offered by the Angular framework that shouldn’t be avoided at any cost.
Benefits of Considering Angular Framework
#1 Out-of-the-box functionality
The first and foremost benefit of considering Angular is that it offers several out-of-the-box functionalities. Let’s say, for example, tools to take care of routing. With such a wide range of tools available, it is possible to fetch relevant data that you want to incorporate into the existing application. Now you must be well-known with the fact that Angular comprises of a preconfigured environment that not only offers assistance in conducting seamless development but testing as well.
In fact, to create basic functionality, developers no longer require to seek assistance from third-party libraries as the development framework offers it all. Check out its official library and I assure you that you are completely sorted.
#2 Best Cross-Platform Development
The next amazing benefit offered by the Angular framework is that it turns out to be the best bet for conducting cross-platform development. You see Angular offers great assistance in developing progressive web apps which tend to run across different mobile platforms. And this concept of cross-platform development is highly used in developing native-like mobile applications. There was a time when developers tend to use Ionic + Angular for such astounding results but this is certainly not the case anymore.
And since Angular comprises of different typescript capabilities such as services, dependency injection, and routing, receiving a native-like UI is definitely possible. Also here you will find a wide range of structural elements such as Injectors, Components, Directives, Pipes, and Services, each one definitely results in developing high-quality applications.
#3 Consistency
Another amazing benefit offered by the Angular framework turns out to be that this one is a fully-fledged responsive web design framework that turns out to be great, especially in creating a good amount of consistency. Basically, the ultimate objective here is to make sure that everything falls in place and that developers exactly know what needs to be done the moment they join the development project.
Great consistency brings great productivity, yes developers are no longer required to spend an insane amount of time in figuring out what a function does or a component does, once you have mastered these all, it becomes pretty easy to code. Not to mention, Angular is one such framework that comprises of high readability.
I can simply go on and on when it comes to benefits offered by the Angular framework such as detailed documentation, Angular CLI, Two-way binding, Google support, a Large developer community and the list goes on.
Moving on, time to focus on the best practices when you are conducting an Angular development project.
Top Angular Best Practices
#1 Angular Coding Styles
One of the common yet pretty popular Angular best practices to take into account is the use of Angular coding styles. You see when you end up gaining efficiency in coding, the overall effectiveness and efficiency of the app increases. You see in conducting an Angular development project, the overall code quality and code health plays a pretty significant role. So make sure to hire Angular developers in India who try to match pre-defined Angular coding standards and coding styles. When not done so, be ready to face unwanted difficulties, bugs, and issues because of complex code structures. So what to do?
-
- Ensure that the code does not exceed 400 lines limit per file
-
- For each function, the code lines must be limited to 75 lines
- If the variable has constant values, declare them right away
- Always leave an empty line between imports and modules
- Name of the properties and methods must be in the lowercase
- Naming the interfaces is not a good idea at all
#2 Clear Folder Structure
Another interesting Angular best practice to take into account is the folder structure.
This is what it looks like once you are done with creating some components. Technically speaking, the directories are created by the CLI, no two ways about it. However, what you can do is try developing some extra folders to group it and even more, you can make sure to use clear names. Further, I would like to share another image where you may find a more complicated-looking structure featuring a wide range of elements, which can be a huge mess in the later stages.
Some of the basic advantages of using a clear folder structure include:
- Easy recognition
- Great visibility regarding code dependencies
- Searching and grouping concrete files is easy
#3 Breaking large components into manageable sizes.
Another amazing Angular best practice to take into account is breaking the set of large components into a wide range if manageable sizes. As mentioned earlier, it is very important to keep the code files clean and crisp. The same habit should be considered when dealing with components as well. Sometimes components can turn out to be pretty tricky to test, debug and maintain. So when you break it down into smaller chunks or more manageable ones, this definitely results in high-end productivity and efficiency.
#4 Angular CLI
As mentioned earlier, Angular CLI is one of the most popular and best angular development practices that shouldn’t be ignored at any rate. So what is Angular CLI, it is a command-line interface tool that is used for conducting different tasks such as initializing, developing, scaffolding, maintaining, testing as well as debugging apps. Angular CLI is highly recommended for building initial-level structure and not just that, it becomes way more easier for developers to understand the overall app flow, and folder structure and saves a plethora of developer’s time.
-
- Ng new – Creating an app that works wonders
- Ng generate – Using to generate different components, services, routes and pipes with test shells.
- Ng Serve – Assists well in testing apps locally especially when developing
-
- Ng Test – Possible to run different angular tests
- Ng Lint – Makes the Angular code Shine
- Ng Add @angular/PWA – Lastly, sets up Angular service worker
#5 Using TypeScript strict mode
With the inception of all available latest versions of Angular, the use of Angular CLI and Typescript has become the default setting so there are times when the developers don’t even realize that they are using it. So what exactly is the strict mode, it is a set of rules that enforce a specific bunch of methods of writing code.
noImplicitAny, noImplicitThis, strictBindCallApply, strictNullChecks, strictFunctionTypes, strictPropertyInitialization and alwaysStrict. The good news is that most of them are self-explanatory. So whenever you want you can turn it off and on via the tsconfig.json file
Overall, you are bound to receive a better-crafted code as there are enforced rules present.
#6 Do not forget to save the memory bytes
One of the most astounding built-in attributes of Angular is Async Pipes. Now these ones have the potential to save you a boatload of memory bytes when you build a large-scale application frequented by thousands of users. The best thing here is that they come in handy and tend to limit unnecessary memory leakages.
@Component({
selector: ‘async-observable-pipe’,
template: ‘
observable|async: Time: {{ time | async }}
‘ })
export class AsyncObservablePipeComponent
{
time = new Observable((observer: Observer) => {
setInterval(() => observer.next(new Date().toString()), 1000);
});
})
Conclusion
So that’s all for now! The aforementioned are some of the best and most popular angular development practices to take into account. So next time you think of hiring Angular developers in India, make sure you are well aware that they are using at least a few of the aforementioned Angular development practices. I hope you did find the post exciting and informative. If so, do share among others and let us know if you find any relevant angular best practices being missed out.
