Angular for Web App Development: Best Practices to Keep in Mind in 2023

by Tech Addict Writer, Blogger

Among the most celebrated JavaScript frameworks in the market, Angular has much more to its credit than the tag of being a Google offering. They are used for building single-page apps, web apps & native apps. Angular’s popularity continues to surge worldwide.

Angular, developed by Google, is now a typescript language - as a rewrite of AngularJS. It is the most powerful framework for building dynamic programming structures. The main building blocks for Angular include; modules, components, metadata, templates, data binding and more. It uses Typescript, a superscript of the JavaScript framework for developing Angular applications.

If you plan to build an app using this nifty framework, let us share some best practices to help you get optimal results from the development project.

Ensure the components are small: One of the most persistently-shared best practices for working with Angular is that members are better when they are small. More significant elements can be challenging to maintain, test, and debug. Hence, it is a good idea to break down more extensive components into smaller ones for developers’ efficiency.
Reusable components are suitable: Before developing an app, think about the UI and where the UI will be used. If the UI needs to be used in several places across the app, it is imperative to build the UI with reusable components. It will save developers the cumbersome task of making extensive changes across the entire code if significant UI changes are necessary. With reusable components, one will need not make the requisite changes in all the places in which the UI has been used; instead, they will be able to change the code in the component and be done with it.
Do not forget to let go of subscriptions: Among the biggest and most common mistakes programmers, especially novices, make is failing to unsubscribe from a stream after using it. Unsubscribing is the ngOnDestroy() method that allows programmers to prevent performance issues and memory leaks. And do not worry if you are using several subscriptions in the app —use the Subsink library to make the management of these subscriptions easier.
Decide if methods will be public or private: Another good practice to remember is figuring out which methods or variables will be designated public or private. Why? Well, because not all of them ought to be accessible from outside the class, so encapsulate the courses in a manner that ensures only specific fields are exposed outside the class. This practice helps prevent users from accidentally changing areas in categories that should be ideally left alone. Furthermore, this practice also hides the use of courses from the user and minimizes the scope of human error.
Lazy loading: Lazy loading refers to the concept of loading precisely the thing the developers are working on. So, say one is working on a particular feature; lazy loading ensures only the components and files relevant to the feature in question are loaded instead of loading everything all at once. In Angular, lazy loading usually loads different modules such as images, videos, documents, CSS, JS, etc. and helps boost the pace at which the app can load. The lazy loading feature ensures this acceleration in rate by organizing the app across various packets and then packing them only when requested. It is an absolute must to include this provision in your Angular app to ensure consistent and quick performance.
Keep an eye on the folder structure: Decidedly among the most common and most straightforward Angular best practices is maintaining a full file and folder structure to ensure the coding process is much easier. In the context of files, make sure that the file names follow a consistent pattern, i.e. the file’s feature is mentioned first, followed by the type. You can use a period to separate the component and style if you so wish. You must also pay close attention to the folder structure and class naming. For classes, ensure the correct use of the upper camel case style with the suffix alluding to the file type.

There you have it, ladies and gentlemen: some of the essential best practices you should keep in mind when developing a product with Angular. Angular is, no doubt, among the leading web development framework in the world to use for creating highly dynamic and robust UI apps. It is, after all, a Google offering, so there is already plenty of trust in this tool. However, if you want to optimize the value of what Angular can do for your project, then you ought to keep the aforementioned best practices in mind. It means paying close attention to components, ensuring reusable components, making sure that you use a proper structuring method for the folders, etc. In addition, it would also help to adhere to Angular coding standards and use interfaces. While all of these tips will come in handy for Angular app development, you could also engage the services of a trusted service provider for such a development project. But before you sign the dotted line, make sure to verify their credentials and expertise.
