Angular Best Practices: A Pathway to Create Scalable Apps

A

There is a widespread need among the developer community to build an app that is easy to maintain and scale. But somehow, they face challenges in doing so. That is why it is imperative to develop and deliver scalable apps. With an intent to help our Angular developers community globally, we are here with tried-and-tested angular best practices.

From hundreds of Best Angular practices, we have filtered out and shared some of the best of it so that you can optimise the app development process for scalability and low maintenance. These guidelines will ensure that your project’s code follows proper standards and is error-free. Here it goes:

Command Line Interface (CLI)

Angular CLI is a command-line interface (CLI) that generates the structure of your app. This structure helps to understand the flow of the app and its components.

Additionally, it is a tool to initialize, develop, debug, and maintain your app’s code efficiently. The primary purpose of this tool is to prevent the jamming of JavaScript, and with CLI, project code management becomes easy. You can create new files with just a single code. Here is the command to install CLI:

Install Angular CLI

npm install -g @angular/cli

Check Angular CLI version

ng version

Break the components

Breaking up your components into small, easily maintainable pieces is another essential best practice for Angular developers. This method eliminates the need for the angular framework to detect significant components, which can be a challenge to debug and maintain.

Always consider the size of your modules when developing your apps. Besides, you can reuse small components wherever you wish. This Angular best practice reduces the code’s need, further fast-tracking the app development process.

Lazy Loading for Lazy Applications

In Angular, lazy loading is a great way to speed up your app, especially when the application is bulky. Using lazy loading, you can divide your application into bundles and load the components only when needed. This Angular best practice can load the video, images, documents, and CSS.

The main advantage of lazy-loading is that it prevents the application from becoming bloated. While this approach is not applicable angular applications, it will help speed-up loading the app and save time.

const routes: Routes = [

{

path: ‘profile’,

loadChildren: () => import(‘./modules/profile/profile.module’).then(m => m.ProfileModule)

}

];

 

Abstain from Creating Large Components

The first best practice is to avoid creating significant components. These can make the application harder to maintain and are difficult to debug. The best solution to this problem is building smaller components and managing them with separate files.

When it comes to coding, document the roles of variables and methods; this will help others read your code and minimise code duplication.

Adhere to Component-based Structure

An Angular developer strives to develop applications that are easy to maintain. An excellent way to do this is by making it a component-based architecture. Using a centralised state management system will help you avoid a lot of trouble in the future. Central state management will ensure that all of your components are easily accessible and maintained with a single code base. You can make your angular application better and faster by following this practice.

Stick to a centralised state management system

Use a centralised state management system. This will help you manage the state of your application and make it easy to communicate among components. It also solves the problem of communication between members.

This technique is beneficial in scalable building applications. It can be used for high-quality performance and helps your application to scale. Its application will help you to make the project more secure and maintainable.

Some benefits of using a centralised state management system:

  • Easy to troubleshoot the application
  • Code will be clutter-free
  • Centralised control on state transition
  • Third-party tools are available for detecting and debugging in state management libraries.

Create Single Class Components

One of the most essential Tried and Tested Angular best practices is to create components with only a single class. This is because smart features handle API calls, and dumb components focus on appearance.

In contrast, a single component can contain several subcomponents, including a UI component, an application, and a database. If you want to write a component with a lot of functionality, it’s better to write a component with a single class instead of a complex hierarchy.

Follow Coding Standards

While building applications in Angular, you should focus on following the coding standards. The coding standards of Angular are important because they will help your app run fast. A slow app can force users to close the application. By following the coding standards in a module, you can avoid these issues.

Avoid Redundancy

Don’t create multiple copies of a component or service in the same file. Creating multiple instances of a component or service is not efficient to build a complex application. Angular should be structured in a way that makes it easy to read. In a multi-page application, each file should only contain a single function.

Implement a Lucid Folder Structure

The folder structure is an extremely important factor for your app. Without a proper folder structure, your project will encounter several problems during its development. In addition, a poorly-structured project can be difficult to scale.

A folder structure should be such that it could incorporate modifications at scaling. And also, whatever the structure you follow, make sure it is uniform throughout the project; otherwise, it can create complications in code maintenance and debugging.

Check Errors While Coding

It’s important to avoid making changes to your code. It will affect the overall performance of your angular app. Moreover, they will affect the security of your application. Besides, you should follow all angular best practices to avoid errors.

It’s also important to follow Angular Strict Mode. This will automatically upgrade your angular application and prevent it from running into an error.

Make Proper Documentation

Building a full-fledged app is a team task. A whole team of programmers works on a project until the deployment. In order to help your teammate to understand the function of a module, make proper documentation. Make comments alongside the code to do so. It increases readability and makes code maintenance easy.

Wrap Up

So, these were the Angular best practices we recommend you to follow for smooth scaling and maintenance of your applications. We hope you will implement these angular best practices in your upcoming app development project.

You should hire a company with experienced angular developers who have experience using the framework. This will make the entire process simpler and faster. The goal is to build a website/app that people love.
