Angular Best Practices in 2022

Know The Angular Best Practices to Follow In 2023

Fact remains that as trends change, technologies have to adapt. In the software industry, all products or tools go through several upgrades each year to meet the changing needs of the sector. These upgrades are what enable tools to serve businesses of longer spans. When these tools evolve, the practices to leverage them have to change as well. As such, developers have to be consistently on the lookout for the latest news on tools that enable them to apply their skills in web and application development.

Today, we will discover some of the Angular module’s best practices in 2023. Before we dive into Angular best practices for performance, let’s take a quick look at what Angular is and what is its role in application development.

Two expert developers, Misko Hevery and Adam Abrons created AngularJS as a side project in 2009. It is a JavaScript-based, front-end web framework maintained by Google to resolve the complexities of developing single-page applications featuring smooth user interfaces. This framework uses HTML as a template language and lets you extend HTML syntax to best define an application’s components. Its data binding and dependency injection help eliminate a lot of the code that one would otherwise have to write.

Angular is now taking the lead amidst all the promising frameworks. One of the major reasons for its rising popularity is its modularity trait. This angular feature allows and enables web developers to create multiple modules easily for a single website application. It also recognizes the need to create an additional module so that it can be combined with other developed application modules.

Now that we have clarity on the importance of this structural framework, let’s explore some of the best practices in Angular.

Angular Best Practices 2023: Top 9

1. Adhere To Key Angular Coding Standards:

The very first rule to mastering any and every JavaScript framework is to get familiar with its coding style. After all, it is the quality of the code that gives applications their winning edge. Following certain coding standards can help developers easily identify errors and sail through the bug fixing process. Some coding standards are as good as mandatory. For example:

  • The code should also not exceed 75 lines for each function.
  • The code should not exceed the limit of 400 lines per file.
  • There should be an empty line between imports and modules.
  • Variables with constant values should be declared with ‘const.’

2. Leverage ng-bind In Place Of {{}}

Using ng-ding instead of {{}} works wonders. However, developers still face the dilemma of choosing between the double curly braces ({{}}) and ng-bind. There is a reason as to why the latter is the ideal choice – ng-bind is a directive that places a watcher on the passed variable. In addition, double curly braces are much slower in comparison as well.

3. Single Responsibility Principle:

Of all the coding practices in Angular, this one comes in handy every single time. It helps developers stay organized throughout the entire coding process. Developers have to ensure that every file is only associated with one specific purpose. This helps the codes to be readable and manageable, no matter how complex they get after being updated. It is important to not create more than one instance of any component, directive, or service within a single file.

4. Use Directive For DOM Handling:

AngularJS comes with a host of features that make it all the more functional – the directive being an important one. It is primarily designed for DOM Handling. Directives prove to be a blessing when a specific functionality or a reusable view component is required. Once developers have declared a directive for a particular view, they get to access it in any of the app sections.

5. Split Large Components Into Smaller Sizes:

The key to keeping a code clean and readable is to manage its little aspects; for example, the components. It is a taxing task to identify and fix bugs hidden in complex components. To avoid this, developers can break large complements into much smaller sizes that are easier to manage. They can be broken down to a point where each component features no more than one atomic task. This eventually helps increase the overall efficiency of the app as well.

6. Make Use Of Angular CLI:

Owing to its efficacy, leveraging Angular CLI is already a common practice among expert developers. Why is it important? This command-line interface tool does a great job when it comes to initializing, developing, maintaining, testing, debugging, and refining applications. Using Angular CLI to build an initial-level structure for the entire application makes it easier for the team to be on the same page in terms of the app flow and folder structure.

7. Controller As Syntax:

One of the best AngularJS practices is to conceal $scope and expose members from the controller to the view via an intermediary object. The controller enables developers to display only as much as they want at the moment. Developers can also use the controller to manipulate view data. Setting the data into the view through its controller is highly recommended.

8. Use Common HTTP Service:

For most developers out there, maintaining common services for API calls is a must. Error tracking and code optimization are two primary reasons for the popularity of this practice. Developers today prefer to maintain all the API calls through a single HTTP service instead of writing an HTTP service for each API call. This is one of the best ways of optimizing code.

9. Maintain Constant For All Constants:

Another great practice is to maintain a constant for the variables whose values are the same in the entire application. How does this help? During the development process, there are instances where the value of a particular variable has to be changed throughout the application. Maintaining constant for variables with similar values can make this happen. This way, when the value of that variable is declared, it will reflect throughout the application.
