Angular Development Best Practices

To begin with, Angular is always the first choice when it comes to building frontend applications for most web developers. Angular provides many promising and appreciable features to the entire web development process. But the question is that with so many businesses now adopting Angular, how can you stay on top of your game in development. And the answer is by following Top AngularJS best practices during your angular development approach.

Hands Down! Angular is one of the best programming javascript based frameworks out there. You can build programming structures like web apps, native apps as well as single-page applications. Particularly, Angular introduced as a Full Stack front-end-based JavaScript framework was sufficient yet highly flexible and convenient to build and integrate with other framework tools.  Angular gives you the guarantee to provide the best user experience possible for your users and customers. Let’s deep dive into the Angular development best practices that can bring clarity into your development approach:

Angular Coding Style

The most important perspective to get right for any front end JavaScript framework developer is to maintain and gain efficiency in coding.  Code health and coding quality play a highly important and significant role. This goes into deciding the efficiency and effectiveness for your app. Being a developer, you should always match your coding standards by practicing certain coding styles for Angular development. By doing this, developers can minimize the difficulty faced when dealing with complex code structures and identify immediate issues.

Best coding rules that comply with standard Angular Style Guide:

• It is best to ensure that your code does not exceed 400 lines per file that you maintain. You should always enforce yourself to use only 400 lines of code per file
•  The code written for each function should not exceed 75 lines per function.
• If any variable that you declare in your code, should have constant values then ensure you use Const and declare then using this keyword.
• Always ensure that the names of properties and methods should use Lower Camel case. eg iPhone, eBay, etc
• It is a known Angular development best practice to leave an empty line when using imports and modules.
• Best you avoid naming interface names using the capital Uppercase “I” as you would use in certain programming languages.

Principle of Single Responsibility

The most important practice that many angular professional developers follow including myself is to ensure that you don’t create more than one instance of anything. This instance for function, directive, service should be limited to one and only one per file. Each file should be best responsible for only a particular single function. Following this rule will ensure that your code is clean and readable as well as maintainable and easily understandable.  This rule helps in increasing the maintainability of your code.

Break Code Into Manageable Size

Particularly, Just as it is important for you to keep your code clean, it is important for you to maintain this practice of breaking code into manageable sizes. Ensure that you follow this habit for atomic components as well. Important components can often be difficult to maintain, tricky to test and debug. Moreover, your angular app will be greatly beneficial for other developers when you use the habit of breaking significant components into smaller more manageable ones. You should take note to understand that each component should only have one atomic task to perform.

Make Fruitful use of Angular CLI

# Install Angular CLI

npm install -g @angular/CLI

# Check CLI Version for Angular

ng version

Making efficient use of the Angular CLI or command-line interface is one of the Angular development best practices you cannot avoid. CLI is one of the most powerful tools available to programmers and developers is used for a multitude of different tasks by angular programmers. Command Line Interface is used heavily for maintaining, developing, testing, and debugging angular apps at the core level. You should always ensure that you make efficient use of angular CLI at the structure level for your application in its entirety. Particularly, making use of CLI enables developers to efficiently understand the flow and functionality of your application. As well, understanding the folder structure that saves a lot of developers time and effort.

Here are some essential CLI commands:

•  Create an app that works right out of the box (ng new)
•  Basically used for generation of components, routes, pipes, services in test shells (ng generate)
•  Used for testing your app locally during development (ng serve)
• Useful for shining your angular code (ng lint)
• Helps in setting and configuring the angular service worker (ng add @angular/PWA)

Efficient Utilization of Lazy Loading

Always ensure that you make use of lazy loading in your applications. Lazy loading is a feature that is built-in within Angular that ensures only visible components and code structures are loaded in the angular application. Lazy loading stops unnecessary components and structures from being loaded, thus delaying the process of loading that provides a feel of efficiency for your application. It also provides an illusion that your application is of high performance in nature.

Use trackBy along-with ngFOR

Always ensure that you use ngFOR. This allows developers to enable rerendering for the entire DOM tree after you finish making any changes to your array. This instructs Angular to make specific changes and render them only for the array. This also avoids rendering of the entire DOM tree that can put a load on your resources and take more time to execute.

Optimize Folder and File Structure for Angular

The most anticipated Angular development best practice is optimizing File and folder structure. It is pivotal and highly important for any angular developer to optimize their file and folder structure. Doing this allows for better readability, maintainability, efficiency as well as accessibility to your code. Developers at a single glance can make out what your code does and also provide valuable changes and suggestions to it. Maintainability is increased which helps fellow developers read colleagues’ code and suggest optimization for it. Always remember that consistency is highly important, especially when working with different partner members and teams.
