10 Angular Guidelines for Developers  

 Now that we have a better understanding of Angular’s standout features, let’s shift our focus to the best practices you can follow to craft robust and scalable applications with it: 

1. Rely on Angular Guidelines  

Starting from scratch, adhering to their Style Guide is crucial when it comes to keeping a consistent and clean codebase. The framework’s own coding style guide provides you with a manual covering naming conventions, coding standards, and file structure. This information is at your disposal, so feel free to make the most of it. 

2. Embrace CLI as Your Sidekick 

Angular uses the command-line interface (CLI) to abstract tooling complexity and optimize your code, allowing you to focus on building your app. Beyond its user-friendly interface, it enforces best practices, minimizes human error, and offers a standardized approach to project setup. This is why developers find it so valuable. 

3. Go for a Modular Approach  

 A brief disclaimer: Modularization is not strictly necessary for every case. In fact, Angular provides standalone components, which can be an excellent choice for specific projects.  

However, when it comes to developing large projects, modularity is still the recommended path to follow. This approach helps organize code, promotes reusability, and makes it easier to manage complex systems. By adhering to this best practice, you ensure you’ll achieve a well-organized, maintainable, and performant app. 

4. Dive into Reactive Forms  

Reactive forms ensure a structured, maintainable, and flexible approach to user input, resulting in more robust and scalable applications. They offer a strong validation and error-handling system, easing the creation of complex user interfaces. In addition, explicit control and separation of concerns improve testability, enabling reliable unit testing.  

5. Say No to Complex if/else Structures  

Minimizing if/else structures is a must if you’re aiming to write cleaner, more maintainable code. By reducing the complexity of conditional logic, your code becomes more readable and easier to maintain, fostering a streamlined development process.  

To steer clear of using if/else structures, you can take advantage of Angular’s specific features, including the ngSwitch directive, pipes, and custom directives. 

6. Optimize with Lazy Loading  

For large apps with lots of routes, think about employing lazy loading to load modules as needed. Instead of loading everything upfront, this mechanism helps keep smaller initial bundle sizes, reducing the amount of code users need to download.  

This not only results in quicker load times but also contributes to an overall improved user experience. To delve deeper into this topic, here’s a step-by-step guide on how to use this feature.  

7. Fine-Tune Change Detection  

Angular’s change detection monitors data and state changes, automatically updating the user interface to synchronize with the underlying data. 

While change detection is optimized for performance, excessive or unnecessary executions can lead to slowdowns. So, it’s essential to follow best practices and fine-tune the change detection process when building applications.  To learn how to use it carefully, here are some guidelines. 

8. Craft Unit Tests with Care 

Ensure code quality and maintainability by writing unit tests for your components, services, and other constructs, making sure that they work as expected and meet requirements. These can detect bugs early in the development process, ensuring that code changes don’t break existing functionality and making the system more maintainable and scalable.  

For writing and running unit tests, you can rely on Angular’s built-in testing framework, which uses tools such as Jasmine and Karma.  

9. Keep an Eye on Security  

Angular best practices also involve prioritizing security. Handling sensitive data and executing crucial operations in applications requires care to prevent vulnerabilities like data breaches, unauthorized access, and potential compromise of the entire app. Adhering to secure coding practices, regularly updating dependencies, and staying informed about the latest security trends are key components of a comprehensive security strategy.  

Additionally, ensure the trustworthiness of your applications by relying on the framework’s built-in protections against common threats. For instance, you can rely on content sanitization to keep your applications secure, and your users protected. This feature enhances security, keeping untrusted values for HTML, styles, and URLs clean and safe. This way, it prevents malicious or unsafe content from being executed or displayed in the app and serves as a shield against Cross-Site Scripting (XSS) attacks.  

10. Always Stay Up-to-Date 

While it may be self-evident, ensuring the ongoing updates of this technology allows you to leverage cutting-edge features, optimizations, and bug fixes.  

Staying in the loop with Angular tools and releases, learning about new features and changes, checking your application’s version, and updating your environment and apps are some of the ways you can get the most out of it. To simplify updates, the interactive Update Guide supplies customized instructions based on the versions you specify.
