What An Angular Developer Should Know In 2023? (Checks, Tips & Tests)
Angular has come a long way since AngularJS. (as if you didn't already know that) If you’ve been searching forums and reading blogs to know what an Angular developer should know, this is where you stop.
As an executive/decision-maker looking to hire Angular resources for your projects, you may have often wondered about how Angular works. Moreover, you must have scratched your head about what to look for when hiring developers in Angular.
In this article, we'll provide you with a one-stop guide to understanding Angular and what an Angular developer should know.
So, What's Angular?
If you didn’t already know, Angular is a front-end web application framework, used to build single-page applications and everything in between(if you know how). It's a powerful tool for creating dynamic and responsive user interfaces, making it a popular choice for web developers around the world.
The Essential Skills You Should Look For When Hiring Any Angular Developer
To work with Angular, your developers should have a solid understanding of web development fundamentals such as HTML and CSS. They also need to be familiar with TypeScript, a superset of JavaScript that is used for building Angular applications. JavaScript is also an important skill for Angular developers to have, as it's the backbone of many web applications.
As we mentioned already Angular is a web application framework that uses a component-based architecture. Wondering what that is?

So, in essence, this means that developers can create individual components that can be reused across different parts of their applications. Angular also uses modules to organize code and services to help manage data across components.
Overall, understanding Angular fundamentals such as TypeScript, JavaScript, HTML, and CSS is essential for any Angular developer. By having a strong foundation in these areas, developers can create powerful and effective single-page applications using the Angular web application framework.
What An Angular Developer Should Absolutely Know? (Non-Negotiable)
When it comes to hiring an Angular developer, there are certain essential skills you should look for. Here are some of the key skills that any talented Angular developer should possess:
Angular development skills
This is a no-brainer, but any Angular developer you hire should have experience working with the Angular web application framework. Look for candidates who have built complex and dynamic web applications using Angular.
- Understanding of TypeScript and its usage in Angular
- Knowledge of Angular's core features and capabilities
- Experience with Angular CLI and other development tools
- Knowledge of Angular's architecture and its best practices
- Experience in creating and implementing custom directives, pipes, and services
Front-end development skills
While Angular is a front-end web application framework, it's important to find developers who have a strong understanding of front-end development in general. This includes experience with HTML, CSS, and JavaScript, as well as the ability to create responsive and user-friendly interfaces.
- Proficiency in HTML, CSS, and JavaScript
- Experience in creating responsive and user-friendly interfaces
- Understanding of web accessibility and its importance
- Knowledge of CSS frameworks such as Bootstrap, Material UI or TailwindCSS
- Experience in optimizing web applications for performance
Web application framework skills
In addition to Angular, it's also important to find developers who have experience working with other web application frameworks. This can include frameworks like React, Vue.js, and Ember.js.
- Understanding of different web application frameworks such as React, Vue.js, and Ember.js
- Knowledge of the differences and similarities between web application frameworks
- Experience in creating web applications using other web application frameworks
Components architecture in Angular
As mentioned earlier, Angular uses a component-based architecture to help developers create reusable components for their web applications. Look for candidates who have experience designing and implementing components in Angular.
- Knowledge of component architecture concepts and design patterns
- Experience in designing and implementing reusable components
- Familiarity with different lifecycle hooks of an Angular component
- Understanding of the importance of separation of concerns in Angular
Modules in Angular development
Modules are used in Angular to organize code and create separation of concerns in web applications. Look for candidates who have experience working with modules and understand how to structure code in a modular way.
- Knowledge of modules in Angular and their purpose
- Experience in structuring code in a modular way
- Familiarity with shared modules and lazy-loaded modules
- Understanding of module hierarchy and dependency injection in Angular
Services in Angular development:
Services are used in Angular to manage data and provide functionality to components. Look for candidates who have experience working with services and understand how to create and use them effectively in Angular applications.
- Knowledge of services in Angular and their purpose
- Experience in creating and using services in Angular
- Familiarity with different types of services in Angular
- Understanding of dependency injection and how it works in Angular
By finding developers who possess these essential skills, you can ensure that your Angular web application development project is in good hands.
Best Practices That Any Skilled Angular Developers Should Possess
When hiring an Angular developer, it's important to look for someone who not only has the necessary technical skills but also follows the best practices in Angular development. Here are some best practices that any skilled Angular developer should possess:
Follow the Angular Style Guide:
The Angular team has created a comprehensive style guide that covers various aspects of Angular development, including naming conventions, file structure, and coding practices. Any skilled Angular developer should be familiar with and follow this style guide to ensure consistency and maintainability of the codebase.
Use Reactive Programming:
Angular provides RxJS, a reactive programming library, which enables developers to create more responsive and scalable applications. Skilled Angular developers should know how to leverage RxJS to handle complex application scenarios, such as handling asynchronous operations and managing state.
Keep Components Small and Focused:
Components are a core part of Angular development, and skilled developers should know how to create small and focused components that perform a specific task. This helps to keep the codebase maintainable and reusable.
Tools & Resources To Test On
When hiring an Angular developer, it's important to assess their proficiency in using various tools and resources for Angular development. Here are some tools and resources that any skilled Angular developer should know and have experience with:
RxJS Library:
As mentioned earlier, RxJS is a reactive programming library that enables developers to create more responsive and scalable applications. Skilled Angular developers should be proficient in using RxJS and its various operators, such as map, filter, and debounce.
NgRx Library:
NgRx is a state management library for Angular applications that uses the Redux pattern. Skilled Angular developers should be familiar with NgRx and know how to use it to manage the state of their applications.
Redux Library:
Redux is a popular state management library for web applications, and skilled Angular developers should be proficient in using it to manage the state of their applications. Even though NgRx is the preferred state management library for Angular applications, knowledge of Redux is still valuable.
