Why Relying on “@angular/core” and/or “rxjs” Could Be a Problem

If you’re a developer working with Angular, you’re likely familiar with the “@angular/core” and “rxjs” libraries. These libraries are commonly used in Angular applications for various functionalities. However, relying too heavily on these libraries can lead to problematic issues down the road.

One issue is that these libraries can quickly bloat your application. “@angular/core” contains a large set of modules, services, and components that you may not need for your specific application. Similarly, “rxjs” has a large number of operators and functions that can add unnecessary weight to your application.

Another issue is that these libraries are constantly changing. “@angular/core” updates frequently with new releases, and “rxjs” recently underwent a major version change. This can cause compatibility issues and break your application if you’re not careful to keep up with the latest changes.

Finally, relying too heavily on “@angular/core” and “rxjs” can make your code less modular and harder to maintain. If you’re depending on these libraries for many different functionalities, it can be difficult to keep track of what code relies on them and how they interact with each other.

While “@angular/core” and “rxjs” are powerful libraries that can enhance your Angular application, it’s important to be mindful of their drawbacks and limitations. By carefully considering which functionalities you truly need from these libraries and utilizing alternatives when possible, you can avoid potential issues down the road.

The Pros and Cons of Using Third-Party Libraries like “@angular/core” and/or “rxjs”

When working on a software project, developers often have to decide whether to use third-party libraries or to build their own code from scratch. In the case of front-end development, libraries like “@angular/core” and “rxjs” are often used to speed up development, but there are both pros and cons to using them.


  1. Saves Time: Using third-party libraries like “@angular/core” and “rxjs” can save developers lots of time and effort because they don’t have to write all the code from scratch.

  2. Improved functionality: Third-party libraries often provide useful functions that are not available out of the box. “@angular/core” and “rxjs” are no exceptions, and they provide a lot of functionality that can improve the performance and functionality of a web application.

  3. Community support: Popular open source libraries like “@angular/core” and “rxjs” have a large community of developers who contribute to their development and find or fix bugs, which means they are more reliable as compared to the code written from scratch.


  1. Learning curve: Third-party libraries like “@angular/core” and “rxjs” have a learning curve, developers initially have to spend some time learning how to use it effectively.

  2. Update compatibility: Libraries like “@angular/core” and “rxjs” are continuously updated with new functionalities and features, which means developers need to ensure that their code is compatible with the latest version of the library.

  3. Security and Bugs: There is always a risk when using an external library that there might be security vulnerabilities or bugs in the code.

In conclusion, using third-party libraries like “@angular/core” and “rxjs” has both advantages and disadvantages. It might be a good choice for developers to use them as long as they are aware of the risks and do thorough research before incorporating them into their projects.
