Summary

### Challenges and solutions in building large Angular apps

In large Angular applications, developers face several significant challenges. One major issue is managing complexity. These apps have lots of components, services, and modules that all need to work together smoothly. Keeping everything organized and easy to understand can be tough, especially with a big team.

Another problem is build times. As the app grows, it can take longer and longer for changes to show up during development. This can slow down the development process and make it harder to stay productive.

Dependency management is another headache. This involves making sure all the different parts of the app work well together and play nicely with outside libraries. 

### Tool limitations

Even experienced teams can struggle with managing large Angular applications without using the right tools. Organizing numerous components, services, and modules becomes challenging without tools that aid in clarity and team collaboration. Utilizing appropriate tools is key for experienced teams to successfully navigate the complexities of large Angular projects.

### Fixing problems with NX

NX offers several benefits for managing large Angular applications. It helps reduce the time it takes to build projects and keeps code well-organized by managing dependencies and structuring code into reusable parts. This makes it easier to maintain and expand applications over time.

One of NX's strengths is its ability to speed up builds. It does this by remembering previous build results and doing multiple tasks at the same time. This saves developers time and lets them make changes quickly.

NX also comes with tools for testing and checking code quality. It works well with common testing tools and helps keep code clean and consistent. This catches mistakes early and ensures code stays high-quality.

Furthermore, NX makes it easy to work together on projects. It keeps all code and shared parts in one place, making it simpler to share code between different projects or teams. This improves teamwork, reduces problems with combining code, and makes development smoother overall.

Manage Large Angular Apps and Supercharge Development Workflows

Learn how to create and maintain Angular applications using NX. 
Designed for Angular developers, this course covers best practices, improving workflow, and migrating existing applications to NX. 
Discover how to configure tools like Cypress for end-to-end testing and Storybook for UI component development. 
By the end of this course, you will have the knowledge and experience to work comfortably with NX on a daily basis.

Next-Level Angular Apps with NX

Build a simple time tracker application using NX monorepo.

Create a real-life NX monorepo with three applications. The main goal of these applications is to display the schedule for conference rooms on screens mounted to the doors of the respective rooms.

Build an admin panel as one of the applications to manage the schedule data for the conference rooms.

Use NX graph feature to visualize application architecture.

In this lesson, we'll summarize what you have learned.

NX is a mature product that comes with both advantages and disadvantages, as is the case with any software.
It is essential to recognize that there is no perfect code or tool that only has advantages.
NX follows the monorepo approach,
which means that every application, library, and file is located within the same repository.
This approach allows centralized code management
and simplifies development and collaboration within a single codebase.
NX works well with Angular, which was supported from the beginning.

So, it's time to sum up. As you can see, NX is a major product that comes with

and disadvantages. As everything, there is no perfect code, no perfect solution

So we have to be aware about both pros and cons of each week. NX is using a

which means that every application, every library, every piece of code is in

This reduces a lot of context switching of your team. You don't need to switch

you don't need to switch ID configuration, everything is in the same place. In

we will go through installation process and I will show you how to install NX
