Powerful architecture that scales

Enterprise environment comes with its own set of challenges which are not present in the smaller organizations which can get away with an ad-hoc approach to development!

Standardized, repeatable and maintainable architecture is the key to success in an environment with multiple teams developing lots of applications.

This books delivers a complete toolkit for effortless Enterprise grade Angular Architecture

The implementation of automated architecture validation with ESLint is a transformative addition to the development workflow. It effectively resolves the challenge of upholding a clean and uniform architecture across the full span of the project’s life. Just configure it once, and you can rest easy!
Tomas's knack for clarifying concepts with extensive diagrams is outstanding. His method is not only instrumental in understanding the underlying principles but is also critical for any Angular developer looking to increase their accountability and ensure the successful delivery of their projects.

Automated Architecture Validation

Clean architecture is not only about the initial setup, but also about the ability to maintain it over time. Automated architecture validation is the key to ensure that your project stays maintainable and extendable over the whole project lifetime!

Without support of the automated tooling, we are basically left with the manual code reviews and the hope that everyone involved is paying 100% attention at all times which is just not realistic!

Tooling based architecture validation

  • Eslint based architecture validation with eslint-plugin-boundaries
  • Predefined set of proven architectural building blocks and rules to ensure that your project stays maintainable and extendable over time
  • In depth explanation of every architectural building block with lots of examples and approaches how to apply them to implement real world use cases
  • Explicitly defined relationships between architectural building blocks and list of common pitfalls to avoid
  • Powerful IDE integration to stay in the flow and catch the architectural violations as you type
  • Easy to integrate tooling to catch architectural violations in the CI/CD pipeline so no problematic code gets merged into the main branch

Tips & best practices

Lots of actionable tips and best practices based on the extensive experience, for example...

The boundaries/strict rule set is the way to go for all new projects, but it's also possible to start with the less strict boundaries/recommended rule set which is more suitable for existing projects as it allows us to have parts of the project non-compliant with the defined types, making it possible to refactor the codebase progressively.
When grouping logic in sub folders, always use domain based grouping, e.g. core/auth/ or core/user/ instead of grouping by building block type like core/services/ or core/reducers/ !
Both extreme approaches, loading files one by one (native module loading) and bundling all files into one huge bundle are suboptimal, and therefore the tooling helps us find balance with a smaller number of reasonably sized bundle files!
The issue with running the schematics from the terminal instead of the IDE is that in large projects, the paths can become very long and tedious or even downright hard to type correctly, which would predictably lead to the errors and frustration.

Ensuring success of Angular projects of any size


Having read lots of articles and books on Angular architecture this has been by far the best one yet!

It’s a great read from front to back and I was getting excited the further I got through the book and couldn't wait to start implementing the presented concepts and approaches in our projects!
The architecture gives a clear guidance on how to to structure your Angular applications and the automated architecture tests to ensure it continues to be followed are fantastic. Just a great book and architecture overall!

The book provides a deep dive into Angular CLI and development tools, emphasizing the power of Angular Schematics. It excellently differentiates between the eager and lazy parts of an Angular application, with the CoreModule playing a pivotal role. The author's approach of blending theory with practical examples makes complex concepts digestible.

The book provides invaluable assistance for those embarking on the journey of setting up a non-trivial Angular enterprise project. It strikes a perfect balance between being a hands-on and offering essential background information to explain key concepts. The step-by-step guide equips readers with the necessary tools to hit the ground running. A true gem lies in the detailed setup and explanation of automated architecture validation using ESlint.
