# Layered Design for Ruby on Rails Applications
Layered Design for Ruby on Rails Applications, published by Packt
This is the code repository for [Layered Design for Ruby on Rails Applications](https://www.packtpub.com/product/layered-design-for-ruby-on-rails-applications/9781801813785), published by Packt.
**Discover practical design patterns for maintainable web applications.**
## What is this book about?
Ruby on Rails is an open-source framework for building web applications from scratch and develop a full-featured product. This book helps you keep the code maintainable while working on a Rails application by demonstrating the useful design patterns and exploring the common code abstractions.
This book covers the following exciting features:
* Discover Rails' core components and its request/response cycle
* Understand Rails' convention-over-configuration principle and its impact on development
* Explore patterns for flexibility, extensibility, and testability in Rails
* Identify and address Rails’ anti-patterns for cleaner code
* Implement design patterns for handling bloated models and messy views
* Expand from mailers to multi-channel notification deliveries
* Explore different authorization models and layers
* Use a class-based approach to configuration in Rails

## Instructions and navigations
All of the code is organized into folders. For example, Chapter02.
The `lib/` folder contains utilities to run code snippets. Most chapter folders also contain the `prelude.rb` file
with the environment configuration for the examples (dependecies, Rails application configuration, database schema extensions, etc).
You can run any example using the `ruby` command, for example:
```sh
$ ruby Chapter01/01-request-gc-stats.rb
Total allocations: 18573
```
### Using examples runner
You can also run examples using a specific runner scripts, which prints the source code along with intermediate
return values in addition to executing the code:
```sh
ruby run.rb Chapter01/01-request-gc-stats.rb
```
Here is an example output of the runner:
### Running Rails tasks
You can run Rails (Rake) tasks using the `bin/rails` executable:
```sh
$ bin/rails middleware
use ActionDispatch::HostAuthorization
use Rack::Sendfile
...
use Rack::TempfileReaper
run App.routes
```
You can also load the application modification for a particular chapter by specifying the `CHAPTER` env var:
```sh
$ CHAPTER=2 bin/rails routes
...
books GET /books(.:format)
books#index
categories GET /categories(:format)
categories#index
category GET /categories:id(.:format)
categories#show
```
Finally, you can run a Rails server for a particular chapter (some chapters contain controllers and views examples). For example, for Chapter 7:
```sh
$ CHAPTER=7 bin/rails rails s
[2023-01-30 22:45:37] INFO WEBrick 1.8.1
[2023-01-30 22:45:37] INFO ruby 3.2.0 (2022-12-25) [aarch64-linux]
[2023-01-30 22:45:37] INFO WEBrick::HTTPServer#start: pid=1266 port=3000
...
```
Now you can open a web server at [localhost:3000/users](http://localhost:3000/users) and play with the auto-generated Rails CRUD interface for users.
