# OpenApiAnnotator [](https://badge.fury.io/rb/open_api_annotator) [](https://travis-ci.org/wantedly/open_api_annotator) [](https://codeclimate.com/github/wantedly/open_api_annotator/maintainability) [](https://codeclimate.com/github/wantedly/open_api_annotator/test_coverage)
OpenApiAnnotator realizes to generate OpenAPI spec by annotating to controllers and serializers.
If you use ActiveModelSerializer, this is the best way to generate OpenAPI spec.
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'open_api_annotator'
```
## Usage
Annotating controllers and serializers, you can generate OpenAPI spec file from these.
Things you have to do are three below:
1. Configure API meta information
1. Annotate controllers
1. Annotate serializers
### 1. Configure API meta information
You have to set API meta information like:
```rb
# config/initializers/open_api_annotator.rb
OpenApiAnnotator.configure do |config|
config.info = OpenApi::Info.new(title: "Book API", version: "1")
config.destination_path = Rails.root.join("api_spec.yml")
config.path_regexp = /\Aapi\/v1\// # If you want to restrict a path to create
end
```
### 2. Annotate controller
To define an entity of an endpoint, call the method `endpoint` in the previous line of an action method. It takes entity expression as the first arg. Entity expression is a model class or an array that contains only one model class.
```rb
class Api::V1::BooksController
endpoint [Book] # 👈It means an array of Book
def index
books = Book.limit(10)
render json: books
end
endpoint Book # 👈Just a Book
def show
book = Book.find(params[:id])
render json: book
end
endpoint Book # 👈Just a Book
def update
book = Book.find(params[:id])
book.update!(book_params)
render json: book
end
end
```
### 3. Annotate serializer
To define an schema in components, set `type`, `format`, `nullable` as each field option.
```rb
class BookSerializer < ApplicationSerializer
attribute :title, type: :string, nullable: false
attribute :published_at, type: :string, format: :"date-time", nullable: true
has_many :authors, type: [Author], nullable: false
has_one :cover_image, type: CoverImage, nullable: true
belongs_to :publisher, type: Publisher, nullable: false
end
```
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number using `bundle exec bump patch`(or minor, major), and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
