`open_api` provides PORO and serializers for OpenAPI and it supports OpenAPI v3.0.1.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'open_api'
```

And then execute:

$ bundle

Or install it yourself as:

$ gem install open_api

## Usage
It has two use case:

1. Serializing from PORO to yaml
2. Deserializing yaml to PORO

### Serializing

```rb
spec = OpenApi::Specification.new(
openapi: "3.0.1",
info: OpenApi::Info.new(
title: "Awesome API",
description: "It provides something awesome",
version: "1.0.0",
),
paths: OpenApi::Paths.new(
"/pets": OpenApi::PathItem.new(
get: OpenApi::Operation.new(
description: "Returns all pets from the system that the user has access to",
responses: OpenApi::Responses.new(
"200": OpenApi::Response.new(
description: "A list of pets.",
content: {
"application/json": OpenApi::MediaType.new(
schema: OpenApi::Schema.new(
type: "array",
items: OpenApi::Reference.new(ref: "#/components/schemas/pet"),
)
)
}
)
)
)
)
)
)

yaml = OpenApi::Serializers::YamlSerializer.serialize(spec)
File.write("spec.yml", yaml)
```

### Deserializing

```rb
yaml = File.read("spec.yml")
spec = OpenApi::Serializers::YamlSerializer.deserialize(yaml)
```

## 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, run `bundle exec rake bump:patch` to update the version, 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).
