# SolidusGraphqlApi
[](https://codeclimate.com/github/solidusio/solidus_graphql_api/maintainability)
[](https://codeclimate.com/github/solidusio/solidus_graphql_api/test_coverage)
[](https://circleci.com/gh/solidusio/solidus_graphql_api)
[](https://badge.fury.io/rb/solidus_graphql_api)
Provides a [graphql](https://graphql.org/) api for the [Solidus](https://github.com/solidusio/solidus) ecommerce framework.
## Supported Versions
- Solidus 2.11.x
- Solidus 3.x
## Installation
Add solidus_graphql_api to your Gemfile:
```ruby
gem 'solidus_graphql_api'
```
Bundle your dependencies and run the installation generator:
```shell
bin/rails generate solidus_graphql_api:install
```
Unlike the REST API which has a variety of endpoints, the GraphQL API has a
single endpoint accessible under `/graphql`. It will be automatically
inserted into your `routes.rb` file after running the generator.
For example in development you can use:
```
POST http://localhost:3000/graphql
```
## Documentation
The Solidus GraphQL API documentation can be found [here](https://solidusio.github.io/solidus_graphql_api/docs/).
## Customizations
You can extend the gem functionality through decorators, just like Solidus.
For example, assuming we are placing our grapqhl decorators in `app/graphql/types`:
### Adding a new field
```ruby
module Graphql
module Types
module ProductDecorator
def self.prepended(base)
base.field :test, GraphQL::Types::String, null: true
end
def test
'test'
end
SolidusGraphqlApi::Types::Product.prepend self
end
end
end
```
or also, if we want to add the taxon relation to the type product:
```ruby
module Graphql
module Types
module ProductDecorator
def self.prepended(base)
base.field :taxons, SolidusGraphqlApi::Types::Taxon.connection_type, null: true
end
def taxons
SolidusGraphqlApi::BatchLoader.for(object, :taxons)
end
SolidusGraphqlApi::Types::Product.prepend self
end
end
end
```
### Modifying an existing field
Like for adding a new field, we modify the `name` field in the same way:
```ruby
module Graphql
module Types
module ProductDecorator
def self.prepended(base)
base.field :name, GraphQL::Types::String, null: true
end
def name
object.concat(' ', 'Graphql')
end
SolidusGraphqlApi::Types::Product.prepend self
end
end
end
```
### Removing a field
```ruby
module Graphql
module Types
module ProductDecorator
def self.prepended(base)
base.remove_field :name
end
SolidusGraphqlApi::Types::Product.prepend self
end
end
end
```
### Adding a new Type
Let's say we want the Product type to return its stock_items:
First we create a StockItem type:
```ruby
module Graphql
module Types
class StockItem < SolidusGraphqlApi::Types::Base::RelayNode
description 'StockItem.'
field :count_on_hand, Integer, null: false
end
end
end
```
And in the product decorator type:
```ruby
require_relative 'stock_item'
module Graphql
module Types
module ProductDecorator
def self.prepended(base)
base.field :stock_items, Graphql::Types::StockItem.connection_type, null: false
end
def stock_items
object.stock_items
end
SolidusGraphqlApi::Types::Product.prepend self
end
end
end
```
The query may look something like:
```ruby
query productBySlug ($slug: String!) {
productBySlug (slug: $slug) {
stockItems {
nodes {
countOnHand
}
}
}
}
```
### Adding a new Query
```ruby
module Graphql
module Types
module QueryDecorator
def self.prepended(base)
base.field :taxons, SolidusGraphqlApi::Types::Taxon.connection_type, null: false
end
def taxons
Spree::Taxon.all
end
SolidusGraphqlApi::Types::Query.prepend self
end
end
end
```
In your application you probably want to create a query object to retrieves the taxons.
Check `SolidusGraphqlApi::Types::Query` for examples.
## Development
### Testing the extension
First bundle your dependencies, then run `bin/rake`. `bin/rake` will default to building the dummy
app if it does not exist, then it will run specs. The dummy app can be regenerated by using
`bin/rake extension:test_app`.
```shell
bundle
bin/rake
```
To run [Rubocop](https://github.com/bbatsov/rubocop) static code analysis run
```shell
bundle exec rubocop
```
When testing your application's integration with this extension you may use its factories.
Simply add this require statement to your spec_helper:
```ruby
require 'solidus_graphql_api/factories'
```
## Running the sandbox
To run this extension in a sandboxed Solidus application, you can run `bin/sandbox`. The path for
the sandbox app is `./sandbox` and `bin/rails` will forward any Rails commands to
`sandbox/bin/rails`.
Here's an example:
```shell
$ bin/rails server
=> Booting Puma
=> Rails 6.0.2.1 application starting in development
* Listening on tcp://127.0.0.1:3000
Use Ctrl-C to stop
```
### Updating the changelog
Before and after releases the changelog should be updated to reflect the up-to-date status of
the project:
```shell
bin/rake changelog
git add CHANGELOG.md
git commit -m "Update the changelog"
```
### Releasing new versions
Please refer to the dedicated [page](https://github.com/solidusio/solidus/wiki/How-to-release-extensions) on Solidus wiki.
