GraphQL Rails i18n
Ruby on Rails i18n integration plugin for graphql-ruby, inspired by graphql-i18n npm library.
Installation
Install from RubyGems by adding it to your Gemfile, then bundling.
# Gemfile
gem 'graphql-rails-i18n'$ bundle install
Getting Started
follow the ### Step comments below to setup your schema with locale directive
class ExampleSchema < GraphQL::Schema
### Step 1: Use new interpreter runtime from graphql-ruby
use GraphQL::Execution::Interpreter
### Step 2: Declare locale directive in your schema
directive GraphQL::Schema::Directive::Locale
GraphQL::Schema::Directive::Locale::LocaleEnum.class_eval do
### Step 3: Tell @locale directive which languages are supported.
### Language code names are automagically added into LocaleEnum and
### underscored using `underscore` method.
### For instance: `zh-Hant-HK` will be transformed into `zh_hant_hk`.
locale(codename: 'en', description: 'English')
locale(codename: 'zh-Hant-HK', description: 'Hong Kong Traditional Chinese')
end
# In your Query root object
class Query < GraphQL::Schema::Object
field :localized_hello, String, null: false
def localized_hello
### Step 4: Deliver actual content data based on selected language
### ** Code below is for demostration only, you may hook up some
### i18n gems like `globalize` to output localized content.
case I18n.locale
when :en then 'Hello'
when :'zh-Hant-HK' then '您好'
else 'Hello in default language'
end
end
end
query Query
endYou can start making queries with locale directive.
query {
### Step 5: Write your query with @locale directive.
### Remember language code names are transformed automatically to underscore format.
defaultString: localizedString
englishString: localizedString @locale(lang: en)
chineseString: localizedString @locale(lang: zh_hant_hk)
}will output
{
"defaultString": "Hello in default language",
"englishString": "Hello",
"chineseString": "您好"
}
