Welcome to Yata integration Hex package, this package will allow you to easy get your translations from service.


Add yatapp to your list of dependencies and to applications in mix.exs:

# mix.exs

def deps do
    {:yatapp, "~> 0.2.4"}

def application do
  [applications: [:yatapp]]


Package can be used in two ways:

  • integration through API
  • websocket integration

API Integration

Add configuration to your config/config.exs:

# config.exs

config :yatapp,
  api_key: System.get_env("YATA_API_KEY"),
  project_id: System.get_env("YATA_PROJECT_ID"),
  locales: ~w(en),
  translations_format: "yml",
  save_to_path: "priv/locales/",
  root: false,
  strip_empty: false,
  enable_websocket: false

API integration allows you to download all translation using mix task:

$ mix yatapp.download_translations

Websocket Integration

Add configuration to your config/config.exs:

# config.exs

config :yatapp,
  api_key: System.get_env("YATA_API_KEY"),
  project_id: System.get_env("YATA_PROJECT_ID"),
  default_locale: "en",
  locales: ~w(en),
  otp_app: :my_app,
  json_parser: Jason,
  store: Yatapp.Store.ETS,
  download_on_start: false,
  save_to_path: "priv/locales/",
  translations_format: "json",
  translation_file_parser: Jason,
  root: false,
  strip_empty: false,
  enable_websocket: true,
  var_prefix: "%{",
  var_suffix: "}",
  fallback: false

Websocket integration connects to Yata server and stays open. All changes in translations are auto-fetched to the app.

When app connects to the Yata server for the first time it fetches all translation and saves them to the ets table. Then all actions on translations like create, update and delete are broadcasting information and ets table is updated.

The values for given locale and key can be fetched using Yatappp.ExI18n module:

# Examples

# en
number: 1
hello_name: "Hello %{name}"

Yatapp.translate("en", "number") #=> 1
Yatapp.translate("en", "hello_name", %{name: "John"}) #=> "Hello John"


Yata Pluralization is useful when you want your application to customize pluralization rules. The base pluralizer is Yatapp.Pluralization.Base which apply rules with three keys: :zero, :one and :other. You can create your own and set it as your default pluralizer (see Yatapp.Pluralization.Example). To set new pluralizer change configuration settings:

# config.exs

config :yatapp,
  pluralizer: Yatapp.Pluralization.Example

The interpolation value :count has a special role it both is interpolated to the translation and used to pick a pluralization form the translations according to the pluralization rules defined in the pluralization backend.

# Examples

# en

  zero: "no message"
  one: "1 message"
  other: "%{count} messages"

Yatapp.translate("en", "messages", %{count: 0}) #=> "no message"
Yatapp.translate("en", "messages", %{count: 1}) #=> "1 message"
Yatapp.translate("en", "messages", %{count: 2}) #=> "no messages"

Language Plural Rules (CLDR)
