Dialect is a painless nodejs module to manage your translations.

Install

npm install dialect

Dealing with translations in nodejs

Philosphy

  • Scalable: The translations should be available to any number of machines.
  • Fast: Getting translations from memory.
  • Reliable: Translations should be always available on a central repository/database.
  • Flexible: You should be able to use your favorite storage solution.

Example

var dialect = require('dialect').dialect({current_locale: 'es', store: {mongodb: {}}});

// connects to the store
dialect.connect(function () {

  // syncs the memory dictionaries with the store
  dialect.sync({interval:3600}, function (err, foo) {
    d.get('Hello World!'); // => Hola mundo
  });
});

Options

  • current_locale: Current locale used on your application.
  • base_locale: Base locale. Serves as keys on the dictionaries.
  • locales: Which locales are available on your application.
  • store: Object containing the store and their options

Store options

  • mongodb
    • database: dialect
    • host: 127.0.0.1
    • port: 27017
    • collection: translations
    • username (optional)
    • password (optional)
  • sqlite
    • database: dialect.db
    • table: dialect

API

  • config (key, value): Exposes configuration values.
  • get (query): Gets a translation cached in memory.
  • set (query, translation, callback): Sets a translation on the store.
  • approve (approve?, query, callback): Approve or rejects a translation.
  • sync (locale, repeat, callback): Syncs all the approved translations of the store to the memory cache.
  • connect (callback): Connects to the database store.

Plurals

Provide an array with the singular and plural forms of the string, the last element must contain a count param that will determine which plural form to use.

dialect.config('current_locale': 'sl'); // slovenian

[1, 2, 3].forEach(function (i) {
  dialect.get(['Beer', 'Beers', {count: i}]);
});

+---------------+-------------+
| found         | not found   |
+---------------+-------------+
| Pivo          | Beer        |
| Pivi          | Beers       |
| Piva          | Beers       |
+---------------+-------------+

You have an examle using plural forms in examples/plurals.js

Contexts

A context is a param that allows you to give a special meaning on a string. It helps the translator and it may generate diferent translations depending on the context.

dialect.config('current_locale': 'es'); // spanish

['female', 'male'].forEach(function (gender) {
  dialect.get(['My friends', gender]);
});

+---------------+-------------+
| found         | not found   |
+---------------+-------------+
| Mis amigos    | My friends  |
| Mis amigas    | My friends  |
+---------------+-------------+

String interpolation

You can put any param you want on the translation strings surrounded by moustaches {}. Remember that count and context have a special meaning although they can also be used with interpolations.

[1, 2].forEach(function (count) {
  ['female', 'male'].forEach(function (gender) {
    dialect.get([
      'You have {count} friend called {name}',
      'You have {count} friends called {name}',
      {count: count, context: context, name: 'Anna'}
    ]);
  });
});

+---------------------------------------+-----------------------------------------+
| found                                 | not found                               |
+---------------------------------------+-----------------------------------------+
| Tienes 1 amiga que se llama Anna      | You have 1 friend called Anna           |
| Tienes 1 amigo que se llama Anna      | You have 1 friend called Anna           |
| Tienes 2 amigas que se llaman Anna    | You have 2 friends called Anna          |
| Tienes 2 amigos que se llaman Anna    | You have 2 friends called Anna          |
+---------------------------------------+-----------------------------------------+

Store translations

To store a new translation, use the method set.

dialect.set(
  {original: 'I love gazpacho', locale: 'es'},
  'Me encanta el gazpacho'
);

dialect-http

Do you need a nice environment for your translators?

dialect http is an amazing http server to manage your translations.

Test

Dialect is heavily tested using testosterone

Benchmarks

Dialect should not add an overhead to your application on getting translations. Please run/add benchmarks to ensure that this module performance rocks.
