Derby Locale User

A derby-locale strategy that selects the user's locale preferences.

Installation

$ npm install derby-locale-user --save

Usage

In your server file, add the middleware before derby-locale:

var localeUser = require('derby-locale-user');

expressApp
  // ...
  // ...
  .use(localeUser())
  .use(locale())

Options

key – The path to the user's locales property. Defaults to local.locales.

name – The name of the strategy. Defaults to user.

order – The order of the strategy. Blank by default.

path – The path to the locale object. Defaults to $locale.

Dynamically Update

Create a reference from the strategy to the user's locale preference in order for the locale to update dynamically:

app.get('/', function (page, model, params, next) {
  var strategy = model.at('$locale.strategies.user');
  var userId = ...
  var user = model.at('users.' + userId);

  user.subscribe(function (err) {
    if (err) return next(err);
    strategy.ref('locales', user.at('local.locales'));  
    // ...
  });
});
