Provides a collection named i18n, publication named i18n and a helper named i18n as well. Also provides a ji18n javascript function and a i18n_map function.

in client:

Session.set 'i18n.language', 'en'  # you can use whatever name you want
Session.set 'total_apples', 0

in iron-router:

class @HomeController extends RouteController
    waitOn: -> Meteor.subscribe "i18n", Session.get('i18n.language')
    data: ->
        total_apples: Session.get "total_apples"

in flow-router you can use the url:

http://localhost:3000/admin-post/?lang=es

and:

FlowRouter.route '/admin-post/',
subscriptions: (params, queryParams) ->
    lang = queryParams.lang or 'en'
    this.register('i18n', Meteor.subscribe("i18n", lang))

in html template:

<template name='home'>
<h1>{{total_apples}}: {{ i18n 'THERE_ARE_APPLES' count=total_apples }}</h1>
</template>

An example of a document of i18n collection:

{
    "language" : "en",
    "tag" : "THERE_ARE_APPLES",
    "count" : "2..",
    "value" : "There are {{count}} apples."
}

"2.." means that this translation will be used to values greater or equal to 2.

other example:

{
    "language" : "en",
    "tag" : "THERE_ARE_APPLES",
    "count" : "0",
    "value" : "There are no apples."
}

In value you can have more complex strings like:

"There are {{count}} {{fruit}} in the basket."

And use like:

{{ i18n 'THERE_ARE_FRUITS' count=total_fruits fruit=fruit }}

where fruit is passed here from the data section of iron-router.

ji18n is used this way:

text = ji18n('THERE_ARE_APPLES', {count:0})

And here is an example on how to map languages:

map =
  es:
    SAVE:
      any: 'Guardar'
  en:
    SAVE:
      any: 'Save'

i18n_map(map)
