Introduction

This is a simple i18next backend to be used in the browser. It will load resources from a firebase database using firebase.

Getting started

Source can be loaded via npm, bower or downloaded from this repo.

# npm package
$ npm install i18next-firebase-backend

# bower
$ bower install i18next-firebase-backend

Wiring up:

import i18next from 'i18next';
import XHR from 'i18next-firebase-backend';

i18next
  .use(XHR)
  .init(i18nextOptions);

• As with all modules you can either pass the constructor function (class) to the i18next.use or a concrete instance.
• If you don't use a module loader it will be added to window.i18nextFirebaseBackend

Backend Options

{
  // path where resources get loaded from, or a function
  // returning a path:
  // function(lngs, namespaces) { return customPath; }
  // the returned path will interpolate lng, ns if provided like giving a static path
  loadPath: '/locales/{{lng}}/{{ns}}',

  // path to post missing resources
  addPath: 'locales/add/{{lng}}/{{ns}}',

  // allow cross domain requests
  crossDomain: false,

  // define a custom xhr function
  // can be used to support XDomainRequest in IE 8 and 9
  ajax: function (url, options, callback, data) {}
}

Options can be passed in:

preferred - by setting options.backend in i18next.init:

import i18next from 'i18next';
import XHR from 'i18next-firebase-backend';

i18next
  .use(XHR)
  .init({
    backend: options
  });

on construction:

  import XHR from 'i18next-firebase-backend';
  const xhr = new XHR(null, options);

via calling init:

  import XHR from 'i18next-firebase-backend';
  const xhr = new XHR();
  xhr.init(options);
