Introduction

An i18next backend plugin to work with both local resources and remote backend. This plugin supports any other i18next backend. This backend will first load the local resources, and then will override them with the remote version.

Getting started

Installation via NPM:

$ npm install i18next-remote-backend-with-locals

Setup:

import i18next from 'i18next';
import Backend from 'i18next-remote-backend-with-locals';

i18next
  .use(Backend)
  .init(i18nextOptions)

As with all modules you can either pass the constructor function (class) to the i18next.use or a concrete instance.

Backend Options

{
  // An object that contains i18next resources. For example:
  localResources: {
    en: {
      hello: "Hello"
    },
    ja: {
      hello: "こんにちは"
    }
  },

  // Any kind of supported backend. See example with i18next-http-backend:
  remoteBackend: {
    type: i18NextHttpBackend,

    // Any options that the backend type accepts
    options: {
      loadPath: "http://example.com",
      parse: data => data,
      request: (options, url, payload, callback) => {
        axios.get(url)
          .then(res => callback(null, res))
          .catch(err => callback(err, null));
      },
    }
  }
}

Options can passed in:

Preffered - by setting 'backend' property on i18next.init:

import i18next from 'i18next';
import Backend from 'i18next-remote-backend-with-locals';

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

On construction:

import Backend from 'i18next-remote-backend-with-locals';

const Backend = new Backend(null, options);
const Backend = new Backend();
  Backend.init(null, options);

Via calling init:

import Backend from 'i18next-remote-backend-with-locals';

const Backend = new Backend();
Backend.init(null, options);

Complete Sample

import i18next from 'i18next';
import Backend from 'i18next-remote-backend-with-locals';
import i18NextHttpBackend from 'i18next-http-backend';
import en from './en.json';
import ja from './ja.json';
import id from './id.json';
import fr from './fr.json';

i18next
  .use(Backend)
  .init({
    fallbackLng: 'en',
    backend: {
      localResources: {
        en, 
        ja, 
        id, 
        fr,
      },
      remoteBackend: {
        type: i18nHttpLoader,
        options: {
          loadPath: 'http://example.com',
          parse: data => data,
          request: (options, url, payload, callback) => {
            axios.get(url)
              .then(res => callback(null, res))
              .catch(err => callback(err, null));
          },
        },
      },
    },
  });
