Introduction
This is a simple i18next backend to be used in the browser. It will load resources from a backend server using the xhr API.
Getting started
Source can be loaded via npm, bower or downloaded from this repo.
# npm package
$ npm install i18next-xhr-backend
# bower
$ bower install i18next-xhr-backend
Wiring up:
;; i18next;
- 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.i18nextXHRBackend
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}}.json' // path to post missing resources addPath: 'locales/add/{{lng}}/{{ns}}' // your backend server supports multiloading // /locales/resources.json?lng=de+en&ns=ns1+ns2 // Adapter is needed to enable MultiLoading https://github.com/i18next/i18next-multiload-backend-adapter // Returned JSON structure in this case is // { // lang : { // namespaceA: {}, // namespaceB: {}, // ...etc // } // } allowMultiLoading: false // set loadPath: '/locales/resources.json?lng={{lng}}&ns={{ns}}' to adapt to multiLoading // parse data after it has been fetched // in example use https://www.npmjs.com/package/json5 // here it removes the letter a from the json (bad idea) { return data; } //parse data before it has been sent by addPath { return key } // allow cross domain requests crossDomain: false // allow credentials on cross domain requests withCredentials: false // overrideMimeType sets request.overrideMimeType("application/json") overrideMimeType: false // custom request headers sets request.setRequestHeader(key, value) customHeaders: authorization: 'foo' // ... // define a custom xhr function // can be used to support XDomainRequest in IE 8 and 9 // // 'url' will be passed the value of 'loadPath' // 'options' will be this entire options object // 'callback' is a function that takes two parameters, 'data' and 'xhr'. // 'data' should be the key:value translation pairs for the // requested language and namespace, or null in case of an error. // 'xhr' should be a status object, e.g. { status: 200 } // 'data' will be a key:value object used when saving missing translations {} // adds parameters to resource URL. 'example.com' -> 'example.com?v=1.3.5' queryStringParams: v: '1.3.5'
Options can be passed in:
preferred - by setting options.backend in i18next.init:
;; i18next;
on construction:
;const xhr = null options;
via calling init:
;const xhr = ;xhr;
