We are big fans of the awesome vue, vuex and vue-router libraries and were just looking for an easy to use internationalization plugin, employing as much of the "standard library" as possible.
The main difference to other internationalization plugins is the ease of use and support for locales directly with the application or later from the server.
- Vue ^2.0.0
- Vuex ^2.0.0
$ npm install vuex-i18n
The vuex-i18n plugin is intended to be used for applications that use vuex as store and require localized messages. Make sure that both vue and vuex have been loaded beforehand.
The plugin provides a vuex module to store the localization information and translations and a plugin to allow easy access from components.
The plugin does not make any assumption on how you want to load the localization information. It can be loaded on start in your application bundle or dynamically after when the user is switching to a different language.
A corresponding example can be found in the test directory.
// load vue and vuex instance
import Vue from 'vue';
import Vuex from 'vuex';
// load vuex i18n module
import vuexI18n from 'vuex-i18n';
// initialize the vuex store using the vuex module. note that you can change the
// name of the module if you wish
const store = new Vuex.Store({
modules: {
i18n: vuexI18n.store
}
});
// initialize the internationalization plugin on the vue instance. note that
// the store must be passed to the plugin. the plugin will then generate some
// helper functions for components (i.e. this.$i18n.set, this.$t) and on the vue
// instance (i.e. Vue.i18n.set).
Vue.use(vuexI18n.plugin, store);
// please note that you must specify the name of the vuex module if it is
// different from i18n. i.e. Vue.use(vuexI18n.plugin, store, 'myName')
// add some translations (could also be loaded from a separate file)
// note that it is possible to use placeholders. translations can also be
// structured as object trees and will automatically be flattened by the the
// plugin
const translationsEn = {
"content": "This is some {type} content"
};
// translations can be kept in separate files for each language
// i.e. resources/i18n/de.json.
const translationsDe = {
"My nice title": "Ein schöner Titel",
"content": "Dies ist ein toller Inhalt"
};
// add translations directly to the application
Vue.i18n.add('en', translationsEn);
Vue.i18n.add('de', translationsDe);
// set the start locale to use
Vue.i18n.set('en');
// create a new component (requires a div with id app as mount point)
// you can use the method $t to access translations. the value will be returned
// as is, if no corresponding key is found in the translations
var app = new Vue({
store,
el: '#app',
template: `
<div>
<h1>{{ 'My nice title' | translate }}</h1>
<p>{{ $t('content', {'type': 'nice'}) }}
</div>
`
});The plugin provides easy access to localized information through the use of
the $t() method or the translate filter.
The plugin will try to find the given string as key in the translations of the currently defined locale and return the respective translation. If the string is not found, it will return as is. This allows to setup an application very quickly without having to first define all strings in a separate template.
<div>
// will return: "Some localized information"
{{ $t('Some localized information')}}
</div>The $t() method also allows for inclusion of dynamic parameters that can be
passed to the method in the form of key/value pairs
<div>
// will return: "You have 5 new messages"
{{ $t('You have {number} new messages', {number: 5}) }}
</div>There are also several methods available on the property this.$i18n or Vue.i18n
$i18n.locale(), Vue.i18n.locale()
// get the current locale
$i18n.set(locale), Vue.i18n.set(locale)
// set the current locale (i.e. 'de', 'en')
$i18n.add(locale, translations), Vue.i18n.add(locale, translations)
// add a new locale to the storage
// (i.e. 'de', {'message': 'Eine Nachricht'})
$i18n.exists(locale), Vue.i18n.exists(locale)
// check if the given locale translations are present in the store
$i18n.remove(locale), Vue.i18n.remove(locale)
// remove the given locale from the storeAny comments or suggestions are very welcome.
