DevExtreme jQuery/JS - Localization
Localization adapts your application to linguistic and regional differences. DevExtreme allows you to localize:
- Messages (using dictionaries)
- Numbers, dates, and currencies (using Intl or Globalize).
DevExtreme also supports right-to-left layout.
Dictionaries
Dictionaries contain localized strings for different languages. The strings are key/value pairs and are shipped as JavaScript or JSON files (depending on the package you use).
All dictionaries are contributed and curated by the community. The list of dictionaries is available on GitHub.
jQuery
You can find all the dictionaries on your local machine in the DevExtreme installation folder's or ZIP archive's Lib\js\localization directory. These dictionaries are also available on CDN.
Use the <script>
tag to link the required dictionaries, and place the links after a link to the DevExtreme library:
<head> <!-- ... --> <!-- DevExtreme library --> <script src="https://cdn3.devexpress.com/jslib/24.2.3/js/dx.all.js"></script> <!-- Dictionary files for German language --> <script src="https://cdn3.devexpress.com/jslib/24.2.3/js/localization/dx.messages.de.js"></script> </head> <body> <script> DevExpress.localization.locale(navigator.language); // ... // DevExtreme UI components are configured here // ... </script> </body>
Angular
You can find all the dictionaries on your local machine in the DevExtreme installation folder's or ZIP archive's Lib\js\localization directory. These dictionaries are also available on npm.
Include the dictionaries using the import
or require
statement the statement depends on the syntax for working with modules. The following code shows ECMAScript 6 and CommonJS syntaxes:
// ... // Dictionaries for German language import deMessages from "devextreme/localization/messages/de.json"; import { locale, loadMessages } from "devextreme/localization"; export class AppComponent { constructor() { loadMessages(deMessages); locale(navigator.language); } }
// ... // Dictionaries for German language const deMessages = require('devextreme/localization/messages/de.json'); const localization = require('devextreme/localization'); localization.loadMessages(deMessages); localization.locale(navigator.language);
Vue
You can find all the dictionaries on your local machine in the DevExtreme installation folder's or ZIP archive's Lib\js\localization directory. These dictionaries are also available on npm.

// ... // Dictionaries for German language const deMessages = require('devextreme/localization/messages/de.json'); const localization = require('devextreme/localization'); localization.loadMessages(deMessages); localization.locale(navigator.language);
Create a New Dictionary
To make a dictionary for a new locale:
- Copy one of the available dictionaries.
- Rename it according to the new locale.
- Translate the strings in it and change the locale key.
You can submit JSON dictionaries to our repository on GitHub. You should refer to our Contribution Guide before submitting content.
Add Strings to a Dictionary
In the following example, the loadMessages(messages) method adds a string with the greetingMessage
key to the English and German dictionaries. The formatMessage(key, value) method then uses this key to retrieve the string from the dictionary that corresponds to the locale set by the locale(locale) method.
jQuery
$(function() { var userName = "John"; DevExpress.localization.loadMessages({ "en": { "greetingMessage": "Good morning, {0}!" }, "de": { "greetingMessage": "Guten morgen, {0}!" } }); DevExpress.localization.locale(navigator.language); $("#greeting").text( DevExpress.localization.formatMessage("greetingMessage", userName) ) })
<h1 id="greeting"></h1>
Angular
import { Component } from '@angular/core'; import { formatMessage, loadMessages, locale } from 'devextreme/localization'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { constructor() { loadMessages({ 'en': { 'greetingMessage': 'Good morning, {0}!' }, 'de': { 'greetingMessage': 'Guten morgen, {0}!' } }); locale(navigator.language); } userName: string = 'John'; get greeting() { return formatMessage('greetingMessage', this.userName); } }
<h1>{{ greeting }}</h1>
Vue
<template> <h1>{{ greeting }}</h1> </template> <script> import { formatMessage, loadMessages, locale } from 'devextreme/localization'; export default { created() { loadMessages({ 'en': { 'greetingMessage': 'Good morning, {0}!' }, 'de': { 'greetingMessage': 'Guten morgen, {0}!' } }); locale('de'); }, data() { return { userName: 'John' } }, computed: { greeting() { return formatMessage('greetingMessage', this.userName); } } } </script>
React
import React from 'react'; import { formatMessage, loadMessages, locale } from 'devextreme/localization'; class App extends React.Component { constructor(props) { super(props); this.userName = 'John'; loadMessages({ 'en': { 'greetingMessage': 'Good morning, {0}!' }, 'de': { 'greetingMessage': 'Guten morgen, {0}!' } }); this.greeting = formatMessage('greetingMessage', this.userName); locale(navigator.language); } render() { return ( <h1>{ this.greeting }</h1> ); } } export default App;
You can also see this approach in one of our demos:
Override Strings in a Dictionary
To override a string, find its key in any dictionary and use it to specify the new string value.
In the following code, we override two strings from the English dictionary:
jQuery
$(function() { DevExpress.localization.loadMessages({ "en": { "dxDataGrid-editingDeleteRow": "Remove", "dxDataGrid-editingUndeleteRow": "Recover" } }); });
Angular
import { Component } from '@angular/core'; import { loadMessages } from 'devextreme/localization'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { constructor() { loadMessages({ "en": { "dxDataGrid-editingDeleteRow": "Remove", "dxDataGrid-editingUndeleteRow": "Recover" } }); } }
Vue
<template> <!-- ... --> </template> <script> import { loadMessages } from 'devextreme/localization'; export default { created() { loadMessages({ "en": { "dxDataGrid-editingDeleteRow": "Remove", "dxDataGrid-editingUndeleteRow": "Recover" } }); } } </script>
React
import React from 'react'; import { loadMessages } from 'devextreme/localization'; class App extends React.Component { constructor(props) { super(props); loadMessages({ "en": { "dxDataGrid-editingDeleteRow": "Remove", "dxDataGrid-editingUndeleteRow": "Recover" } }); } render() { return ( { /* ... */} ); } } export default App;

Using Intl
Intl is the short name used to refer to a particular ECMAScript Internationalization API object. DevExtreme supports this API out of the box. All you need to do is set the locale:
jQuery
DevExpress.localization.locale(navigator.language); // ... // DevExtreme UI components are configured here // ...
<head> <!-- ... --> <!-- DevExtreme library --> <script src="https://cdn3.devexpress.com/jslib/24.2.3/js/dx.all.js"></script> <!-- Dictionary files for German language --> <script src="https://cdn3.devexpress.com/jslib/24.2.3/js/localization/dx.messages.de.js"></script> <script src="index.js"></script> </head>
Angular
import { Component } from '@angular/core'; // Dictionaries for German language import deMessages from "devextreme/localization/messages/de.json"; import { locale, loadMessages } from "devextreme/localization"; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { constructor() { loadMessages(deMessages); locale(navigator.language); } }
Vue
<template> <!-- ... --> </template> <script> // Dictionaries for German language import deMessages from "devextreme/localization/messages/de.json"; import { locale, loadMessages } from "devextreme/localization"; export default { created() { loadMessages(deMessages); locale(navigator.language); } } </script>
React
// Dictionaries for German language import deMessages from "devextreme/localization/messages/de.json"; import { locale, loadMessages } from "devextreme/localization"; class App extends React.Component { constructor(props) { super(props); loadMessages(deMessages); locale(navigator.language); } render() { return ( {/* ... */} ); } } export default App;
CommonJS syntax
// ... // Dictionaries for German language const deMessages = require('devextreme/localization/messages/de.json'); const localization = require('devextreme/localization'); localization.loadMessages(deMessages); localization.locale(navigator.language);
If you want to format and localize strings, numbers, dates, and currencies automatically according to the specified locale, define the format.type property. You can also specify a currency other than USD globally. For this purpose, use the defaultCurrency or currency settings:
jQuery
$(function() { // Specifying a currency globally DevExpress.config({ defaultCurrency: "EUR" }); $("#dataGridContainer").dxDataGrid({ // ... columns: [{ dataField: "Price", // Specifying a currency in a format definition format: { type: "currency", currency: "RUB" } }] }); });
Angular
import { Component } from '@angular/core'; import config from 'devextreme/core/config'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { constructor() { // Specifying a currency globally config({ defaultCurrency: 'EUR' }); } }
<dx-data-grid ... > <dxi-column dataField="price"> <!-- Specifying a currency in a format definition --> <dxo-format type="currency" currency="RUB"> </dxo-format> </dxi-column> </dx-data-grid>
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxDataGridModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxDataGridModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxDataGrid ... > <DxColumn data-field="price"> <!-- Specifying a currency in a format definition --> <DxFormat type="currency" currency="RUB" /> </DxColumn> </DxDataGrid> </template> <script> import 'devextreme/dist/css/dx.light.css'; import config from 'devextreme/core/config'; import DxDataGrid, { DxColumn, DxFormat } from 'devextreme-vue/data-grid'; export default { components: { DxDataGrid, DxColumn, DxFormat }, created() { // Specifying a currency globally config({ defaultCurrency: 'EUR' }); } } </script>
React
import React from 'react'; import config from 'devextreme/core/config'; import 'devextreme/dist/css/dx.light.css'; import DataGrid, { Column, Format } from 'devextreme-react/data-grid'; class App extends React.Component { constructor(props) { super(props); // Specifying a currency globally config({ defaultCurrency: 'EUR' }); } render() { return ( <DataGrid ... > <Column dataField="price"> // Specifying a currency in a format definition <Format type="currency" currency="RUB" /> </Column> </DataGrid> ); } } export default App;
You can use structures compatible with the Intl API for value formatting. Refer to the Intl Formats section in the Value Formatting article for more information.
Using Globalize
React
The following files are required to activate Globalize in your project:
- Globalize library
- CLDR library
- CLDR data
To include these components, you can use CDN or npm.
CDN or local files
Specify the Globalize and CLDR libraries using
<script>
tags as shown below. In this example, the German dictionary is included. Note that the order in which you include the libraries is important. Then, set the locale using theGlobalize.locale()
method:CDN
HTML<head> <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script> <!-- ... --> <script src="https://cdnjs.cloudflare.com/ajax/libs/cldrjs/0.5.0/cldr.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/cldrjs/0.5.0/cldr/event.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/cldrjs/0.5.0/cldr/supplemental.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/globalize/1.3.0/globalize.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/globalize/1.3.0/globalize/message.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/globalize/1.3.0/globalize/number.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/globalize/1.3.0/globalize/currency.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/globalize/1.3.0/globalize/date.min.js"></script> <!-- DevExtreme library --> <script src="https://cdn3.devexpress.com/jslib/24.2.3/js/dx.all.js"></script> <!-- Dictionary files for German language --> <script src="https://cdn3.devexpress.com/jslib/24.2.3/js/localization/dx.messages.de.js"></script> <!-- Common and language-specific CLDR data --> <script src="https://unpkg.com/devextreme-cldr-data/supplemental.js"></script> <script src="https://unpkg.com/devextreme-cldr-data/de.js"></script> </head> <script> $(function() { Globalize.locale(navigator.language); }); </script>
npm
Install the
devextreme-cldr-data
andglobalize
packages:npm install --save-dev devextreme-cldr-data globalize
Angular
Register Globalize in your project as described in the following help topic: Globalize Registration.
Vue
Register Globalize in your project as described in the following help topic: Globalize Registration.
React
Register Globalize in your project as described in the following help topic: Additional Configuration for Webpack.
Then, include Globalize, CLDR, and language-specific CLDR data using the
import
orrequire
statement—the statement depends on the syntax for working with modules. The code below shows ECMAScript 6 and CommonJS syntaxes. These examples include the German dictionary.npm: ECMAScript 6 syntax
JavaScriptimport "devextreme/localization/globalize/number"; import "devextreme/localization/globalize/date"; import "devextreme/localization/globalize/currency"; import "devextreme/localization/globalize/message"; // Dictionaries for the German language import deMessages from "devextreme/localization/messages/de.json"; // Common and language-specific CLDR JSONs import supplemental from "devextreme-cldr-data/supplemental.json"; import deCldrData from "devextreme-cldr-data/de.json"; import Globalize from "globalize"; // ===== Angular ====== export class AppComponent { constructor() { Globalize.load( supplemental, deCldrData ); Globalize.loadMessages(deMessages); Globalize.locale(navigator.language); } } // ===== Vue ====== export default { created() { Globalize.load( supplemental, deCldrData ); Globalize.loadMessages(deMessages); Globalize.locale(navigator.language); } } // ===== React ====== class App extends React.Component { constructor(props) { super(props); Globalize.load( supplemental, deCldrData ); Globalize.loadMessages(deMessages); Globalize.locale(navigator.language); } }

You can format and localize strings, numbers, dates, and currencies automatically according to a locale. For this, apply the format.type property. You can also use a currency other than USD (see the last example in the Using Intl topic).
In addition, you can now format values using structures accepted by numberFormatter, currencyFormatter, and dateFormatter, for example:
jQuery
$(function() { $("#dataGridContainer").dxDataGrid({ // ... columns: [{ dataField: "OrderDate", format: { skeleton: "yMMMd" } }, { dataField: "SaleAmount", format: { currency: "EUR", maximumFractionDigits: 2 } }] }); });
Angular
<dx-data-grid ... > <dxi-column dataField="OrderDate" [format]="{ skeleton: 'yMMMd' }"> </dxi-column> <dxi-column dataField="SaleAmount" [format]="{ currency: 'EUR', maximumFractionDigits: 2 }"> </dxi-column> </dx-data-grid>
import { Component } from '@angular/core'; // ... // import dictionaries and localization modules here @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { // ... }
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxDataGridModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxDataGridModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxDataGrid ... > <DxColumn data-field="OrderDate" :format="{ skeleton: 'yMMMd' }" /> <DxColumn data-field="SaleAmount" :format="{ currency: 'EUR', maximumFractionDigits: 2 }" /> </DxDataGrid> </template> <script> import 'devextreme/dist/css/dx.light.css'; // ... // import dictionaries and localization modules here import DxDataGrid, { DxColumn } from 'devextreme-vue/data-grid'; export default { components: { DxDataGrid, DxColumn }, // ... } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import DataGrid, { Column } from 'devextreme-react/data-grid'; // ... // import dictionaries and localization modules here class App extends React.Component { constructor(props) { super(props); // ... } render() { return ( <DataGrid ... > <Column dataField="price" format={{ currency: 'EUR', maximumFractionDigits: 2 }} /> </DataGrid> ); } } export default App;

Localize Custom Values
DevExtreme provides an API for localizing messages, dates, and numbers in your app.
To localize a message, add it to a dictionary as shown in the Add Strings to a Dictionary article.
To localize a custom date or number, apply a format to it as shown in the Format Custom Values article.
Right-to-Left Support
Right-to-left (RTL) support allows the UI component to adapt its content to right-to-left locales.
RTL layout can be specified for an individual UI component using its rtlEnabled property:
jQuery
$(function() { $("#sliderContainer").dxSlider({ // ... rtlEnabled: true }); });
Angular
<dx-slider ... [rtlEnabled]="true"> </dx-slider>
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { // ... }
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxSliderModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxSliderModule ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxSlider ... :rtl-enabled="true" /> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxSlider from 'devextreme-vue/slider'; export default { components: { DxSlider } } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import Slider from 'devextreme-react/slider'; class App extends React.Component { render() { return ( <Slider ... rtlEnabled={true} /> ); } } export default App;
To apply RTL to your entire application, set the same property globally using the config() function:
jQuery
$(function() { DevExpress.config({ rtlEnabled: true }); // ... });
Angular
import { Component } from '@angular/core'; import config from 'devextreme/core/config'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { constructor() { config({ rtlEnabled: true }); } }
Vue
<template> <!-- ... --> </template> <script> import config from 'devextreme/core/config'; export default { // ... created() { config({ rtlEnabled: true }); } } </script>
React
import React from 'react'; import config from 'devextreme/core/config'; class App extends React.Component { constructor(props) { super(props); config({ rtlEnabled: true }); } render() { return ( // ... ); } } export default App;
