# Controller Localization
## Accessing Current Locale
```javascript
var Locale = require('dw/util/Locale');
server.get('Show', function (req, res, next) {
var current = Locale.getLocale(req.locale.id);
res.render('mytemplate', {
locale: req.locale.id,
language: current.language,
country: current.country
});
next();
});
```
## Locale-Specific Logic
```javascript
server.get('Checkout', function (req, res, next) {
var locale = req.locale.id;
var dateFormat = locale.startsWith('en_US') ? 'MM/dd/yyyy' : 'dd/MM/yyyy';
res.render('checkout', { dateFormat: dateFormat });
next();
});
```
## Localized Errors / JSON Responses
```javascript
var Resource = require('dw/web/Resource');
server.post('Submit', function (req, res, next) {
if (!server.forms.getForm('profile').valid) {
res.json({ success: false, message: Resource.msg('error.form.invalid', 'error', 'Please correct the errors') });
return next();
}
res.json({ success: true, message: Resource.msg('message.saved', 'common', 'Saved successfully') });
next();
});
```
## Email Templates
```javascript
var Template = require('dw/util/Template');
var Mail = require('dw/net/Mail');
var HashMap = require('dw/util/HashMap');
var Resource = require('dw/web/Resource');
function sendOrderConfirmation(order, locale) {
var template = new Template('mail/orderconfirmation', locale);
var model = new HashMap();
model.put('order', order);
var content = template.render(model).text;
var mail = new Mail();
mail.addTo(order.customerEmail);
mail.setSubject(Resource.msg('email.order.subject', 'email', null));
mail.setContent(content, 'text/html', 'UTF-8');
mail.send();
}
```
