Sailsjs change localization

You can always change the locale in a controller action by using req.setLocale() or by setting the value of req.locale. You can also handle this more globally by using a policy:

// config/routes.js

module.export.routes = {

  '/:lang/': 'MyController.index',
  '/:lang/help': 'MyController.help',
  '/:lang/contact': 'MyController.contact',
  ...etc...

}

---

// config/policies.js

module.exports.policies = {

   '*' : 'localize'

}

---

// api/policies/localize.js

module.exports = function(req, res, next) {

   req.locale=req.param('lang');
   next();

};

Update 2020 to @sgress454's answer

// api/policies/localize.js`

module.exports = function(req, res, next) {
  // This worked for testing
  // You can use req.param('lang') instead of 'in'
  req.setLocale('in');
  next();

};
