javascript - Express.js multilanguage with i18n-node -

how call controller express.js routing?

app.get('*', function(req, res, next) {     var regexp = /^\/([a-z]{2})(\/|$)/gi,         exec = regexp.exec(req.url);      exec = exec != null ? exec[1] : undefined;      if(exec == undefined) {         // add language prefix link     }     else {         i18n.setlocale(exec);         // add language prefix link     }     next(); }); 

if open page /about need url this: http://example.com/en/about. how can , how display call 'about' controller?

app.get('/about', function(req, res) {     console.log('here about');     res.send('hello, world'); }); 

not suitable: app.get('(en|de|ru)/about', ...)

thanks in advance.

you like

app.get('/:language/about', function(req, res) {     var language = req.params.language;     i18n.setlocale(language); }); 

for multiple routes maybe this

controllers.js

module.exports = {     about: function(req, res) {         res.send('about');     } } 

app.js

var controllers = require('./controllers'); app.all('/:language/:controller', function(req, res) {     i18n.setlocale(req.params.language);     controllers[req.params.controller](req, res); });
