<%= lingua.content.description %> \n ```\n\n b. **Use lingua in your views - Dynamic output** - Sometimes it is necessary to handle dynamic data within your express route and pass it to the template. What if your i18n resource includes placeholders (\"{key}\") within a string where you can put in your dynamic data? Well, it is possible. First of all, look at this i18n resource file:\n\n ```javascript\n // de.json\n {\n \"greeting\": \"Hallo {name}. Dieser Schlüssel {code} wurde für Dich generiert.\"\n }\n ```\n\n Now it is possible to transfer an object from your route into your template:\n\n ```javascript\n app.get('/', function(req, res) {\n var names = ['Sarah', 'Thomas', 'Claudia'];\n\n res.render('index', {\n person: {\n name: names[Math.floor(Math.random()*names.length)],\n code: Math.round(Math.random()*100)\n }\n });\n });\n ```\n\n And finally you can execute the i18n resource (yes, you can execute it (: ) and pass your data model to this function:\n\n ```html\n
<%= lingua.greeting(person) %>
\n ```\n\n _Note:_ Every i18n resource which contains placeholders like in the example above is a function after you've started the application.\n\n4. **Let the user select a language** - Note that the user's selection is persisted within a cookie. This is an optional step. If you want to let lingua determine the user language from the browser configuration then leave this step out. Anyway, this is a very handy feature for switching the language by a user decision.\n\n ```html\n de-DE\n en-US\n ```\n\n You can configure lingua in order to change the name of this parameter.\n\n ```javascript\n\n // Express app configuration code and lingua init.\n app.configure(function() {\n ...\n\n // Lingua configuration\n app.use(lingua(app, {\n defaultLocale: 'en',\n path: __dirname + '/i18n',\n storageKey: 'lang' // http://domain.tld/?lang=de\n }));\n\n ...\n });\n ```\n\n The cookie lingua uses expires in one year, and includes the httpOnly flag to prevent clientside access from Javascript. You can override these settings by providing a cookieOptions key during configuration.\n\n ```javascript\n\n // Express app configuration code and lingua init.\n app.configure(function() {\n ...\n\n // Lingua configuration\n app.use(lingua(app, {\n defaultLocale: 'en',\n path: __dirname + '/i18n',\n storageKey: 'lang', // http://domain.tld/?lang=de\n cookieOptions: {\n domain: '.domain.tld', // to allow subdomains access to the same cookie, for instance\n path: '/blog', // to restrict the language cookie to a path\n httpOnly: false, // if you need access to this cookie from javascript on the client\n expires: new Date(Date.now() + 24 * 60 * 60 * 1000), // expire in 1 day instead of 1 year\n secure: true // for serving over https\n }\n }));\n\n ...\n });\n ```\n\n \n\n\n## Example Application\n\nThere is an example application at [./example](https://github.com/akoenig/express-lingua/tree/master/example)\n\nTo run it:\n\n $ cd example\n $ node app.js\n\nYou can find a deployed version of this app [here](http://lingua-demo.herokuapp.com/).\n\n## License\n\n[MIT License](http://www.opensource.org/licenses/mit-license.php)\n\n## Author\n\nCopyright (c) 2013, [André König](http://iam.andrekoenig.info)","homepage":"https://github.com/akoenig/express-lingua","bugs":{"url":"https://github.com/akoenig/express-lingua/issues"},"license":"MIT","readmeFilename":"README.md"}
