express-language v0.0.2

express-lang

A simple way to change the language of the web.

Example:

var express = require('express');
var expressLang = require(__dirname + '\express-lang.js');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var app = express();

var opts = {
	method : 'cookie',
	name : 'lang',
	supported_lang : ['es','en','gr'],
	getStrings : function(req,res,cb){
		//Code to load language strings to req.lang_strings
		cb();
	}
}
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(expressLang.middleware(opts));

NPM install

you can install it using npm:

var expressLang = require('express-language');
