I18n fro koa, based on i18n-2. NOTE: If want to use koa-i18n, koa-locale must be requred!

Installation

$ npm install koa-i18n

Usage

var app = require('koa')();
var locale = require('koa-locale'); //  detect the locale
var render = require('koa-swig');   //  swig render
var i18n = require('koa-i18n');

// Required!
locale(app);

render(app, {
  root: __dirname + '/views/',
  ext: 'html'
});

app.use(i18n(app, {
  directory: './config/locales',
  locales: ['zh-CN', 'en'], //  `zh-CN` defualtLocale, must match the locales to the filenames
  modes: [
    'query',                //  optional detect querystring - `/?locale=en-US`
    'subdomain',            //  optional detect subdomain   - `zh-CN.koajs.com`
    'cookie',               //  optional detect cookie      - `Cookie: locale=zh-TW`
    'header',               //  optional detect header      - `Accept-Language: zh-CN,zh;q=0.5`
    'url',                  //  optional detect url         - `/en`
    'tld'                   //  optional detect tld(the last domain) - `koajs.cn`
  ]
}));

app.use(function *(next) {
  this.body = this.i18n.__('any key');
});

app.use(function *(next) {
  yield this.render('index')
});

Tip: We can change position of the elements in the modes array. If one mode is detected, no continue to detect.
