example.js

console.log(__("Hello World"));
console.log(__("Missing Text"));

webpack.config.js

var I18nPlugin = require("i18n-webpack-plugin");
module.exports = {
	plugins: [
		new I18nPlugin(
			require("./de.json") // or pass null to use defaults
		)
	]
}

I recommend to use new I18nPlugin(null) for development and write a small script that generates bundles for every language

de.json

{
	"Hello World": "Hallo Welt"
}

js/output.js

(function(modules) { // webpackBootstrap
// The module cache
var installedModules = {};

// The require function
function require(moduleId) {
	// Check if module is in cache
	if(installedModules[moduleId])
		return installedModules[moduleId].exports;
	
	// Create a new module (and put it into the cache)
	var module = installedModules[moduleId] = {
		exports: {},
		id: moduleId,
		loaded: false
	};
	
	// Execute the module function
	modules[moduleId].call(null, module, module.exports, require);
	
	// Flag the module as loaded
	module.loaded = true;
	
	// Return the exports of the module
	return module.exports;
}

require.e = function requireEnsure(_, callback) {
	callback.call(null, require);
};
require.modules = modules;
require.cache = installedModules;


// Load entry module and return exports
return require(0);
})
