14 Typescript (2) with jquery, bootstrap and other module stuff

Imagen
1. Introduction Modules are rather tedious and difficult to be understood. There are many module types (Commonjs, AMD, UMD, System) as Jurgen Van Moere explains.  Node, however, works well with Commonjs modules but cannot integrate well with other modules (AMD, System..) Webpack comes to the rescue, but it is a bit difficult to use. With the help of some sites like Neoguias  and  Swashbuckling  this task is much more easier. Our schedule is: Create the basics Create a simple web page with html and javascript Creating a simple module Importing and using a simple node module (is-what) and @types Importing and using jquery 1.

05. Resource bundles (i18n)

Imagen
 1. Introduction There are several ways to use resource bundles. By now, let's use  java  instead of xml ( <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" % > ) 1. First lay the resource files ( main _ language .properties ) in the folder  src/main/resources/i18n 2. Create a jsp file 3. Add a new page directive with the includes ( Locale y ResourceBundle ) 4. Get the locale from the request and the resource bundle from the relative path " i18n/main " 5. Assign the localized value using   <%=bundle.getString("key") %> The source code is <%@ page language = "java" contentType = "text/html; charset=UTF-8" pageEncoding = "UTF-8" %> <%@ page import = " java.io.* , java . util .
