Nathan Rozentals has been writing commercial software for over 30 years, in C, C++, Java and C#. He picked up TypeScript within a week after its initial release in October 2012 and realized how much TypeScript could help when writing JavaScript. He was one of the first people to start blogging about TypeScript, discussing early frameworks such as Backbone, Marionette, ExtJS and AngularJs. He knew he'd hit the mark when Microsoft staff started to reference his blog posts in their CodePlex discussion forums. Nathan's TypeScript solutions now control User Interfaces in IoT devices, run as stand-alone applications for Point-of-Sale solutions, provide complex application configuration web sites, and are used for mission-critical server APIs.

Modules

Modularization is a popular technique used in programming languages that allows programs to be built from a series of smaller libraries, or modules. This technique is also applied to object-oriented code bases, where each class is typically housed in its own file. When referencing classes that exist in another source file, we need a mechanism for the TypeScript compiler, as well as the JavaScript runtime, to be able to locate the class that we are referencing. This is where modules are used.

TypeScript has adopted the module syntax that is part of ES2015. This means that we can use this syntax when working with modules, and the compiler will generate the relevant JavaScript to support modules based on the target JavaScript version we have selected. There is no change in syntax, and there is no change in our code in order to support earlier versions of the JavaScript runtime.

In this section of the chapter, we will walk through the module syntax, and discuss how to...
