This is about getting started with TypeScript.
What does a simple web app with a well known third party library look like?
TypeScript is about maintainability of large applications. Large applications should be written as modules, how does TypeScript work with modules?
Angular 2 is written in TypeScript, let's take it for a spin!
The labs require a fairly new version of npm (at least > 3.0), at least if you want typings installed with npm. If you have a good version of npm installed all is fine, you can compile the TypeScript code by running the npm scripts of the project:
>npm run tsc
(after installing typescript of course, npm install,
also, see the package.json file for the npm scripts available).
If you don't have a new version of npm you can install it locally by:
>npm install npm
and to have that version first on your path:
>export PATH=$(npm bin):$PATH
Then you can run the npm commands as above, install all dependencies by
>npm install
and off you go!
(All this assumes a unix like environment. Are you on Windows? Well then you are probably up to date with the latest and greatest.)
