Typescript Training tho.

It's required to have installed at least Node.JS version 6.

Install typescript via npm:

npm i -g typescript

To run a command transforming your ts file into js file, execute:

tsc <filename>.ts

It's gonna create a <filename>.js file.

You can also watch this file running:

tsc -w <filename>.ts

It's gonna print something like:

00:38:11 - Starting compilation in watch mode...
00:38:14 - Compilation complete. Watching for file changes.

Finally, you can execute your js file running:

node <filename>.js

You can specify how your typescript will be executed. For example, I want to execute different from default, and transpile it through ES6:

tsc -t ES6 -w hello.ts

We can define it from a configuration file. To init it, just run:

tsc --init

This will create a tsconfig.json file which tells typescript how to execute ts commands.

Now, just run tsc -w and typescript will watch and transpile every single ts file on your project.
