This lesson shows you how to install TypeScript and run the TypeScript compiler against a .ts file from the command line.

 

install:

npm install -g typescripttsc -v // version

 

app.ts:

class Person{}

 

RUN:

tsc app.ts

You will see the js file with the same name.

 

If you want a different name, you can do :

tsc --out 
      
      
       tsc --out bundle.js app.ts
      
     

 

Watch files changes:

tsc -w --out bundle.js app.ts
