project_root/tsconfig.json
 /scripts
   /ts

 /tests
   /ts
   /js
   /doc

Making a tsconfig.json file:

http://techiejs.com/Blog/Post/Leveraging-tsconfigjson-in-TypeScript-projects

https://github.com/Microsoft/TypeScript/wiki/tsconfig.json

Very basic for the above structure:

 {
  "compilerOptions": {
     "target": "es5",
     "module": "commonjs",
     "declaration": false,
     "noImplicitAny": false,
     "removeComments": true,
     "noLib": false,
     "outDir": "scripts/js"
   }
}

Linting

tslint with standard unix formatter

sudo npm -g install tslint
npm install tslint-unix-formatter

Calls to the linter should then be made with:

tslint -t unix -s ~/node_modules/tslint-unix-formatter/lib/

Setup and edit a tslint.json file for configuration.

gjslint

One can also use gjslint as this offers the fixjsstyle option.

sudo npm -g install gjslint
apt-get install closure-linter
