### Start development Install the npm packages described in the `package.json` and verify that it works: ```bash $ npm install $ bower install $ npm start ``` You're ready to write your application. Remember the npm scripts in `package.json`: * `npm start` - runs the compiler and a server at the same time, both in "watch mode". * `npm run tsc` - runs the TypeScript compiler once. * `npm run tsc:w` - runs the TypeScript compiler in watch mode; the process keeps running, awaiting changes to TypeScript files and re-compiling when it sees them. * `npm run lite` - runs the [lite-server](https://www.npmjs.com/package/lite-server), a light-weight, static file server, written and maintained by [John Papa](https://github.com/johnpapa) and [Christopher Martin](https://github.com/cgmartin) with excellent support for Angular apps that use routing. * `npm run typings` - runs the typings tool. * `npm run postinstall` - called by *npm* automatically *after* it successfully completes package installation. This script installs the TypeScript definition files this app requires.
