it comes from angular2 tutorial.
Install the npm packages described in the package.json and verify that it works:
Attention Windows Developers: You must run all of these commands in administrator mode
npm install
npm startThe npm start command first compiles the application,
then simultaneously re-compiles and runs the lite-server.
Both the compiler and the server watch for file changes.
Shut it down manually with Ctrl-C.
You're ready to write your application.
We've captured many of the most useful commands in npm scripts defined in the 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, a light-weight, static file server, written and maintained by John Papa and Christopher Martin 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.
Here are the test related scripts:
npm test- compiles, runs and watches the karma unit testsnpm run webdriver:update- ONE TIME update for protractor end-to-end (e2e) testsnpm run e2e- run protractor e2e tests, written in JavaScript (*e2e-spec.js)
