Node.js and npm are essential to Angular 2 development.
Get it now if it's not already installed on your machine.Verify that you are running at least node v4.x.x and npm 3.x.x
by running node -v and npm -v in a terminal/console window.
Older versions produce errors.
We recommend nvm for managing multiple versions of node and npm.
Clone this repo into new project folder (e.g., my-proj).
git clone https://github.com/angular/quickstart my-proj
cd my-projSee npm and nvm version notes above
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 startIf the
typingsfolder doesn't show up afternpm installplease install them manually with:
npm run typings -- install
The 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 e2e- run protractor e2e tests, written in JavaScript (*e2e-spec.js)
