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.
See 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 start
If the
typings
folder doesn't show up afternpm install
please 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.
