Answer 1

the i flag is for install. From documentation:

npm install
npm install <pkg>
npm install <pkg>@<tag>
npm install <pkg>@<version>
npm install <pkg>@<version range>
npm install <folder>
npm install <tarball file>
npm install <tarball url>
npm install <git:// url>
npm install <github username>/<github project>

Can specify one or more: npm install ./foo.tgz bar@stable /some/folder
If no argument is supplied and ./npm-shrinkwrap.json is 
present, installs dependencies specified in the shrinkwrap.
Otherwise, installs dependencies from ./package.json.

The i is npm-install alias which is mentioned in https://docs.npmjs.com/cli/install.

npm i angular2@2.0.0-alpha.45 --save --save-exact
npm i live-server --save-dev
