Create a new angular project with @angular/cli and yarn

angular-cli+yarn.md

Tell ng to use yarn all the times:

$ ng set --global packageManager=yarn

Create a new angular4 project:

$ ng new myapp --ng4 --routing --style=scss

By configuring yarn as THE package manager in advance, we don't have to deactivate the install phase and do it manually:

$ ng new myapp --ng4 --routing --skip-install
$ cd myapp
$ yarn

By default, ng will create a git repository and a first commit.

ng config -g cli.packageManager yarn
