How does angular installed through nodeJs deploy into the project and build with gulp

  node.js, question

For projects built with gulp, angularjs is installed through npm. How can angular.min.js be deployed into the project folder?
For example:

I have a project called TestApp. gulp and angular are installed through npm. there is src\js folder under testApp, but angular.min.js is in node_modules\angular. how can I export it to src\js folder through gulp?
