FAC—REST API structure and files

Follow the instructions in this section to create the environment in which you can explore the REST API.
This example uses the Campaign Conversion app in a local installation of Xpress Insight.
To explore the file structure, and install node.js, perform the following steps:
  1. In Windows Explorer, navigate to <Xpress Install Directory>\examples\insight\rest_api\rest-client-example\.
    The three files, package.json, rest-client-example.js, and dmp-rest-client-example.js, are contained in this directory—This example uses package.json and dmp-rest-client-example.js.

    The package.json file contains some Node.js configuration—specifically calling for the request and prequest modules. request is a simplified HTTP client with HTTPS support, while prequest offers HTTP requests with promises. You can investigate them further at http://github.com/request/request and https://github.com/alyssaq/prequest respectively. 

    {
  "name": "rest-client-example",
  "version": "1.0.0",
  "author": "FICO",
  "devDependencies": {
    "prequest": "^1.0.0",
    "request": "^2.75.0"
  }
}

    The dmp-rest-client-example.js file contains the example code itself.

  2. Open a Command Prompt window, navigate to the rest-client-example directory.
  3. Type npm install and press Enter to obtain the prerequisites and download them into node_modules.
    The node_modules folder is added to your rest-client-example directory.
