Node: Synchronous/Blocking HTTP Request

blocking-request.js

// In the rare case you actually want a syncronous request
// this will wait until the data arrives before continuing
// down the file.
//
// The service where this is used fetches configuration data
// from an external service in order to run.

const axios = require('axios')

// Output:
// making request
// completed request
// continuing execution
// 200 OK
