Deregister services in Consul when they get messy

CleanConsul.js

var request = require('request');


var HOST = "http://127.0.0.1:8500";
var SERVICE_LIST = "/v1/agent/services";
var SERVICE_DEREGISTER = "/v1/agent/service/deregister/";


request(HOST + SERVICE_LIST, (error, response, body) =>
{
    if (error || response.statusCode != 200) {
        console.log("ERROR: status code: " + response.statusCode);
        console.log(error);
    }
    else {
        var services = JSON.parse(body);

        deregisterServices(services);
    }
});

            console.log("Status: " + response.statusCode);
