Delete multiple resources with REST API Node.js calls

In my last blog, I shared a Node.js REST API client to create hundreds of resources (B2Bi trading partners) for testing purposes. In this blog I created a Node.js program that will delete the resources, created previously, in bulk.

This program requires the node-rest-client and async Node.js modules.

$ npm install node-rest-client

$ npm install async

In this example I used the REST API of IBM Sterling B2B Integrator to delete a 200 Sterling FileGateway Trading Partners in this format: Partner### .

You can use this Node.js code with any other REST API.

deleteMultiplePartners.js

var Client = require('node-rest-client').Client;
var async   = require('async');
//TODO: Change
var address = "http://x.x.x.x";
var port = "5074"
var apiUri = "/B2BAPIs/svc/"
var baseUri = address + ":" + port + apiUri;
//TODO: Change
var auth_info = {user:"user", password:"password"};
//Create client instance with auth info
client = new Client(auth_info);

//Define required headers
var headers = {
	"Content-Type": "application/json",
	"Accept": "application/json"
};
// set content-type header and data as json in args parameter
var args = {
       headers: headers
};
var i = 0;
var continueWhilst = true;
async.whilst(
  function test() { return continueWhilst; },
  deletePartner,
  function (err) {
  }
);
function deletePartner(next) {
   client.delete(baseUri + "tradingpartners/Partner"+i,args, function (data, response) {
   // parsed response body as js object
    console.log(data);
    // raw response
    //console.log(response);
}
);
        i += 1;  
		if (i === 200) {
		   //stop iterating 
            continueWhilst = false;
        }
        console.log("Iterating, i= " + i);
        // This is in the callback for request now.
        next();
    };

To run the program: save the code into a file and run:

node deleteMultiplePartners.js
