Express Loadmill

Users of Loadmill can use this express middleware for:

1. Quick and easy domain verification.
2. Enabling CORS strictly from loadmill.com in order to perform crowdsourced load tests.

Installation

Using npm:

npm install express-loadmill --save

Using yarn:

yarn add express-loadmill

Usage

Use loadmill middleware before everything else (that should be exposed to testing):

var app = require('express')();
var Loadmill = require('express-loadmill');

app.use(Loadmill({verifyToken: process.env.LOADMILL_VERIFY_TOKEN}));

The above code enables both CORS and domain verification. You may optionally disable CORS by setting the enableCors option to false, e.g.

app.use(Loadmill({enableCors: false, verifyToken: process.env.LOADMILL_VERIFY_TOKEN}));

Note however that you will not be able to perform high-volume load tests with loadmill without enabling CORS.

Domain verification will only be enabled if you supply a verification token, thus the following code will only enable CORS:

app.use(Loadmill());

Cookies

To enable cookies being sent to and from the server (by setting Access-Control-Allow-Credentials response header), set the enableCookies option to true, e.g.

app.use(Loadmill({enableCookies: true, verifyToken: process.env.LOADMILL_VERIFY_TOKEN}));

Note that you will also need to enable cookies for your test in the Advanced Settings section of your test configuration.
