Leveraging Corellium and Cloudflare Workers for iOS Virtual Device Management
As the demand for testing and managing iOS applications grows, developers are increasingly looking for efficient and scalable ways to work with remote iOS devices. In our previous blog post, we demonstrated how to use Python with an AWS Lambda in conjunction with Corellium to create a powerful, serverless solution for managing and testing iOS applications. In this blog post, we will explore a different approach, using TypeScript with Cloudflare Workers, to achieve similar results with the added benefits of Cloudflare's edge computing infrastructure.
In the following sections, we will walk through the steps to set up a Cloudflare Worker, configure it to interact with the Corellium API, and demonstrate a simple integration to help get you started. This approach offers an alternative to the AWS Lambda method, giving developers more options and flexibility when choosing the right serverless platform for their specific needs. We'll cover the following topics:

Security considerations and best practices
1. Introduction to Corellium and Cloudflare Workers
Corellium is a platform that allows developers to create and manage virtual iOS devices for testing, debugging, and security research purposes. With Corellium, you can create an iOS device with a specific version, model, and configuration, which makes it an invaluable tool for developers working on iOS applications.
Cloudflare Workers are a serverless computing platform that enables developers to run their code directly at the edge of Cloudflare's global network. This allows for faster execution and reduced latency, as the code is running closer to the end-users and developers. Cloudflare Workers can be used for a wide variety of applications, such as custom logic implementation, API proxying, and task automation.
2. Setting up Corellium virtual iOS devices
To start using Corellium, you'll first need to create an account and set up a virtual iOS device. Follow these steps:
Sign up for a Corellium account at https://corellium.com/.
Log in to your Corellium account and navigate to the "Devices" tab.
Click "Add Device" and select the iOS device model, iOS version, and any other necessary configurations for your virtual device.
Click "Create" to instantiate the virtual device. It may take a few minutes for the device to become available.
Once your virtual iOS device is ready, you can interact with it using the Corellium web interface or API.
3. Creating a Cloudflare Worker
If this is your first time writing a Cloudflare Worker, you'll need to follow a basic installation guide to ensure you have all the needed dependencies and tools. https://developers.cloudflare.com/workers/get-started/guide/
Once you've gotten the Workers CLI install, you can create a Cloudflare Worker by simply running:
npx wrangler init corellium-blog-20230417
4. Integrating Corellium with Cloudflare Workers
To integrate Corellium with Cloudflare Workers, you'll need to interact with Corellium's API to manage your virtual iOS devices. (While Corellium has a helper npm package, it currently does not have TypeScript bindings as of the time of writing, though this will likely be changed in the upcoming weeks.)
Obtain an API token from your Corellium account. Navigate to your profile settings and click "API Tokens."
Create a new token and copy it. This token will be used to authenticate your requests to the Corellium API.
Next, grab the instance ID of the virtual device you created earlier. You can find it in the URL.
Now that we have everything needed to write our first "Hello Corellium" script! This is what we're going to put in for our `src/index.ts` file.
