Dynamic data collection with Zaraz Worker Variables

Cloudflare Workers is a powerful platform to build and deploy serverless functions, allowing developers to execute custom code in response to various events triggered by users interacting with their websites. By integrating Zaraz, the data management layer for your website, you can pass important user context from the edge to your workers, enabling more complex operations such as aggregation of data or enrichment of user profiles with external APIs. In this tutorial, we've seen how to define a Worker Variable and use it within our code. We've also provided two examples: translating a GTM Custom JavaScript variable into a Cloudflare Zaraz Worker variable, and enriching user information with data coming from an API. To start using Worker Variables, you first need to create a new Cloudflare Worker and configure it with the appropriate permissions. Then, you can easily integrate them within your Zaraz tools configuration. Overall, Cloudflare Workers offer great flexibility and power for building advanced data processing capabilities in serverless environments, making it easier than ever to develop complex applications that require custom logic at different points in their workflow.
