Prebid.js Module Overview

The core of Prebid.js contains only the foundational code needed for header bidding. Any functionality that could be considered an add-on is part of a module. These are the major categories:

Prebid.org highly recommends that publishers utilize the following modules:

Module Description
Consent Management - GDPR If you have users in Europe, this module works with your Consent Management Platform to pass consent info to bidders and help align with EU regulations. See also the GDPR Enforcement module.
Consent Management - GPP If you have users in regions of the world that adhere to the Global Privacy Platform, this module works with your Consent Management Platform to pass consent info to bidders and help align with regional regulations.
Consent Management - US Privacy If you have users in California, this module works with your Consent Management Platform to pass CCPA/US-Privacy data to bidders.
First Party Data Enrichment Injects additional data into the auction stream, including: domain, keywords, and page url.

General Modules

Modules in the Real-Time Data (RTD) category conform to a consistent set of publisher controls. The publisher can choose to run multiple RTD modules, define an overall amount of time they’re willing to wait for results, and even flag some of the modules as being higher priority than others.
