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: highly recommends that publishers utilize the following modules:

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. See the realTimeData setConfig reference for more details.
