Runtime (dw::Runtime)

DataWeave 2.2 is compatible and bundled with Mule 4.2. Standard Support for Mule 4.2 ended on May 2, 2021, and this version of Mule will reach its End of Life on May 2, 2023, when Extended Support ends.

Deployments of new applications to CloudHub that use this version of Mule are no longer allowed. Only in-place updates to applications are permitted.

MuleSoft recommends that you upgrade to the latest version of Mule 4 that is in Standard Support so that your applications run with the latest fixes and security enhancements.

This module contains functions that allow you to interact with the DataWeave engine.

To use this module, you must import it to your DataWeave code, for example, by adding the line import * from dw::Runtime to the header of your DataWeave script.
