Skip to Scheduled Dates

Course Overview

Discover how to build complex data transformations in Anypoint Platform with DataWeave. In this 2-day instructor-led course, learn how to write simple, reusable transformations using variables, functions, and DataWeave modules, and how to customize complex data structures, including nested arrays, objects, and arrays of objects.

Who Should Attend

  • This course is designed for MuleSoft developers or architects who are responsible for building complex data transformations in Anypoint Platform with DataWeave.

Course Objectives

    • Write simple, reusable transformations using variables, functions, and DataWeave modules.
    • Use the DataWeave Playground to write and test DataWeave code.
    • Build complex transformations from smaller, testable steps.
    • Configure robust and testable functions and expressions with strong typing, match operators, error handling, and logging.
    • Customize complex data structures, including nested arrays, objects, and arrays of objects.
    • Format or replace nested schema elements.
    • Calculate key performance indicators (KPI) in order to reduce arrays to other data structures or data types.
