The document outlines the use of polyglot mule transformers, enabling the coexistence of various programming languages for data transformation tasks within Anypoint Studio. It discusses the ability to chain transformers, employ DataWeave for specific cases, and build custom components in languages such as Java, .NET, Groovy, JavaScript, Python, and Ruby. Additionally, it details the setup and usage of scripting components, showcasing how developers can manipulate properties and execute configurations effectively.

1. POLYGLOT MULE TRANSFORMERS
ALLOWS DIFFERENT PROGRAMMING LANGUAGES COEXIST

2. BASIC CONSIDERATIONS
• Anypoint Studio provides a set of transformers to
handle the most common data transformation
scenarios
• Developer can chain transformers if a transformer did
not exist for specific needs
• The DataWeave Transform Message component can be
used in place of most other transformers

3. SPECIAL CASES
• Transforming complex data structures
• Applying complex business rules
• The available transformers cannot meet the
requirement
• Simply throw the old lines of code into a component
instead of having to reengineer the code’s behavior
through a series of different Mule components

4. POSSIBLE SOLUTIONS
• Building custom components and/or transformers
• Turning to the most favorite Programming Languages:
o Java
o .NET
o Scripting languages: Groovy, Javascript, Python or Ruby

5. JAVA

6. .NET

7. SCRIPT COMPONENT (1/2)
Basic usage: To set up in the scripting component,
identify what scripting engine to use, and the script
itself, which you can reference or type directly into the
element.

8. SCRIPT COMPONENT (2/2)
Choose a
programming
language for the
scripting component:
• Groovy
• JavaScript
• Python
• Ruby

9. SCRIPT ENGINE: GROOVY (1/2)
Placing a Groovy (JavaScript, Python, or Ruby)
Component is actually the same as placing a Script
component and then selecting the Groovy (JavaScript,
Python, or Ruby) engine.

10. SCRIPT ENGINE: GROOVY (2/2)
Specify the file
location of the script
or simply type in the
script on the script
text window.

11. SCRIPT ENGINE: JAVASCRIPT
JavaScript allows the developer to configure interceptors and
alter the values or references of particular properties in a script.

12. SCRIPT ENGINE: PYTHON
Python allows the developer to configure interceptors and alter the
values or references of particular properties in a script.

13. SCRIPT ENGINE: RUBY
Ruby allows the developer to configure interceptors and alter the values
or references of particular properties in a script.

14. POLYGLOT: DESIGN (DEMO)
Putting all available Scripting Languages in a row.

15. POLYGLOT: IMPLEMENTATION
<![CDATA[return "Groovyn"]]>
<![CDATA[message.payload = payload +
"JavaScriptn";
result = message;]]>
<![CDATA[result = payload + "Pythonn"]]>
<![CDATA[return $payload + "Rubyn"]]>

16. POLYGLOT: EXECUTION
Executing the configuration via a browser or REST
client:

17. SUMMARY
Mule allows developers to:
• Build their own component and/or transformer
• Simply write their favorite programming language
• Put the different programming languages in a row
