Polyglot Mule Transformers
Download as PPTX, PDF0 likes414 views
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.

Polyglot Mule Transformers
- 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 [ This topic is discussed in different presentation ]
- 6. .NET [ This topic is discussed in different presentation ]
- 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
