Mule 4


                                  Mule 4 


Mule 4 is the latest version of MuleSoft’s integration platform, and it comes with significant improvements and enhancements over its predecessor, Mule 3. Mule 4 is designed to provide more power, flexibility, and ease of use when building integration applications and APIs. Here are some key features and highlights of Mule 4:

  1. DataWeave 2.0:

    • Mule 4 introduces DataWeave 2.0, a powerful transformation language that allows developers to easily map and transform data between different formats and structures. DataWeave 2.0 offers advanced capabilities for data manipulation and is integrated into Mule 4’s core.
  2. Streaming and Lazy Loading:

    • Mule 4 offers improved handling of large data sets through streaming and lazy loading. This allows for efficient processing of large files and payloads without loading the entire content into memory.
  3. Improved Error Handling:

    • Error handling in Mule 4 has been enhanced with the introduction of Try scope and error handling policies. This makes it easier to handle errors and exceptions within integration flows.
  4. Simplified Flows:

    • Mule 4 introduces a simplified and more intuitive way to design integration flows. Developers can create flows more easily with less configuration and boilerplate code.
  5. Flow Reference:

    • The new Flow Reference component allows for the modularization and reuse of integration flows within an application, promoting better code organization and maintainability.
  6. API Auto-Discovery:

    • Mule 4 includes an API auto-discovery feature that simplifies the process of exposing APIs from a RAML or OpenAPI Specification (formerly known as Swagger) file. It automatically generates the necessary flows and configuration.
  7. APIKit for SOAP:

    • APIKit for SOAP simplifies the creation of SOAP-based APIs in Mule 4, providing a visual design experience for defining SOAP APIs.
  8. Enhanced Connectors:

    • Mule 4 offers improved connectors that are more user-friendly and provide better out-of-the-box capabilities for integrating with various systems and services.
  9. Non-blocking HTTP Listener:

    • The HTTP Listener in Mule 4 is non-blocking by default, which improves concurrency and allows for better handling of high traffic loads.
  10. Enhanced Anypoint Studio:

    • Anypoint Studio, the integrated development environment for Mule 4, comes with a refreshed and more user-friendly interface, making it easier to design, develop, and test integration applications.
  11. Enhanced Monitoring and Analytics:

    • Mule 4 provides enhanced monitoring and analytics capabilities through Anypoint Monitoring, allowing users to gain insights into application performance, errors, and trends.
  12. Support for CloudHub and Hybrid Deployment:

    • Mule 4 fully supports CloudHub, MuleSoft’s cloud-based integration platform as a service (iPaaS). It also allows for hybrid deployment options, enabling organizations to deploy integration applications on-premises, in the cloud, or in hybrid environments.
  13. Security Enhancements:

    • Mule 4 includes improvements in security features and provides better support for security policies, encryption, and authentication mechanisms.
