Mule ESB is the heart of applications that require routing and improvement of messages such as electronic invoicing.
Mule ESB combines Mule Expression Language and DataWeave to facilitate data transformation and orchestration. Its event-based architecture, extensive connectors, and API management capabilities ensure seamless integration, enhancing microservice architectures. Although the documentation is often cryptic and upgrades are troublesome, frequent patches aim to mitigate stability and scalability issues. The lack of BPM support and dependency on Maven are drawbacks. Offering more sample codes could improve the user experience.
