MuleSoft MuleSoft Meetup - Shared Flows
The document outlines a presentation agenda on code reusability with Mule Shared Flows. The agenda includes introductions, concepts of shared flows, pros and cons of reusable code, and a demo of implementing shared flows. Shared flows allow code to be reused across multiple Mule applications by creating reusable flows in Mule plugin projects that can then be added as dependencies to applications.

- 5. 5 What are Flows? Aflow is a pipeline of message processors. Flows consist of 3 parts: • Event Source • Process • Error Handling A private flow is a flow that can’t be accessed from outside the Mule app because it has no source defined. A subflow has no Event Source and no Error Handling scope. XML FILE MULE APPLICATION

Common Flows or Global Flows): ○ Flows that we can shared across multiple applications ○ Shared Flows are created in Mule Plugin projects ○ Mule Plugins can host many Shared Flows ○ Mule Plugins can be published in external repositories (Exchange, Jfrog, Nexus, etc) ○ Mule Plugins can be added as a library (dependency in POM file) What are Shared Flows?
