Anypoint Platform Development: Mule 4 for Mule 3 Users Training

Curriculum:

Module 1: Building Mule 4 Applications

• Use new features of Anypoint Studio 7 including the new Mule Palette, externalized connectors, and more
• Describe the structure of new Mule 4 projects and deployable archives
• Use the new Mule 4 event model to get and set data
• Enrich Mule messages directly in a connector instead of using the Mule 3 Message Enricher scope
• Write inline expressions using DataWeave 2 instead of MEL
• Configure flow performance by configuring max concurrency instead of thread pools in Mule 4

Module 2: Configuring Mule 4 Applications and Domains

• Create Mule 4 domains using Maven coordinates and use them to inherit all dependencies
• Create and use YAML configuration files to organize properties into hierarchical namespaces
• Add secure properties to Mule 4 applications

Module 3: Integrating with External Services using Mule 4

• Use one common, unified operations syntax to configure and use all Mule connectors
• Apply both read and write operations for JMS, Database, File, and FTP connectors anywhere in a flow
• Import and integrate with Java libraries
• Use repeatable and concurrent streams with File and FTP connectors
• Use dynamic and parameterized values together in a single database query

Module 4: Writing Defensive Code with Mule 4

• Build unit test suites for the new Mule 4 event model using MUnit 2
• Build simpler MUnit test conditions with MUnitTools
• Filter messages using Choice routers and private flows instead of Mule 3 Filters
• Use Validators to throw Mule 4 errors instead of Java exceptions
• Throw custom error types built from standard Mule 4 errors

Module 5: Handling Errors and Debugging in Mule 4

• Catch Mule 4 errors using the new Mule error handling framework
• Distinguish between the behavior of Mule 4 On Error Continue and On Error Propagate scopes
• Use the new Try scope to handle errors for one or more event processors instead of at the flow level
• Catch and handle custom Mule 4 error mappings

Module 6: Transforming Data with Mule 4

• Use new syntax and features of DataWeave 2 to write expressions and scripts
• Simplify and abstract DataWeave 2 code into reusable functions and modules
• Call static Java methods from DataWeave 2 expressions
• Call Java methods using the new Java module
• Pass in parameters to external scripts from a Mule 4 flow

Module 7: Connecting to and Processing Data Sources in Mule 4

• Use Mule 4 connector listeners to poll databases and file systems for changes
• Use Mule 4 connector operations to transform and write out data between files, databases, and an FTP server
• Use watermarks and object stores to avoid duplicate message processing
• Concurrently process a collection of data inside a flow using Mule 4 Batch scopes
