Migrating a MuleSoft Connector from Mule 3 to Mule 4

In this article, we will explain (step-by-step) how to migrate a MuleSoft connector from Mule 3 to Mule 4 using the Devkit Migration Tool (DMT).

Using your Java code in Mule4

In this post, we take a look at different methods of integrating your Java code in the latest version of Mule.

Accelerate Your Digital Journey with Mule 4 and C4E

MuleSoft has recently announced a crowd release of Mule 4.0 - the latest iteration of the Mule runtime engine. Mule 4 innovatively delivers a vastly more powerful all-purpose engine for building application networks, while retaining everything users of Mule 3 loved - its lightweight, runtime, and extensibility.

Dataweave allows programmers to use the operations groupBy, orderBy and distinctBy when defining their scripts. groupBy is often used with some function to group objects by certain keys. orderBy is often used with some function to order objects by certain keys. distinctBy is often used with the anonymous parameter $ to eliminate duplicate objects. In this blog post we shall focus on how these functions behave when they are given ...read more »

Mule offers three main processing strategies; Synchronous, Queued Asynchronous and Non-Blocking (introduced in Mule 3.7). Before Mule 3.7 any flow that started with an inbound endpoint that had the exchange pattern set to request-response had its processing strategy set to Synchronous. As shown in the diagram below, the Synchronous Processing Strategy implies that the same thread (the thread taken from the connector of the inbound endpoint) is used for the ...read more »

Introduction Dataweave allows programmers to use the reduce operation in their scripts. In fact there are two different kinds of reduce operation, depending on whether the accumulator of the operation is initialised or is left uninitialised. This operation can also be challenging to use unless one first masters its subtleties. In this blog post we shall: Explain how reduce with an initialised accumulator and an uninitialised accumulator works What results ...read more »

This blog post outlines how to use Dataweave to easily mock database connectors in MUnit, enabling test driven development for database based system APIs. Test driven development (TDD) is a development approach whereby tests for an application are defined and written before any code has been implemented, requiring the developer to thoroughly think through the expected behaviour beforehand and therefore reducing rework. In order to write tests for database system ...read more »
