Designing and Building Mule Applications

It's just as important that you follow the right approach to integration, as well as using the right technology. We'll start this session by exploring MuleSoft's API-led approach to connectivity, and then use demos to bring to life the tooling in Anypoint Platform that allows you to design and build your integration applications quickly

and easily.Brett Roeder - Principal Client Architect - Office of the CTO, Americas

As of April 20th, 2017 and subject to change at MuleSoft's exclusive discretion.

2. API Design

13

• Define a Canonical API (Customer)• RAML

–Reusing RAML Fragments• Libraries: Address, Phone, email, …•Traits

• API Console• Mock Service



RESTful API Modeling Language

• Open standard• Clean, clear, powerful• 100% natural & organic• Open, vendor-neutral• Practical• Pattern-based design• JSON/XML with one RAML

Write once. Use many. Creative laziness

14



API Designed with CURRENT API Designer

15

• Can– leverage RAML 1.0– define APIs to

support XML & JSON from one spec

• Cannot– publish

fragments/specs to Exchange

– search for fragments



API Designed with NEW API Designer

16

• Can– leverage RAML 1.0– define APIs to

Consume Fragments from Exchange

17



Publish API Specs & Fragments to Exchange

18

• New version automaticallycreated

• Add tags

• Publish to API Manager

•Implement the Customer MySQL System API•Implement the Customer Process API•Test the API with MUnit•Deploy the API•Auto register your API



Implementing a System API

SystemAPIs

• No system talks directly to any other system

• API defined using your terminology

• Embedded governance & security

• Minimizes disruption caused by new releases

• Generate a Test Suite

Test an API

With MUnit you can:● Create your Mule test by writing Mule code● Create your Mule test by writing Java code● Disable flow inbound endpoints● Disable endpoint connectors● Mock outbound endpoints● Mock message processors● Spy any message processor● Verify message processor calls● Create not only unit tests but also integration tests in a local

environment — MUnit allows you to start a local FTP/SFTP or DB server● Call the Mule client from Mule code● Assert flow exceptions● Enable or disable particular tests● See assertion/error reports with Mule stack trace● Extend the MUnit framework with plugins● Check visual coverage in Studio● Debug your tests with Studio

Extending Mule• Extending Components

– Transformers, filters, routers, ...

• Custom Message Processors• Creating Example Archetypes• Creating a Custom XML Namespace• Creating Module Archetypes• Creating Catalog Archetypes• Creating Project Archetypes• Creating Transports• Creating Custom Routers

DevKit (Custom Connectors)● Visual design and implementation using

Anypoint Studio with an Eclipse-based interface that simplifies and speeds up development.

● Maven support.● Connector packaging tools.● Authentication support for multiple types of

authentication, including OAuth and username and password authentication.

● DataSense support to acquire remote metadata.

● Extensive testing capability.● Examples, training, and support to simplify

development startup.● Batch, Query Pagination, and DataSense Query

Language support.
