  Description
  This book is aimed to teach the readers how to design RAML APIs using Anypoint Platform. It also focuses on popular topics such as System Integration, API Led Connectivity, and Centre for Enablement and RAML. It will show how to use, call and test free mock REST APIs. The readers can also work with some commercially available license-based APIs. Furthermore, the book will explain most of the examples provided by RAML.org so that you can simulate it from your local system. This book will then help you develop your RESTful API specification for adding, retrieving, updating and deleting data for a business entity. Later, you will learn how to use the MuleSoft Anypoint Platform Designer for designing and simulating your RAML API design specifications. By the end, you will be able to develop an end to end RAML API using the MuleSoft Anypoint Studio. What you will learn
  
• Get exposed to Payload handling, logging and variables
• Work with different Flow Control components such as Choice, First Successful, Round-Robin and Scatter Gather
• Explore and work with Error Handling components such as Error Handler, On Error, Continue, On Error Propagate and Raise Error
• Understand Global Configuration Properties and Securing properties
• Gain knowledge about various scopes involved in MuleSoft Flow designing
• 
  Who this book is for
  This book is meant for anyone interested to become an API designer. Experienced technical persons of the IT industry also can utilize the book to get extra insights, and they can align their knowledge in line with it. Table of Contents

CHAPTER 1

Start Project

Introduction

MuleSoft Anypoint Studio is an Integrated Development Environment where you can develop your Mule Flows, Test, and Deploy. Volume 2 is focusing on the topics like features of Anypoint Studio, how to develop mule flows, the various components of Anypoint Studio, and so on.

In this chapter, we will discuss the following topics:

• Volume 1: quick revisit
• How to approach each volume?
• Anypoint Studio
  • Basics
  • Key facilities
  • Help features
• Project creation
  • Mule project
  • Domain project
  • Mule modules
  • Open template
  • Exchange examples
  • Import project

Objectives

After studying this chapter, you should be able to understand:

• Anypoint Studio
• Anypoint Studio important features
• Project creation scenarios in Anypoint Studio
• Mule modules
• Global configurations

About target audience

Anybody who is willing to become a MuleSoft API Designer or MuleSoft Developer can read this book to gain knowledge about Anypoint Studio. No prior knowledge like programming skills or specific domain-based exposure required for grasping the concepts are explained in this book. The audience can simply follow the steps given in this book to achieve the desired result. As we are keeping all types of audiences like freshers and non-programmers in mind while designing this book, we are making sure that after reading this book, the audience can handle the features of Anypoint Studio and even future releases like a pro. We have provided numerous screenshots that are taken after executing in a proper environment and provided the sample code of the same for the readers’ better understanding of how the input configurations and output of each MuleSoft flow will look like. On the other hand, we are keeping the non-programming Business Experts and top-level management people in mind, so that the examples and procedures given in this book can be read by them thoroughly without bothering about practicing them in a system. In this way, even the non-programmers and developers can understand the internals of the development environment of a typical MuleSoft platform.

Prerequisites

• Anypoint Studio Installation
• http://anypoint.mulesoft.com/ exposure and registration
• REST API basics
• Basic HTTP request-response knowledge
• Web service clients like Postman
• Basic HTTP web service methods, inputs, and outputs

About mastering MuleSoft volume 1

The Volume 1 of Mastering MuleSoft deals with API led connectivity paradigm and API design lifecycle. It also talks about the various roles like API designer, API developer, API manager, API administrator, and so on. Volume 1 mainly focuses on the API designer activities like developing specifications for an API using the Restful API Markup Language (RAML).

The API designer’s role is to define, implement, and document the specifications of a web service API that may be a REST or SOAP-based web service. Also, before sharing these API specifications to API developers, API testers, API administrators, and so on the API designers must be able to simulate the design specifications like GET and POST web services endpoints, the input examples for those endpoints, the expected output results from those endpoints by using a mock service provided by any point platform. A typical web service will be having endpoint resources like GET, POST, PUT, DELETE, and so on. These methods are used for creation, retrieval, update, and deletion of a business entity or object like an employee, passengers, and so on.

Using RAML specifications, the API designers can create API specifications that will have instructions about how the web services endpoints will be developed by the developers for operations like create, retrieve, update, and delete a particular business entity. Apart from the basic CRUD operations, the API specifications will include operational and transactional web services as well.

The previous volume also talks about integrating the API specifications through Anypoint Studio and APIKit via Anypoint Exchange and how the developers can implement their code to the shared API specifications. The APIKit will have an API console using which the developed APIs can be tested. The APIKit will act as a gatekeeper for preserving the API specifications to avoid any tampering of the specifications at the developer or tester end.

The dummy REST APIs available for testing over the internet were explored and the real-time commercial REST APIs also have been utilized and tested. The examples provided by RAML organizations have been executed and the quick steps for reusing the RAML code snippets have been covered.

Finally, in the last volume, we have developed a complete RAML specification by reusing the existing examples and have implemented the RAML concepts like Traits, Resources, Examples, and so on. The completed project has been imported to Anypoint Studio and Implemented and tested using API Tool Kit.

How to approach the volumes?

The idea of separating the whole content into different volumes like API design, Anypoint Studio, Connectors, Transformations, and Cloudhub is to make things easy for you, and you can choose which area you want to focus on if you don’t like to look into the entire scope of MuleSoft ecosystem, at the same time it is mandatory for the API designers and API developers to follow the entire volumes in a sequential order to gain practical experience and become hands-on with all areas of MuleSoft ecosystem.

Also, the volumes are designed in a way that anybody from the Industry can try to read these volumes even if they are not going to develop API specifications or implement API specifications, for example, somebody from the HR department or a college Head of Department. Only by going through the screenshots and sample code snippets, they must have a fair idea about how the MuleSoft development and implementation are happening.

This book is aiming for students, freshers, and budding developers to explore more connectors and techniques that may not be discussed in this series elaborately, but still, this book guides them to explore the MuleSoft techniques so that if they learn and implement all concepts from this book, then definitely they will be able to search and implement more topics of MuleSoft by themself.

Only the Transformation volume will be a bit programmatical, but still it will be elaborating new programming and scripting tech...
