Microsoft Dynamics 365 Extensions Cookbook

Overview of this book

Microsoft Dynamics 365 is a powerful tool. It has many unique features that empower organisations to bridge common business challenges and technology pitfalls that would usually hinder the adoption of a CRM solution. This book sets out to enable you to harness the power of Dynamics 365 and cater to your unique circumstances. We start this book with a no-code configuration chapter and explain the schema, fields, and forms modeling techniques. We then move on to server-side and client-side custom code extensions. Next, you will see how best to integrate Dynamics 365 in a DevOps pipeline to package and deploy your extensions to the various SDLC environments. This book also covers modern libraries and integration patterns that can be used with Dynamics 365 (Angular, 3 tiers, and many others). Finally, we end by highlighting some of the powerful extensions available. Throughout we explain a range of design patterns and techniques that can be used to enhance your code quality; the aim is that you will learn to write enterprise-scale quality code.

Preface

Client-side concurrency control


As described in the previous recipe, sever-side concurrency control can be enabled when making a server-side UpdateRequest or DeleteRequest, however, client-side concurrency is not currently available while using the frontend UI.

In this recipe, we will create a custom JavaScript library that checks for concurrency when saving the record, essentially enabling a client-side optimistic concurrency control mechanism. We will then enable it for the contact entity being used.

Getting ready

In order to build this customization, you will require the System Customizer or higher security role. End users, however, will only require read/create/update access to the entities.
