Enhancing Dynamics 365 Client API Interaction with Xrm-Ex

Stepping into software development for Dynamics 365, developers come across various tools and frameworks to make working with its Client API easier. Xrm-Ex stands out as a strong framework designed mainly for JavaScript, even though it has roots in TypeScript. The main goal of Xrm-Ex is to simplify how developers interact with the formContext and the Xrm Object. By doing this, it aims to reduce the amount of code developers have to write, making the codebase easier to manage and less likely to have errors.

Xrm-Ex provides a set of wrappers that work well with the Dynamics 365 Client API, making the developer experience smoother. With Xrm-Ex, developers have a toolkit that can help boost productivity, allowing more focus on creating great applications. This article will explore the Xrm-Ex framework, covering its installation, core features, how it can be used in real-world scenarios, and how developers can contribute to its community. All these aspects make Xrm-Ex a reliable choice for developers working with the Dynamics 365 Client API landscape.

Understanding Xrm-Ex

Xrm-Ex is a solid framework tailored for Dynamics 365 Client API. Although it's built with TypeScript principles, it's mainly made for JavaScript usage. The key goal of Xrm-Ex is to make working with the formContext and the Xrm Object simpler. By doing this, it aims to cut down the amount of code you need to write, ensuring your codebase remains easy to manage and less likely to have errors.

At its core, Xrm-Ex aims to streamline the interaction between developers and Dynamics 365. It does this by providing a clear structure and set of tools that help manage the different parts and events within Dynamics 365. This makes it easier to work with Dynamics 365's Client API, reducing the learning curve and making the development process more straightforward.

By using Xrm-Ex, developers can focus more on building out their applications' functionality rather than getting bogged down with managing complex interactions with Dynamics 365. This way, Xrm-Ex helps in maintaining a clean and efficient codebase, making the development process smoother and more enjoyable.

Video: Deployment

After installing Xrm-Ex, the next step is to set up your project. The setup involves adding XrmEx.js from your node_modules to your Dynamics 365 form as a library. Here’s a basic template to help you get started with your JavaScript setup:

/// <reference path="node_modules/xrm-ex/src/XrmEx.d.ts" />
var YourNamespace = YourNamespace || {};
YourNamespace.Contact = YourNamespace.Contact || {};
//Only properties assigned to the Self object will be exposed to the global scope
(function (Self) {
    class Fields {
        Firstname = new XrmEx.Class.TextField("firstname");
        Customer = new XrmEx.Class.LookupField("parentcustomerid");
        DoNotEmail = new XrmEx.Class.BooleanField("donotemail");
        Birthday = new XrmEx.Class.DateField("birthdate");
        PreferredContactMethod = new XrmEx.Class.OptionsetField(
            "preferredcontactmethodcode",
            {
                Any: 1,
                Email: 2,
                Phone: 3,
                Fax: 4,
                Mail: 5,
            }
        );
    }
    class Tabs {
        General = new XrmEx.Class.Tab("tab1", {
            Section1: new XrmEx.Class.Section("section1"),
            Section2: new XrmEx.Class.Section("section2"),
        });
        Details = new XrmEx.Class.Tab("tab2", {
            Section1: new XrmEx.Class.Section("section1"),
            Section2: new XrmEx.Class.Section("section2"),
        });
    }
    class Grids {
        ContactSubgrid = new XrmEx.Class.GridControl("Test");
    }
    /**@type {Fields}*/ var fields;
    /**@type {Tabs}*/ var tabs;
    /**@type {Grids}*/ var grids;

    /**
     * @param {Xrm.FormContext | Xrm.Events.EventContext} executionContext 
     */
    Self.OnLoad = async function OnLoad(executionContext) {
        await Init(executionContext); //Ensures XrmEx is only accessed after the OnLoad Event
        try {
            fields.Firstname.Value = "Joe";
            fields.PreferredContactMethod.Value = fields.PreferredContactMethod.Option.Phone;
            fields.Firstname.setVisible(true).setDisabled(true).setRequired(false);
            await XrmEx.openAlertDialog("Success", "Xrm works.");
        } catch (error) {
            console.error(error);
            await XrmEx.openAlertDialog("Error", `Error in ${XrmEx.getFunctionName()}\n` + error.message);
        }
    };
    /**
     * @param {Xrm.FormContext | Xrm.Events.EventContext} executionContext 
     */
    async function Init(executionContext) {
        if (!XrmEx) {
            let errorMessage = "XrmEx is not loaded. Please make sure you have XrmEx.js loaded in your form.";
            console.error(errorMessage);
            await Xrm.Navigation.openAlertDialog({ title: "Error", text: errorMessage, });
            return;
        }
        XrmEx.Form.formContext = executionContext;
        fields = new Fields();
        tabs = new Tabs();
        grids = new Grids();
        parent.window.XrmEx = XrmEx;
    }

})(YourNamespace.Contact);

In the code above, you create a namespace for your code to live in and then wrap your code in a function to keep it organized and prevent global scope pollution.

To deploy, follow the instructions provided in the video: Xrm-Ex Deployment. This is a detailed guide on how to deploy your project.

Now, you'll want to add XrmEx.js from your node_modules to your Dynamics 365 form as a library. Then, execute the method YourNamespace.ContactFunctions.OnLoad in your form and pass the executionContext to that function

And that's it! You've now installed Xrm-Ex, set up your project, and deployed it to Dynamics 365. You're ready to start coding and enjoying a simplified interaction with the formContext and the Xrm Object.
