Breaking Changes in v2

[AleksandrRogov]

This issue is for adding Breaking Changes that have been done in v2.
The list is not complete and will be updated. Once it is complete, it will be merged with DynamicsWebApi documentation.

1. DynamicsWebApi Callbacks is fully removed

All modern browsers support Promises (including await/async). Furthermore, the main reason why the Callbacks version was added in the first place was Internet Explorer which has been replaced with Edge and is neither maintained or supported by Microsoft anymore.

2. Configuration object changes

webApiUrl and webApiVersion have been removed and replaced with serverUrl, dataApi and searchApi. #139

Node.JS
Before

new DynamicsWebApi({
    webApiUrl: "https://<YOUR ORG HERE>.api.crm.dynamics.com/api/data/v9.1/"
});

Now

new DynamicsWebApi({
    serverUrl: "https://<YOUR ORG HERE>.api.crm.dynamics.com",
    dataApi: {
        version: "9.1"
    }
});

Web Resource
Before

new DynamicsWebApi({
    webApiVersion: "9.1"
});

Now

new DynamicsWebApi({
    dataApi: {
        version: "9.1"
    }
});

3. All request functions with multiple parameters are removed.

No more "simple" functions with multiple parameters. This has been done to streamline the request parameters and not introduce breaking changes when new parameters have been added. Furthermore, now all functions have access to impersonation, cache and data tracking functionality.

4. Changes to the names of some request functions and properties

Old Name	New Name
createRequest	create
updateRequest	update
upsertRequest	upsert
deleteRequest	deleteRecord
retrieveRequest	retrieve
retrieveMultipleRequest	retrieveMultiple
retrieveAllRequest	retrieveAll
executeFetchXml	fetch
executeFetchXmlAll	fetchAll
executeBoundFunction	callFunction
executeUnboundFunction	callFunction
executeBoundAction	callAction
executeUnboundAction	callAction
utility	Utility

5. In some requests entity property is replaced with data

Affected requests: createRequest, updateRequest and upsertRequest and their corresponding new names: create, update and upsert.

Example:

const lead = {
    subject: "Test WebAPI",
    firstname: "Test",
    lastname: "WebAPI",
    jobtitle: "Title"
};

const result = await dynamicsWebApi.create({
    collection: "leads",
    data: lead,
    returnRepresentation: true
});

6. config.onTokenRefresh is now a promise-based function

Usage example:

const cca = new MSAL.ConfidentialClientApplication(msalConfig);
const serverUrl = 'https://<YOUR ORG HERE>.api.crm.dynamics.com';

//function calls an external functionality that acquires a token and passes it to DynamicsWebApi
const acquireToken = async () => {
    try {
        return await cca.acquireTokenByClientCredential({
            scopes: [`${serverUrl}/.default`],
        });
    }
    catch (error) {
        //error logging here
        //or a fallback authentication

        //to abort a request just return null
        //or re-throw an error
        return null;
    }
}

const dynamicsWebApi = new DynamicsWebApi({
    serverUrl: serverUrl,
    onTokenRefresh: acquireToken
});

7. Removed id property from the request object.

id has been deprecated for quite some time and got removed in v2. Use key instead.

8. Default version of Dataverse API is set to 9.2

In case you still need version 8.0, please set dataApi.version to 8.0.

9. Supported minimum version of Node.js raised to v.15.0.0.

It was time to finally bump up the JavaScript specification from ES5 to ES2020 for the project. It is widely supported in all modern browsers and all currently maintained versions of Node. Even though the minimum Node.js version that supports ES2020 is 14.5.0, I would recommend running DynamicsWebApi on at least v.15.0.0 for all features to work correctly. In all versions prior to 15 the AbortSignal functionality won't work because it did not exist there yet.
