Dataverse Client for Node.JS

dataverse-client is library for Node.JS to make WebAPI requests to Dataverse and Dynamics 365 CE (on-premises).

dataverse-client provides a Query builder to build OData queries.

Works with a token provider. Use @primno/dataverse-auth to authenticate with a Connection String or OAuth2.

This package is part of the Primno framework.

Compatibility

dataverse-client works with Dataverse (Dynamics 365 Online) and Dynamics 365 CE (on-premises).

Quick start

Installation

  npm install @primno/dataverse-client @primno/dataverse-auth

Usage

With a connection string:

import { DataverseClient } from '@primno/dataverse-client';
import { ConnStringTokenProvider } from '@primno/dataverse-auth';

const tokenProvider = new ConnStringTokenProvider(
    "AuthType=OAuth;Url=https://<Environnement>.crm.dynamics.com;UserName=<UserName>;TokenCacheStorePath=./.cache/token.json",
    {
        oAuth: {
            // For device code flow
            deviceCodeCallback: (deviceCode) => {
                console.log(deviceCode.message);
            }
        }
     }
);

const client = new DataverseClient(tokenProvider);

const accounts = await client.retrieveMultipleRecords("accounts", { top: 10 });
console.log(accounts);

With OAuth:

import { DataverseClient } from '@primno/dataverse-client';
import { OAuthTokenProvider } from '@primno/dataverse-auth';

const tokenProvider = new OAuthTokenProvider({
    url: "https://<Environment>.crm.dynamics.com",
    credentials: {
        clientId: "51f81489-12ee-4a9e-aaae-a2591f45987d", // Sample client id
        redirectUri: "app://58145B91-0C36-4500-8554-080854F2AC97", // Sample redirect uri
        authorityUrl: "https://login.microsoftonline.com/common",
        scope: "https://<Environment>.crm.dynamics.com/.default",
        grantType: "device_code",
        userName: "<Username>"
    },
    persistence: {
        enabled: false
    },
    deviceCodeCallback: (deviceCode) => {
        console.log(deviceCode.message);
    }
});

const client = new DataverseClient(tokenProvider);

const accounts = await client.retrieveMultipleRecords("accounts", { top: 10 });
console.log(accounts);

Authentication

@primno/dataverse-client needs a token provider to authenticate with Dataverse. Use @primno/dataverse-auth to authenticate with a Connection String or OAuth2.

You can also use your own token provider by implementing the TokenProvider interface.

To learn more about available authentication methods, see the @primno/dataverse-auth documentation.

Queries

The following methods are available to query Dataverse:

• retrieveMultipleRecords: Retrieves a set of records.
• retrieveRecord: Retrieves a single record by its id.
• createRecord: Creates a record.
• updateRecord: Updates a record by its id.
• deleteRecord: Deletes a record by its id.
• executeAction: Executes an action.

Retrieve can be done by providing a RetrieveMultipleOptions object or a raw query string.

Note: The name of the entity must be the entity set name (plural).

Examples

1. Retrieves first 10 accounts.

   interface Account {
       name: string;
       emailaddress1: string;
   }
   
   const accounts = await client.retrieveMultipleRecords<Account>(
       "accounts",
       {
           top: 10,
           select: ["name", "emailaddress1"],
           orders: [{ attribute: "name", order: "asc" }]
       }
   );

2. Create a contact.

   const contact = await client.createRecord("contacts", {
       firstname: "Sophie", lastname: "Germain"
   });

3. Delete a account.

   await client.deleteRecord("accounts", "00000000-0000-0000-0000-000000000000");

4. Retrieves a contact by its id.

   const contact = await client.retrieveRecord("contacts", "00000000-0000-0000-0000-000000000000", { select: ["firstname"] });

5. Retrieves actives opportunities using a custom query option string.

   const opportunities = await d365Client.retrieveMultipleRecords("opportunities", "?$select=name,$filter=state eq 0");

6. Retrieves all contacts using OData pagination. The page size is set to 50. The nextLink attribute is used to get the next page.

   const contacts = []; // Will contain all contacts.
   
   let options: RetrieveMultipleOptions | undefined = {
       select: ["firstname", "lastname"]
   };
   
   let result: EntityCollection;
   
   do {
       result = await client.retrieveMultipleRecords("contacts", options, 50 /* Page Size = 50 */);
       contacts.push(...result.entities);
       options = result.nextLink;
   } while(result.nextLink);
   
   console.log(contacts);

7. Retrieves contacts created this month.

   const contacts = await client.retrieveMultipleRecords("accounts", {
       select: ["name"],
       filters: [{ conditions: [{ attribute: "createdon", operator: "ThisMonth" }] }]
   });

Troubleshooting

Unable to verify the first certificate

On on-premises environments, you may have this error :

Error: unable to verify the first certificate

To fix this issue, you can add your enterprise CA certificate to the trusted root certificate authorities by setting the NODE_EXTRA_CA_CERTS environment variable. See Node.js documentation for more information.
