Azure Communication Email client library for JavaScript

This package contains a JavaScript/TypeScript SDK for Azure Communication Services for Email.

Getting started

Prerequisites

You need an Azure subscription, a Communication Service Resource, and an Email Communication Resource with an active Domain.

To create these resource, you can use the Azure Portal, the Azure PowerShell, or the .NET management client library.

Installing

1npm install @azure/communication-email

Examples

EmailClient provides the functionality to send email messages.

Authentication

Email clients can be authenticated using the connection string acquired from an Azure Communication Resource in the Azure Portal.

1const { EmailClient } = require("@azure/communication-email");
2
3const connectionString = `endpoint=https://<resource-name>.communication.azure.com/;accessKey=<Base64-Encoded-Key>`;
4const client = new EmailClient(connectionString);

You can also authenticate with Azure Active Directory using the Azure Identity library. To use the DefaultAzureCredential provider shown below, or other credential providers provided with the Azure SDK, please install the @azure/identity package:

1npm install @azure/identity

The @azure/identity package provides a variety of credential types that your application can use to do this. The README for @azure/identity provides more details and samples to get you started. AZURE_CLIENT_SECRET, AZURE_CLIENT_ID and AZURE_TENANT_ID environment variables are needed to create a DefaultAzureCredential object.

1import { DefaultAzureCredential } from "@azure/identity";
2import { EmailClient } from "@azure/communication-email";
3
4const endpoint = "https://<resource-name>.communication.azure.com";
5let credential = new DefaultAzureCredential();
6const client = new EmailClient(endpoint, credential);

Send an Email Message

To send an email message, call the beginSend function from the EmailClient. This will return a poller. You can use this poller to check on the status of the operation and retrieve the result once it's finished.

1const message = {
2  senderAddress: "sender@contoso.com",
3  content: {
4    subject: "This is the subject",
5    plainText: "This is the body",
6  },
7  recipients: {
8    to: [
9      {
10        address: "customer@domain.com",
11        displayName: "Customer Name",
12      },
13    ],
14  },
15};
16
17const poller = await emailClient.beginSend(message);
18const response = await poller.pollUntilDone();

Send an Email Message to Multiple Recipients

To send an email message to multiple recipients, add a object for each recipient type and an object for each recipient.

1const message = {
2  senderAddress: "sender@contoso.com",
3  content: {
4    subject: "This is the subject",
5    plainText: "This is the body",
6  },
7  recipients: {
8    to: [
9      {
10        address: "customer1@domain.com",
11        displayName: "Customer Name 1",
12      },
13      {
14        address: "customer2@domain.com",
15        displayName: "Customer Name 2",
16      },
17    ],
18    cc: [
19      {
20        address: "ccCustomer1@domain.com",
21        displayName: " CC Customer 1",
22      },
23      {
24        address: "ccCustomer2@domain.com",
25        displayName: "CC Customer 2",
26      },
27    ],
28    bcc: [
29      {
30        address: "bccCustomer1@domain.com",
31        displayName: " BCC Customer 1",
32      },
33      {
34        address: "bccCustomer2@domain.com",
35        displayName: "BCC Customer 2",
36      },
37    ],
38  },
39};
40
41const poller = await emailClient.beginSend(message);
42const response = await poller.pollUntilDone();

Send Email with Attachments

Azure Communication Services support sending email with attachments.

1const filePath = "C://readme.txt";
2
3const message = {
4  senderAddress: "sender@contoso.com",
5  content: {
6    subject: "This is the subject",
7    plainText: "This is the body",
8  },
9  recipients: {
10    to: [
11      {
12        address: "customer@domain.com",
13        displayName: "Customer Name",
14      },
15    ],
16  },
17  attachments: [
18    {
19      name: path.basename(filePath),
20      contentType: "text/plain",
21      contentInBase64: readFileSync(filePath, "base64"),
22    },
23  ],
24};
25
26const poller = await emailClient.beginSend(message);
27const response = await poller.pollUntilDone();
