Frontend JavaScript for Email Sending Interface with Microsoft Graph

Making Graph API Requests and Authentication with MSAL.js

// JavaScript Frontend Script for Sending Email with Attachment
const clientId = "YOUR_CLIENT_ID";
const authority = "https://login.microsoftonline.com/YOUR_TENANT_ID";
const clientSecret = "YOUR_CLIENT_SECRET"; // Use only in a secure environment
const scopes = ["https://graph.microsoft.com/.default"];

const msalConfig = {
    auth: {
        clientId: clientId,
        authority: authority,
    }
};

const myMSALObj = new Msal.UserAgentApplication(msalConfig);

async function signIn() {
    try {
        const loginResponse = await myMSALObj.loginPopup({ scopes: scopes });
        console.log("id_token acquired at: " + new Date().toString());
        if (myMSALObj.getAccount()) {
            console.log("Now you can use the Graph API");
        }
    } catch (error) {
        console.log(error);
    }
}

async function sendEmail() {
    // Call the Graph API to send an email here
}
