How to integrate v0 with OneDrive?

Step 1: Adding the MSAL Dependency via Code

Since v0 does not have a terminal, you need to include the MSAL (Microsoft Authentication Library) by adding a script tag in your main HTML file (usually index.html).
Locate your project’s index.html file and insert the following script tag inside the <head> section to load MSAL from a CDN:


<script src="https://alcdn.msauth.net/browser/2.16.1/js/msal-browser.min.js"></script>

Step 2: Creating the OneDrive Authentication File

Create a new TypeScript file named onedriveAuth.ts in your project's source folder (for example, in the src directory).
This file contains the configuration and helper function to authenticate the user with OneDrive using MSAL.
Insert the following code in onedriveAuth.ts:


/ onedriveAuth.ts /
interface MsalConfig {
  auth: {
    clientId: string;
    authority?: string;
    redirectUri?: string;
  };
}

const msalConfig: MsalConfig = {
  auth: {
    // Replace with your own Application (client) ID from the Azure portal.
    clientId: "YOURCLIENTID_HERE",
    // Authority URL (optional): "https://login.microsoftonline.com/common"
    authority: "https://login.microsoftonline.com/common",
    // The redirect URI configured in your Azure app registration.
    redirectUri: window.location.origin,
  }
};
// Initialize MSAL upon script load.
const msalClient = new msal.PublicClientApplication(msalConfig);
export async function signIn(): Promise<any> {
  try {
    const loginResponse = await msalClient.loginPopup({
      scopes: ["user.read", "files.readwrite.all"]
    });
    return loginResponse;
  } catch (error) {
    console.error("Login Error:", error);
    throw error;
  }
}

Step 3: Creating the OneDrive Service File

Create another TypeScript file named onedriveService.ts (for example, in the src directory).
This file will contain functions to interact with the OneDrive API using Microsoft Graph.
Add the following code to onedriveService.ts:


/ onedriveService.ts /
import { signIn } from "./onedriveAuth";

export async function listOneDriveFiles(): Promise<any> {
  try {
    // Sign in (or ensure the user is signed in) to obtain an access token.
    const authResponse = await signIn();
    // Use the acquired access token to call the Microsoft Graph API.
    const accessToken = authResponse.accessToken;
    const response = await fetch("https://graph.microsoft.com/v1.0/me/drive/root/children", {
      headers: {
        "Authorization": Bearer ${accessToken}
      }
    });
    if (!response.ok) {
      throw new Error("Error fetching OneDrive files");
    }
    const data = await response.json();
    return data;
  } catch (error) {
    console.error("OneDrive API Error:", error);
    throw error;
  }
}

Step 4: Integrating OneDrive Service into Your Main Code

Locate your main application file (for example, app.ts or main.ts).
Import the OneDrive service function and add code to call it when needed (for example, when a user clicks a button to list files).
Insert the following code snippet in your main file where it fits best (for example, after other imports and within an event handler):


/ app.ts or main.ts /
import { listOneDriveFiles } from "./onedriveService";

// Example function that triggers the OneDrive API call
async function showOneDriveFiles() {
  try {
    const files = await listOneDriveFiles();
    console.log("Fetched OneDrive Files:", files);
    // You can add additional code here to display the files on your webpage.
  } catch (error) {
    console.error("Error displaying OneDrive files:", error);
  }
}
// Example: call showOneDriveFiles when a button is clicked
const listButton = document.getElementById("list-files-btn");
if (listButton) {
  listButton.addEventListener("click", showOneDriveFiles);
}

Step 5: Updating Your HTML to Add a Trigger Element

If you do not already have a button or trigger in your HTML, open your index.html file.
Add a button element to allow users to initiate the OneDrive file listing:


<!-- index.html -->
<button id="list-files-btn">List OneDrive Files</button>

Step 6: Finalizing and Testing the Integration

After inserting all the above code snippets in their respective files, save all changes.
Run your v0 project so that when a user clicks the "List OneDrive Files" button, the Microsoft authentication popup appears and, after a successful sign-in, the files from the OneDrive root are fetched via the Microsoft Graph API.
Check the browser console to view the logged output or errors for debugging if necessary.
