How to integrate v0 with Garmin Connect?

Adding the Axios Dependency in Your Code

Since your v0 project does not have a terminal, you need to add the Axios library manually. Open your main HTML file (for example, index.html) and add the following script tag inside the <head> section:


<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>

This script tag loads Axios from a CDN, making it available for your TypeScript code.

Creating a New File for Garmin Connect Integration

Create a new file in your project directory and name it garminConnectIntegration.ts.
This file will contain the TypeScript code to integrate with Garmin Connect using OAuth 2.0.

Writing the Garmin Connect Integration Class

Open the newly created garminConnectIntegration.ts file and add the following code. This code defines a GarminConnect class that can generate an authorization URL and exchange an authorization code for an access token.


export class GarminConnect {
  private clientId: string;
  private clientSecret: string;
  private redirectUri: string;
  private baseUrl: string;

  constructor(clientId: string, clientSecret: string, redirectUri: string) {
    this.clientId = clientId;
    this.clientSecret = clientSecret;
    this.redirectUri = redirectUri;
    // Update this URL if Garmin Connect uses a different endpoint for OAuth
    this.baseUrl = 'https://connect.garmin.com';
  }
  public getAuthorizationUrl(): string {
    const url = ${this.baseUrl}/oauth/authorize?client_id=${this.clientId}&redirect_uri=${encodeURIComponent(this.redirectUri)}&response_type=code;
    return url;
  }
  public async getAccessToken(code: string): Promise {
    const url = ${this.baseUrl}/oauth/token;
    const body = {
      client_id: this.clientId,
      client_secret: this.clientSecret,
      code,
      redirect_uri: this.redirectUri,
      granttype: 'authorizationcode'
    };
    // Using Axios from the CDN loaded earlier
    const response = await (window as any).axios.post(url, body);
    return response.data.access_token;
  }
}

This class contains two main methods:
- getAuthorizationUrl: Builds the URL where users will be sent to authorize your application.
- getAccessToken: Exchanges a received authorization code for an access token using an HTTP POST request.

Integrating Garmin Connect in Your Main Code

In the main part of your application, you should now import and use the GarminConnect class. Open the file where you want to initiate the Garmin Connect authorization (for example, in app.ts or similar).
Add the following code snippet to import and use the integration:


import { GarminConnect } from './garminConnectIntegration';

// Replace these values with your actual Garmin Connect credentials and redirect URI.
const garmin = new GarminConnect('YOURCLIENTID', 'YOURCLIENTSECRET', 'YOURREDIRECTURI');
function initiateGarminAuth() {
  const authUrl = garmin.getAuthorizationUrl();
  // Redirect the user to Garmin Connect authorization page
  window.location.href = authUrl;
}
// Example: attach to a button click event
const authButton = document.getElementById('garminAuthButton');
if (authButton) {
  authButton.addEventListener('click', initiateGarminAuth);
}

This snippet creates an instance of the GarminConnect class using your Garmin credentials, defines a function to start the authorization process, and binds it to a button with the id garminAuthButton.

Handling the Redirect and Obtaining the Access Token

After the user authorizes your application, Garmin Connect will redirect back to the URL you provided (YOURREDIRECTURI) with a query parameter code.
Create or open a file (for example, authCallback.ts) that will handle this redirect. Add the following code to extract the authorization code from the URL and request an access token:


import { GarminConnect } from './garminConnectIntegration';

const garmin = new GarminConnect('YOURCLIENTID', 'YOURCLIENTSECRET', 'YOURREDIRECTURI');
async function handleAuthCallback() {
  // Parse the query string to extract the 'code' parameter
  const params = new URLSearchParams(window.location.search);
  const code = params.get('code');
  if (code) {
    try {
      const accessToken = await garmin.getAccessToken(code);
      // You can now use the access token to make authorized requests
      console.log('Access Token:', accessToken);
      // Optionally, store the access token for future use (e.g., in localStorage)
      localStorage.setItem('garminAccessToken', accessToken);
    } catch (error) {
      console.error('Failed to get the access token:', error);
    }
  }
}
// Call the function when this file is loaded, if applicable
handleAuthCallback();

This code checks for the authorization code in the URL, retrieves the access token using the GarminConnect class, and logs it. You can then store and use this token to make subsequent authenticated API calls to Garmin Connect.

Summary of Changes and File Locations

Add the Axios CDN script to your index.html file.
Create a new file named garminConnectIntegration.ts containing the integration class code.
Update your main application file (for example, app.ts) with code to initiate Garmin Connect authorization.
Create or update an authentication callback handler file (for example, authCallback.ts) to handle the redirect from Garmin Connect and retrieve the access token.

Rapid Dev was an exceptional project management organization and the best development collaborators I've had the pleasure of working with.
