Configuration

Preparation

Get clientId and clientSecret from Google Cloud Console

• Go to Google Cloud Console
• If you don't have a project, create one and then go to the APIs & Services tab.
• From the library, enable the Google Drive API.
• Then, from the Credentials section, create credentials for a Web application.
• After selecting the Web application option, you should see a field labeled Authorized redirect URIs.
  • Add the backend URI to that field: https://{yourdomain}/Api/Auth/Callback (ex: https://yourdeployment-1234.up.railway.app/Api/Auth/Callback)
• In the OAuth consent screen page, enter the following information:
  • App name: Enter a name for your application.
  • User type: Select the type of users who use your application.
  • Scopes: Select the scopes that your application needs to access Google Drive.
• Save clientId and clientSecret somewhere safe.

---

• NOTE: Your OAuth application does not need to be in production mode, you can leave it in development mode.

How Can I Get Folder and Shared Drive Id’s From Google Drive?

Backend Configuration

• appsettings.json (In production)
• appsettings.Development.json

  "GDrive": {
        "ClientId": "", // <- Enter the clientId you received from Google Cloud Console here
        "ClientSecret": "ExampleClientSecret", // <- Enter the clientSecret you received from Google Cloud Console here
        "EnableSharedDrive": false, // <- Set to true if you want to enable the shared drive feature
        "EnableMainFolderCheck": true,
        "MainFolderId": "", // <- Enter the Google Drive ID of the folder you want to share
        "SharedDriveId": "", // <- If the shared drive feature is enabled, enter the shared drive ID you want to share here
        "AppName": "GreenDrive",
        "AuthFolder": "AuthCache"
    }

• NOTE: Please do not disable MainFolderCheck, even though it may slow down API responses! If you disable it, people who somehow got the ID of another folder in your Google Drive will be able to access it with simple hacks via GreenDrive.

Deploy Backend to Railway (Optional)

• Go to Railway dashboard

• Click the "New Project" button and select "Empty Project".

• Click the "New Service" button and select "Empty Service".

• Go to your terminal and navigate to the backend folder:

cd backend

• Run these commands:

railway link
railway up -s <yourservice>

• Once the deployment is complete, create a domain for your service in Railway

  • Click the "Domains" tab and click the "Create Domain" button.

• Save the domain somewhere safe

Google Authorization

Backend will give you a url path with a token in it for verification on the first start, you can see it locally in the console or in the logs of other providers.

It should look like this:

http://{yourdomain}/Api/Auth?token=XXXYYYZZZ

Let's assume that you have deployed the backend to Railway.

Your domain probably looks like this:

https://x-y-z-1234.up.railway.app/

Concatenate the URL path you got from the console and make it look like this:

https://x-y-z-1234.up.railway.app/Api/Auth?token=XXXYYYZZ

Open this URL in your browser, it will take you to the Google sign-in page. On this page, grant the necessary Google Drive permissions and complete the sign-in. If the process is successful, you will then be redirected to the /Api/List URL. If you see the contents of the folder you specified as mainFolderId in the configuration, congratulations, you have completed the authorization.

Frontend Configuration

• config.json

{
    "appName": "GreenDrive",
    "apiUrl": "http://localhost:8081", // (Required) Enter the backend API URL without the trailing slash here
    "language": "en_us", // Select file explorer language here
    "tg_ads": ... // Configure Telegram ad pop-up here
    "adsense": ... // Configure adsense advertisements here
    "gtag": ... // // Configure gtag.js here
    "language_strings": ... // Modify or define languages here
}

Deploy Frontend to Vercel (Optional)

• Navigate to the frontend folder
• Run the Vercel CLI and follow the instructions to deploy your application

cd frontend
vercel

Your project should now be accessible from the domain of the platform you deployed or from localhost.
