MongoDB Atlas Checker
Verify MongoDB Atlas setup and configuration. Identifies configuration issues, missing environment variables, incorrect connection strings, and ensures proper database setup.
When to Use
- Verifying MongoDB Atlas backend setup
- Checking connection string configuration
- Validating environment variable setup
- Troubleshooting database connection issues
- Auditing database setup before deployment
Quick Checklist
1. Environment Variables
MONGODB_URI exists (not hardcoded)- Uses
mongodb+srv:// protocol (required for Atlas)
- Includes database name
- Includes
retryWrites=true&w=majority
- No credentials in
.env.example
2. Connection String Format
mongodb+srv://<username>:<password>@<cluster-host>/<database>?retryWrites=true&w=majority
3. Driver Installation
mongoose or mongodb package installed- In dependencies (not devDependencies)
4. Connection Setup
- Singleton pattern (Next.js)
MongooseModule.forRoot() (NestJS)- Error handling implemented
5. Atlas Configuration
- IP whitelist configured
- Database user exists with permissions
- SSL/TLS enabled (default with
mongodb+srv://)
Common Issues
| Issue | Solution |
|---|
Missing MONGODB_URI | Add to .env.local or .env |
| Wrong protocol | Use mongodb+srv:// not mongodb:// |
| Multiple connections (Next.js) | Use singleton pattern |
| Connection timeout | Check IP whitelist in Atlas |
| Auth failed | Verify credentials, URL-encode special chars |
Recommended Connection Options
{
retryWrites: true,
w: 'majority',
maxPoolSize: 10,
serverSelectionTimeoutMS: 5000,
bufferCommands: false,
}
