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

typescript

{
  retryWrites: true,
  w: 'majority',
  maxPoolSize: 10,
  serverSelectionTimeoutMS: 5000,
  bufferCommands: false,
}
