Lovable and MongoDB Atlas integration: Step-by-Step Guide 2025

 

Adding MongoDB as a Dependency in Your Lovable Project

 

Since Lovable doesn’t allow terminal access, you must manually add the MongoDB dependency in your project's configuration. Open your package.json file (or equivalent configuration file) and add the following dependency entry. This tells Lovable to include the MongoDB driver with your project.

{
  "dependencies": {
    "mongodb": "^4.7.0"
  }
}

Make sure this snippet is placed inside the main JSON object of your package.json file. Save the file after adding the dependency.

 

Creating the MongoDB Connection Module

 

Create a new file in your project. You might name it mongodbClient.ts and place it in the root folder or under a dedicated folder (for example, src/util). This file will contain the logic for connecting to your MongoDB Atlas database. Replace yourconnectionstring_here with your actual MongoDB Atlas connection string and YourDatabaseName with your database name.

import { MongoClient, Db } from 'mongodb';

const uri = process.env.MONGODBURI || "yourconnectionstringhere";

const client = new MongoClient(uri, {
  useNewUrlParser: true,
  useUnifiedTopology: true
});

let database: Db;

export const connectToDatabase = async (): Promise => {
  if (database) {
    return database;
  }
  await client.connect();
  database = client.db('YourDatabaseName');
  console.log('Connected successfully to MongoDB Atlas');
  return database;
};

Place this file alongside your other project files so you can import it in your application’s code.

 

Configuring Your MongoDB Atlas Connection String

 

If you can set environment variables in Lovable, add your MongoDB connection string via the project’s configuration or secrets manager under the key MONGODBURI. If you cannot use an environment variable, directly replace yourconnectionstringhere in the mongodbClient.ts file with your actual connection string.

 

Integrating MongoDB Connection into Your Main Project Code

 

In the main file of your Lovable project (for example, server.ts or app.ts), import the connection function from the module you created. Then, call it at the start of your server initialization to establish a connection. This is where your project will start interacting with MongoDB Atlas.

import { connectToDatabase } from './mongodbClient';

(async () => {
  try {
    const db = await connectToDatabase();
    // You can now use the connection to perform database operations.
    // For example, to access a collection:
    // const usersCollection = db.collection('users');
    console.log('Database is ready for operations.');
  } catch (error) {
    console.error('Error connecting to MongoDB Atlas:', error);
  }
})();

// Your existing Lovable project code can follow here.

Make sure the path in the import statement ('./mongodbClient') correctly reflects the location of your mongodbClient.ts file relative to your main application file.

 

Testing Your MongoDB Integration

 

After integrating the MongoDB connection code, save all your changes. When Lovable runs your project, the connection module should automatically attempt to connect to MongoDB Atlas. You can use the console logs to check whether the connection was successful.

 

Using the Database in Your Application

 

Now that your MongoDB Atlas connection is established, you can use the db instance to interact with collections and documents inside your application logic. Simply import the connectToDatabase function wherever needed, initiate the connection (if not already connected), and perform operations like querying, updating, or inserting documents.

 

By following these steps and inserting the code snippets in the specified files, your Lovable project will be integrated with MongoDB Atlas without needing to use any terminal commands.
