Bolt.new AI and MongoDB Atlas integration: Step-by-Step Guide 2025

 

Step 1: Configuring Dependencies in Your Project

 

• Create or update your package.json file to include the necessary dependency for MongoDB. Since Bolt.new AI doesn't have a terminal, add the dependency manually in your file. For example, add the following section if it doesn’t already exist:

• 
  {
    "name": "bolt-mongo-integration",
    "version": "1.0.0",
    "dependencies": {
      "mongodb": "^5.7.0"
    }
    // Include other project settings as needed
  }
      

• This ensures that when your project runs, MongoDB’s Node.js driver is available.

 

Step 2: Creating a MongoDB Connection Module

 

• Create a new file in your project directory named db.ts. This file will handle the connection to MongoDB Atlas.
• Insert the following TypeScript code into db.ts. This code imports the MongoClient from the mongodb package, reads your MongoDB connection string from environment variables, and exports helper functions to connect and get the database.

• 
  import { MongoClient } from "mongodb";
  
  // Ensure you set MONGO_URI in your environment variables in Bolt.new AI's secrets management.
  const uri = process.env.MONGO_URI as string;
  if (!uri) {
    throw new Error("Please define the MONGO_URI environment variable inside Bolt.new AI secrets.");
  }
  const client = new MongoClient(uri);
  export async function connectToDB(): Promise {
    try {
      await client.connect();
      console.log("Connected to MongoDB Atlas successfully.");
    } catch (error) {
      console.error("Error connecting to MongoDB:", error);
      throw error;
    }
  }
  export function getDb(dbName: string) {
    return client.db(dbName);
  }
      

  
  


• This file handles both the connection and providing the database instance for further operations.

 

Step 3: Integrating the MongoDB Connection in Your Main Application File

 

• Open your main application file (for example, index.ts) where you want to start interacting with MongoDB.
• Import the functions from the db.ts module and call the connectToDB function during your app initialization. Insert the following code snippet at the beginning of your main file:

• 
  import { connectToDB, getDb } from "./db";
  
  async function initializeApp() {
    try {
      await connectToDB();
      // Replace 'yourDatabaseName' with the actual name of your database.
      const db = getDb("yourDatabaseName");
      // Now you can use db to perform operations, for example:
      // const collection = db.collection("yourCollectionName");
      // const result = await collection.find({}).toArray();
      console.log("MongoDB is ready for operations.");
    } catch (error) {
      console.error("Failed to initialize MongoDB connection:", error);
    }
  }
  initializeApp();
  // Your existing Bolt.new AI project code continues here.
      

  
  


• This ensures that your application establishes a connection to MongoDB Atlas before proceeding with other operations.

 

Step 4: Setting Up Environment Variables

 

• In Bolt.new AI, use the Secrets or Environment Variables configuration feature to add your MongoDB connection string.
• Add a new secret with the key MONGO_URI and paste your MongoDB Atlas connection string as the value.
• This setup allows the db.ts file to read the connection string securely.

 

Step 5: Verifying the Integration

 

• After implementing the above changes, save all your files.
• Run your Bolt.new AI project. Watch the console/log output for the message "Connected to MongoDB Atlas successfully." This confirms that the connection is established.
• If you encounter any errors, double-check your MONGO_URI value and ensure that your MongoDB Atlas cluster is set up to accept connections from your environment.
