Lovable and Binance API integration: Step-by-Step Guide 2025

 

Setting Up the Project Dependencies

 

• Create or open your package.json file in the root directory of your Lovable project.
• Add the Binance API dependency by manually inserting the following code snippet. Since Lovable does not have a terminal, this code instructs Lovable to install the dependency automatically when reading the package file.
• Paste this snippet inside your existing package.json (or create a new file if it doesn’t exist):

  
  {
    "name": "lovable-project",
    "version": "1.0.0",
    "dependencies": {
      "binance-api-node": "^0.12.0"
    },
    "scripts": {
      "start": "node dist/index.js"
    }
  }
      

 

Creating the TypeScript Configuration File

 

• Create a new file named tsconfig.json in the root directory of your project.
• Insert the following configuration to define the compilation settings for your TypeScript code:
• Paste this snippet into the file:

  
  {
    "compilerOptions": {
      "target": "ES6",
      "module": "commonjs",
      "outDir": "./dist",
      "strict": true,
      "esModuleInterop": true,
      "skipLibCheck": true
    },
    "include": ["src/*/"]
  }
      

 

Creating the Binance Service File

 

• Within your project structure, create a new folder called src if it does not already exist.
• Inside the src folder, create a new file named binanceService.ts.
• Add the following TypeScript code that integrates with the Binance API. This service initializes the Binance client and provides an example function to retrieve the price of Bitcoin:
• Paste this snippet into binanceService.ts:

  
  import Binance from 'binance-api-node';
  
  // Optionally, configure the Binance client with your API keys
  const client = Binance({
    apiKey: 'YOURBINANCEAPI_KEY',
    apiSecret: 'YOURBINANCEAPI_SECRET'
  });
  // Example function to retrieve the current price of Bitcoin (BTCUSDT)
  export async function getBTCPrice(): Promise {
    try {
      const prices = await client.prices({ symbol: 'BTCUSDT' });
      return prices.BTCUSDT;
    } catch (error) {
      console.error('Error fetching BTC price:', error);
      throw error;
    }
  }
      

  
  

 

Modifying the Main Application File

 

• If your Lovable project has an entry file (for example, src/index.ts), open it. Otherwise, create one inside the src folder named index.ts.
• In this file, import the function from binanceService.ts and use it—for example, to log the current BTC price to the console.
• Paste this snippet into index.ts:

  
  import { getBTCPrice } from './binanceService';
  
  async function showBTCPrice(): Promise {
    try {
      const price = await getBTCPrice();
      console.log('Current BTC Price (BTCUSDT):', price);
    } catch (error) {
      console.error('Could not retrieve BTC price.');
    }
  }
  showBTCPrice();
      

  
  

 

Building and Running Your Project in Lovable

 

• Lovable will automatically recognize the tsconfig.json file and compile your TypeScript code. Ensure that your project settings include the build step to compile files from the src folder to the dist folder.
• Since Lovable does not support a terminal, use the built-in features to trigger a build. This is typically configured in the project settings or via a specified build script. The script defined in your package.json ("start": "node dist/index.js") will run your compiled code.
• After compilation, use Lovable’s interface to launch the application. Your main file (dist/index.js) will execute and log the current BTC price.

 

Note on API Keys

 

• Replace YOURBINANCEAPIKEY and YOURBINANCEAPISECRET in the binanceService.ts file with your actual Binance API credentials.
• If Lovable supports environment variable management, store your API keys securely and modify the client configuration to read from those variables.
