Lovable and Mercurial integration: Step-by-Step Guide 2025

 

Step 1: Create the Mercurial Integration File

 

• Within your Lovable project’s source folder (for example, src), create a new file named mercurialIntegration.ts.
• This file will contain the TypeScript class responsible for interacting with Mercurial-related operations.

 

Step 2: Write the MercurialService Class Code

 

• In mercurialIntegration.ts, add the following code.

  
  import axios from 'axios';
  
  export class MercurialService {
    private apiBaseUrl: string;
    private authToken: string;
    constructor(apiBaseUrl: string, authToken: string) {
      this.apiBaseUrl = apiBaseUrl;
      this.authToken = authToken;
    }
    public async cloneRepo(repoUrl: string, destinationPath: string): Promise {
      // Mercurial cloning via HTTP API is provider-specific.
      // Replace this placeholder with your provider’s API call if available.
      console.log(Cloning repository from ${repoUrl} into ${destinationPath});
    }
    public async commitChanges(message: string): Promise {
      // This is a placeholder: Implement commit functionality through an API call if your provider supports it.
      console.log(Committing changes with message: "${message}");
    }
    public async pushChanges(): Promise {
      // This is a placeholder: Implement push functionality through an API call if your provider supports it.
      console.log('Pushing changes to the remote repository');
    }
  }
      

  
  

 

Step 3: Use the MercurialService in Your Project

 

• Create or open a main file in your project (for example, app.ts).
• Import and instantiate MercurialService, then call its methods where needed.

  
  import { MercurialService } from './mercurialIntegration';
  
  // Replace with your actual API base URL and authentication token if your Mercurial provider supports API integration.
  const hgService = new MercurialService('https://api.mercurialprovider.com', 'your-auth-token');
  // Example usage: integrating Mercurial commands into your project workflow.
  async function updateRepository() {
    await hgService.cloneRepo('https://repo.url/your-repo', '/local/path');
    await hgService.commitChanges('Updated project with Mercurial integration');
    await hgService.pushChanges();
  }
  updateRepository();
      

  
  

 

Step 4: Adding Dependencies Without a Terminal

 

• Since Lovable does not provide a terminal, dependency management is handled by adding entries to your project’s configuration file.
• If your project uses a package.json, manually add the following dependency entry to include Axios:

  
  {
    "dependencies": {
      "axios": "^0.27.2"
    }
  }
      

• This ensures that Axios is available when the project is loaded by Lovable.

 

Step 5: Integrate the New Code with the Existing Project

 

• Review all parts of your project where version control operations may be needed.
• Insert calls to the MercurialService methods (for example, when triggering updates or deployments) in the relevant business logic sections.
• Ensure that your authentication tokens and API URLs are correctly set for your Mercurial hosting service, if applicable.

 

Step 6: Testing and Debugging

 

• Run your Lovable project following your project’s usual start-up procedure.
• Check the console or log output to verify that the Mercurial operations are being simulated as expected.
• If you encounter any issues, review the code for typos and ensure that the API endpoints and tokens are correctly configured.
