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

 

Adding the Sketch Dependency to Your Lovable Project

 

• Since Lovable doesn’t have a terminal, you must manually add the Sketch dependency to your project’s configuration.
• Open your project’s package.json (if it exists; otherwise, create one in your project’s root directory).
• Add the following entry inside the "dependencies" section to include the Sketch module:

  
  {
    "dependencies": {
      "sketch": "^49.0.0"
    }
  }
      

• This will tell Lovable (or any build process in your project) to load the Sketch module code when your project runs.

 

Creating a New TypeScript File for Sketch Integration

 

• Create a new folder called integrations in your project source directory (for example, under src). This helps separate integration code from the rest of your application.
• Create a new file named sketchIntegration.ts inside the integrations folder.
• Insert the following TypeScript code in sketchIntegration.ts:

  
  import { Document } from 'sketch';
  
  export class SketchIntegration {
    private filePath: string;
    constructor(filePath: string) {
      this.filePath = filePath;
    }
    loadSketchFile() {
      try {
        // Attempt to open the Sketch file using the Sketch API
        const doc = Document.open(this.filePath);
        console.log('Sketch file loaded successfully:', doc);
        return doc;
      } catch (error) {
        console.error('Error loading Sketch file:', error);
        return null;
      }
    }
    exportArtboards(doc: Document) {
      if (!doc) {
        console.error('No document loaded. Cannot export artboards.');
        return;
      }
      try {
        // Example: Retrieve layers named "Artboard" from the Sketch document
        const artboards = doc.getLayersNamed('Artboard');
        artboards.forEach(artboard => {
          console.log('Exporting artboard:', artboard.name);
          // Insert your export logic here
        });
      } catch (error) {
        console.error('Error exporting artboards:', error);
      }
    }
  }
      

  
  


• This file defines a class that handles loading a Sketch file and performing operations such as exporting artboards.

 

Integrating Sketch Integration Code with Your Main Application

 

• Open your main project file (for example, app.ts or main.ts) where you manage application logic.
• At the top of the file, import the Sketch integration module by adding the following code:

  
  import { SketchIntegration } from './integrations/sketchIntegration';
      

• Insert the following code snippet in your main file to initialize and use the Sketch integration:

  
  const sketchFilePath = 'path/to/your/design.sketch';  // Replace with the actual file path to your Sketch file
  const sketchIntegration = new SketchIntegration(sketchFilePath);
  
  // Load the Sketch file
  const doc = sketchIntegration.loadSketchFile();
  // If the document loads successfully, process the artboards
  if (doc) {
    sketchIntegration.exportArtboards(doc);
  }
      

  
  


• This snippet creates an instance of your Sketch integration class, loads a Sketch file, and executes export logic for its artboards. Adjust the sketchFilePath and export logic as needed for your project.

 

Finalizing the Integration

 

• Ensure that all files are saved in their correct locations:
• package.json is in your project root with the Sketch dependency.
• src/integrations/sketchIntegration.ts contains the integration logic.
• Your main file (for example, src/app.ts) includes the integration code that imports and uses SketchIntegration.
• Because Lovable does not provide a terminal, verify that your project’s build process automatically picks up changes from package.json and compiles your TypeScript files.
• You should now have a fully integrated solution to work with Sketch files in your Lovable project.
