Desktop Development Guide

Architecture Overview

LobeHub desktop is built on Electron with main-renderer architecture:

1. Main Process (apps/desktop/src/main): App lifecycle, system APIs, window management
2. Renderer Process : Reuses web code from src/
3. Preload Scripts (apps/desktop/src/preload): Securely expose main process to renderer

Adding New Desktop Features

1. Create Controller

Location: apps/desktop/src/main/controllers/

import { ControllerModule, IpcMethod } from '@/controllers';

export default class NewFeatureCtr extends ControllerModule {
  static override readonly groupName = 'newFeature';

  @IpcMethod()
  async doSomething(params: SomeParams): Promise<SomeResult> {
    // Implementation
    return { success: true };
  }
}

Register in apps/desktop/src/main/controllers/registry.ts.

2. Define IPC Types

Location: packages/electron-client-ipc/src/types.ts

export interface SomeParams {
  /* ... */
}
export interface SomeResult {
  success: boolean;
  error?: string;
}

3. Create Renderer Service

Location: src/services/electron/

import { ensureElectronIpc } from '@/utils/electron/ipc';

const ipc = ensureElectronIpc();

export const newFeatureService = async (params: SomeParams) => {
  return ipc.newFeature.doSomething(params);
};

4. Implement Store Action

Location: src/store/

5. Add Tests

Location: apps/desktop/src/main/controllers/__tests__/

Detailed Guides

See references/ for specific topics:

• Feature implementation : references/feature-implementation.md
• Local tools workflow : references/local-tools.md
• Menu configuration : references/menu-config.md
• Window management : references/window-management.md

Best Practices

1. Security : Validate inputs, limit exposed APIs
2. Performance : Use async methods, batch data transfers
3. UX : Add progress indicators, provide error feedback
4. Code organization : Follow existing patterns, add documentation
