项目架构与技术栈分析
核心技术架构
Cherry Studio采用现代化的Electron + React + TypeScript技术栈，具备出色的跨平台能力：
当前平台支持矩阵
| 平台 | 支持状态 | 构建工具 | 打包格式 |
|---|---|---|---|
| Windows | ✅ 完全支持 | electron-builder | exe/msi |
| macOS | ✅ 完全支持 | electron-builder | dmg/pkg |
| Linux | ✅ 完全支持 | electron-builder | AppImage/deb |
| HarmonyOS PC | 🚧 开发中 | 鸿蒙SDK | HAP |
HarmonyOS平台适配技术挑战
1. 运行时环境差异
HarmonyOS采用ArkTS/ArkUI开发框架，与Electron的Chromium+Node.js架构存在显著差异：
// Electron主进程典型代码结构
import { app, BrowserWindow } from 'electron';
import * as path from 'path';
function createWindow(): void {
const mainWindow = new BrowserWindow({
width: 1200,
height: 800,
webPreferences: {
nodeIntegration: true,
contextIsolation: false
}
});
mainWindow.loadFile('index.html');
}
app.whenReady().then(createWindow);
2. 原生API兼容性
需要处理的API差异包括：
| Electron API | HarmonyOS等效方案 | 适配策略 |
|---|---|---|
electron.dialog | @ohos.promptAction | 抽象层封装 |
electron.menu | @ohos.UiTest | 自定义实现 |
electron.shell | @ohos.app.ability | 桥接适配 |
electron.ipc | @ohos.rpc | 消息协议转换 |
3. 构建与打包体系
现有构建配置需要针对HarmonyOS进行调整：
// electron-builder.yml 配置示例
appId: com.cherryhq.studio
productName: Cherry Studio
directories:
output: dist
buildResources: build
files:
- "out/**/*"
- "!out/**/*.map"
extraMetadata:
main: out/main/index.js
// 需要新增HarmonyOS特定配置
harmonyOS:
sdkPath: /path/to/harmonyos/sdk
hapConfig:
package: com.cherryhq.studio
name: Cherry Studio
versionName: 1.0.0
versionCode: 1
鸿蒙适配技术实现方案
1. 架构分层设计
采用分层架构确保代码可维护性和平台无关性：
2. 平台检测与适配器模式
// 平台检测与服务定位
export enum Platform {
WINDOWS = 'win32',
MACOS = 'darwin',
LINUX = 'linux',
HARMONYOS = 'harmonyos'
}
export class PlatformService {
private static currentPlatform: Platform;
static detectPlatform(): Platform {
const platform = process.platform;
// HarmonyOS检测逻辑
if (this.isHarmonyOS()) {
return Platform.HARMONYOS;
}
return platform as Platform;
}
private static isHarmonyOS(): boolean {
// 鸿蒙系统检测策略
return navigator.userAgent.includes('HarmonyOS') ||
process.env.OHOS_ARCH !== undefined;
}
static getPlatformAdapter(): PlatformAdapter {
switch (this.currentPlatform) {
case Platform.HARMONYOS:
return new HarmonyOSAdapter();
default:
return new ElectronAdapter();
}
}
}
// 平台适配器接口
interface PlatformAdapter {
showDialog(options: DialogOptions): Promise<DialogResult>;
openFile(options: OpenFileOptions): Promise<string>;
showNotification(title: string, body: string): void;
getSystemInfo(): SystemInfo;
}
3. HarmonyOS特定实现
// HarmonyOS平台适配器实现
class HarmonyOSAdapter implements PlatformAdapter {
async showDialog(options: DialogOptions): Promise<DialogResult> {
try {
// 使用鸿蒙的promptAction模块
const promptAction = require('@ohos.promptAction');
const result = await promptAction.showDialog({
title: options.title,
message: options.message,
buttons: options.buttons
});
return {
buttonIndex: result.index,
checkboxChecked: false // 鸿蒙暂不支持多选
};
} catch (error) {
console.error('HarmonyOS dialog error:', error);
throw error;
}
}
async openFile(options: OpenFileOptions): Promise<string> {
// 使用鸿蒙文件系统API
const fileIO = require('@ohos.file.fs');
const wantAgent = require('@ohos.app.ability.wantAgent');
// 文件选择器实现
const selectedFile = await this.showFilePicker();
return selectedFile;
}
private async showFilePicker(): Promise<string> {
// 鸿蒙文件选择器实现
return new Promise((resolve) => {
// 实际实现会使用鸿蒙的FilePicker组件
resolve('/selected/file/path');
});
}
}
构建与部署流水线
1. 多平台构建配置
// package.json 构建脚本扩展
{
"scripts": {
"build:harmonyos": "npm run build:renderer && harmonyos-build",
"build:harmonyos:debug": "HARMONYOS_DEBUG=true npm run build:harmonyos",
"build:harmonyos:release": "HARMONYOS_RELEASE=true npm run build:harmonyos",
"dev:harmonyos": "harmonyos-dev-server"
}
}
2. CI/CD集成
# GitHub Actions 工作流配置
name: Build and Deploy
on:
push:
branches: [ main, harmonyos-dev ]
pull_request:
branches: [ main ]
jobs:
build-harmonyos:
runs-on: ubuntu-latest
if: contains(github.event.head_commit.message, 'harmonyos') || github.ref == 'refs/heads/harmonyos-dev'
steps:
- uses: actions/checkout@v4
- name: Setup HarmonyOS SDK
uses: harmonyos/setup-sdk@v1
with:
sdk-version: '4.0.0'
- name: Install dependencies
run: npm ci
- name: Build HarmonyOS package
run: npm run build:harmonyos:release
- name: Upload artifacts
uses: actions/upload-artifact@v4
with:
name: cherry-studio-harmonyos
path: dist/harmonyos/*.hap
性能优化策略
1. 资源加载优化
// 鸿蒙平台资源加载优化
class HarmonyOSResourceLoader {
private static resourceCache: Map<string, any> = new Map();
static async loadResource(resourcePath: string): Promise<any> {
if (this.resourceCache.has(resourcePath)) {
return this.resourceCache.get(resourcePath);
}
// 鸿蒙特定的资源加载方式
const resource = await this.loadHarmonyOSResource(resourcePath);
this.resourceCache.set(resourcePath, resource);
return resource;
}
private static async loadHarmonyOSResource(path: string): Promise<any> {
const resMgr = require('@ohos.resourceManager');
const context = require('@ohos.app.ability.Context');
try {
const resourceManager = resMgr.getResourceManager();
return await resourceManager.getResource(path);
} catch (error) {
console.warn('Failed to load resource from HarmonyOS bundle:', error);
// 回退到传统加载方式
return this.fallbackLoad(path);
}
}
}
2. 内存管理优化
// 鸿蒙内存管理最佳实践
class HarmonyOSMemoryManager {
private static memoryWatcher: any;
static initMemoryMonitoring(): void {
if (this.isHarmonyOS()) {
const systemAbility = require('@ohos.systemAbility');
this.memoryWatcher = systemAbility.createSystemAbility({
abilityType: systemAbility.AbilityType.MEMORY
});
this.memoryWatcher.on('memoryPressure', (level: number) => {
this.handleMemoryPressure(level);
});
}
}
private static handleMemoryPressure(level: number): void {
switch (level) {
case 1: // LOW
this.cleanupCaches();
break;
case 2: // MEDIUM
this.cleanupCaches();
this.releaseUnusedResources();
break;
case 3: // HIGH
this.emergencyCleanup();
break;
}
}
private static cleanupCaches(): void {
// 清理图片缓存、临时数据等
ImageCache.clear();
TempDataManager.cleanup();
}
}
测试与质量保障
1. 跨平台测试策略
// 平台兼容性测试套件
describe('Platform Compatibility Tests', () => {
const platforms = ['win32', 'darwin', 'linux', 'harmonyos'];
platforms.forEach(platform => {
describe(`Platform: ${platform}`, () => {
beforeEach(() => {
jest.mock('../src/utils/platform', () => ({
getPlatform: jest.fn().mockReturnValue(platform)
}));
});
test('File dialog should work', async () => {
const { showDialog } = await import('../src/services/dialog');
const result = await showDialog({ title: 'Test' });
expect(result).toBeDefined();
// 平台特定的断言
if (platform === 'harmonyos') {
expect(result).toHaveProperty('harmonyosSpecificField');
}
});
test('Notification service', async () => {
const { showNotification } = await import('../src/services/notification');
await expect(showNotification('Test', 'Message'))
.resolves
.not.toThrow();
});
});
});
});
