HarmonyOS NEXT应用发布与版本管理指南：规范化发布流程

1. 版本管理基础

1.1 版本号规范

版本类型	格式	说明	示例
主版本号	X.0.0	重大更新	2.0.0
次版本号	X.Y.0	功能更新	2.1.0
修订号	X.Y.Z	问题修复	2.1.1

1.2 版本管理实现

// version.config.ts
export interface VersionInfo {major: number;minor: number;patch: number;build: number;timestamp: number;
}class VersionManager {private static readonly VERSION_FILE = 'version.json';private currentVersion: VersionInfo;constructor() {this.loadVersion();}// 加载版本信息private async loadVersion(): Promise<void> {try {const content = await readFile(this.VERSION_FILE);this.currentVersion = JSON.parse(content);} catch (error) {this.currentVersion = {major: 1,minor: 0,patch: 0,build: 0,timestamp: Date.now()};}}// 更新版本号async updateVersion(type: 'major' | 'minor' | 'patch'): Promise<void> {switch (type) {case 'major':this.currentVersion.major++;this.currentVersion.minor = 0;this.currentVersion.patch = 0;break;case 'minor':this.currentVersion.minor++;this.currentVersion.patch = 0;break;case 'patch':this.currentVersion.patch++;break;}this.currentVersion.build++;this.currentVersion.timestamp = Date.now();await this.saveVersion();}// 获取版本字符串getVersionString(): string {const { major, minor, patch } = this.currentVersion;return `${major}.${minor}.${patch}`;}
}

2. 发布流程管理

2.1 发布流程配置

// release.config.ts
interface ReleaseConfig {environment: 'development' | 'staging' | 'production';channels: string[];requiredTests: string[];approvers: string[];
}class ReleaseManager {private config: ReleaseConfig;private versionManager: VersionManager;// 初始化发布配置async initialize(): Promise<void> {this.config = await this.loadConfig();this.versionManager = new VersionManager();}// 创建发布async createRelease(type: 'major' | 'minor' | 'patch'): Promise<Release> {// 更新版本号await this.versionManager.updateVersion(type);// 创建发布记录const release = {version: this.versionManager.getVersionString(),timestamp: Date.now(),changes: await this.getChangeLog(),status: 'pending'};// 启动发布流程await this.startReleaseProcess(release);return release;}// 发布流程private async startReleaseProcess(release: Release): Promise<void> {// 运行测试await this.runRequiredTests();// 获取审批await this.getApprovals();// 准备发布包await this.prepareReleasePackage();// 发布到渠道await this.deployToChannels();}
}

2.2 变更日志管理

class ChangelogManager {private static readonly CHANGELOG_FILE = 'CHANGELOG.md';// 添加变更记录static async addEntry(version: string,changes: Change[]): Promise<void> {const entry = this.formatEntry(version, changes);await this.prependToChangelog(entry);}// 格式化变更记录private static formatEntry(version: string,changes: Change[]): string {const timestamp = new Date().toISOString();let entry = `\n## [${version}] - ${timestamp}\n\n`;// 按类型分组变更const grouped = this.groupChanges(changes);for (const [type, items] of Object.entries(grouped)) {entry += `### ${type}\n`;items.forEach(item => {entry += `- ${item.description}\n`;});entry += '\n';}return entry;}// 分组变更private static groupChanges(changes: Change[]): Record<string, Change[]> {return changes.reduce((groups, change) => {const { type } = change;if (!groups[type]) {groups[type] = [];}groups[type].push(change);return groups;}, {});}
}

3. 应用打包配置

3.1 打包配置管理

// build.config.ts
interface BuildConfig {appId: string;version: string;environment: string;optimization: {minify: boolean;sourceMap: boolean;};signing: {keystore: string;alias: string;password: string;};
}class BuildManager {private config: BuildConfig;// 初始化构建配置async initialize(env: string): Promise<void> {this.config = await this.loadBuildConfig(env);}// 构建应用async buildApp(): Promise<BuildResult> {try {// 准备构建环境await this.prepareBuildEnvironment();// 执行构建const result = await this.executeBuild();// 签名应用包await this.signPackage(result.packagePath);// 验证构建结果await this.validateBuild(result);return result;} catch (error) {console.error('Build failed:', error);throw error;}}// 签名应用包private async signPackage(packagePath: string): Promise<void> {const { signing } = this.config;// 实现签名逻辑}
}

3.2 资源优化

class ResourceOptimizer {// 优化图片资源static async optimizeImages(directory: string): Promise<void> {const images = await this.findImages(directory);for (const image of images) {await this.compressImage(image);}}// 优化代码static async optimizeCode(directory: string): Promise<void> {// 代码压缩await this.minifyCode(directory);// 删除未使用的代码await this.removeUnusedCode(directory);// 优化导入await this.optimizeImports(directory);}// 生成资源映射static async generateResourceMap(directory: string): Promise<ResourceMap> {// 实现资源映射生成逻辑return {};}
}

4. 持续集成与部署

4.1 CI/CD配置

# pipeline.yml
name: Release Pipelinestages:- name: Buildsteps:- name: Setup Environmentscript: |npm installnpm run build- name: Run Testsscript: |npm run testnpm run e2e- name: Build Packagescript: |npm run build:prod- name: Deploysteps:- name: Deploy to Stagingscript: |npm run deploy:staging- name: Run Integration Testsscript: |npm run test:integration- name: Deploy to Productionscript: |npm run deploy:prod

4.2 自动化部署

class DeploymentManager {private config: DeploymentConfig;// 部署应用async deploy(environment: string,version: string): Promise<DeploymentResult> {try {// 验证部署环境await this.validateEnvironment(environment);// 准备部署包const package = await this.prepareDeployment(version);// 执行部署await this.executeDeployment(package, environment);// 验证部署await this.validateDeployment(environment);return {success: true,environment,version,timestamp: Date.now()};} catch (error) {console.error('Deployment failed:', error);throw error;}}// 回滚部署async rollback(environment: string,version: string): Promise<void> {// 实现回滚逻辑}
}

5. 应用更新机制

5.1 更新检查服务

class UpdateService {private static readonly UPDATE_CHECK_INTERVAL = 3600000; // 1小时// 检查更新async checkForUpdates(): Promise<UpdateInfo | null> {try {const currentVersion = await this.getCurrentVersion();const latestVersion = await this.getLatestVersion();if (this.shouldUpdate(currentVersion, latestVersion)) {return {version: latestVersion.version,size: latestVersion.size,changes: latestVersion.changes,mandatory: latestVersion.mandatory};}return null;} catch (error) {console.error('Update check failed:', error);return null;}}// 下载更新async downloadUpdate(version: string): Promise<boolean> {try {// 下载更新包const package = await this.downloadPackage(version);// 验证包完整性if (!await this.verifyPackage(package)) {throw new Error('Package verification failed');}// 准备安装await this.prepareInstallation(package);return true;} catch (error) {console.error('Update download failed:', error);return false;}}
}

5.2 增量更新实现

class IncrementalUpdateManager {// 生成增量更新包static async generatePatch(oldVersion: string,newVersion: string): Promise<PatchInfo> {// 获取版本差异const diff = await this.calculateDiff(oldVersion,newVersion);// 生成补丁包const patch = await this.createPatch(diff);// 验证补丁await this.verifyPatch(patch, oldVersion, newVersion);return {version: newVersion,patchSize: patch.size,compatibility: [oldVersion],hash: patch.hash};}// 应用增量更新static async applyPatch(currentVersion: string,patch: PatchInfo): Promise<boolean> {try {// 验证兼容性if (!patch.compatibility.includes(currentVersion)) {throw new Error('Incompatible patch');}// 应用补丁await this.applyPatchFile(patch);// 验证更新结果await this.verifyUpdate(patch.version);return true;} catch (error) {console.error('Patch application failed:', error);return false;}}
}
