"前端依赖版本策略与安全升级流程"

前端依赖版本策略与安全升级流程概述前端依赖更新需在风险与稳定性之间权衡。通过锁定、审计与自动化流程可实现安全与可追溯升级。锁定与来源使用 `package-lock.json`/`pnpm-lock.yaml`/`yarn.lock` 锁定版本与来源仅允许来自官方注册表与企业镜像的依赖SemVer与升级矩阵type SemVer = { major: number; minor: number; patch: number } function parseSemver(v: string): SemVer { const [major, minor, patch] = v.replace(/^v/, '').split('.').map(n => Number(n)) return { major, minor, patch } } function isSafeMinorUpgrade(cur: string, next: string): boolean { const a = parseSemver(cur), b = parseSemver(next) return a.major === b.major && (b.minor > a.minor || (b.minor === a.minor && b.patch >= a.patch)) } 安全公告与审计订阅CVE与供应商公告，建立高危组件清单在CI运行依赖审计并生成许可证与风险报告自动化PR与回滚type UpgradePlan = { name: string; from: string; to: string; risk: 'low' | 'medium' | 'high' } function buildUpgradePlan(name: string, from: string, to: string): UpgradePlan { const safe = isSafeMinorUpgrade(from, to) return { name, from, to, risk: safe ? 'low' : 'medium' } } 运维要点建立定期升级节奏与灰度发布策略对高风险升级提供快速回滚与错误预算管理记录升级审计与差异SBOM以支持追溯以上流程可在保持稳定性的同时，达成前端依赖的安全与可追溯升级。
