PWA 实现
Purpose
让 Web 应用具备可安装、离线兜底和可控更新能力。
Procedure
- 确认 PWA 是否值得做：面向移动端/桌面安装、弱网离线、重复访问场景时优先；纯内部后台、强实时流媒体或只需要普通缓存时不要强行 PWA。
- 先补齐 manifest、图标、主题色和 HTML 引用；图标至少覆盖 192/512，Android 需 maskable，iOS 需 apple touch icon。
- 注册 Service Worker，并设计更新提示；不要静默
skipWaiting()后强刷用户页面。 - 用 Workbox 或框架插件管理 precache/runtime cache；登录、支付、权限变更等敏感请求必须走网络。
- 提供 offline fallback 页面和安装提示 UI，并验证首次加载、离线访问、更新激活、卸载重装。
Detailed References
- Load references/manifest-and-icons.md for manifest fields, HTML links, icon requirements, screenshots, and iOS notes.
- Load references/service-worker-workbox.md for Service Worker registration, Workbox strategies, Vite integration, offline fallback, and update flow.
Constraints
- Service Worker 仅在 HTTPS 下工作（localhost 除外）。
- 缓存策略必须区分页面、静态资源、API 与敏感操作；不要把登录、支付、权限接口缓存起来。
- Service Worker 更新有生命周期延迟；用户可见刷新提示优先于强制刷新。
- iOS PWA 能力弱于 Android，安装、推送和生命周期都要单独验证。
- 缓存有配额和逐出机制，必须设置 max entries / max age。
Expected Output
产出可安装的 Web 应用、离线 fallback、可见更新提示和明确缓存策略。验证 Lighthouse PWA、DevTools Application 面板、离线模式、更新发布和移动端安装流程。
Usage Guidance
Before installing, note that this skill is intended to help an agent make PWA changes in your web app, including service worker and caching behavior. Review generated code carefully so sensitive routes and authenticated actions remain network-only.
Capability Assessment
Purpose & Capability
The skill’s purpose is to guide implementation and review of PWA features such as manifests, service workers, Workbox caching, offline fallback, and update prompts; the artifacts match that purpose.
Instruction Scope
Instructions are scoped to user-directed frontend implementation and include appropriate safety boundaries, such as not caching login, payment, permission, or write operations and avoiding silent forced refreshes.
Install Mechanism
The package contains markdown and JSON only; package.json declares metadata but no scripts, dependencies, or install-time execution.
Credentials
The guidance may lead an agent to modify web app files for PWA behavior, which is proportionate to the stated implementation purpose and not automatic.
Persistence & Privilege
No persistence, background worker, credential access, local indexing, or privilege escalation is introduced by the skill itself; service worker persistence is discussed as the normal subject of PWA implementation.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install fec-pwa-implementation - After installation, invoke the skill by name or use
/fec-pwa-implementation - Provide required inputs per the skill's parameter spec and get structured output
Version History
v2.5.1
- Added LICENSE file to the project for clarity on usage and distribution terms.
- No changes to documentation or skill instructions.
v2.5.0
- Added detailed documentation in SKILL.md outlining PWA implementation purpose, step-by-step procedure, constraints, and expected outputs.
- Clarified correct use cases for PWA, distinguishing them from regular caching or non-installable performance enhancements.
- Included references to supporting documents for manifest setup, Service Worker strategies, and offline handling.
- Emphasized security requirements, update prompting best practices, and platform-specific limitations (especially iOS).
- Provided validation criteria for PWA features using Lighthouse, DevTools, and installation flows.
