Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

  • 🔧 灵活配置: 支持多种配置方式和自定义策略
  • 💪 TypeScript: 完整的 TypeScript 支持
  • 🎨 组合式API: 提供 useCacheRouter 组合函数
  • 🔍 调试友好: 内置调试模式和状态可视化

📦 安装

npm install vue-router-cache-plugin
# 或
yarn add vue-router-cache-plugin
# 或
pnpm add vue-router-cache-plugin

🚀 快速开始

1. 基本用法(推荐)

import { createRouter, createWebHistory } from 'vue-router'
import { createRouterCachePlugin } from 'vue-router-cache-plugin'

const router = createRouter({
  history: createWebHistory(),
  routes: [
    {
      path: '/products',
      name: 'ProductList',
      component: () => import('./views/ProductList.vue')
    },
    {
      path: '/products/:id',
      name: 'ProductDetail',
      component: () => import('./views/ProductDetail.vue')
    }
  ]
})

// 创建并安装缓存插件
const cachePlugin = createRouterCachePlugin({
  cacheMap: {
    'ProductList': ['ProductDetail'] // 从商品列表进入详情时缓存列表页
  },
  debug: true, // 开发模式下启用调试
  maxCacheSize: 10 // 最大缓存页面数
})

// 安装插件到路由实例
cachePlugin(router)

export default router

2. 在模板中使用

<template>
  <div id="app">
    <!-- 使用缓存路由视图 -->
    <CacheRouterView />
  </div>
</template>

<script setup>
import { CacheRouterView } from 'vue-router-cache-plugin'
</script>

3. 使用组合函数

<script setup>
import { useCacheRouter } from 'vue-router-cache-plugin'

const {
  cacheList,      // 当前缓存列表
  isCached,       // 当前页面是否被缓存
  addCache,       // 添加缓存
  removeCache,    // 移除缓存
  clearCache      // 清空缓存
} = useCacheRouter()

// 手动缓存当前页面
const handleCacheCurrentPage = () => {
  addCache()
}

// 清空所有缓存
const handleClearAll = () => {
  clearCache()
}
</script>

<template>
  <div>
    <p>当前页面缓存状态: {{ isCached ? '已缓存' : '未缓存' }}</p>
    <p>缓存列表: {{ cacheList.join(', ') }}</p>
    
    <button @click="handleCacheCurrentPage">缓存当前页面</button>
    <button @click="handleClearAll">清空所有缓存</button>
  </div>
</template>

📖 详细配置

插件选项

interface RouterCachePluginOptions {
  /** 缓存映射关系 */
  cacheMap?: Record<string, string[]>
  
  /** 是否开启调试模式 */
  debug?: boolean
  
  /** 最大缓存数量 */
  maxCacheSize?: number
  
  /** 自定义缓存策略 */
  customStrategy?: (to: RouteLocationNormalized, from: RouteLocationNormalized) => boolean
}

路由元信息配置

const routes = [
  {
    path: '/products',
    name: 'ProductList',
    component: ProductList,
    meta: {
      cache: true,                    // 启用缓存
      cacheTargets: ['ProductDetail'] // 缓存目标路由
    }
  },
  {
    path: '/settings',
    name: 'Settings',
    component: Settings,
    meta: {
      noCache: true // 禁用缓存
    }
  }
]

组件配置

<template>
  <!-- 基本用法 -->
  <CacheRouterView />
  
  <!-- 高级配置 -->
  <CacheRouterView 
    :max="5"
    :include="['CustomPage']"
    :exclude="['NoCache']"
  />
  
  <!-- 简化版本 -->
  <SimpleCacheRouterView />
</template>

🎯 使用场景

1. 列表-详情页缓存

// 配置:从列表进入详情时缓存列表页
cacheMap: {
  'ProductList': ['ProductDetail'],
  'UserList': ['UserDetail', 'UserEdit']
}

2. 表单页面缓存

// 配置:编辑页面返回时保持表单状态
cacheMap: {
  'UserEdit': ['UserProfile']
}

3. 自定义缓存策略

createRouterCachePlugin({
  customStrategy: (to, from) => {
    // 自定义逻辑:只有在特定条件下才缓存
    return from.query.cache === 'true'
  }
})

🔧 API 参考

useCacheRouter()

const {
  // 状态
  cacheList,          // 当前缓存列表(只读)
  isCached,           // 当前页面是否被缓存
  cacheStats,         // 缓存统计信息
  
  // 基本操作
  addCache,           // 添加缓存
  removeCache,        // 移除缓存
  clearCache,         // 清空所有缓存
  hasCache,           // 检查是否缓存
  
  // 便捷操作
  cacheCurrentPage,   // 缓存当前页面
  removeCacheCurrentPage, // 移除当前页面缓存
  
  // 批量操作
  batchAddCache,      // 批量添加缓存
  batchRemoveCache,   // 批量移除缓存
  
  // 高级用法
  getCacheStore       // 获取缓存存储实例
} = useCacheRouter()

Router 扩展方法

// 插件会为 router 实例添加以下方法
router.addCache('PageName')     // 添加缓存
router.removeCache('PageName')  // 移除缓存
router.clearCache()             // 清空缓存
router.getCacheList()           // 获取缓存列表

🐛 调试

启用调试模式:

createRouterCachePlugin({
  debug: true
})

调试模式下会:

  • 在控制台输出详细的缓存操作日志
  • 将缓存存储实例暴露到 window.__ROUTER_CACHE_STORE__
  • 提供缓存统计信息

🔄 迁移指南

从 Vue 2 版本迁移

// Vue 2 版本
Vue.use(DynamicRouterView, { router, cacheMap })

// Vue 3 版本(正确方式)
const cachePlugin = createRouterCachePlugin({ cacheMap })
cachePlugin(router)

// 在 main.js 中
import { createApp } from 'vue'
import router from './router'

const app = createApp(App)
app.use(router) // 这里使用 app.use()
app.mount('#app')
