 1 | # v-keep-alive-chain
 2 | vue缓存链控制，Vue前进刷新，后退不刷新（Forward refresh, back not refresh）
 3 | 
 4 | [online demo](https://dongj0316.github.io/keep-alive-chain/demo/)
 5 | 
 6 | ## Installation
 7 | 
 8 | ## Use
 9 | 
10 | ```bash
11 | $ npm install v-keep-alive-chain
12 | ```
13 | 
14 | ```js
15 | // main.js
16 | import { mergeBeforeEachHook, VKeepAliveChain } from 'v-keep-alive-chain'
17 | 
18 | Vue.use(VKeepAliveChain, {
19 |   key: 'cacheTo' // 可选的 默认为cacheTo
20 | })
21 | 
22 | // 如果你没有注册过beforeEach
23 | router.beforeEach(mergeBeforeEachHook())
24 | 
25 | // 如果有注册beforeEach
26 | router.beforeEach(mergeBeforeEachHook((to, from, next) => {
27 |   next()
28 | }))
29 | ```
30 | 
31 | 然后在App.vue（视你的情况而定）中
32 | 
33 | ```html
34 | <keep-alive>
35 |   <router-view v-if="$route.meta.keepAlive"/>
36 | </keep-alive>
37 | <VKeepAliveChain>
38 |   <router-view v-if="!$route.meta.keepAlive"/>
39 | </VKeepAliveChain>
40 | ```
41 | 
42 | 接着在router中配置你的需求
43 | 
44 | ```js
45 | [
46 |   {
47 |     path: '/list',
48 |     name: 'list',
49 |     meta: {
50 |       cacheTo: ['info']
51 |     }
52 |     // ...
53 |   },
54 |   {
55 |     path: '/info',
56 |     name: 'info',
57 |     // ...
58 |   }
59 | ]
60 | ```
61 | 
62 | 然后就能愉快的玩耍了
63 | 
64 | ## Local setup
65 | 
66 | ```
67 | npm install
68 | npm run serve
69 | ```
