Compatibility caches

From the box this package support https://webcache.googleusercontent.com/ and https://yandexwebcache.net caches for SPA/SSR. If you need more cache types, you always can reassign the cacheList by add cache to any of helpers as second arg.
import { isCacheUrl, defaultCacheUrls } from 'vue-router-webcache';

const additionalCacheUrls = [
  {
    hostname: 'localhost',
    pathname: '/search',
    getRealUrl: (url) => url,
  },
];

const isCache = isCacheUrl(window.location.href, [
  ...defaultCacheUrls,
  ...additionalCacheUrls,
]);

getRealUrl - is optional prop, to extract realUrl for SPA apps or for SSR without vuex-router-sync.
Example of cache

Compatibility Vue

Current package support Vue 2 (vue-router@3) and Vue 3 (vue-router@4).

Nuxt basic usage

  1. Install package
  2. Install @nuxtjs/router
  3. Add vue-router-webcache/nuxt and @nuxtjs/router to nuxt.config.js
  4. Add router.js to .gitignore
export default {
  buildModules: [
    'vue-router-webcache/nuxt',
    ['@nuxtjs/router', {
      keepDefaultRouter: true,
    }],
  ]
};
After first build, package create router.js in root of project nuxt-community/router-module#107
If you change generated router.js, don't forget remove first two lines

By default vue-router-webcache/nuxt use nuxt-vuex-router-sync to get real url
Example in test/fixtures/nuxt

Nuxt advanced usage

If you use custom router or you need more caches, you can customize options or use only helpers without module
export default {
  buildModules: [
    ['vue-router-webcache/nuxt', {
      cacheList: [{
        hostname: '',
        pathname: '',
        getRealUrl: (url) => url,
      }],
      replacePush: true,
      forceVuexRouterSync: false,
      urlGetter: () => '',
    }],
    ['@nuxtjs/router', {
      keepDefaultRouter: true,
    }],
  ]
};
cacheList - list of caches, checks work through URL
replacePush - default @nuxtjs/router replace router.push, you can disable it
urlGetter - function that return fullPath or current real url, serialized by Function.toString, exec in browser
forceVuexRouterSync - option to force add module nuxt-vuex-router-sync and use urlGetter for it. Can be enabled automatically if some of cache's in cacheList hasn't getRealUrl and you don't reassign urlGetter
Default vue-router-webcache/nuxt config
Full example in test/fixtures/nuxt-custom
If you don't change urlGetter, but add some cache without getRealUrl, vue-router-webcache/nuxt add nuxt-vuex-router-sync module to save realUrl in store.state

Vue-router usage

  1. Install package
  2. Create Router by helper
import createRouter from 'vue-router-webcache';

const router = createRouter(routerOptions);

How it work

  • Check if window.location.href is url of some caches
  • Change mode of router to abstract
  • Get real url of cached page
- Nuxt, add nuxt-vuex-router-sync (or analogs) and get window.__NUXT__.state.route.fullPath - Vue, get url from window.location.query for example
  • After Router created, set current route
- Nuxt, mock first router.resolve call patchNuxtRouter - Call router.replace(realUrl)

Api

createRouter

Helper that create vue-router instance with routerOptions, but change mode to abstract and call router.replace if page in caches list

import createRouter from 'vue-router-webcache';

const router = createRouter(routerOptions, [
  {
    hostname: '',
    pathname: '',
    getRealUrl: (url) => url,
  },
]);
routerOptions - simple vue-router options
additionalCacheList - caches that will be added to the defaults (optional)

defaultCacheUrls

Array of default cache urls

import { defaultCacheUrls } from 'vue-router-webcache';

getCache

Get cache by fullUrl

import { getCache } from 'vue-router-webcache';

const cache = getCache(window.location.href, [
  {
    hostname: '',
    pathname: '',
    getRealUrl: (url) => url,
  },
]);

fullUrl - url of checked page
cacheList - list of caches to check (optional)

isCacheUrl

Url checker

import { isCacheUrl } from 'vue-router-webcache';

const isCache = isCacheUrl(window.location.href, [
  {
    hostname: '',
    pathname: '',
  },
]);

fullUrl - url of checked page
cacheList - list of caches to check (optional)

getRealUrl

Helper trying to get realUrl from cached url (use getRealUrl functions from cacheList)

import { getRealUrl } from 'vue-router-webcache';

const realUrl = getRealUrl(window.location.href, [
  {
    hostname: '',
    pathname: '',
    getRealUrl: (url) => url,
  },
]);

fullUrl - url of checked page
cacheList - list of caches to check (optional)

getFullPath

Helper extract fullPath from realUrl and cut base(second argument)

import { getFullPath } from 'vue-router-webcache';

const fullPath = getFullPath('http://example.com/foo/bar', '/foo');
// /bar

fullUrl - url for extracting
base - base url of your app (default=/)

patchNuxtRouter

Router patcher for nuxt, mock first router.resolve

import { patchNuxtRouter } from 'vue-router-webcache';

...

patchNuxtRouter(router, realUrl);

router - instance of vue-router href - real url of current page

Examples

All usage examples you can see in test/fixtures
GH Pages example

URL

Helpers use URL constructor to parse url's. Mb you need install polyfill to use it.
