@feasy/nuxt-page-cache v1.5.5

nuxt-page-cache

Cache middleware for nuxt's page rendering.

Setup

npm install @feasy/nuxt-page-cache

or

yarn add @feasy/nuxt-page-cache

then inside your nuxt.config.js add cache config:

module.exports = {
  // If you provide a version, it will be stored inside cache.
  // Later when you deploy a new version, old cache will be
  // automatically purged.
  version: pkg.version,

  // ....

  modules: [
      '@feasy/nuxt-page-cache',{
    // if you're serving multiple host names (with differing
    // results) from the same server, set this option to true.
    // (cache keys will be prefixed by your host name)
    // if your server is behind a reverse-proxy, please use
    // express or whatever else that uses 'X-Forwarded-Host'
    // header field to provide req.hostname (actual host name)
    useHostPrefix: false,
    pages: [
      // these are prefixes of pages that need to be cached
      // if you want to cache all pages, just include '/'
      '/page1',
      '/page2',

      // you can also pass a regular expression to test a path
      /^\/page3\/\d+$/,

      // to cache only root route, use a regular expression
      /^\/$/
    ],
    
    key(route, context) {
      // custom function to return cache key, when used previous
      // properties (useHostPrefix, pages) are ignored. return 
      // falsy value to bypass the cache
    },

    store: {
      type: 'memory',

      // maximum number of pages to store in memory
      // if limit is reached, least recently used page
      // is removed.
      max: 100,

      // number of seconds to store this page in cache
      ttl: 60,
    },
  },
  ],

  // ...
};

If you want to make cache for different users this is a demo

  modules: [
    '@feasy/nuxt-page-cache',{
    useHostPrefix: false,
    pages: [
      '/page1',
      '/page2',
    ],
    key(route, context) {
      if (route === '/') {
        const hostname =
          (context.req && context.req.hostname) ||
          (context.req && context.req.host) ||
          (context.req && context.req.headers && context.req.headers.host) ||
          (context.req && context.req.headers && context.req.headers.hostname)
        const parseCookie = str =>
          str
            .split(';')
            .map(v => v.split('='))
            .reduce((acc, v) => {
              acc[decodeURIComponent(v[0].trim())] = decodeURIComponent(v[1].trim())
              return acc
            }, {})
        const cookie = context.req.headers && context.req.headers.cookie && parseCookie(context.req.headers.cookie)
        if (cookie && cookie.username) {
          return `${hostname}${route}.${cookie.username}`
        }
      }
    },
    store: {
      type: 'memory',
      // maximum number of pages to store in memory
      // if limit is reached, least recently used page
      // is removed.
      max: 100,
      // number of seconds to store this page in cache
      ttl: 60,
    },
  },
