我使用创建了我的应用npx create-nuxt-app
,然后添加了npm install @nuxtjs/pwa --save
。我在index.html中加入了Google字体,其中包括:
<link href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700|Material+Icons" rel="stylesheet" data-n-head="true">
通过在devtools /应用程序标签中点击“离线”复选框,然后重新加载,我在Chrome中以离线模式测试了我的应用程序。除字体外,所有内容均被缓存。
然后我添加:
workbox: {
runtimeCaching: [
{
urlPattern: 'https://fonts.googleapis.com/.*',
handler: 'cacheFirst',
method: 'GET'
},
]
}
到nuxt.config.js
文件,但我无法缓存字体。我在urlPattern上尝试了多种变体。
Nuxt正在为我生成一个服务工作者,它看起来像这样:
importScripts('/_nuxt/workbox.3de3418b.js')
const workboxSW = new self.WorkboxSW({
"cacheId": "my-app",
"clientsClaim": true,
"directoryIndex": "/"
})
workboxSW.precache([
{
"url": "/_nuxt/app.bb74329360a7ee70c2af.js",
"revision": "8477c51cbf9d3188f34f1d61ec1ae6bc"
},
{
"url": "/_nuxt/layouts/default.ce9446c7c3fffa50cfd2.js",
"revision": "504d33b2d46614e60d919e01ec59bbc8"
},
{
"url": "/_nuxt/manifest.912c22076a54259e047d.js",
"revision": "a51a74b56987961c8d34afdcf4efa85c"
},
{
"url": "/_nuxt/pages/index.6bfd6741c6dfd79fd94d.js",
"revision": "1a80379a5d35d5d4084d4c2b85e1ee10"
},
{
"url": "/_nuxt/vendor.f681eb653617896fcd64.js",
"revision": "59c58901fd5142fdaac57cbee8c1aeb4"
}
])
workboxSW.router.registerRoute(new RegExp('/_nuxt/.*'), workboxSW.strategies.cacheFirst({}), 'GET')
workboxSW.router.registerRoute(new RegExp('/.*'), workboxSW.strategies.networkFirst({}), 'GET')
workboxSW.router.registerRoute(new RegExp('https://fonts.googleapis.com/.*'), workboxSW.strategies.cacheFirst({}), 'GET')
为什么字体没有被缓存?
编辑#1:感谢Jeff Posnick,我了解发生了什么。我还没有找到正确的语法来传递nuxt.config.js
文件,但是作为一个实验,我sw.js
直接修改了文件并添加了以下两行:
workboxSW.router.registerRoute(new RegExp('https://fonts.googleapis.com/.*'),
workboxSW.strategies.cacheFirst({cacheableResponse: {statuses: [0, 200]}}),
'GET')
workboxSW.router.registerRoute(new RegExp('https://fonts.gstatic.com/.*'),
workboxSW.strategies.cacheFirst({cacheableResponse: {statuses: [0, 200]}}),
'GET')
可行!
