Firebase托管:部署时缓存清除脚本 [英] Firebase Hosting: cache busting scripts on deploy

问题描述

我在firebase上托管了Polymer(单页应用)应用程序.当我将新版本部署到Firebase时，我希望Firebase重新加载javascript源而不是使用缓存的源.是否有可能通过firebase.json做到这一点?如果是这样，怎么办?还是我必须手动将缓存清除网址添加到我的生成输出中?谢谢

I have a Polymer (single page app) application hosted on firebase. When I deploy a new version to firebase, I'll like firebase to reload the javascript source instead of using cached ones. Is it possible to do that via firebase.json? If so, how? Or do i have to manually add a cache busting url to my build output? Thanks

推荐答案

向您的版本中添加Webpack或类似工具可能是最简单的方法，因为目前尚无一种方法可以直接使用Firebase直接达到所需的结果:

Adding Webpack or a similar tool to your build is probably the easiest way to go, as there's not currently a way to achieve the desired result with Firebase directly:

如何使Webpack使用缓存-后缀无效吗?

如果可以完全删除缓存，则可以为不想缓存在firebase.json中的文件设置相关标头:

If you're okay removing the cache completely, you can simply set the related headers for the files you don't want cached in firebase.json:

{
  ...
  "headers": [{
      "source": "build.js",
      "headers": [{
        "key": "Cache-Control",
        "value": "max-age=0"
      }]
  }],
  ...
}
