优化博客访问速度

Jsdelivr是一个很好用的CDN服务商，由一些不知名的原因，jsdelivr在国内的备案被取消了，所以导致博客时不时抽风，这里记录以下next主题更换cdn

---

NexT在8.9.0版本增加了对于自定义CDN的选项，我们根据文档提示，我们需要在主题配置文件下的vendors.custom_cdn_url下添加cdn链接，如下

初始配置:
vendors:
  # The CDN provider of NexT internal scripts.
  # Available values: local | jsdelivr | unpkg | cdnjs | custom
  # Warning: If you are using the latest master branch of NexT, please set `internal: local`
  internal: local
  # The default CDN provider of third-party plugins.
  # Available values: local | jsdelivr | unpkg | cdnjs | custom
  # Dependencies for `plugins: local`: https://github.com/next-theme/plugins
  plugins: jsdelivr
  # Custom CDN URL
  # For example:
  # custom_cdn_url: https://cdn.jsdelivr.net/npm/${npm_name}@${version}/${minified}
  # custom_cdn_url: https://cdnjs.cloudflare.com/ajax/libs/${cdnjs_name}/${version}/${cdnjs_file}
  custom_cdn_url:

我们只需要将下面代码替换初始配置代码即可

vendors:
  # The CDN provider of NexT internal scripts.
  # Available values: local | jsdelivr | unpkg | cdnjs | custom
  # Warning: If you are using the latest master branch of NexT, please set `internal: local`
  internal: local
  # The default CDN provider of third-party plugins.
  # Available values: local | jsdelivr | unpkg | cdnjs | custom
  # Dependencies for `plugins: local`: https://github.com/next-theme/plugins
  plugins: unpkg
  # Custom CDN URL
  # For example:
  # custom_cdn_url: https://cdn.jsdelivr.net/npm/${npm_name}@${version}/${minified}
  # custom_cdn_url: https://cdnjs.cloudflare.com/ajax/libs/${cdnjs_name}/${version}/${cdnjs_file}
