部署在CF的轻量化导航页面,可移动卡片式书签,方便管理
github项目

Card-Tab 书签卡片式管理,进入管理模式可以自由移动书签位置,添加和删除书签,支持自定义网站分类,支持切换黑暗色主题
一、cloudflare workes部署
新版本部署
2024.10.30 更新:
1)、增加了前端验证,并取消了在浏览器中保存日志。现在超过15分钟需重新登录,及时退出登录能让你的隐私更安全;
2)、进入设置之前会在自动备份书签,KV里将保存最近10次的备份;
3)、小幅更改了配色。

二、添加变量
1、先建立一个kv空间,名字为: CARD_ORDER ,再在 变量-KV 命名空间绑定 刚才建立的kv空间。

2、变量-环境变量 中添加 ADMIN_PASSWORD ,值是你的后台管理员密码

3、有域名的可邦定域名,完成。
