老卫Vibe coding进展.20260727 1、做了一个简单的监控网站,自用为主,监测我自己开发的网站的流量和下单来源,目前够用了 2、做了一个【老卫自媒体核心群】课程社区 - 支持注册、支付、阅读内容,还可以听音频,支持后台更新文章,文章格式默认markdown 3、做了一个【老卫的Vibe coding社区】- 支持注册、支付、阅读等 至此,老卫面向大众的课程相关的内容全部搬到了自己托管的网站上去了,技术栈如下: 前端:React + Vite 后端:Cloudflare + Workers 数据库:Cloudflare D1 存储:Cloudflare R2 邮件推送:Resend 这一切都不是要钱,老卫只买了个域名,10美金/年。(约 ¥67.78) 后续计划如下: 1、录制老卫Vibe coding相关课程,这个拖了比较久了,最近一直在vibe coding 2、模块化最近写的一些网站,争取做一份通用的代码出来,方便后续别的产品的上线 3、对接支付,目前计划对接Stripe, 对于支付老卫还是比较慎重,所以估计要一月以后了 关于Vibe coding,老卫的一些观点 Vibe coding极大的降低了编程门槛,大家多去烧token 十万美金以下的编码,AI都能搞定,多去像创意,把交易流程走通,剩下的就是搞流量和卖了 不要浪费时间去讨论哪个大模型好,这是极端浪费时间的事情,哪个好就用哪个,剩下的就是干就完了 最后宣传一下老卫的两个社群 - 自媒体核心群、Vibe coding社群,需要加入的私信老卫小号 - xiaowei6571
