套娃 + 1

Spring 也在搞 GraalVM，这些东西编译时间都太长了

加 1000 上 U2720QM

4K 就没有 27 以下的吧

@loveuqian 这不是 Keychron 的，虽说据说是同厂代工

@Joker123456789 每次请求之前都会做一次 OPTIONS 请求（ preflight ），返回 200 才会执行实际的请求。连 OPTIONS 都没实现，怎么执行实际请求？

我直接在业务服务器上 ping 数据库的域名,延迟很低, 说明直接通过内网访问的

延迟低怎么就得出“直接通过内网访问的”这个结论的？

直接 proxy_pass

nginx -> gateway -> api，降级、熔断

我是这么玩的。

Hikari 不香吗？用什么 Druid ？

我这个 TS 吹就很尴尬

那为什么不用 Hutool ？

杠一下，这并不 RESTful 。

TS 好评

gRPC is a modern open source high performance RPC framework that can run in any environment.

let product of products 不是 TypeScript 的特性吗？ products 不就是 Product[] 类型吗？遍历出来不就是 Product 类型吗？

@sunny352787 以前的事情啦，现在应该没有了。
