公司技术会议有人提出把 SPA 网站 API 都换成 protojson 的返回来节省 API 服务器带宽，是不是意义很小？我们后端是 C#和 Node.js，不是 Java 和 Go，开发麻烦，浏览器已经有 gzip 压缩了

@yangg 这个问题的方法有点本末倒置，先看看是什么问题，比如速度慢还是什么，如果是速度慢，应该找到速度慢的具体原因，如果只是减少返回数据的大小，为了加快访问速度，同 20 楼，可以研究下 brotli 以及 brotli static ，可能效果比你用 protojson 好很多。

提建议的人应该主动给公司算一下能省多少带宽费用。老板决定值不值得。

这是拍脑袋还是用数据评估的，比如现在 api 使用了多少带宽，使用 xxx 后能减少多少带宽，另外，在这里节省大概率会在其他地方找补

@julyclyde #17 ，现在有 nextjs 了，更流行前端转全栈了。

启用 gzip 已经足够了，完全没必要改
