如何检测我是否在 next.js 中的客户端服务器上? [英] How do I detect whether I am on server on client in next.js?

问题描述

我正在使用带有 Next.js 的客户快递服务器.它在容器中运行.我正在使用 isomorphic-fetch 执行 http 请求以获取渲染数据.我想做 localhost 在服务器上运行时和 mysite.com 在客户端上运行时.不确定实现这一目标的最佳方法.我可以通过 const isServer = typeof window === 'undefined' 来做这件事，但这似乎很糟糕.

I am using a customer express server with Next.js. It's running within a container. I am doing an http request with isomorphic-fetch to get data for my render. I'd like to do localhost when running on server and mysite.com when running on client. Not sure the best way to accomplish this. I can do it hackily by doing const isServer = typeof window === 'undefined' but that seems pretty bad.

推荐答案

现在(2020 年 1 月)应该是 typeof window === 'undefined' 因为 process.browser 已弃用

Now (2020 Jan) it should be typeof window === 'undefined' since process.browser is deprecated
