我应该什么时候运行“react-native start"? [英] When should I run `react-native start`?

问题描述

刚开始使用 React-Native(对于非 CRNA/Expo 案例)，阅读 react-native 文档 或 了解 CLI 何时适合运行 react-native start

Just getting started with React-Native (for the non-CRNA/Expo case) and it's not clear to me after reading the react-native docs or Understanding the CLI when it's appropriate to run react-native start

react-native start --help 只是说启动网络服务器.运行 react-native run-ios 也会启动相同的服务器，但它实际上也在模拟器中运行它.

react-native start --help simply says starts the webserver. Running react-native run-ios also starts the same server except it also actually runs it in the simulator.

问题:什么时候运行 react-native start 与直接运行模拟器(即 react-native run-ios)比较合适>)?

Question: When is it appropriate to run react-native start vs. just running the simulators directly (i.e. react-native run-ios)?

推荐答案

react-native start 和 npm start 一样，就像你说的启动 react 打包器/服务器.

react-native start is same as npm start and like you said it's to start the react packager/server.

我发现自己不得不使用 npm start 显式停止和启动服务器.

I have found myself in situations where I had to stop and start the server explicitly using npm start.

要启动一个项目，您可以使用 react-native run-ios 并且它会同时启动模拟器和服务器，但如果应用程序已安装并且您想重新启动服务器，您可以在终端中明确停止它并使用 react-native start 或 npm start 重新启动它.

To start up a project, you use the react-native run-ios and it starts up both the simulator and the server but in cases where the app has been installed and you want to restart the server, you can stop it explicitly in the terminal and use react-native start or npm start to start it up again.
