ReactNative Eject 解释 [英] ReactNative Eject Explained

问题描述

我真的在一小时前开始阅读 ReactNative 并且正在阅读这个 git readme https://github.com/react-community/create-react-native-app/blob/master/react-native-scripts/template/README.md

I literally started reading about ReactNative an hour ago and am reading this git readme https://github.com/react-community/create-react-native-app/blob/master/react-native-scripts/template/README.md

接下来我用谷歌搜索了它，发现这个链接似乎在解释它，但对我来说不是网络、反应或反应原生的新手https://github.com/react-community/create-react-native-app/blob/master/EJECTING.md

Next I googled about it and found this link which seem to be explaining it but not to me novice in web, react, or react-native https://github.com/react-community/create-react-native-app/blob/master/EJECTING.md

有人可以像我2岁一样向我解释eject是什么意思吗?我一直听到被驱逐的项目"这个词，但我无法理解它.

Can someone explain to me as if I am 2 years old what is the meaning of eject? I keep hearing term "ejected project" but I cannot wrap my head around it.

推荐答案

总结

如果您使用 create-react-native-app MyApp 创建了一个应用程序，弹出您的应用程序将使您的应用程序与您使用 react-native init MyApp 创建您的项目相同

Summary

If you created an app using create-react-native-app MyApp, ejecting your app gets your app to be the same as if you created your project using react-native init MyApp

又名

create-react-native-app MyApp > 更改应用程序 > 弹出应用程序

create-react-native-app MyApp > make changes to app > eject app

大致相当于

react-native init MyApp > 修改应用程序

create-react-native-app MyApp 和 react-native init MyApp 有什么区别?

create-react-native-app 背后的理念是:

The philosophy behind create-react-native-app is:

• 最短的Hello World 时间":创建 React Native App 应该将尝试构建移动应用程序所需的设置时间减少到绝对最短，理想情况下与 React Web 开发相当(尤其是作为见 Create React App).
• 在您的设备上开发:当您想要测试您的应用对输入的感受和响应时，在物理设备上开发应该很容易.
• 一个构建工具:如果您只是想开始使用 React Native，则不需要安装 Xcode、Android Studio、NDK 或弄乱环境变量.
• 无锁定:如果您需要编写自定义本机代码或修改应用的构建方式，您可以随时弹出"到您自己的构建设置.

• Minimal "Time to Hello World": Create React Native App should reduce the setup time it takes to try building a mobile app to the absolute minimum, ideally on par with React web development (especially as seen with Create React App).
• Develop on Your Device: It should be easy to develop on a physical device when you want to test how your app feels and responds to inputs.
• One Build Tool: If you just want to get started with React Native, you shouldn't need to install Xcode, Android Studio, NDKs, or mess with environment variables.
• No Lock-In: You can always "eject" to your own build setup if you need to write custom native code or modify how your app is built.

本质上，create-react-native-app 可让您快速启动并运行而无需进行大量(或任何)配置.为了做到这一点，它对你隐藏了很多细节.

Essentially, create-react-native-app lets you get up and running quickly without having to a do a lot of (or any) configuration. In order to do this, it hides a lot of details from you.

如果你想创建一个严肃的应用程序，你需要设置一个真正的开发环境.您可以通过运行 react-native init 从头开始​​执行此操作.如果您从使用 create-react-native-app 的 React Native 项目开始，您可以通过弹出"您的应用程序来达到同样的目的

If you want to create a serious app, you need to set up a real development environment. You can do this from scratch by running react-native init <project-name>. If you started with a react native project using create-react-native-app, you can get to this same place by "ejecting" your app
