webpack算是使用程序员使用最多的打包工具，面试中往往会问到webpack的相关问题，而rollup被问到的要少很多。导致这种现象的一个原因是，「应用开发使用webpack，库开发使用rollup」的说法。

但是两个打包工具都有很强大的插件开发功能，功能差异越来越模糊，但是rollup使用起来更加简洁，而且能打出能小体积的文件。但当我们做前端应用时，性能分析往往要求更小的库，所以rollup更符合开发库的要求。

这次算是一个打包的实验，我们使用两个工具都对这个项目打一次包。

优： 输出结果更扁平 自动移除未引用代码 打包结果依然完全可读

缺： 加载非ESM第三方模块比较复杂 模块最终都被打包到一个函数中，无法实现HMR（热替换） 浏览器环境中，代码拆分功能依赖AMD库

开发应用 webpack 更全更常见 开发框架类库 rollup 这里由于是组件库，优点很有用，缺点可以忽略不计，所以用了rollup

Getting Started with Create React App

This project was bootstrapped with Create React App.

Available Scripts

In the project directory, you can run:

yarn start

Runs the app in the development mode.\ Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.\ You will also see any lint errors in the console.

yarn test

Launches the test runner in the interactive watch mode.\ See the section about running tests for more information.

yarn build

Builds the app for production to the build folder.\ It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.\ Your app is ready to be deployed!

See the section about deployment for more information.

yarn eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
