This project was bootstrapped with Create React App.
In the project directory, you can run:
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.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
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.
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.
You can learn more in the Create React App documentation.

npm install [email protected] babel-plugin-import --save
原则 1 确保数据类型是值类型 2 如果是引用类型 确保地址不变(对象地址变就不等) ,同时不应当有深层次的变化(嵌套数组 嵌套对象)
组建复合 而非组建继承 composition.js
高阶组件 提高组建复用率 首先想到的就是抽离相同逻辑 在react中就有了HOC (Higer_order_components)的概念, 高阶组件也是一个组建,但是他返回的是另外一个组建,产生新的组建可以对属性进行包装,也可以重写部分生命周期
高阶组件的链式调用 npm install --save-dev babel-plugin-transform-decorators-legacy
config = injectBabelPlugin([ '@babel/plugin-proposal-decorators',{'legacy':true} ],config)
组件通信上下文 vuejs privide & inject 模式的来源 --context
这个模式提供俩个jiaose provider consumer Provider在外层组建 内部需要数据的 就用Consumer来读取
const FormProvider = React.createProvider();
//子组件获取store.xxxnpm install redux --save
Store Reducer Action
