如何搭建react项目

 

手工搭建

npm init -y 初始化package.json

配置webpack.config.js

 

需要安装的

{
  "name": "byme",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "dev": "webpack-dev-server --open --port 8888",
    "dev-slider": "webpack-dev-server --open --port 8888 --config webpack.config.slider.js"//用其他文件打包
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.2",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "babel-preset-stage-0": "^6.24.1",
    "css-loader": "^0.28.7",
    "file-loader": "^1.1.5",
    "html-webpack-plugin": "^2.30.1",
    "less": "^2.7.3",
    "less-loader": "^4.0.5",
    "style-loader": "^0.19.0",
    "url-loader": "^0.6.2",
    "webpack": "^3.8.1",
    "webpack-dev-server": "^2.9.4"
  },
  "dependencies": {
    "react": "^16.0.0",
    "react-dom": "^16.0.0"
  }
}

babelrc:

{
  "presets": ["es2015","stage-0","react"

  ]

}

 react需要react转译器

 

安装脚手架
npm install -g create-react-app(项目名)
create-react-app my-app

cd my-app
npm start

安装搭建好的项目,使用内置的webpack打包

在src下建index.jsx文件
该脚手架安装额外的插件需要用yarn add 命令，用npm install会覆盖已经安装的模块
