一次React-Webpack极简开发环境搭建

比如一个极简的todoList

选择一个好的根目录

一个好的根目录

初始化包

• 敲入初始化命令: npm init, 输入一些关于包的信息
• 在根目录下得到包文件package.json

你的package.json也许是这样

{
  "name": "todos",
  "version": "1.0.0",
  "description": "a tiny todos list App.",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "Heskey Baozi",
  "license": "MIT"
}

加载依赖项

React.JS - "A JavaScript library for building user interfaces"

• React: npm install react --save
• ReactDOM: npm install react-dom --save

或者连在一起写: npm install react react-dom --save

Babel - "Use next generation JavaScript, today.

• Babel:npm install babel --save

Webpack - "A module bundler"

• Webpack: npm install webpack --save-dev

加载完这些后

你的package.json也许是这样

{
  "name": "todos",
  "version": "1.0.0",
  "description": "a tiny todos list App.",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "Heskey Baozi",
  "license": "MIT",
  "dependencies": {
    "babel": "^6.5.2",
    "react": "^15.1.0",
    "react-dom": "^15.1.0"
  },
  "devDependencies": {
    "webpack": "^1.13.1"
  }
}
