基于react-create-app和nodejs搭建项目

"scripts": {
    "build-css": "node-sass-chokidar src/assets/sass -o src/assets/css",
    "watch-css": "npm run build-css && node-sass-chokidar src/assets/sass -o src/assets/css --watch --recursive",
    "start-js": "react-scripts start",
    "start": "npm-run-all -p watch-css start-js",
    "build-js": "react-scripts build",
    "build": "npm-run-all build-css build-js",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },

配置方法

配置代理到node层

"proxy": {
    "/api": {
      "target": "http://localhost:4222/"
    }
  }

使用

node层配置：

app.use(‘/api/productSve‘, productSve);

router.get(‘/getProducts‘, function (req, res) {
  var results = {
    id : 1,
    title : ‘电脑‘,
    price : 5000,
  }
  res.json(results);
});

react中使用：

componentDidMount() {
  fetch(‘/api/productSve/getProducts‘)
    .then(res => {
      res.json()
    })
    .then(data => {
      console.log(data)
    })
    .catch(err => {
      console.log(err)
    })
}
