我是使用React和Redux的新手,我正在构建一个简单的todos应用程序.我正在使用命令行中的create-react-app工具编写我的应用程序.

问题

我去了其他博客和帖子,其他人提到我错过了一个npm插件来转换装饰器“transform-decorators-legacy”,我将这个添加到我的依赖项和Babel,但我仍然收到相同的错误.

Syntax error: Unexpected token (9:0)

   7 | import './App.css';
   8 |
>  9 | @connect((store) => {
     | ^
  10 |   return {
  11 |     user: store.user.user
  12 |   }

我的代码

import React,{ Component } from 'react';
import { connect } from 'react-redux';

import Todos from './components/Todos';
import Todo from './components/Todo';

import './App.css';

@connect((store) => {
  return {
    user: store.user.user
  }
})
class App extends Component {
  constructor(){
    super()
    this.state = {
      name: 'Brad',todos: [
        {
          id: '001',name: 'Take out trash',completed: false
        },{
          id: '002',name: 'Meeting with boss',{
          id: '003',name: 'Go out to dinner',completed: false
        }
      ]
    }
  }
  render() {
    return (
      <div className="App">
        <h1>Hello</h1>
        <Todos name={this.state.name} todos={this.state.todos}/>
        <Todo/>
      </div>
    );
  }
}

export default App;

我的依赖

的package.json

{
  "name": "react-redux-project","version": "0.1.0","private": true,"dependencies": {
    "axios": "^0.16.2","react": "^15.6.1","react-dom": "^15.6.1","react-redux": "^5.0.6","redux": "^3.7.2","redux-logger": "^3.0.6","redux-promise-middleware": "^4.3.0","redux-thunk": "^2.2.0"
  },"devDependencies": {
    "babel": "^6.23.0","babel-plugin-transform-decorators-legacy": "^1.3.4","react-scripts": "1.0.11"
  },"scripts": {
    "start": "react-scripts start","build": "react-scripts build","test": "react-scripts test --env=jsdom","eject": "react-scripts eject"
  }
}

任何帮助/知识将不胜感激！

解决方法

试试这样：

const stateMap = (state) => {
    console.log('state',state);
    return {
        //something from state
    };
};

export default connect(stateMap)(App);
