React-redux將HOC連接為類裝飾器@connect

Question

我有一個組件使用ES +建議的deco-redux連接HOC的裝飾器語法形式包裝：

import React, { Component } from 'react';
import { connect } from 'react-redux';
import RegisterForm from './register-form';
import { registerUser } from '../store/api/Auth/actions';

@connect(null, { registerUser: registerUser })
export default class RegisterPage extends Component {
  handleSubmit = values =>
    this.props.registerUser(values);

  render() {
    return (
      <div>
        <h1>Register Here</h1>
        <RegisterForm onSubmit={this.handleSubmit} />
      </div>
    );
  }
}

我收到並收到錯誤：

Uncaught Error: You must pass a component to the function returned by connect. Instead received {"kind":"class","elements":[{"kind":"field","key":"handleSubmit","placement":"own","descriptor":{"configurable":true,"writable":true,"enumerable":false}},{"kind":"method","key":"render","placement":"prototype","descriptor":{"writable":true,"configurable":true,"enumerable":false}}]}

我正在使用帶有babel-loader的Webpack 4。 我的.babelrc文件是：

{
  "presets": [
      "@babel/preset-env",
      "@babel/preset-react"
    ],
    "plugins": [
      "@babel/plugin-proposal-class-properties",
      ["@babel/plugin-proposal-decorators", { "decoratorsBeforeExport": true }]
    ]
}

在我看來，connect函數的目標對象是類，但connect函數正在接收該類的屬性描述符。 我知道React和Redux團隊不鼓勵裝飾者。 這是一個相關的SO問題： React-Redux @connect語法錯誤

如何讓@connect裝飾器工作？

Answer 1

確保在插件類屬性之前注入裝飾器插件

{
  "plugins": [
    "@babel/plugin-proposal-decorators",
    "@babel/plugin-proposal-class-properties"
  ]
}

巴別塔-插件，建議，裝飾
