从自定义 React 组件库导入和使用组件会导致 Invariant Violation: Invalid hook call

Question

我的工作是制作一个 React UI 工具包/组件库，供我们的产品内部使用。 在 Storybook 上开发和展示时一切正常。

在从 create-react-app 开箱即用的通用项目中测试库时，导入和实现不使用 React Hooks 制作的组件是可以的，但是一旦我们使用使用 Hooks 制作的组件 - Invalid Hook Call 错误显示： https://reactjs.org/warnings/invalid-hook-call-warning.html

已经尝试了那里列出的所有内容（并阅读并尝试了页面上链接的 github 线程解决方案），并且该组件只使用useRef()而没有其他任何东西，所以我们知道没有违反任何规则，React 和 React-dom 版本是最新的，并在项目中运行npm ls react和npm ls react-dom导致react@16.10.2和react-dom@16.10.2没有别的......所以看起来我们没有多个 React？

任何帮助将非常感激！！

UI 套件的webpack.config.js

const path = require('path');

module.exports = {
    mode: 'production',
    entry: './src/index.js',
    output: {
        path: path.resolve('dist'),
        filename: 'index.js',
        libraryTarget: 'commonjs2',
    },
    module: {
        rules: [
            {
                test: /\.jsx?$/,
                exclude: /(node_modules)/,
                use: 'babel-loader',
            },
            {
                test: /\.(eot|svg|ttf|woff|woff2|otf)$/,
                use: [
                    {
                        loader: 'file-loader',
                        options: {
                            name: '[name].[ext]',
                            limit: 10000,
                            mimetype: 'application/font-woff',
                        },
                    },
                ],
            },
        ],
    },
    resolve: {
        alias: {
            components: path.resolve(__dirname, 'src/components/'),
            utils: path.resolve(__dirname, 'src/utils/'),
            themes: path.resolve(__dirname, 'src/themes/'),
        },
        extensions: ['.js', '.jsx'],
    },
    devtool: false,
};

在项目中如何导入和实现组件：

import React from "react";
import logo from "./logo.svg";
import "./App.css";
import { FieldLabel, Button } from "react-ui-kit";

function App() {
  return (
    <div className="App">
      <FieldLabel>THIS IS THE ONE USING the useRef Hook</FieldLabel>
      <Button>This component is totally fine without FieldLabel, this isn't using Hooks</Button>
    </div>
  );
}

export default App;

Answer 1

查看 webpack 配置，我可以看到，UI 套件与包含的react捆绑在一起，这可能会导致问题。

为避免这种情况，您可以使用 webpack 外部设备。

https://webpack.js.org/configuration/externals/

externals 配置选项提供了一种从 output 包中排除依赖项的方法。 相反，创建的包依赖于存在于消费者环境中的依赖项。 此功能通常对库开发人员最有用，但它有多种应用程序。

因此，您可以更新 UI Kit webpack 配置以不包括react ，并且 peerDependencies 应该负责处理库的任何使用者的依赖关系。

更新了 webpack.config

const path = require("path");
module.exports = {
  mode: "production",
  entry: "./src/index.js",
  output: {
    path: path.resolve("dist"),
    filename: "index.js",
    libraryTarget: "commonjs2"
  },
  module: {
    rules: [
      {
        test: /\.jsx?$/,
        exclude: /(node_modules)/,
        use: "babel-loader"
      },
      {
        test: /\.(eot|svg|ttf|woff|woff2|otf)$/,
        use: [
          {
            loader: "file-loader",
            options: {
              name: "[name].[ext]",
              limit: 10000,
              mimetype: "application/font-woff"
            }
          }
        ]
      }
    ]
  },
  resolve: {
    alias: {
      components: path.resolve(__dirname, "src/components/"),
      utils: path.resolve(__dirname, "src/utils/"),
      themes: path.resolve(__dirname, "src/themes/")
    },
    extensions: [".js", ".jsx"]
  },
  externals: {
        // Use external version of React
        react: "react"
 },
  devtool: false
};

我已经发布了一个测试 package 来确认这一点（ react-ui-kit-dontuse ）。
