将 Quill 导入 React 应用程序抛出“React 未定义"、“意外的令牌导入" [英] Importing Quill to React app throws "React is not defined", "Unexpected token import"

问题描述

我正在尝试让 Quill 在我的 React 应用程序上工作，但根据我的 webpack 配置，它会引发两个错误:

<块引用>

未捕获的语法错误:意外的令牌导入

或

<块引用>

未捕获的引用错误:未定义 React

请注意，我没有使用 react-quill 或 create-react-app.

解决第一个错误会产生另一个错误，我已经读到我需要在 webpack 中创建一个例外以允许它从 quill 文件夹中导入.

排除:/node_modules/

进入

/node_modules(?!\/quill)/

现在它抛出第二个错误.

我的 webpack 配置文件:

module.exports = {入口: ['./src/index.js'],输出: {路径:__目录名，公共路径:'/'，文件名:'bundle.js'},模块: {装载机:[{排除:/node_modules(?!\/quill)/,装载机:'通天塔'，询问: {预设:['react', 'es2015', 'stage-1']}}]},解决: {扩展名:['', '.js', '.jsx']},开发服务器:{historyApiFallback: 真,内容库:'./'}};

我正在使用 Quill 文档中的基本代码来导入所需的内容:

import React, { Component } from 'react';从'羽毛笔/核心'导入羽毛笔；从 'quill/modules/toolbar' 导入工具栏；从 'quill/themes/snow' 导入雪；从 'quill/formats/bold' 导入粗体；从 'quill/formats/italic' 导入斜体；从 'quill/formats/header' 导入标题；Quill.register({'模块/工具栏':工具栏，'主题/雪':雪，'格式/粗体':粗体，'格式/斜体':斜体，'格式/标题':标题});类教程扩展组件{构造函数(道具){超级(道具)；this.editor = null;}使成为(){返回 (<div className="动词容器"><div className="editor"></div>

);}}导出默认教程；

当我只导入时:

从'quill'导入Quill；

或

从'quill/core'导入Quill；

如果我像这样初始化它，就会出现一个基本的编辑器:

<块引用>

this.editor = new Quill('.editor');

但是当我尝试导入时

从'quill/themes/snow'导入雪；

显示:

<块引用>

React 未定义

如果我遗漏了任何重要信息，请告诉我.

解决方案

你的问题帮助我弄清楚如何让 Quill 在 React 应用程序中工作，所以谢谢你！

React 未定义"错误可能与 Quill 无关.

此处可能的解决方案:未捕获的 ReferenceError:React 未定义>

就其价值而言，以下是我将 Quill 导入 React 组件的方式.

注意这是在 React 应用程序中使用 Quill，而不是使用 react-quill npm 包.

从'react'导入React；//导入 'quill/dist/quill.core.css';导入 'quill/dist/quill.snow.css';从'羽毛笔/核心'导入羽毛笔；从 'quill/modules/toolbar' 导入工具栏；从 'quill/themes/snow' 导入雪；//snow 有效，但需要导入和注册格式，并替换图标...从 'quill/formats/bold' 导入粗体；从 'quill/formats/italic' 导入斜体；从 'quill/formats/header' 导入标题；从 'quill/formats/underline' 导入下划线；从 'quill/formats/link' 导入链接；import List, { ListItem } from 'quill/formats/list';从 'quill/ui/icons' 导入图标；导出默认类 QuillEditor 扩展 React.Component {componentDidMount() {Quill.register({'模块/工具栏':工具栏，'主题/雪':雪，'格式/粗体':粗体，'格式/斜体':斜体，'格式/标题':标题，'格式/下划线':下划线，格式/链接":链接，'格式/列表':列表，'格式/列表/项目':列表项目，'ui/icons': 图标});var icons = Quill.import('ui/icons');图标['bold'] = '<i class="fa fa-bold" aria-hidden="true"></i>';图标['斜体'] = '<i class="fa fa-italic" aria-hidden="true"></i>';图标['underline'] = '<i class="fa fa-underline" aria-hidden="true"></i>';图标['link'] = '<i class="fa fa-link" aria-hidden="true"></i>';图标['clean'] = '<i class="fa fa-eraser" aria-hidden="true"></i>';var quill = new Quill('#editor', {theme: 'snow',//this 需要跟在上面，注册 Snow...占位符:写一些很棒的东西......"});}//componentDidMount使成为() {返回 (<div><div id="QuillEditor-container">{/* */}<div id="编辑器"><p>你好世界！</p><p>一些初始的<strong>粗体</strong>文本
<p></p>

)}}

I'm trying to get Quill to work on my React app but depending on my webpack config it throws two errors:

Uncaught SyntaxError: Unexpected token import

or

Uncaught ReferenceError: React is not defined

Please note that I'm not using react-quill nor create-react-app.

Solving the first error produces another, I've read that I need to make an exception in webpack to allow it to import from quill folder.

exclude: /node_modules/

into

/node_modules(?!\/quill)/

Now it throws the second error.

My webpack config file:

module.exports = {
  entry: [
    './src/index.js'
  ],
  output: {
    path: __dirname,
    publicPath: '/',
    filename: 'bundle.js'
  },
  module: {   
    loaders: [{
      exclude: /node_modules(?!\/quill)/,
      loader: 'babel',
      query: {
        presets: ['react', 'es2015', 'stage-1']
      }
    }]
  },
  resolve: {
    extensions: ['', '.js', '.jsx']
  },
  devServer: {
    historyApiFallback: true,
    contentBase: './'
  }
};

I'm using basic code from Quill docs to import what's needed:

import React, { Component } from 'react';

import Quill from 'quill/core';

import Toolbar from 'quill/modules/toolbar';
import Snow from 'quill/themes/snow';

import Bold from 'quill/formats/bold';
import Italic from 'quill/formats/italic';
import Header from 'quill/formats/header';

Quill.register({
  'modules/toolbar': Toolbar,
  'themes/snow': Snow,
  'formats/bold': Bold,
  'formats/italic': Italic,
  'formats/header': Header
});
class Tutorial extends Component {
    constructor(props){
        super(props);
        this.editor = null;
    }
    render(){
        return (
            <div className="verb-container">
                <div className="editor"></div>
            </div>
        );
    }
}

export default Tutorial;

When I import just:

import Quill from 'quill';

or

import Quill from 'quill/core';

A basic editor appears if I initialize it like this:

this.editor = new Quill('.editor');

But when I try to import

import Snow from 'quill/themes/snow';

It shows:

React is not defined

If I missed any important information, please let me know.

解决方案

Your question helped me figure out how to get Quill working in a React app, so thank you for that!

The "React is not defined" error may have nothing to do with Quill.

Possible solution here: Uncaught ReferenceError: React is not defined

For what it's worth, here is how I imported Quill into a React component.

Note this is using Quill in a React app, and not using the react-quill npm package.

import React from 'react';

// import 'quill/dist/quill.core.css';
import 'quill/dist/quill.snow.css';

import Quill from 'quill/core';
import Toolbar from 'quill/modules/toolbar';
import Snow from 'quill/themes/snow'; //snow works, but need to import and register formats, and replace icons...

import Bold from 'quill/formats/bold';
import Italic from 'quill/formats/italic';
import Header from 'quill/formats/header';
import Underline from 'quill/formats/underline';
import Link from 'quill/formats/link';
import List, { ListItem } from 'quill/formats/list';

import Icons from 'quill/ui/icons'; 

export default class QuillEditor extends React.Component {

  componentDidMount() {

    Quill.register({
      'modules/toolbar': Toolbar,
      'themes/snow': Snow,
      'formats/bold': Bold,
      'formats/italic': Italic,
      'formats/header': Header,
      'formats/underline': Underline,
      'formats/link': Link,
      'formats/list': List,
      'formats/list/item': ListItem,
      'ui/icons': Icons
    });

    var icons = Quill.import('ui/icons');
    icons['bold'] = '<i class="fa fa-bold" aria-hidden="true"></i>';
    icons['italic'] = '<i class="fa fa-italic" aria-hidden="true"></i>';
    icons['underline'] = '<i class="fa fa-underline" aria-hidden="true"></i>';
    icons['link'] = '<i class="fa fa-link" aria-hidden="true"></i>';
    icons['clean'] = '<i class="fa fa-eraser" aria-hidden="true"></i>'; 

    var quill = new Quill('#editor', {
      theme: 'snow', //this needs to come after the above, which registers Snow...
      placeholder: "Write something awesome..."
    });
  } //componentDidMount

  render() {
    return (
      <div>
          <div id="QuillEditor-container">
            {/* <!-- Create the editor container --> */}
            <div id="editor">
              <p>Hello World!</p>
              <p>Some initial <strong>bold</strong> text</p>
              <p></p>
            </div>
          </div>
      </div>
    )
  }
}
