I have a react app running with webpack and I want to make an element draggable using jquery UI. I've added the library with
How can I import jquery ui into the component
Error:
(...).draggable is not a function
$(this.productElm).draggable({
//Install:
yarn add jquery-ui
// Component file:
import $ from "jquery";
import draggable from 'jquery-ui';
export class Item extends React.Component {
componentDidMount(){
this.setPlacement();
document.addEventListener('mousedown', this.handleOutsideClick, false)
this.initInterations()
}
initInterations(){
setTimeout(() => {
$(this.productElm).draggable({
addClasses: false,
stop: (e, ui) => {
if(this.props.onChange){
this.props.onChange({
name: 'move',
x: ui.position.left,
y: ui.position.top
}, this.props.item)
}
}
})
})
}
}
Seems like you can import the various jquery ui 'widgets' like this
import 'jquery-ui/ui/widgets/draggable';
import 'jquery-ui/ui/widgets/resizable';
To work out the path for the import, lookin the node modules folder for what you are importing.

I need such an editor on react https://cloverhearts.github.io/quilljs-markdown/ , as you can see in it you can put markdown characters directly into the text.
when I do this
import React, { Component } from 'react'
import './App.css'
import ReactQuill from 'react-quill'
import Quill from 'quill'
import QuillMarkdown from 'quilljs-markdown'
const App = () => {
const editor = new Quill('#editor', {
theme: 'snow'
})
new QuillMarkdown(editor)
return (
<div className='app'>
{/*<MyComponent/>*/}
<div id="editor"></div>
</div>
)
}
export default App
I get error TypeError: Cannot read property 'on' of undefined
as I understand I need jQuery for work, but I use react, I found https://www.npmjs.com/package/react-quill this quilljs for react, but I don't know how to combine it with markdown https://www.npmjs.com/package/quilljs-markdown
can anyone help?
I found the solution for this after hours of trying this out.
What you have to do is this:
Create a module for ReactQuill
Register the module.
Pass modules to react quill
Shown Below.
Step 01
const modules = {
markdownOptions: {}
};
Step 02
Quill.register('modules/markdownOptions', QuillMarkdown);
Step 03
<ReactQuill
modules={modules}
/>
It seems like you are trying to initialize the Quill instance and the markdown module before the editor is ready.
Use useEffect hook to initialize it after the div has been rendered:
import {useEffect} from 'react';
...
useEffect(() => {
const editor = new Quill('#editor', {
theme: 'snow'
});
new QuillMarkdown(editor);
});
I have created one react component and build it using webpack and deployed on server. I want to integrate this component into Aurelia Project.
I tried using below npm module:
https://www.npmjs.com/package/aurelia-react-loader
In above module mentioned, component name need pass into html file. like in example my-react-component.js is passing into html file.
But my React Component is loading into root in html tag using below code:
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
ReactDOM.render((
<App/>
), document.getElementById('root'));
and after running webpack module, it is creating one JavaScript file that is called index_bundle.js file. Here imported App module is main js component. It is rendering into index.html on root element via ReactDOM.
So I am not sure, How I am going to integrate React component link or url into Aurelia application?
Please let me know if you have any doubts in question. I can do explain in detail.
Thanks in advance.

Yeah, it's really easy to integrate a react component in to an Aurelia app. Check out my project where I do just that here: https://github.com/ashleygrant/aurelia-loves-react
I'm not even using the loader plugin you mentioned.
Here's how to wrap a third-party react component in an Aurelia custom element:
import React from 'react';
import ReactDOM from 'react-dom';
import ReactDatePicker from 'react-datepicker';
import { noView, bindable, inject } from 'aurelia-framework';
#noView(['react-datepicker/react-datepicker.css'])
#inject(Element)
export class DatePicker {
#bindable selectedDate;
#bindable onChange;
constructor(element) {
this.element = element;
}
selectedDateChanged() {
this.render();
}
render() {
ReactDOM.render(
<ReactDatePicker
selected={this.selectedDate}
onChange={date => this.onChange({ date: date })}
/>,
this.element
);
}
// How to use native DOM events to pass the changed date
/*render() {
ReactDOM.render(
<ReactDatePicker
selected={this.selectedDate}
onChange={date => {
let event = new CustomEvent('change', { 'detail': date });
// Dispatch the event.
this.element.dispatchEvent(event);
}
}
/>,
this.element
);
}*/
}
And here's how to do it while using a custom react component that is part of the Aurelia project:
import React from 'react';
import ReactDOM from 'react-dom';
import { noView, bindable, inject } from 'aurelia-framework';
import FormattedDate from '../react-components/formatted-date';
#noView()
#inject(Element)
export class ReactDate {
#bindable date;
#bindable format = 'dddd, MMMM D, YYYY';
constructor(element) {
this.element = element;
}
dateChanged() {
this.render();
}
formatChanged() {
this.render();
}
render() {
ReactDOM.render(
<FormattedDate
date={this.date}
format={this.format}
/>,
this.element
);
}
}
As you can see, it's pretty simple. I like doing it by hand rather than using the loader as I can set up databinding for each property so it works in a more "Aurelia-ey" way.
SnapSVG extension for Adobe Animate.cc 2017 is able to create interactivity and animations for the web. I'm currently trying to use an exported SnapSVG Adobe Animate.cc project in my REACT JS WebApplication.
What I've done so far:
Imported snapsvg-cjs from npm( modified snapsvg to use succesfull in React)
Imported axios to load custom json file generated from SnapSVG extension in Animate.cc
Excluded minified code with eslintignore from SnapSVGAnimator. lib, generated while publishing SVG animation from Animate.cc to work properly without the ESlinting warnings.
Create a componentDidMount function
current code:
import React, {Component} from 'react';
import { Link } from 'react-router-dom';
import axios from 'axios';
import { SVGAnim } from './SnapSVGAnimator.js';
import snapsvg from 'snapsvg-cjs';
componentDidMount(){
axios.get(jsonfile)
.then(response => {
const json = response.request.responseText;
const comp = new SVGAnim(json);
console.log(comp)
});
}
Problem
Following error appears while I log const comp.
Uncaught (in promise) TypeError:
_SnapSVGAnimator.SVGAnim is not a constructor
During the publish render in Animate.cc there are two libs generated; snapsvg.js and SVGAnimator.js
You can import snapsvg-cjs from NPM but SVGAnimator.js isn't available. Importing SVGAnimator.js with the ES6 approach from a curtain directory in your ReactApp isn't possible, not even by excluding it from linting with /* eslint-disable */ 1000 warnings still appears.
Instead of that, add the code to your index.html file, located in the public folder this way
(I've used create-react-app to build this project):
<script type="text/javascript" src="%PUBLIC_URL%/libs/SnapSVGAnimator.min.js"></script>
This is the working code:
import React, { Component } from 'react';
//axios for asnyc usage*/
import axios from 'axios';
//Snapsvg-cjs works out of the box with webpack
import Snapsvg from 'snapsvg-cjs';
//snap.json is located in the public folder, dev-build folder(ugly approach).
let jsonfile = "snap.json";
class SVGAnimator extends Component {
constructor(props){
super(props);
this.state = {
data: ''
}
}
componentDidMount(){
axios.get(jsonfile)
.then(response => {
this.setState({ data: response.data })
});
}
getSVG(){
if(this.state.data){
const container = document.getElementById('container');
const SVG = new window.SVGAnim(this.state.data, 269, 163, 24)
container.appendChild(SVG.s.node);
}
}
render() {
return (
<div id="container">
{ this.getSVG()}
</div>
);
}
}
export default SVGAnimator;
I have included material-ui (and react-tap-event-plugin) in my project and added 3 buttons to one of my components:
<RaisedButton onClick={this.props.onSave} label="Save" style={styles.button}/>
<RaisedButton label='Publish' onClick={this.props.onPublish} style={styles.button}/>
<RaisedButton label='Cancel' onClick={this.onCancel.bind(this)} style={styles.buttonCancel}/>
when I click on any of these, they go very dark grey and when I click again, they go black (and stay like that). The whole applications goes bonkers, the react routing no longer works (I can see the URL changing in the address bar, but the view doesn't refresh). This all looks pretty bad for a button click :)
Any idea what I may be doing wrong? (I take care of the childContext as described in the docs, so the muiTheme is loaded).
I forgot to check the console... there are 3 exceptions whenever I press the button:
1)
vendor.js:12 Uncaught Error: addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's render method, or you have multiple copies of React loaded (details: https://facebook.github.io/react/warnings/refs-must-have-owner.html).(…)
2)
ReactTransitionGroup.js:176 Uncaught TypeError: Cannot read property 'componentWillLeave' of undefined(…)
3)
vendor.js:12 Uncaught Error: removeComponentAsRefFrom(...): Only a ReactOwner can have refs. You might be removing a ref to a component that was not created inside a component's render method, or you have multiple copies of React loaded (details: https://facebook.github.io/react/warnings/refs-must-have-owner.html).(…)
In the component that uses FlatButton (or RaisedButton neither work) I have this:
1) Import:
import FlatButton from 'material-ui/FlatButton'; //eslint-disable-line
import baseTheme from 'material-ui/styles/baseThemes/lightBaseTheme';
import getMuiTheme from 'material-ui/styles/getMuiTheme';
2) in the class
getChildContext() {
return { muiTheme: getMuiTheme(baseTheme) };
}
3) and a static declaration:
EditorComponent.childContextTypes = {
muiTheme: React.PropTypes.object.isRequired,
};
Feels like I'm doing all that's required.
This may be related to what I'm experiencing:
https://github.com/callemall/material-ui/issues/2818
So probably the issue is caused by material-ui distributing it's own version of React? What's the point in that? But... my version of material-ui doesn't have a node_modules folder, so no extra React either...
Source for a component importing and using FlatButton
import React from 'react'; // eslint-disable-line
import Input from '../../../components/common/textInput'; // eslint-disable-line
import BaseEditorComponent from '../base/EditorComponent';
import FlatButton from 'material-ui/FlatButton'; //eslint-disable-line
import baseTheme from 'material-ui/styles/baseThemes/lightBaseTheme';
import getMuiTheme from 'material-ui/styles/getMuiTheme';
export default class EditorComponent extends BaseEditorComponent {
constructor() {
super();
this.state = {
textValue: 'Enter value'
};
}
getChildContext() {
return { muiTheme: getMuiTheme(baseTheme) };
}
_onChange(e) {
this.setState({
textValue: e.target.value
});
}
render() {
return (
<div>
<Input
value={this.state.textValue}
name="SimpleText"
label="Simple Text Value:"
onChange={this._onChange.bind(this)}
/>
<FlatButton label="Test"/>
</div>
);
}
}
EditorComponent.childContextTypes = {
muiTheme: React.PropTypes.object.isRequired,
};
Also, the BaseEditorComponent:
import React from 'react';
import widgetActions from '../../widgets/WidgetActions';
import widgetInstanceStore from '../../widgets/WidgetInstanceStore';
export default class EditorComponent extends React.Component {
constructor() {
super();
}
componentDidMount() {
this.setState(widgetInstanceStore.getWidgetInstanceState(this.props.widgetId) || {});
}
save() {
widgetActions.saveWidgetInstanceState(this.props.widgetId, this.state);
}
}
Have you tried to use onTouchTap instead of onClick?
If #1 doesn't help, please show more code - component with above code and it's parent component.
As per https://github.com/callemall/material-ui/issues/2818 the solution was to include react-addons-transition-group alongside react in the browserify bundle. So it's good to know that it's not only NPM where a 2nd copy of react can slip through, but also browserify or webpack.

I want to use marked in reactjs as described in the reactjs docs.
<div>{marked(mystring)}</div>
I use babel so I import marked like this:
import { marked } from 'marked';
Unfortunately the import statement does not work. marked is not defined.
How do I have to import marked here, so that I can use it?
Here's one way to use marked with React:
Ensure that you've installed marked
Include marked in your project's package.json file:
// package.json
{
dependencies: {
react: "^17.0.0",
marked: "^4.0.0",
},
}
Import marked in your .jsx (or related) file:
import { marked } from "marked";
Use the dangerouslySetInnerHTML approach as shown in the example below:
import React from "react";
import { marked } from "marked";
class MarkdownExample extends React.Component {
getMarkdownText() {
var rawMarkup = marked.parse("This is _Markdown_.");
return { __html: rawMarkup };
}
render() {
return <div dangerouslySetInnerHTML={this.getMarkdownText()} />;
}
}
The dangerouslySetInnerHTML attribute gives you the ability to work with raw (HTML) markup. Make sure to take care when using this attribute, though!
Alternative (Safe)
If you don't want to use dangerouslySetInnerHTML and safely render HTML. Try marked-react, which internally uses marked to render the html elements as react components
npm i marked-react
import Markdown from "marked-react";
const MarkdownComponent = () => {
return <Markdown>{rawmarkdown}</Markdown>;
};
Another alternative is react-markdown
Here is another way of using marked with React Hooks:
Create your MarkedConverter component
import { useState } from 'react'
import marked from 'marked'
export const MarkedConverter = () => {
const [markedVal, setMarkedVal] = useState(
'# Welcome to my React Markdown Previewer!'
)
return <div dangerouslySetInnerHTML={createMarkUp(markedVal)}></div>
}
Create Markup function and pass the value from MarkedConverter Component
export const createMarkUp = (val) => {
return { __html: marked(val) }
}
Finally you can import MarkedConverter Component to any of your Component
With the marked-wrapper react-marked-markdown:
import { MarkdownPreview } from 'react-marked-markdown'
export default ({ post }) => (
<div>
<h1>{ post.title }</h1>
<MarkdownPreview value={ post.content }/>
</div>
)
If you just want to import marked:
import marked from 'marked';
Then call the function in your component:
marked('# Markdown');
Here's an example on how to use marked with react:
Install marked with NPM : npm i marked
import it in your react app (this example is created with create-react-app), and using it
example of a react component using "marked"
result in the browser :
preview
