I would like to create component API for dialog window, based on https://github.com/reactjs/react-modal
I want render react component with renderDOM, get component instance and call API of modal, it does mean for example open(), close() etc.
So, more precisely I would like to work with current state of component, (like API works) not with props.
I have simple base class for all modals:
export class BaseModal extends Modal {
constructor() {
super();
this.state = BaseModal._getInitState();
}
static get style() {
return {
content: {
top: '50%',
left: '50%',
right: 'auto',
bottom: 'auto',
marginRight: '-50%',
transform: 'translate(-50%, -50%)'
}
};
}
open() {
this.setState({isOpen: true});
}
close() {
this.setState({isOpen: false});
}
render() {
return this.state.isOpen ? (
<div className="modal modal__{this.name}">
<Modal isOpen={this.state.isOpen}
onRequestClose={this.close}
style={BaseModal.style}
contentLabel={this.getHeaderContent()}
parentSelector={BaseModal._getParentSelector}>
<button onClick={this.close}>X</button>
<div className="modal__body">
{this.getBodyContent()}
</div>
<div className="modal__footer">
{this.getFooterContent()}
</div>
</Modal>
</div>
) : null;
}
getHeaderContent() {
throw new Error("Not implement in child class.");
}
getBodyContent() {
throw new Error("Not implement in child class.");
}
getFooterContent() {
throw new Error("Not implement in child class.");
}
static _getInitState() {
let state = {};
state.isOpen = false;
}
}
Now I have child component:
export class RecommendTripModal extends BaseModal {
getHeaderContent() {
return "Test modal dialog";
}
getBodyContent() {
return <p>Test modal body</p>;
}
getFooterContent() {
return <p>Test modal footer</p>;
}
}
Ok, this is fine, but now I want to call something like this:
let recommendedTripModal = ReactDOM.render(React.createElement(RecommendTripModal, null), document.querySelector("#modals"));
//open dialog
recommendedTripModal.open();
But now is problem with context. Because this.state.isOpen has RecommendTripModal context and state is null. Is there way, how to solved this problem with react? And is this solid way? Or I should create required API different way?
Thank you for your time!
Okay, let's dig a little bit deeper here, best way is to use React context and HoC magic power
Modal.js
import React from "react";
import PropTypes from "prop-types";
import { omit } from "lodash";
export class Modal extends React.Component {
static contextTypes = {
modalOpen: PropTypes.bool
};
static propTypes = {
children: PropTypes.node
};
render() {
if (!this.context.modalOpen) return null;
return (
<div>
<h1>I am base modal title</h1>
<div>{this.props.children}</div>
</div>
);
}
}
export class ModalContext extends React.Component {
static childContextTypes = {
modalOpen: PropTypes.bool
};
static defaultProps = {
onOpen: () => {},
onClose: () => {}
};
static propTypes = {
children: PropTypes.func.isRequired
};
constructor(...args) {
super(...args);
this.handleOpen = this.handleOpen.bind(this);
this.handleClose = this.handleClose.bind(this);
}
state = {
isOpen: false
};
getChildContext() {
return {
modalOpen: this.state.isOpen
};
}
handleClose() {
if (this.state.isOpen) {
this.setState({ isOpen: false });
}
}
handleOpen() {
if (!this.state.isOpen) {
this.setState({ isOpen: true });
}
}
render() {
const { identity, children } = this.props;
return children({
[identity]: {
open: this.handleOpen,
close: this.handleClose,
isOpen: this.state.isOpen
}
});
}
}
export default function modal(initialModalProps = {}) {
return function(Component) {
const componentName =
Component.displayName || Component.name || "Component";
return class extends React.Component {
static displayName = `Modal(${componentName})`;
static propTypes = {
identity: PropTypes.string
};
static defaultProps = {
identity: "modal"
};
render() {
const { identity } = this.props;
return (
<ModalContext
identity={identity}
{...initialModalProps}
{...this.props[identity]}
>
{modalProps => (
<Component
{...omit(this.props, identity, "identity")}
{...modalProps}
/>
)}
</ModalContext>
);
}
};
};
}
HelloWorldModal.js
import React from "react";
import withModal, { Modal } from "./modal";
class HelloWorldModal extends React.Component {
render() {
const { modal } = this.props;
return (
<div>
<button type="button" onClick={modal.open}>
Open Modal
</button>
<button type="button" onClick={modal.close}>
Close Modal
</button>
<Modal>Yeah! I am sample modal!</Modal>
</div>
);
}
}
export default withModal()(HelloWorldModal);
In case you are lazy, I prepared a codesandbox with working code :)

Edit: I have included the full code for better clarity
I am not sure if this is possible. I am trying to pass an onClick event via props but the click event does not work.
The parent component looks like this:
import React from 'react'
import { getProductsById } from '../api/get'
import Product from './Product'
import { instanceOf } from 'prop-types'
import { withCookies, Cookies } from 'react-cookie'
class Cart extends React.Component {
static propTypes = {
cookies: instanceOf(Cookies).isRequired
}
constructor(props) {
super(props)
const { cookies } = props;
this.state = {
prods: cookies.get('uircartprods') || '',
collapsed: true,
total: 0,
}
this.expand = this.expand.bind(this)
this.p = [];
}
componentDidMount() {
this.getCartProducts()
}
handleClick = (o) => {
this.p.push(o.id)
const { cookies } = this.props
cookies.set('uircartprods', this.p.toString(), { path: '/' , sameSite: true})
this.setState({prods: this.p })
console.log('click')
}
getCartProducts = async () => {
let products = []
if (this.state.prods !== '') {
const ts = this.state.prods.split(',')
for (var x = 0; x < ts.length; x++) {
var p = await getProductsById(ts[x])
var importedProducts = JSON.parse(p)
importedProducts.map(product => {
const prod = <Product key={product.id} product={product} handler={() => this.handleClick(product)} />
products.push(prod)
})
}
this.setState({products: products})
}
}
expand(event) {
this.setState({collapsed: !this.state.collapsed})
}
handleCheckout() {
console.log('checkout clicked')
}
render() {
return (
<div className={this.state.collapsed ? 'collapsed' : ''}>
<h6>Your cart</h6>
<p className={this.state.prods.length ? 'hidden' : ''}>Your cart is empty</p>
{this.state.products}
<h6>Total: {this.props.total}</h6>
<button onClick={this.handleCheckout} className={this.state.prods.length ? '' : 'hidden' }>Checkout</button>
<img src="./images/paypal.png" className="paypal" alt="Paypal" />
<a className="minify" onClick={this.expand} alt="My cart"></a>
<span className={this.state.prods.length ? 'pulse' : 'hidden'}>{this.state.prods.length}</span>
</div>
)
}
}
export default withCookies(Cart)
The Product component:
import React from 'react';
class Product extends React.Component {
constructor(props) {
super(props);
this.state = {
showDetails: false,
showModal: false,
cart: []
}
this.imgPath = './images/catalog/'
}
render() {
return (
<div className="Product">
<section>
<img src={this.imgPath + this.props.product.image} />
</section>
<section>
<div>
<h2>{this.props.product.title}</h2>
<h3>{this.props.product.artist}</h3>
<p>Product: {this.props.product.product_type}</p>
<h4>${this.props.product.price}</h4>
<button className="button"
id={this.props.product.id} onClick={this.props.handler}>Add to cart</button>
</div>
</section>
</div>
)
}
}
export default Product
If I log this.props.handler I get undefined. Everything works apart from the click handler, I was wondering if it might have something to with the async function. I am very new to React, there are still some concepts I'm not sure about, so any help is appreciated.
Okay, I see a few issues here.
First, there is no need to call this.handleClick = this.handleClick.bind(this) in the constructor, because you are using an arrow function. Arrow functions do not have a this context, and instead, accessing this inside your function will use the parent this found in the Class.
Secondly, it is wrong to store components in state. Instead, map your importedProducts inside the render function.
Thirdly, the issue with your handler is that this.props.handler doesn't actually call handleClick. You will notice in the definition handler={(product) => this.handleClick} it is returning the function to the caller, but not actually calling the function.
Try this instead.
class Product extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<button className="button" id={this.props.product.id} onClick={this.props.handler}>
Add to cart
</button>
</div>
);
}
}
export default Product;
import Product from './Product'
class Cart extends React.Component {
constructor(props) {
super(props);
}
handleClick = (o) => {
console.log('click');
};
render() {
return (
<div>
{importedProducts.map((product) => {
return <Product key={product.id} product={product} handler={() => this.handleClick(product)} />;
})}
</div>
);
}
}
export default Cart;
I want to slide out a React component when it umounts. I am using CSSTransition for the animation which works great for mounting, but not unmounting. Somehow I need to delay the unmount process. All the off-the-shelf solutions sadly do not work for me. I am removing an element by doing a post request and then actually removing it in the UI with a SignalR callback.
To make my sequence more clear, I created a sequence diagram:
This is my code right now:

That is using jQuery in another project of mine. That is what I want to achive in React.
You can delay unmounting the component. Write a hoc and use a setTimeout. Maintain a state say shouldRender.
hoc
function delayUnmounting(Component) {
return class extends React.Component {
state = {
shouldRender: this.props.isMounted
};
componentDidUpdate(prevProps) {
if (prevProps.isMounted && !this.props.isMounted) {
setTimeout(
() => this.setState({ shouldRender: false }),
this.props.delayTime
);
} else if (!prevProps.isMounted && this.props.isMounted) {
this.setState({ shouldRender: true });
}
}
render() {
return this.state.shouldRender ? <Component {...this.props} /> : null;
}
};
}
usage
function Box(props) {
return (
<BoxWrapper isMounted={props.isMounted} delay={props.delay}>
✨🎶✨🎶✨🎶✨🎶✨
</BoxWrapper>
);
}
const DelayedComponent = delayUnmounting(Box);

How to write the unit test case for the given container which is associated with the component given as below?
Here the PopupNotification.jsx is a component file which has PopupNotification.js as a container file.
I want a jest unit test case implementation for the container file.
PopupNotification.jsx --> component file
import React from "react";
import PropTypes from "prop-types";
import { notyIcons, notyTimeout } from "../helpers/constants";
class PopupNotification extends React.Component {
constructor(props) {
super(props);
this.state = {
showNoty: props.showNoty
};
this.notyTimer = null;
}
static getDerivedStateFromProps(nextProps, prevState) {
return {
showNoty: nextProps.showNoty
};
}
shouldComponentUpdate() {
return true;
}
startNotyTimer() {
let __self = this;
if (this.notyTimer) {
clearTimeout(this.notyTimer);
}
this.notyTimer = setTimeout(function() {
__self.closeNoty();
}, notyTimeout);
}
componentWillUnmount() {
if (this.notyTimer) {
clearTimeout(this.notyTimer);
}
this.setState({ showNoty: false });
}
closeNoty() {
let { id } = this.props;
this.props.clearNotification(id);
this.setState({
showNoty: false
});
}
getNotyIcon() {
return <i className={`notification-popup__icon pos-l-m ${notyIcons[this.props.type]}`} />;
}
getNotyLayout() {
let notyIcon = this.getNotyIcon();
let { message: notyMessage, type } = this.props;
return (
<div className={`pure-g notification-popup ${type}`}>
<div className="pure-u-1-8 pos">{notyIcon}</div>
<div className="pure-u-7-8">
<div className="u-margin-8--left">{notyMessage}</div>
</div>
</div>
);
}
render() {
var notyLayout = null;
if (this.state.showNoty) {
this.startNotyTimer();
notyLayout = this.getNotyLayout();
}
return notyLayout;
}
}
PopupNotification.propTypes = {
message: PropTypes.string,
type: PropTypes.string,
id: PropTypes.number,
showNoty: PropTypes.bool,
clearNotification: PropTypes.func
};
PopupNotification.defaultProps = {
message: "",

};
export default PopupNotification;
PopupNotification.js --> container File
import { connect } from "react-redux";

I suggest using redux-mock-store to gain full control over your store. Then you can do things like
const actions = store.getActions()
expect(actions).toEqual([expectedPayload])
Copied from their docs
Since this is a unit test, you just need to test what this container is responsible for, and from what I see from your example that it is exposing the redux connected component, so you should test that your mapStateToProps & mapDispatchToProps are executing correctly.
This is my Accordion component
import React, {Component, Fragment} from 'react';
import ArrowTemplate from "./ArrowTemplate";
import ContentTemplate from "./ContentTemplate";
class Accordion extends Component {
constructor(props) {
super(props);
this.state = {isAccordionExpanded: false};
this.foldAccordion = this.foldAccordion.bind(this);
this.expandAccordion = this.expandAccordion.bind(this);
}
expandAccordion() {
console.log(1);
this.setState({isAccordionExpanded: true});
}
foldAccordion() {
console.log(2);
this.setState({isAccordionExpanded: false});
}
render() {
const {state} = this;
const {isAccordionExpanded} = state;
if (isAccordionExpanded === false) {
return (
<Fragment>
<ArrowTemplate
aria={`aria-expanded="true"`}
onClick={this.expandAccordion}
direction={'down'}
color={'black'}
styles={'background:yellow'}
/>
</Fragment>
);
} else if (isAccordionExpanded === true) {
return (
<Fragment>
<ArrowTemplate
aria={`aria-expanded="true"`}
onClick={this.foldAccordion}
color={'black'}
direction={'up'}
/>
<ContentTemplate/>
</Fragment>
);
}
}
}
export default Accordion;
this is the ArrowTemplate
import React from "react";
import BlackDownArrowSVG from './svgs/black-down-arrow.svg';
import WhiteDownArrowSVG from './svgs/white-down-arrow.svg';
import styled from 'styled-components';
import PropTypes from 'prop-types';
ArrowTemplate.propTypes = {
color: PropTypes.string.isRequired,
direction: PropTypes.string.isRequired,
styles: PropTypes.string,
aria: PropTypes.string.isRequired,
};
function ArrowTemplate(props) {
const {color, direction, styles, aria} = props;
const StyledArrowTemplate = styled.img.attrs({
src: color.toLowerCase() === "black" ? BlackDownArrowSVG : WhiteDownArrowSVG,
aria,
})`
${direction.toLowerCase() === "up" ? "translate: rotate(180deg)" : ""}
${styles}
`;
return <StyledArrowTemplate/>;
}
export default ArrowTemplate;
And here are my related tests
describe("<Accordion/>",
() => {
let wrapper;
beforeEach(
() => {
wrapper = shallow(
<Accordion/>
);
}
);
it('should have one arrow at start',
function () {
expect(wrapper.find(ArrowTemplate)).toHaveLength(1);
}
);
it('should change state onClick',
function () {
wrapper.find(ArrowTemplate).simulate("click");
expect(wrapper.state().isAccordionExpanded).toEqual(true);
}
);
it('should call FoldAccordionMock onClick',
function () {
wrapper.setState({isAccordionExpanded: true});
wrapper.find(ArrowTemplate).simulate("click");
expect(wrapper.state().isAccordionExpanded).toEqual(false);
}
);
it('should display content if isAccordionExpanded = true',
function () {
wrapper.setState({isAccordionExpanded: true});
expect(wrapper.find(ContentTemplate).exists()).toEqual(true);
}
);
it('should hide content if isAccordionExpanded = false',
function () {
expect(wrapper.find(ContentTemplate).exists()).toEqual(false);
}
);
}
);
So the problem is that when I tun the tests .simulate(click) seems to work, and all tests pass. But when I click the component myself, nothing happens. Not even a console log. Changing the onClick to onClick={()=>console.log(1)} doesn't work either. Any ideas what's wrong?
StyledArrowTemplate inner component does not know anything about onClick.
ArrowTemplate doesn't know what onClick means, it's just another arbitrary prop to it.
But, if you do as #ravibagul91 said in their comment, you should pass down onClick again, StyledArrowTemplate might know what onClick means.
So just add <StyledArrowTemplate onClick={props.onClick}/>
Accordion Component
import React, { Component, Fragment } from "react";
import ArrowTemplate from "./ArrowTemplate";
import ContentTemplate from "./ContentTemplate";
class Accordion extends Component {
constructor(props) {
super(props);
this.state = { isAccordionExpanded: false };
}
toggleAccordian = () => {
console.log(1);
this.setState({ isAccordionExpanded: !isAccordionExpanded });
};
render() {
const { state } = this;
const { isAccordionExpanded } = state;
if (isAccordionExpanded) {
return (
<Fragment>
<ArrowTemplate
aria={`aria-expanded="true"`}
onClick={() => this.toggleAccordian()}
color={"black"}
direction={isAccordionExpanded ? "up" : "down"}
styles={`background:{isAccordionExpanded ? 'yellow' : ''}`}
/>
<ContentTemplate />
</Fragment>
);
}
}
}
export default Accordion;
In my app, I'm trying to use Popper to create a tooltip over every element in the app.
(Usually, I would only show a single tooltip, but for a presentation I want to show more than one).
I wrote this utility Component to attach tooltip directly to ref.
It works pretty well, but when I try to use it inside an [].map() like regular react components, I lose all my positioning:
https://bit.dev/bit/base/atoms/ref-tooltip?example=5e81d946443f4900195606b7
import React, { Component } from 'react';
import { RefTooltip } from '#bit/bit.base.atoms.ref-tooltip'
export default class ExampleUsage extends Component {
state = { ref: [] };
handleRef = (elem) => {
if (this.state.ref.some(x => x === elem)) return;
this.setState({ ref: [elem] });
}
render() {
return (
<div>
<span ref={this.handleRef}>target</span>
{ /*
* (!)
* This .map() breaks tooltip
*
*/ }
{this.state.ref.map((elem, idx) => (
<RefTooltip key={idx} targetElement={elem}>
"tooltip"
</RefTooltip>
))}
</div>
);
}
}
