How to add an aria attribute to a styled component? - styled-components

I am using the styled-components npm package and need to add the aria-haspopup attribute to my extended Button component. I have tried the following, but this doesn't add the attribute:
import Button from './button';
const StyledBtn = Button.attrs({
'aria-haspopup': 'true',
}).extend``;

I found that the solution was:
New styled-components v4 syntax:
import Button from './button';
const StyledBtn = styled(Button).attrs({
'aria-haspopup': 'true',
})``;
Old syntax:
import Button from './button';
const StyledBtn = Button.extend.attrs({
'aria-haspopup': 'true',
})``;
https://www.styled-components.com/docs/api
https://medium.com/styled-components/styled-components-v4-new-final-finalest-for-real-final-final-psd-fa4d83398a77

The solution is:
import Button from './button';
const StyledBtn = Button.attrs(({ value }) => ({
ariaHaspopup: value,
}));

import patch from "virtual-dom/patch";
import createElement from "virtual-dom/create-element";
const betaRender = hv("span", { innerHTML: svgString });

Disable paste image screenshot in jodit-react

I take a screenshot and paste to editor. This make storage is very big. How to disable paste image from clipboard to editor in jodit-react? I'm using jodit-react version 1.0.66.
import React, {useState, useRef} from 'react';
import JoditEditor from "jodit-react";
const Example = ({}) => {
const editor = useRef(null)
const [content, setContent] = useState('')
const config = {
readonly: false // all options from https://xdsoft.net/jodit/doc/
}
return (
<JoditEditor
ref={editor}
value={content}
config={config}
tabIndex={1} // tabIndex of textarea
onBlur={newContent => setContent(newContent)} // preferred to use only this option to update the content for performance reasons
onChange={newContent => {}}
/>
);
}
use the following option
uploader: {
url: 'none'
},

Access theme variables outside withStyles function (react-native-ui-kitten)

I want to use theme variables to style my Icon accordingly. However i cant use style property to fill the Icon element of react-native-ui-kitten but instead have to use the fill property. How can I access theme variables outside of the withStyles function of react-native-ui-kitten
#xk2tm5ah5c
You can use theme property if you wrap your component into withStyles.
Here is an example code:
import React from 'react';
import { View } from 'react-native';
import { Button, Icon, withStyles } from 'react-native-ui-kitten';
const ScreenComponent = (props) => {
const iconColor = props.theme['color-primary-default'];
const FacebookIcon = (style) => (
<Icon {...style} fill={iconColor} name='facebook' />
);
return (
<View>
<Button icon={FacebookIcon}>LOGIN WITH FACEBOOK</Button>
</View>
);
};
export const Screen = withStyles(ScreenComponent);
I'm not quite sure I understand your question completely. Usually when you have a question, you should post some of your code for context.
Here is my answer assuming 'Theme variable' is a hash... Try string interpolation:
fill={`${theme.HEX_COLOR}`}

How to inject Material-UI stylesheets into a jest/react-testing-library test?

It seems that if you don't inject Material-UI stylesheets into a jest/react-testing-library test then jsdom will fail to get the correct styles from your components (e.g. running getComputedStyle(component) will return the incorrect styles for the component).
How you properly setup a jest/react-testing-library test so that the styles are correctly injected into the test? I've already wrapped the components in a theme provider, which works fine.
As a workaround reinserting the whole head (or the element where JSS styles are injected) before assertion seems to apply styles correctly with both getComputedStyle() and react testing library's toHaveStyle():
import React from "react";
import "#testing-library/jest-dom/extend-expect";
import { render } from "#testing-library/react";
test("test my styles", () => {
const { getByTestId } = render(
<div data-testid="wrapper">
<MyButtonStyledWithJSS/>
</div>
);
const button = getByTestId("wrapper").firstChild;
document.head.innerHTML = document.head.innerHTML;
expect(button).toHaveStyle(`border-radius: 4px;`);
});
This will still fail though when you're using dynamic styles, like:
myButton: {
padding: props => props.spacing,
...
}
That's because JSS uses CSSStyleSheet.insertRule method to inject these styles, and it won't appear as a style node in the head. One solution to this issue is to hook into the browser's insertRule method and add incoming rules to the head as style tags. To extract all this into a function:
function mockStyleInjection() {
const defaultInsertRule = window.CSSStyleSheet.prototype.insertRule;
window.CSSStyleSheet.prototype.insertRule = function (rule, index) {
const styleElement = document.createElement("style");
const textNode = document.createTextNode(rule);
styleElement.appendChild(textNode);
document.head.appendChild(styleElement);
return defaultInsertRule.bind(this)(rule, index);
};
// cleanup function, which reinserts the head and cleans up method overwrite
return function applyJSSRules() {
window.CSSStyleSheet.prototype.insertRule = defaultInsertRule;
document.head.innerHTML = document.head.innerHTML;
};
}
Example usage of this function in our previous test:
import React from "react";
import "#testing-library/jest-dom/extend-expect";
import { render } from "#testing-library/react";
test("test my styles", () => {
const applyJSSRules = mockStyleInjection();
const { getByTestId } = render(
<div data-testid="wrapper">
<MyButtonStyledWithJSS spacing="8px"/>
</div>
);
const button = getByTestId("wrapper").firstChild;
applyJSSRules();
expect(button).toHaveStyle("border-radius: 4px;");
expect(button).toHaveStyle("padding: 8px;");
});
This ultimately seems like an issue with JSS and various browser implementations like jsdom and and Blink (at least in Chrome). You can see it in Chrome when trying to modify/enable/disable these style rules (you can't).
The behavior appears to be a result of the JSS library using the CSSOM insertRule API. There's a stylesheet generated in the DOM for the styles we expect in our component, but the tag is empty - it's just used to link the shadow CSS back to the DOM. The styles are never written to the inline stylesheet in the DOM, and as a result, the getComputedStyle method does not return the expected results.
There's an open issue to address this behavior and make development easier.
I switched my custom components to styled-components, which does not have some of these idiosyncrasies.
Material-UI is planning on transitioning soon as well.
You could add this to a custom render function. After rendering, the function pulls the styles out of cssom and puts them into a style tag. Here is an implementation:
let customRender = (ui, options) => {
let renderResult = render(ui, options);
let styleElement = document.createElement("style");
let styleText = "";
for (let styleSheet of document.styleSheets) {
for (let rule of styleSheet.cssRules) {
styleText += rule.cssText + "\n";
}
}
styleElement.textContent = styleText.slice(0, -1);
document.head.appendChild(styleElement);
// remove old style elements
let emptyStyleElements = document.head.querySelectorAll('style[data-jss=""]');
for (let element of emptyStyleElements) {
element.remove();
}
return renderResult;
}
I can't speak specifically to Material-UI stylesheets, but you can inject a stylesheet into rendered component:
import {render} from '#testing-library/react';
import fs from 'fs';
import path from 'path';
const stylesheetFile = fs.reactFileSync(path.resolve(__dirname, '../path-to-stylesheet'), 'utf-8');
const styleTag = document.createElement('style');
styleTag.type = 'text/css';
styleTag.innerHTML = stylesheetFile;
const rendered = render(<MyComponent>);
rendered.append(style);
You don't necessarily have to read from a file, you can use whatever text you want.

How to mount styles inside shadow root using cssinjs/jss

I'm trying to use https://material-ui.com/ components inside shadow dom, and need a way to inject those styles inside shadow dom. by default material-ui, which uses jss under the hood injects styles in the head of the page.
Is that even possible? Can anyone come with an example?
This is what my web component looks like, it is a web component that renders a react app that contains material-ui styles.
import * as React from 'react';
import { render } from 'react-dom';
import { StylesProvider, jssPreset } from '#material-ui/styles';
import { create } from 'jss';
import { App } from '#myApp/core';
class MyWebComponent extends HTMLElement {
connectedCallback() {
const shadowRoot = this.attachShadow({ mode: 'open' });
const mountPoint = document.createElement('span');
const reactRoot = shadowRoot.appendChild(mountPoint);
const jss = create({
...jssPreset(),
insertionPoint: reactRoot
});
render(
<StylesProvider jss={jss}>
<App />
</StylesProvider>,
mountPoint
);
}
}
customElements.define('my-web-commponent', MyWebComponent);
Setting the insertionPoint on jss to the actual react root inside the shadow root will tell jss to insert those styles inside that shadow root.
Using https://github.com/Wildhoney/ReactShadow to create shadow dom (you could also do it by hand as shown in previous answer), I created a small WrapperComponent that encapsulates the logic.
import root from 'react-shadow';
import {jssPreset, StylesProvider} from "#material-ui/styles";
import {create} from 'jss';
import React, {useState} from "react"
const WrappedJssComponent = ({children}) => {
const [jss, setJss] = useState(null);
function setRefAndCreateJss(headRef) {
if (headRef && !jss) {
const createdJssWithRef = create({...jssPreset(), insertionPoint: headRef})
setJss(createdJssWithRef)
}
}
return (
<root.div>
<head>
<style ref={setRefAndCreateJss}></style>
</head>
{jss &&
<StylesProvider jss={jss}>
{children}
</StylesProvider>
}
</root.div>
)
}
export default WrappedJssComponent
Then you just need to Wrap your app, or the part of your app you want to shadow inside <WrappedJssComponenent><YourComponent></YourComponent></WrappedJssComponenent>.
Be careful, some of the material-UI component won't work as usual (I had some trouble with
ClickAwayListener, maybe because it uses the parent dom, did not investigate more than that to be honest.
Popper, and everything that will try to use document.body as container will not have access to jss defined in shadow node. You should give an element inside the shadow dom as container.
There is also a whole page in the docs now (MaterialUI 5) that covers how to integrate MUI with a shadow-dom. You also might have to set Portal defaults not to target the dom. https://mui.com/material-ui/guides/shadow-dom/
When using #material-ui/core/CssBaseline with MUI, also emotion styles are being used. In order to support both legacy jss and emotion you can extend the accepted answer above with a CacheProvider like this:
import ReactDOM from 'react-dom/client'
import App from './App'
import createCache from '#emotion/cache'
import { CacheProvider } from '#emotion/react';
import { StylesProvider, jssPreset } from '#material-ui/styles';
import { create } from 'jss';
class ReportComponent extends HTMLElement {
constructor() {
super();
this.attachShadow({ mode: 'open' });
const mountPoint = document.createElement('div');
const emotionPoint = this.shadowRoot!.appendChild(document.createElement('div'));
const emotionCache = createCache({
key: 'report-component',
container: emotionPoint
});
const reactRoot = this.shadowRoot!.appendChild(mountPoint);
const root = ReactDOM.createRoot(reactRoot);
const jss = create({
...jssPreset(),
insertionPoint: reactRoot
});
root.render(
<StylesProvider jss={jss}>
<CacheProvider value={emotionCache}>
<App />
</CacheProvider>
</StylesProvider>
);
}
}
customElements.define('report-component', ReportComponent);
