I'm struggling with the re-rendering issue in the SolidJS application. I have two routes, Home and Detail. A user can explore items in Home, and click the link on the item name to switch a page to Detail to check out detailed information.
export default function Home() {
const [items, setItems] = createSignal<Item[]>([]);
onMount(async () => {
setItems(
await fetchItemsThroughExpensiveAPI()
);
});
return (
<main>
<For each={items()}>
{(item) => (
<A href={`/item/${item.id}`}>{item.name}</A>
)}
</For>
</main>
);
}
export default function Detail() {
const params = useParams<{ id: string }>();
return (
<main>
// Some detailed information for the item ...
</main>
);
}
At this point, the API(fetchItemsThroughExpensiveAPI) will be called back when the user returns to the Home from Detail. I'm expecting this it is caused by re-rendering. How do I prevent re-rendering Home whenever a user returns to Home from another page to avoid unnecessary API calls?
Use a resource to fetch the data outside the Home component. If you need to fetch the data once during application's life, cache it.
https://www.solidjs.com/docs/latest/api#createresource
Lets make it more clear. There are different patterns to render async data, data that resides in a remote location.
Fetch as you render: In this pattern, data is fetched when the component mounts.
ComponentA below uses this pattern. Whenever it is re-rendered, data will be re-fetched.
Fetch then render: In this pattern, data is fetched outside the component, in one of its parent's scope. When component mounts it can use whatever is currently available, by whatever, I mean the request may not be resolved yet so state will be pending.
Resource API is build to make use of this pattern.
ComponentB below uses this pattern. Since data is fetched outside the component, re-rendering has no effect on it.
import { Accessor, Component, createSignal, Match, Switch } from 'solid-js';
import { render } from 'solid-js/web';
interface State { status: 'pending' | 'resolved' | 'rejected', data?: any, error?: any };
function getData(): Accessor<State> {
const [state, setState] = createSignal<State>({ status: 'pending' });
setTimeout(() => {
setState({ status: 'resolved', data: { name: 'John Doe', age: 30 } });
}, 1000);
return state;
};
const ComponentA = () => {
const state = getData();
return (
<Switch fallback={<div>Not Found</div>}>
<Match when={state().status === 'pending'}>
Loading...
</Match>
<Match when={state().status === 'resolved'}>
{JSON.stringify(state().data)}
</Match>
<Match when={state().status === 'rejected'}>
{JSON.stringify(state().error)}
</Match>
</Switch>
);
};
const ComponentB: Component<{ state: Accessor<State> }> = (props) => {
return (
<Switch fallback={<div>Not Found</div>}>
<Match when={props.state().status === 'pending'}>
Loading...
</Match>
<Match when={props.state().status === 'resolved'}>
{JSON.stringify(props.state().data)}
</Match>
<Match when={props.state().status === 'rejected'}>
{JSON.stringify(props.state().error)}
</Match>
</Switch>
);
};
const App = () => {
const state = getData();
const [show, setShow] = createSignal(false);
const handleClick = () => setShow(prev => !prev);
return (
<div>
{show() && (<ComponentA />)}
{show() && (<ComponentB state={state} />)}
<div><button onclick={handleClick}>Toggle Show Components</button></div>
</div>
)
};
render(() => <App />, document.body);
Here you can see it in action: https://playground.solidjs.com/anonymous/32518df5-9840-48ea-bc03-87f26fecc0f4
Here we simulated an async request using setTimeout. This is very crude implementation to prove a point. If you are going to fetch a remote resource, you should use the Resource API which provides several utilities like automatic re-fecthing when request parameters change.
There are few issues with your implementation. First and foremost, async data in never guaranteed to be received, so you should handle failures.
Since it takes some time to receive the remote data, you have to show the user some indicator of the ongoing request, like a loader.
If API call is an expensive operation, you have to cache the result, rather than forcing the UI not to re-render. In this sense, your approach is very problematic.
Utilize the useEffect hook. When the component is first loaded, the useEffect hook can be used to retrieve the items from the API and store them in a state variable. This way, when the component re-renders, it can access the stored items in the state variable instead of making a new API call.
export default function Home() {
const [items, setItems] = useState<Item[]>([]);
useEffect(() => {
async function fetchData() {
setItems(await fetchItemsThroughExpensiveAPI());
}
fetchData();
}, []);
return (
<main>
<For each={items}>
{(item) => (
<A href={`/item/${item.id}`}>{item.name}</A>
)}
</For>
</main>
);
}
So I'm very new to Gatsby, react, GraphQL, etc. In the past I've used pure CSS, HTML, and javascript to make my sites. Although, I was interested in Gatsby and the capabilities of it, so I decided to challenge myself and learn it.
I'm putting together a portfolio site for myself and for ease of updating, I would like to be able to add new projects through creating new folders, running a build script, and dropping the built site into my FTP.
This is how my folder structure for projects is set up:
-src
--projects
---1-daido-moriyama
----1-dm-frontcover.jpg
----2-dm-spread.jpg
----3-dm-backcover.jpg
----project-metadata.md
[...]
---2-lunch-from-a-care-package
----1-lf-wordmark.png
----2-lf-logo.png
----3-lf-poster.jpg
----project-metadata.md
[...]
The site is a single page, so no need to create new pages for each project. I just have them sorted into numbered folders because that would be the easiest to update for myself.
Ideally I would want to take the title and description from each project's markdown file, and put the title in an h3, the description in a p, and then display the images in a div, which when styled will become a carousel.
Mockup of the design
My current progress
I've been running some tests and have been able to access the markdown files using allMarkdownRemark, and the images using allImageSharp. It was hacky, but it worked, the only problem is that it was displaying all of the images, and not just the images needed for each project. Say, I have 8 images in a project, and 5 in another, it would display all 13 images.
Is there a way to do what I'm trying to do with Gatsby? Or should I just give up and move back to Jekyll…
gatsby-config.js:
module.exports = {
siteMetadata: {
title: 'J.C.R.'
},
plugins: [
'gatsby-plugin-react-helmet',
'gatsby-plugin-sass',
{
resolve: 'gatsby-source-filesystem',
options: {
name: 'projects',
path: `${__dirname}/src/projects/`
}
},
'gatsby-transformer-remark',
'gatsby-transformer-sharp',
'gatsby-plugin-sharp',
`#dream-bit-de/gatsby-plugin-better-page-tree`
]
}
gatsby-node.js:
const path = require('path')
module.exports.onCreateNode = ({ node, actions}) => {
const {createNodeField} = actions
if (node.internal.type === 'MarkdownRemark') {
const slug = path.basename(path.dirname(node.fileAbsolutePath, '.md'))
createNodeField({
node,
name: 'slug',
value: slug
})
}
}
Work component:
import React from 'react'
import { graphql, useStaticQuery } from 'gatsby'
import Img from 'gatsby-image'
const Work = () => {
const data = useStaticQuery(graphql`
query {
allMarkdownRemark(
sort: { order: ASC, fields: [frontmatter___position]}
) {
edges {
node {
frontmatter {
title
description
}
fields {
slug
}
}
}
}
allFile (
filter: {
ext: {eq: ".jpg"}
},
sort: {
order: ASC,
fields: [relativePath]
}
) {
edges {
node {
relativePath
relativeDirectory
name
ext
id
base
}
}
}
}
`)
console.log(data)
return (
<div id="work">
<ol>
{data.allMarkdownRemark.edges.map((edge) => {
return (
<li class={edge.node.fields.slug}>
<h3>{edge.node.frontmatter.title}</h3>
<p>{edge.node.frontmatter.description}</p>
{data.allFile.edges.map((edge) => {
return (
<img src={`../projects${edge.node.relativeDirectory}/${edge.node.name}-${edge.node.base}${edge.node.ext}`}></img>
)
})}
</li>
)
})}
</ol>
</div>
)
}
export default Work
index.js:
import React from 'react'
import Head from '../components/head'
import Info from '../components/info'
import Work from '../components/work'
import '../styles/index.scss'
const indexPage = () => {
return (
<div>
<Head/>
<Info/>
<Work/>
</div>
)
}
export default indexPage
I should dive deeper in the project to fully understand how you could handle that directly with the graphql query, but a short fix would be to filter out the images not related to the project.
{data.allFile.edge0s.filter((item) => item.name.includes(edge.node.frontmatter.id).map((edge) => {
return (
<img src={`../projects${edge.node.relativeDirectory}/${edge.node.name}-${edge.node.base}${edge.node.ext}`}></img>
)
})}
You will need to add a specific id on the name of your files related to the project so when you fetch them you filter out the one not related.
To be better, you could maybe format your imageSchema and add a specific property to handle the case so you won't need to format the image name and then instead of .includes() you could do item.myProperty === myCustomSchemaProperty.
It's much easier than you've tried so far. I would recommend using gatsby-image since all the images belong to the Gatsby ecosystem when you add the following:
{
resolve: 'gatsby-source-filesystem',
options: {
name: 'projects',
path: `${__dirname}/src/projects/`
}
},
Gatsby internally will parse everything inside /src/projects/ and will create nodes to make the schema available for GraphQL, so:
{
allFile(filter: {extension: {eq: "jpg"}}) {
edges {
node {
childImageSharp{
fluid{
...GatsbyImageSharpFluid
}
}
}
}
}
}
Then in your component just:
{data.allFile.edges.map((edge) => {
return <Img fluid={edge.childImageSharp.fluid} />
})}
I'm having difficulty with differences between client-side and server-side rendering of styles in Material-UI components due to classNames being assigned differently.
The classNames are assigned correctly on first loading the page, but after refreshing the page, the classNames no longer match so the component loses its styling. This is the error message I am receiving on the Console:
Warning: Prop className did not match.
Server: "MuiFormControl-root-3 MuiFormControl-marginNormal-4
SearchBar-textField-31"
Client: "MuiFormControl-root-3 MuiFormControl-marginNormal-4
SearchBar-textField-2"
I've followed the Material-UI TextField example docs, and their accompanying Code Sandbox example, but I can't seem to figure out what is causing the difference between the server and client classNames.
I experienced a similar issue when adding Material-UI Chips with a delete 'x' icon. The 'x' icon rendered with a monstrous 1024px width after refreshing. The same underlying issue being that icon was not receiving the correct class for styling.
There are a few questions on Stack Overflow addressing why the client and server might render classNames differently (e.g. need to upgrade to #Material-UI/core version ^1.0.0, using a custom server.js, and using Math.random in setState), but none of these apply in my case.
I don't know enough to tell whether this Github discussion might help, but likely not since they were using a beta version of Material-UI.
Minimal steps to reproduce:
Create project folder and start Node server:
mkdir app
cd app
npm init -y
npm install react react-dom next #material-ui/core
npm run dev
edit package.json:
Add to 'scripts': "dev": "next",

The problem is the SSR rendering in Next.js, which produces the style fragment before the page is rendered.
Using Material UI and Next.js (as the author is using), adding a file called _document.js solved the problem.
Adjusted _document.js (as suggested here):
import React from 'react';
import Document, { Html, Head, Main, NextScript } from 'next/document';
import { ServerStyleSheets } from '#material-ui/styles'; // works with #material-ui/core/styles, if you prefer to use it.
import theme from '../src/theme'; // Adjust here as well
export default class MyDocument extends Document {
render() {
return (
<Html lang="en">
<Head>
{/* Not exactly required, but this is the PWA primary color */}
<meta name="theme-color" content={theme.palette.primary.main} />
</Head>
<body>
<Main />
<NextScript />
</body>
</Html>
);
}
}
// `getInitialProps` belongs to `_document` (instead of `_app`),
// it's compatible with server-side generation (SSG).
MyDocument.getInitialProps = async (ctx) => {
// Resolution order
//
// On the server:
// 1. app.getInitialProps
// 2. page.getInitialProps
// 3. document.getInitialProps
// 4. app.render
// 5. page.render
// 6. document.render
//
// On the server with error:
// 1. document.getInitialProps
// 2. app.render
// 3. page.render
// 4. document.render
//
// On the client
// 1. app.getInitialProps
// 2. page.getInitialProps
// 3. app.render
// 4. page.render
// Render app and page and get the context of the page with collected side effects.
const sheets = new ServerStyleSheets();
const originalRenderPage = ctx.renderPage;
ctx.renderPage = () =>
originalRenderPage({
enhanceApp: (App) => (props) => sheets.collect(<App {...props} />),
});
const initialProps = await Document.getInitialProps(ctx);
return {
...initialProps,
// Styles fragment is rendered after the app and page rendering finish.
styles: [...React.Children.toArray(initialProps.styles), sheets.getStyleElement()],
};
};
This problem is related to MUI using dynamic class name which contain an ID. The IDs from the server side rendered CSS are not the same as the client side CSS, hence the mismatch error. A good start is to read the MUI SSR documentation
If you have this problem with nextjs (as I did) follow the example provided by the MUI team, which can be found here: material-ui/examples/nextjs
The most important part is in "examples/nextjs/pages/_app.js":
componentDidMount() {
// Remove the server-side injected CSS.
const jssStyles = document.querySelector('#jss-server-side');
if (jssStyles) {
jssStyles.parentElement.removeChild(jssStyles);
}
}
the related ticket can be found here: mui-org/material-ui/issues/15073
what it does, is remove the server side rendered stylesheet and replace it by a new client side rendered one
The issue is the server side generates the class names but style sheets are not automatically included in the HTML. You need to explicitly extract the CSS and append it to the UI for the server side rendered components. The whole process is explained here: https://material-ui.com/guides/server-rendering/
There is one other important, separate issue here: Material UI V4 is not React Strict Mode compatible. Strict mode compatibility is slated for version 5 with the adoption of the Emotion style engine.
Until then, be sure you disable React Strict Mode. If you're using Next.js, this is turned on by default if you've created your app using create-next-app.
// next.config.js
module.exports = {
reactStrictMode: false, // or remove this line completely
}
I had the same problem with Next.js and styled component, with the transpilation by Babel. Actually, the class names are different on the client and the server side.
Fix it in writing this in your .babelrc :
{
"presets": ["next/babel"],
"plugins": [
[
"styled-components",
{ "ssr": true, "displayName": true, "preprocess": false }
]
]
}
I met this problem on Material-ui V5. The solution to fix this problem is to make sure that class name generator needs to behave identically on the server and on the client.
so adding the code below in your _app.js:
import { StylesProvider, createGenerateClassName } from '#mui/styles';
const generateClassName = createGenerateClassName({
productionPrefix: 'c',
});
export default function MyApp(props) {
return <StylesProvider generateClassName={generateClassName}>...</StylesProvider>;
}
// 1 . Warning: prop classname did not match. Material ui with React Next.js
// 2 . Use your customization css here
const useStyles = makeStyles((theme) => ({
root: {
flexGrow: 1,
},
title: {
flexGrow: 1,
},
my_examle_classssss: {
with: "100%"
}
}));
// 3 . Here my Component
const My_Example_Function = () => {
const classes = useStyles();
return (
<div className={classes.root}>
<Container>
<Examle_Component> {/* !!! Examle_Component --> MuiExamle_Component*/}
</Examle_Component>
</Container>
</div>
);
}
export default My_Example_Function
// 4. Add name parameter to the makeStyles function
const useStyles = makeStyles((theme) => ({
root: {
flexGrow: 1,
},
title: {
flexGrow: 1,
},
my_examle_classssss: {
with: "100%"
},
}), { name: "MuiExamle_ComponentiAppBar" });
{/* this is the parameter you need to add { name: "MuiExamle_ComponentiAppBar" } */ }
{/* The problem will probably be resolved if the name parameter matches the first className in the Warning: you recive..
EXAMPLE :
Warning: Prop `className` did not match.
Server: "MuiSvgIcon-root makeStyles-root-98"
Client: "MuiSvgIcon-root makeStyles-root-1"
The name parameter will be like this { name: "MuiSvgIcon" }
*/ }
I like to share this mismatching case:
next-dev.js?3515:32 Warning: Prop className did not match. Server:
"MuiButtonBase-root MuiIconButton-root PrivateSwitchBase-root-12
MuiSwitch-switchBase MuiSwitch-colorSecondary" Client:
"MuiButtonBase-root MuiIconButton-root PrivateSwitchBase-root-12
MuiSwitch-switchBase MuiSwitch-colorSecondary
PrivateSwitchBase-checked-13 Mui-checked"
On client there are two more classes which means that the behavior on client-side is different. In this case, this component shouldn't render on server-side. The solution is to dynamically render this component:
export default dynamic(() => Promise.resolve(TheComponent), { ssr: false });
I had a problem with different classNames for client and server. I was using React, Material-UI, makeStyles and SSR (server-side rendering).
The error was:
Warning: Prop `className` did not match. Server: "jss3" Client: "App-colNav-3"
I spent several hours before I figured out that I had discrepancy in webpack mode for client and server. The scripts in package.json were:
"devServer": "webpack --config webpack.server.config.js --mode=production --watch",
"devClient": "webpack --mode=development --watch",
After I changed both to have development mode, the problem was solved :)
"devServer": "webpack --config webpack.server.config.js --mode=development --watch",
"devClient": "webpack --mode=development --watch",
If somebody is still struggling even after trying above solutions, Try this
If you have used noSsr prop in any of your components or theme, then remove it.
I had the following config in mui theme object, which was causing this problem.
import { createTheme, responsiveFontSizes } from "#mui/material/styles";
let theme = createTheme({
components: {
MuiUseMediaQuery: {
defaultProps: {
noSsr: true,
},
},
},
palette: {
mode: "light",
common: {
black: "#000",
white: "#fff",
},
primary: {
main: "#131921",
contrastText: "#fff",
},
secondary: {
main: "#fb6a02",
contrastText: "#fff",
}
}
})
RemovingnoSSr fixed all of the issues in my app including style mismatch between client and server.
The problem is cause by Nextjs server side rendering. In order to solve I do as following:
Make a component to detect whether is it from Client side
import { useState, useEffect } from "react";
interface ClientOnlyProps {}
// #ts-ignore
const ClientOnly = ({ children }) => {
const [mounted, setMounted] = useState<boolean>(false);
useEffect(() => {
setMounted(true);
}, []);
return mounted ? children : null;
};
export default ClientOnly;
Wrap my page component using ClientOnly component
export default function App() {
return (
<ClientOnly>
<MyOwnPageComponent>
</ClientOnly>
);
}
So the idea is, if it is client side then only render the component on the page. Therefore if current rendering is from Client side, render <MyOwnPageComponent>, else render nothing
In my case the issue happened because of different compilation modes of webpack for client-side code and server-side: client's bundle was generated by webpack using "production" mode, while server ran some SSR code from a package optimized for "development". This created a different "className" hash in styled-components in generateAndInjectStyles():
if (process.env.NODE_ENV !== 'production') dynamicHash = phash(dynamicHash, partRule + i);
So my fix was just to align the webpack modes.
You can add the name in anywhere you use makeStyles, like this:
const useStyles = makeStyles({
card: {
backgroundColor: "#f7f7f7",
width: "33%",
},
title: {
color: "#0ab5db",
fontWeight: "bold",
},
description: {
fontSize: "1em"
}
}, { name: "MuiExample_Component" });
I am not sure how it works, but I found it here: Warning: Prop `className` did not match ~ Material UI css arbitrarily breaks on reload
I'm also using NextJS + MUI v5 and I ran into this exact error right after merging Git branches. I suspect the merge corrupted something in the cache. I deleted the contents of .next/ and restarted the dev server and the error went away.
#Leonel Sanches da Silva's answer didn't work for me, as #material-ui/styles is deprecated, but using a snippet I found for another (non-material UI) project seems to have worked just fine for me:
Hat tip to Raul Sanchez on dev.to for the answer to this one.
Next doesn't fetch styled-components styles on the server, to do that you need to add this page to pages/_document.js:
import Document from 'next/document'
import { ServerStyleSheet } from 'styled-components'
export default class MyDocument extends Document {
static async getInitialProps(ctx) {
const sheet = new ServerStyleSheet()
const originalRenderPage = ctx.renderPage
try {
ctx.renderPage = () =>
originalRenderPage({
enhanceApp: (App) => (props) =>
sheet.collectStyles(<App {...props} />),
})
const initialProps = await Document.getInitialProps(ctx)
return {
...initialProps,
styles: (
<>
{initialProps.styles}
{sheet.getStyleElement()}
</>
),
}
} finally {
sheet.seal()
}
}
}
This code may update, so check Next's styled-components example for the latest.
I'm using Kendo UI & Angular 2 in a project, but cannot for the life of me seem to get the map widget to work with shapefiles in Angular 2.
It looks like I have to integrate with jQuery since the map component is not listed as an Angular 2 component yet. So, I've followed the instructions outlined here. However, it still doesn't seem to work. Here's what I currently have:
exampe.module.ts
...
import "#progress/kendo-ui";
...
example-map.html
<div #kendoMap style="height: 1000px;">
</div>
example-map.component.ts:
import { AfterViewInit, Component, ElementRef, OnDestroy, ViewChild } from '#angular/core';
declare var kendo: any;
#Component({
selector: 'example-map',
templateUrl: './example-map.html'
})
export class ExampleComponent implements AfterViewInit, OnDestroy {
#ViewChild('kendoMap')
kendoMap: ElementRef;
constructor () { }
ngAfterViewInit() {
const element = kendo.jQuery(this.kendoMap.nativeElement);
// This line throws an error
element.kendoMap({
controls: {
attribution: false,
navigator: false,
zoom: false
},
zoom: 7,
center: [32.7767, 96.7970],
layers: [
{
type: 'tile',
zIndex: -1,
urlTemplate: "https://#= subdomain #.tile.openstreetmap.org/#= zoom #/#= x #/#= y #.png"
},
{
type: 'shape',
style: { fill: { opacity: 0.7 } }
// shapefile layer data will be added here later by ajax
}
],
markers: []
});
}
ngOnDestroy() { kendo.destroy(this.kendoMap.nativeElement); }
}
This was throwing an error:
TypeError: Function has non-object prototype 'undefined' in instanceof check.
To fix that, I included the version of jQuery they were using in my index.html file:
<script src="http://code.jquery.com/jquery-3.3.1.slim.min.js"
integrity="sha256-3edrmyuQ0w65f8gfBsqowzjJe2iM6n0nKciPUp8y+7E=" crossorigin="anonymous"></script>
But now it's barfing about access 'width' off of something undefined.

Has anyone hit this before or know a great tutorial to use Kendo Maps w/ Angular 2+ ?
The issue with this was the order in which the component was rendering versus what was in the DOM. Moving the initialization into a jQuery block resolved the issue, like so:
ngAfterViewInit() {
kendo.jQuery(() => {
const element = kendo.jQuery(this.kendoMap.nativeElement);
...
});
}
The typical solution to the problem doesn't work in in React due to its dynamically generated component structure and event model, as opposed to traditional static HTML. I tried with react-iframe-resizer-super but not found perfect solution.
My code:
import React, {PropTypes} from 'react';
import ReactIframeResizer from 'react-iframe-resizer-super';
class Frame extends React.Component {
constructor() {
super();
}
componentDidUpdate() {
const iframeResizerOptions = {
// log: true,
// autoResize: true,
checkOrigin: false,
// resizeFrom: 'parent',
// heightCalculationMethod: 'max',
// initCallback: () => { console.log('ready!'); },
// resizedCallback: () => { console.log('resized!'); },
};
}
render() {
return (
<div style={{position: 'relative'}}>
<IframeResizer iframeResizerOptions={iframeResizerOptions}>
<iframe scrolling="no" src="https://en.wikipedia.org/wiki/Main_Page" allowfullscreen
style={{width:'100%', height:'100%'}}
}}></iframe>
</IframeResizer>
</div>
);
}
}
Then I got following error:
Uncaught ReferenceError: IframeResizer is not defined
Is there a way in React to set the height of an iframe to the height of its scrollable contents or is there any alternative way to archive this requirement?
I refer following link:
https://www.npmjs.com/package/react-iframe-resizer-super
This question is long decease, but I thought I would add just in case anyone else looking for clarification on using react-iframe-resizer-super + iframe-resizer (JS)
The problem in the code above is a misspelling of the imported component.
import ReactIframeResizer from 'react-iframe-resizer-super';
Should be:
import IframeResizer from 'react-iframe-resizer-super';
As you've used it inside your Frame component.
For those looking for clarification on using the library, here is my dead simple working solution:
Install dependencies on React project containing iFrame yarn add react-iframe-resizer-super iframe-resizer
Include iframeResizer.contentWindow.min.js on the page that you are using as the source of your iFrame.
Usage in React:
DynamicIFrame.jsx
import React from 'react';
import IframeResizer from 'react-iframe-resizer-super';
export const DynamicIFrame = props => {
const { src } = props;
const iframeResizerOptions = {
log: true,
// autoResize: true,
checkOrigin: false,
// resizeFrom: 'parent',
// heightCalculationMethod: 'max',
// initCallback: () => { console.log('ready!'); },
// resizedCallback: () => { console.log('resized!'); },
};
return (
<IframeResizer src={src} iframeResizerOptions={iframeResizerOptions} />
);
};
