Error While Deploying New React App - HTML, index.js the problem? - reactjs
Alright, ladies and gentlemen, I present to you the bain of my existence launching my first React web app portfolio for potential employers:
Creating an optimized production build...
Failed to compile.
Creating an optimized production build...
Failed to compile.
Error: HTML-webpack-plugin could not minify the generated output.
In production mode the html minifcation is enabled by default.
If you are not generating a valid html output please disable it manually.
You can do so by adding the following setting to your HtmlWebpackPlugin config:
|
| minify: false

See https://github.com/jantimon/html-webpack-plugin#options for details.

I have been writing this gigantic portfolio for several weeks, and when I deploy it, my nightmare begins. I hope and pray you guys can help or guide me to the solution. If any further code is needed, let me know. Thank you.
Edit - this is index.js:
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import './styles/style.css'
import './styles/images.css'
import './styles/no-touch.min.css'
ReactDOM.render(
<React.StrictMode>
<App />
</React.StrictMode>,
document.getElementById('root')
);

Not able to create an optimized build for my React app in the build folder
Actually, I ended up deploying it by deleting all node modules folders, doing what you said also, and reinstalling, this seemed to fix everything.

React dependencies in Sublime Text
I'm a beginner in React and has been working with the CDN links so far, I decided to remove these links and install the dependencies as it is better to work with, so I have tried to install the dependencies as instructed in the official website with npm install, and did so in my project repository, and after importing from react and react-dom the JS script doesn't work at all, and the console shows no errors, I tried a lot of fixes (including changing the source from index.js to index.pack.js), I also tried installing react using package control of Sublime Text, but nothing worked.
I don't think it's a code problem, but here are the index.html and index.js files :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<link rel="stylesheet" type="text/css" href="css/index.css">
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
</head>
<body>
<div id="root"></div>
<script src="js/index.js"></script>
<script src="js/bootstrap.min.js"></script>
</body>
</html>
//import React from 'react'
//import ReactDOM from 'react-dom'
const React = require("react");
const ReactDOM = require("react-dom");
const element = <h1 className="header">This is JSX</h1>
console.log(element)
ReactDOM.render(
element,
document.getElementById("root")
)
The css folder and files are all in the correct place and so is the index.js so it's not a path error, I think it's most likely a dependency error but it can be something else, does anyone have an idea on how to fix this, thanks in advance!
Sorry for the late reply as I have kinda solved the problem on the spot :D, indeed Create React App was the way to go, it builds the application nicely and it manages dependecies as well. Thanks for your answers !
firebase deploy empty page when accessing through link
New to react js and firebase
I have a firebase project, I did the init and deploy, but the index.html was a generic file.
I copied the index.html from the public directory in the build directory (which is the folder specified in hosting firebase.json)
when I start the app the page is empty.

that "root" bit might be the problem.

How to Add html in React
I'm starting to learn reactjs at the moment. I'm wondering how to add normal HTML-Tags in a react-app. Is i just possible to add them by using the render function or can I also just write normal HTML-Tags in my index.html file?
Cause when I'm doing so they're not displayed.
Just like:
const myelement = (<h1>some element</h1>);
ReactDOM.render(myelement, document.getElementById('root'));
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>
<div>
<div id="root"></div>
<div>just normal html</div>
</div>
Well, it works just fine here.. so there must be something wrong with my build..
If you're starting out, I recommend you bootstrap your apps using npx create-react-app. It'll give you a good sense of what a React app could look like, and some pointers for file structure.
Most React apps have an index.html file, which you can use like any normal HTML file. But, for the majority of your app, it's recommended to write your content in JSX (otherwise, you aren't getting the benefits of using React in the first place).
JSX
JSX looks very similar to regular HTML, with a handful of key differences:
Tag attributes tend to be in lowerCamelCase (onChange rather than onchange)
Instead of class (which is a reserved keyword in JavaScript), you need to use className
An Example Component
I've borrowed this sample code from React's official tutorial, which you should definitely check out if you haven't already.
This is a class Component, and your JSX goes inside of the render method:
import React from 'react';
class ShoppingList extends React.Component {
render() {
return (
<div className="shopping-list">
<h1>Shopping List for {this.props.name}</h1>
<ul>
<li>Instagram</li>
<li>WhatsApp</li>
<li>Oculus</li>
</ul>
</div>
);
}
}
What goes in index.html?
The only essential part of index.html is a <div id="root"></div>, which React will use to append the rest of the JSX.
This is also the place to add the usual metadata and icons.
As an example, here's the index.html file that comes with create-react-app. For most of my projects, I leave this pretty-much as-is:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<meta
name="description"
content="Web site created using create-react-app"
/>
<link rel="apple-touch-icon" href="logo192.png" />

</body>
</html>
In any given React component, there can only be one parent/top layer html element. You can get around this by using <React.Fragment> ...the rest of your html ... </React.Fragment> (or <>...</> depending on your version) or simply add a wrapping <div> around everything. JSX doesn't distinguish between "normal" html and "React" html, it just turns the React stuff into normal html (over simplification, but close enough for this question). Try it again and let me know if you encounter any problems.
const reactElement = (
<div>
React stuff
</div>
);
ReactDOM.render(
reactElement,
document.getElementById('root')
);

<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>
<div>

</div>

Cannot get reactjs-admin-lte to work with my reactjs project
I'm pretty new to this react/nodejs/bootstrap affair. I'm trying to make use of the reactjs-adminlte theme for bootstrap. I can get bootstrap widgets to work fine, such as buttons, but having trouble with this theme. The error I get is
React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object.

Would love to know why i cant get the Sidebar to display. Its probably something simple that im missing.
Thanks
maybe you should change:
import Sidebar from 'adminlte-reactjs';
to
import {Sidebar} from 'adminlte-reactjs';
or:
import adminlteReactjs from 'adminlte-reactjs';
let Sidebar = adminlteReactjs.Sidebar;
<Sidebar>

Building an webapp using react native
I am building an webapp using react native. I am very new to react native. I started to build an simple page but its give an error. I don't know where I did wrong. <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>React Tutorial</title> <link rel="stylesheet" href="css/style.css" /> </head> <body> <div id="header"></div> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.12.1/react.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.12.0/JSXTransformer.js"></script> <script src="scripts/header.js"></script> </body> </html> The above screenshot is of header.js. Where I did wrong could not understand. Help me out for any silly mistake. Thanks
Your file header.js contains JSX, which the browser doesn't understand. You need to transform your JSX file into JS before attempting to load it in the browser. One way to do this is to include browser.js (from Babel) and add the attribute type="text/babel" to your JSX script. Other options include using a tool such as Webpack with a loader that can pre-process your JSX before sending it to the client.
