We are refactoring some legacy code into React and it turns out it is all reactNative.
Does anyone have any idea how we can refactor this AppRegistry.registerComponent into React (Just regular React (like the one create-react-app installs), not React Native, not React-Web), the same goes for AppRegistry.getApplication? We don't want ANY react-native at all, so any help would be greatly appreciated...
Could someone also point me at a decent resource so I can stop asking these asinine questions? :(
You will not need AppRegistry in your case. This is the entry point for your app in react native.
AppRegistry is the JS entry point to running all React Native apps.
App root components should register themselves with
AppRegistry.registerComponent, then the native system can load the
bundle for the app and then actually run the app when it's ready by
invoking AppRegistry.runApplication.
In your app, you should refactor
// react native app
import App from "./App";
...
AppRegistry.registerComponent(appName, () => App);
to
// your new app
import App from './App';
...
ReactDOM.render(<App />, document.getElementById('root'));

There is a ready front-end built using React.
Is it correct to connect it?
So far, there is only 1 page with one div block in which there are pictures. I read the documentation and didn't quite understand how it was done.
Can you please describe in detail all the steps to enable it?
I have a fresh/clean Laravel project. I don't know Laravel & React well yet. Therefore, I ask you to tell in detail and step by step all the actions so that React styles work in welcome.blade.php.
React structure (src/index.js):
import React from 'React';
import ReactDOM from 'react-dom/client';
import './index.scss';
import App from './App';
import 'macro-css';
const root = ReactDOM.creactRoot(document.getElementById('root'));
root.render(
<React.StrictMode>
<App/>
</React.StrictMode>
);
I tried to migrate the code from React index.js into Laravel's app.js and I threw all the other files next to it in the hope that it would work.
Please, first go through the Laravel Bootcamp which will take you through how Laravel integrates with React.
Writing Views In React / Vue
Our Breeze and Jetstream starter
kits give you a great
starting point for your next Laravel application powered by Inertia.
In addition, the Laravel Bootcamp
provides a full demonstration of building a Laravel application
powered by Inertia, including examples in Vue and React.
react beginner question...
I am learning react on my Mac and I installed NPM and node js and created a basic react app for testing.
In VS code app - when I type in terminal 'npm start' it opens a browser and shows the app running. - all good
Next I tried to upload the app to a live Web server (it has cpanel).
Seems like it is not connected to react - or somehow I need to start the app?
What can I do to start / connect it?
the URL is something like:
https://example.com/reactlearn/
or
https://example.com/reactlearn/public/
empty
or
https://example.com/reactlearn/src/
import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
const root = ReactDOM.createRoot(document.getElementById('root'));
Try deploying it to Vercel, Netlify or Heroku.
These should all provide free options with a url where you can see the app.
What's the best way to add Google Analytics to a Vite React project? I have added the gtag.js script into the index.html file within the Vite project. It does track users in Real Time but doesn't seem to track anything else. This makes me think the code should be in App.jsx instead...
Because when I go to GA I am getting the message saying there is No data received from my website yet.
I have looked into react-ga but this seems to only work with UA-XXX tags where as I am using GA v4 which uses IDs of G-XXXX
Has anyone added a v4 GA tag into a React project?
Update
Just found https://www.npmjs.com/package/react-ga4
This is how I have it now...
import React from 'react'
import ReactGA from 'react-ga4'
import {Helmet} from 'react-helmet'
import Footer from './components/base/Footer'
import Header from './components/base/Header'
import Form from './components/Form'
import Table from './components/Table'
ReactGA.initialize('G-XXXXXXX')
ReactGA.send('pageview')
function App() {
return (
...
But still getting the message "No data received from your website yet." in GA
It's best to use a vite plugin for that. Currently Vite-plugin-radar is available and it supports 7+ analytics providers ( Google Analytics, Google Tag Manager, Facebook Pixel, Linkedin Insight, Yandex Metrica, Baidu Tongji and Microsoft Advertising)
Another advantage with vite plugins is that mostly they are framework agnostic, so you can use them with Vue, React, Svelte or other vite supported frameworks.
I'm registering a service worker from create react app and I'm getting good scored in lighthouse for being a progressive web app and I can install the web app from the Chrome address bar, all is good
BUT when I update the content on the website nobody gets to see it unless they clear their cache, which they don't. How can I ensure they see the latest content while still getting a top score on lighthouse for being a progressive web app?
import React from 'react';
import ReactDOM from 'react-dom';
import * as serviceWorker from './serviceWorker';
import { Router } from './router';
import './scss/index.scss';
ReactDOM.render(<Router />, document.getElementById('shell'));
serviceWorker.register();
To service worker update your cache, you'll need to close ALL TABs of your website.
Another way is use this package to do this job.
https://www.npmjs.com/package/#loopmode/cra-workbox-refresh
It will do all the job for you, and after install the new files, it shows up a button allowing you to update the page
I have created a new reactjs project using create-react-app and am finding it's not working on IE10 & IE9. I have done a lot of research and it led me to using polyfills, which I have done with many of my other Rails on React app, but I'm finding it not working with this project created via create-react-app.
Here's the error:
SCRIPT5009: 'Map' is undefined
I notice this error is related to ES6's new Map() function.
So, here's what I've done in my code in an attempt to make it work:
import './polyfill';
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import { BrowserRouter } from 'react-router-dom';
import 'bootstrap/dist/css/bootstrap.min.css';
const app = (
<BrowserRouter basename={process.env.PUBLIC_URL}>
<App />
</BrowserRouter>
);
ReactDOM.render(app, document.getElementById('root'));
Polyfill.js:
import 'core-js/es6/map';
import 'core-js/es6/set';
import 'core-js/fn/object/assign';
This isn't working. I'm not sure what else to try. I've tried a lot of other polyfill imports as well and continue to get the same error.
Any help would be appreciated!
So, seeing as though create-react-app is what's restricting me from controlling the webpack config, I decided to take a different approach and build a fresh react app using webpack 4. I followed this article, https://dev.to/saigowthamr/how-to-create-a-react-app-from-scratch-using-webpack-4-1909.
This allowed me more control over the webpack config and now the polyfill loaders are working.
Nevertheless, if anyone has an explanation as to why it wasn't working with create-react-app, I think it'd be helpful for the community to know.
Thanks!
