I try to implement Sign in with Facebook to my app (next.js), which require me to put tag to my html file, but with next.js is not static page, so I don't have html file.
This says I should create /public/static/script.js and put my code something like this:
import Head from 'next/head';
import MyAwesomeComponent from '../components/mycomponent';
export default () => (
<div>
<Head>
<script type="text/javascript" src="/static/script.js"></script>
</Head>
<MyAwesomeComponent />
</div>
)
Is that the way to do it is it a good practice, or I'm doing it wrong

I'd like to add Google Analytics and Google Tag Manager on my web.
I'm trying to separate it as stages. (dev, prod)
_document.tsx
import Document, {Head, Main, NextScript } from 'next/document';
export default class MyDocument extends Document{
render(){
return (
<html>
<Head>
{/* ... */}
<script async src="http://www.googletagmanager.com/gtag/js?id=UA-XXXXXXXX-X"></script>
{/* ... */}
</Head>
<body>
<Main />
<NextScript />
</body>
</html>
);
}
}
What I expect
<script async src=`http://www.googletagmanager.com/gtag/js?id=${process.env.GTM_CONTAINER_ID}`></script>
I wanna use like above that.
Just like normal JSX, you use curly braces to embed a JavaScript expression in an attribute.
<script async src={`http://www.googletagmanager.com/gtag/js?id=${process.env.GTM_CONTAINER_ID}`}/>
I made two apps one is for angularjs and one is to react. Now the problem is I include the react build in angularjs app and try to initialize the '' component but when I run the code it says Test is not defined.
Can someone help me with this or give me any idea how I can get out of this problem.
React Component:
import React from 'react';
import ReactDOM from 'react-dom';
class Test extends React.Component {
render() {
return (
<div>
Hello
</div>
);
}
}
angular Js Code:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body ng-app="angular-app">
<div id="root"></div>
<script src="https://unpkg.com/babel-standalone#6/babel.min.js"></script>
<script src="https://unpkg.com/react#16/umd/react.development.js" crossorigin></script>
<script src="https://unpkg.com/react-dom#16/umd/react-dom.development.js" crossorigin></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.1/angular.min.js"></script>
<script src="react/dist/build.js"></script>
<script>
ReactDOM.render(<Test/>, document.getElementById('root'));
</script>
</body>
</html>
You should write the following code in your react app and then load your bundle file in angularJS app.
ReactDOM.render(<Test/>, document.getElementById('root'));
Thing is, you cannot use jsx inside browser, jsx is usually transpiled using Babel into JavaScript function calls.
So 1. <Test /> will never work inside browser, you need to Babel that.
You need to expose react to you angularjs, best way I can think of is
// In react, instead of exporting component, export a function that mount component in given HTML
Export default (elm) => ReactDOM.render(<Test/>, elm)
I'm kinda new to ReactJS and don't even know if it's possible but I want my react app to be working in the browser from the .html file. without the need for calling the server and have it, working, only that way. ( I don't mind having a server to serve it obviously) just need to be able to have by calling the .html file
the public/index.html file:
<head>
<meta charset="utf-8">
<script src="/my_library/my_library.min.js"></script> <!-- needed for the project in the same folder the index.html is -->
<title>Demo</title>
</head>
<body>
<noscript>
You need to enable JavaScript to run this app.
</noscript>
<div id="root"></div>
<!--
This HTML file is a template.
If you open it directly in the browser, you will see an empty page.
You can add webfonts, meta tags, or analytics to this file.
The build step will place the bundled scripts into the <body> tag.
To begin the development, run `npm start`.
To create a production bundle, use `npm run build`.
-->
</body>
</html>
the index.js (in src folder):
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import App from './App';
import './index.css';
ReactDOM.render(
React.createElement(App),
document.getElementById('root')
);
The App.jsx in the src folder
import * as React from 'react';
import './App.css';
import { MyContainer } from './components/MyContainer/index';
class App extends React.Component {
render() {
return (
<div className={ 'App' }>
<header className={ 'App-header' }>
<h1 className={ 'App-title' }>
</h1>
</header>
<MyContainer />
</div>
);
}
}
export default App;
PS: I have been able to add React to my file... But this particular component that I want to add only works with NPM Start. and as you can see in the index.html file shown above is says
This HTML file is a template.
If you open it directly in the browser, you will see an empty page.
which is exactly what I aim to change. if any one can provide some guidance or help about this, would be much appreciated.
If you just want to use React within an HTML file within a browser maybe you could just include the React library with a script tag as well as your custom React scripts with script tags as well. Their documentation has a nice example of just using React within an HTML file. I created a Codebox with their sample example for this below where the like button is using react. However, if you want to use JSX syntax you will have to use Babel, to transpile JSX into native JavaScript, and link the library like such:
<script src="https://unpkg.com/babel-standalone#6/babel.min.js"></script>
create_react_app gives you a lot of bells and whistles so you don't have to worry about setting up build configurations using tools such as webpack, babel, eslint, etc.. but this meant to give you a head start on building out an application so you can focus on the application itself and not configuration settings. Behind the scenes it's using webpack-dev-server to serve up your application, but for your use case I think it would be best to just add React as a script tag to an existing HTML page
'use strict';
const e = React.createElement;
class LikeButton extends React.Component {
constructor(props) {
super(props);
this.state = { liked: false };
}
render() {
if (this.state.liked) {
return 'You liked this.';
}
return e(
'button',
{ onClick: () => this.setState({ liked: true }) },
'Like'
);
}
}
const domContainer = document.querySelector('#like_button_container');
ReactDOM.render(e(LikeButton), domContainer);
<!DOCTYPE html>

Hopefully that helps!
I'm a project and that project have a "bootstrap" own, and i would want to import it for my render.
I created an archive HTML with the scripts:
<html>
<head>
<script> //1.www.s81c.com/common/v18/css/www.css</script>
<script> //1.www.s81c.com/common/stats/ida_stats.js</script>
<script> //1.www.s81c.com/common/v18/js/www.js</script>
</head>
</html>
and imported in my App.js:
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
***import './V18.html'***;
class App extends Component {
render() {
return (
<div className="App">
<header className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<h1 class="nameOfClassImported" className="App-title">BEM VINDX</h1>
</header>
To get started, edit <code>src/App.js</code> and save to reload.
</div>
);
}
}
export default App;
but given that error:
> Failed to compile.
./src/V18.html
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type.
| <html>
| <head>
| <script> //1.www.s81c.com/common/v18/css/www.css</script>
Resume:
I want to import scripts for i to use in my App.js
I think the tag for the .css file should be <link>.
There are multiple ways to import external scripts. One way that does work is to move these scripts to the <head> of your public/index.html.
/// public/index.html ///
<html>
<head>
<script src="//1.www.s81c.com/common/stats/ida_stats.js"></script>
<link href="//1.www.s81c.com/common/v18/css/www.css" rel="stylesheet">
<script src="//1.www.s81c.com/common/v18/js/www.js"></script>
/// rest of public/index.html ///
Those scripts will be downloaded when your page loads and you can access the variables in those scripts on the window object. After linking to these from your public/index.html, restart your React app, then open the console with F12 or Command-Option-i and type window into the console. There you will see all the global functions that are available from within your React app including window.IBMCore, window.Modernizr, etc
Have you tried this?
<script type='text/javascript' src='..//1.www.s81c.com/common/stats/ida_stats.js'></script>
and for following can you try a regular <link /> instead of <script>
import those in index.html path is public.index.html. Because your app put in one of div of same html page.
<script src="https://code.jquery.com/jquery-3.1.1.slim.min.js" integrity="sha384-A7FZj7v+d/sdmMqp/nOQwliLvUsJfDHW+k9Omg/a/EheAdgtzNs3hpfag6Ed950n" crossorigin="anonymous"></script>

Read this how webpack work.
https://webpack.js.org/configuration/externals/
else other way is save file and import at App.js
import './App.scss';
Im building a new React app but get the following error -
"require is not defined"
hello-world.html

import React from 'react';

import App from './App.jsx';
ReactDOM.render(

import React from 'react';
class App extends React.Component {

);
}
}
export default App;
Im running this from my client and don't have any web server running.
I tried to include http://requirejs.org/docs/release/2.2.0/minified/require.js
but it gives a totally different error.
You're trying to use a CommonJS module from within your browser.
This will not work.
How are you using them?
When you write import ... from ... in ES6 Babel will transpile these calls to a module definition called CommonJS and since CommonJS isn't around in the browser you'll get an undefined error from require().
Furthermore, you're also trying to load RequireJS which uses a different module definition pattern called AMD, Asynchronous Module Definition, and will not take care of the require calls for you. You can wrap them in RequireJS specific calls.
If you want to use CommonJS modules in your code base you need to first bundle them with either Browserify or webpack. The two tools will transform your require calls to some glue magic that you can use within the browser.
But in your specific case, if you remove the import calls and just let the browser take care of and attach the classes you've created to the window object your code should work.
Also, note that when you are using submodules from React without another transpiler you will have to reference the top-level modules. I just know that in some cases there are people who will not wish refactor their projects and alter directories to handle webpack/browserify module imports.
So instead of using the CommonJS import React, {useState, useEffect} from 'react' you can instead reference hooks with React.useEffect() , React.useState().
Just another solution for those who don't want to deal with any refactoring.
Here is a basic hello world example on hooks
The code samples on react website doesn't show the full html document. In summary use React.useEffect and React.useState. Get rid of the import statement.
<!DOCTYPE html>

function Example() {
const [count, setCount] = React.useState(0);
// Similar to componentDidMount and componentDidUpdate:
React.useEffect(() => { // Update the document title using the browser API
document.title = `You clicked ${count} times`; });
return (
<div>
<p>You clicked {count} times</p>
<button onClick={() => setCount(count + 1)}>
Click me
</button>
</div>
);
}
ReactDOM.render(
<Example />,
