Worked well for me, thanks.
Very nice thanks
Very nice thanks
For me, the HTML renders, but the React button does not. Chrome tools reports an error on line 3 of the js file:
const e = React.createElement; // Uncaught ReferenceError: React is not defined.
What am I missing?
I tried a couple things I found to add to babel.config.js and the js, but no change:
- {
"presets": [
"@babel/preset-env",
["@babel/preset-react", {"runtime": "automatic"}]
]
} - import React from 'react';
Hi,
Which version are you using?
This one works well.
I am sure it suits well the first learners.
Thanks. I got the above example to work. Now, I want to convert it to Typescript. Do you have an example of how that could be done, possibly using Babel/Gulp in a build step?
Is it possible to use async/await via this methodology? Babel adds an import (babel-runtime/regenerator) to the first line of my transpiled javascript file, causing an error.
edit: I guess the better method would be to not use babel and just use React without jsx.
If I use the three lines of code from this page:
https://reactjs.org/docs/add-react-to-a-website.html
const domContainer = document.querySelector('#like_button_container');
const root = ReactDOM.createRoot(domContainer);
root.render(e(LikeButton));
The LIKE button does not appear on the html page.
But if I use just the last two lines in the downloaded js file the LIKE button does appear:
const domContainer = document.querySelector('#like_button_container');
ReactDOM.render(e(LikeButton), domContainer);
I don't know enough js/react to know what the above 3 lines does not work but the 2 lines does.
It is rather troubling especially when I am brand new to react and I am told that the react docs are the best place to learn react and I have flunked on the very first item....
nice
c'est vraiment génial
thanks
Has any one got a function component of Like Button,instead of class component, working in a straight HTML page ?
I don't think there's a way to get functional components to work. I used to use functional components until I started using React without JSX; I've totally switched over to using the class components.
thanks for support while the tutorial of react cn was out-date
Hi all.
@spicecoder yes here is it for function component:
'use strict';
const e = React.createElement;
function LikeButton(props) {
const [liked,setLiked] = React.useState(false)
if (liked) {
return 'You liked this.';
}
return e(
'button',
{ onClick: () => setLiked(true) },
'Like'
);
}
const domContainer = document.querySelector('#like_button_container');
const root = ReactDOM.createRoot(domContainer);
root.render(e(LikeButton));@andyhwong825 i always use function component. you can test the this code.
@Bobinio please which version of REACT are you using?
good one @okobsamoht , yes that's what I was thinking ,as long as we don't use JSX ,the dom rendring should able to handle both class and function components ; not sure why my first try did not work -any way thanks for confirming it does work.
HI,
Thank you for the example. I could get the example working as it is shown here.
In my case I have a prepackaged React component defined as JSX in project 1. I can do a production build of this project and import the js files in a website project. I am having trouble rendering the React component in the website project. The code in the website looks as follows
'use strict';
const btnContainer1 = document.querySelector('#button_container');
const btnroot = ReactDOM.createRoot(btnContainer1);
// this does not work. It gives console error "ExButton is not defined"
let element = <ExButton type="primary"></ExButton>;
// this works
// let element = <h1>Hello, world</h1>;
btnroot.render(element);
Any suggestion is appreciated.
@JVarghese99 ,I don't see you are importing ExButton component - please do
HI @spicecoder : thank you. I did try importing the ExtButton component in the above javascript but is gave error "require is not defined". I manged to get my example working by exporting the ExtButton in the reactjs project (window as any).ExButton = ExButton
Please see my complete example here https://dev.to/jvarghese/how-to-use-previously-packaged-reactjs-component-in-static-website-21be
@JVarghese99 ,firstly you need to make sure you can generate the component i.e you need to have the full stack of dependent components ,e.g your button component looks like a custom component as well ; once you can generate the component in a reactjs project, then build that project & you should have the right code along with the mimified js that you can bring to your static site
Ok
how to add a color to the 'You liked this' text?
Not working, I'm getting 'require' is not defined
@jo777750
here it is:
if (this.state.liked) {
return e(
'span',
{style:{color:"blue",background:"silver",fontSize:22}},
'You liked this.'
);
}
@Dipsaint1 can you show a screenshot?
@okobsamoht
Thank you for trying to help out.
I've found a solution.
@gaearon How to pass props in button component?
Hi I have resolved this bug, make sure the file name matches the React Component so e.g
<script src="like_button.js"></script>
file name in script must be like_button.js_ they must match and like button will appear
Thank you.
worked fine for me
