Sonarqube : Create a custom page using react - reactjs

Question

I would like to create a custom page using react but I cannot find the documentation to do this. On the Sonarqube documentation, there only the way to create a custom page using javascript only and I don’t understand how the example plugin works with react.
Can you tell me if there is a documentation that I can use.

Short answer: There isn't. There is barely anyone (no one in fact, as far as I've seen) using custom pages currently.
However, it IS possible. You need to create a react project with Webpack (or a similar JS packager).
I also recommend using Create-React-App. This fixes a lot of the setup for you. After that, in your index.js you use the example code from the SonarQube wiki.
Here is an example:
/*
PRODUCTION ENTRYPOINT
*/
import React from 'react';
import ReactDOM from 'react-dom';
import Project from './components/Project';
import './main.css';
window.registerExtension('myplugin/coverage', function (options) {
appendCustomCSS();
let isDisplayed = true;
window.SonarRequest.getJSON('/api/measures/component', {
component: options.component.key,
metricKeys: 'coverage'
}).then(function (response) {
if (isDisplayed) {
let obj = JSON.parse(response.component.measures[0].value);
let div = document.createElement('div');
render(obj, div);
options.el.appendChild(div);
}
});
return function () {
isDisplayed = false;
};
});
function appendCustomCSS() {
let fileref = document.createElement("link");
fileref.setAttribute("rel", "stylesheet");
fileref.setAttribute("type", "text/css");
fileref.setAttribute("href", "/static/myplugin/coverage.css");
document.head.append(fileref);
}
function render(objectArray, container) {
ReactDOM.render(<div className="Coverage"><Project objects={objectArray}/></div>, container);
}
