Modification pour copier l'application statique dans le dossier de l'application html de FRP 1000

Modifier package.json en ajoutant une section postbuild :

{
  "name": "myapp",
  "version": "0.1.0",
  "private": true,
  "homepage": ".",
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.5.0",
    "@testing-library/user-event": "^7.2.1",
    "react": "^16.13.1",
    "react-dom": "^16.13.1",
    "react-scripts": "3.4.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "postbuild": "cp -r -f ./build/* /c/LocalSite900/htmls/testreact",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

Modification pour gérer des variables d'environnement pour configurer l'application

Par exemple, pour définir des URLs d'API différentes en production et développement

Créer un fichier ".env.development" et un fichier ".env.production" à la racine de l'application React

REACT_APP_NOT_SECRET_CODE=Sage FRP 1000 (development)

REACT_APP_NOT_SECRET_CODE=Sage FRP 1000 (production)

Remarque: les nom de variables doivent commencer par RACT_APP_

Dans un composant React tester la variable d'environnement :

import React from 'react';
import logo from './logo.svg';
import './App.css';

function App() {
  return (
    <div className="App">
      <header className="App-header">
        <img src={logo} className="App-logo" alt="logo" />
        <p>
          Edit <code>src/App.js</code> and save to reload.
        </p>
        <a
          className="App-link"
          href="https://reactjs.org"
          target="_blank"
          rel="noopener noreferrer"
        >
          Learn React for {process.env.REACT_APP_NOT_SECRET_CODE}
        </a>
      </header>
    </div>
  );
}
export default App;
