feat: PKCE auth + CI/CD deploy
Some checks failed
CI/CD — Build & Deploy / Build & Deploy (push) Failing after 25s

- Frontend: PKCE flow (oauth.js, api.js centralized, cookie-based AuthContext)
- Backend: token introspection, cookies httpOnly, refresh endpoint
- Replaced localStorage JWT with httpOnly session cookies
- useSaveSync migrated to cookie auth
- cookie-parser added
- Gitea CI workflow (vps-runner pattern)

// CORS Handling: Why is the current code commented out and do I need to define specific allowed origins for my project?
// CORS (Cross-Origin Resource Sharing) is a security mechanism in web browsers that blocks requests from a different domain than the server.
// You may find the following magic line in forums:
// app.use(cors());
// You should NOT do that: such code uses the `cors` module to allow all origins, which can pose security issues.
// For this pedagogical template, the CORS code is commented out to show the need for defining specific allowed origins.
// To enable CORS and define allowed origins:
// 1. Install the `cors` module in the backend directory
// 2. Uncomment the line `const cors = require("cors");`
// 3. Uncomment the section `app.use(cors({ origin: [...] }))`
// 4. Be sure to only have URLs in the array with domains from which you want to allow requests.
// For example: ["http://mysite.com", "http://another-domain.com"]
const cors = require("cors");
// Trust reverse proxy (Apache on VPS)

/* ************************************************************************* */
// Request Parsing: Understanding the purpose of this part
// Request parsing is necessary to extract data sent by the client in an HTTP request.
// For example to access the body of a POST request.
// The current code contains different parsing options as comments to demonstrate different ways of extracting data.
// 1. `express.json()`: Parses requests with JSON data.
// 2. `express.urlencoded()`: Parses requests with URL-encoded data.
// 3. `express.text()`: Parses requests with raw text data.
// 4. `express.raw()`: Parses requests with raw binary data.
// Uncomment one or more of these options depending on the format of the data sent by your client:
// Cookie parser with signing
const cookieSecret = process.env.COOKIE_SECRET;
if (!cookieSecret) {
console.error("COOKIE_SECRET manquant — cookies non signés !");
}
app.use(cookieParser(cookieSecret));
// JSON body parser
app.use(express.json());
// app.use(express.urlencoded());
// app.use(express.text());
// app.use(express.raw());
/* ************************************************************************* */
// Cookies: Why and how to use the `cookie-parser` module?
// Cookies are small pieces of data stored in the client's browser. They are often used to store user-specific information or session data.
// The `cookie-parser` module allows us to parse and manage cookies in our Express application. It parses the `Cookie` header in incoming requests and populates `req.cookies` with an object containing the cookies.
// To use `cookie-parser`, make sure it is installed in `backend/package.json` (you may need to install it separately):
// npm install cookie-parser
// Then, require the module and use it as middleware in your Express application:
// const cookieParser = require("cookie-parser");
// app.use(cookieParser());
// Once `cookie-parser` is set up, you can read and set cookies in your routes.
// For example, to set a cookie named "username" with the value "john":
// res.cookie("username", "john");
// To read the value of a cookie named "username":
// const username = req.cookies.username;

// Production-ready setup: What is it for, and when should I enable it?
// The code includes commented sections to set up a production environment where the frontend and backend are served from the same server.
// What it's for:
// - Serving frontend static files from the backend, which is useful when building a single-page application with React, Angular, etc.
// - Redirecting unhandled requests (e.g., all requests not matching a defined API route) to the frontend's index.html. This allows the frontend to handle client-side routing.
// When to enable it:
// It depends on your project and its structure. If you are developing a single-page application, you'll enable these sections when you are ready to deploy your project to production.
// To enable production configuration:
// 1. Uncomment the lines related to serving static files and redirecting unhandled requests.
// 2. Ensure that the `reactBuildPath` points to the correct directory where your frontend's build artifacts are located.
// const reactBuildPath = `${__dirname}/../../frontend/dist`;
// // Serve react resources
// app.use(express.static(reactBuildPath));
// // Redirect unhandled requests to the react index file
