The InfoJobs DevBoard backend is an Express server that reads its runtime settings from environment variables, falling back to sensible defaults defined in config.js. This keeps the codebase portable across development and production environments without requiring code changes.

​
Environment Variables

The following variables control the server’s runtime behaviour. Values in the Default column are used when the variable is not set.
VariableDefaultDescription
PORT1234HTTP port the Express server listens on
MODEL_AImistral/devstral-small-2AI model identifier exported from CONFIG in config.js
VITE_API_URL—Set in the frontend .env; should point to the running backend URL (e.g. http://localhost:1234)
The defaults are centralised in backend/config.js: 
export const DEFAULTS = {
  LIMIT_PAGINATION: 10,
  LIMIT_OFFSET: 0,
  PORT: 1234
}

export const CONFIG = {
  MODEL_AI: process.env.MODEL_AI ?? 'mistral/devstral-small-2'
}
LIMIT_PAGINATION and LIMIT_OFFSET are the fallback values used by the JobModel when no limit or offset query parameter is supplied.

​
npm Scripts

Run the following commands from the backend/ directory.
ScriptCommandDescription
devnodemon index.jsStarts the server and restarts on every file change — recommended during development
startnode index.jsStarts the server without hot reload — suitable for production
# Development (hot reload)
npm run dev

# Production
npm start

​
CORS

CORS middleware allows the React frontend — typically served by Vite on port 5173 — to make cross-origin requests to the Express API on port 1234. The codebase ships with a custom CORS middleware in middlewares/cors.js that restricts allowed origins to an explicit allow-list: 
import cors from 'cors';

const ACCEPTED_ORIGINS = [
  'http://localhost:5173'
]

export const corsMiddleware = ({ acceptedOrigins = ACCEPTED_ORIGINS } = {}) => {
  return cors({
    origin: (origin, callback) => {
      if (!origin) {
        return callback(null, true);
      }

      if (acceptedOrigins.includes(origin)) {
        return callback(null, true);
      }

      return callback(new Error('Origen no permitido'));
    }
  })
}
The current index.js entry point uses the open cors() helper (all origins) for convenience in development. Swap in corsMiddleware() when you need to lock down origins: 
// index.js — switch between open and restricted CORS
/* app.use(corsMiddleware()); */
app.use(cors());
When deploying behind a reverse proxy such as Nginx or Cloudflare, app.set('trust proxy', 1) is already configured in index.js. This ensures the rate limiter reads the real client IP from the X-Forwarded-For header rather than the proxy address.

​
Rate Limiting

The /ai router applies express-rate-limit to prevent abuse of the Ollama-backed AI summary endpoint. The limiter is scoped exclusively to that router and does not affect the /jobs endpoints. 
const aiRateLimiter = rateLimit({
  windowMs: 60 * 1000, // 1 minute window
  limit: 5,            // max 5 requests per IP per window
  message: { error: 'Demasiadas solicitudes, por favor intenta de nuevo más tarde.' },
  legacyHeaders: false,
  standardHeaders: 'draft-8',
})

aiRouter.use(aiRateLimiter);
When a client exceeds the limit, the server responds with HTTP 429 Too Many Requests and the message body above. The counter resets automatically after the 60-second window.
The rate limit counter is stored in memory. It resets whenever the server process restarts, so it does not persist across deployments.
The backend does not implement authentication. All endpoints — including job creation, update, and deletion — are publicly accessible without any credentials or API keys.
