Alcoholic Beverages

Permits for the sale of alcoholic beverages in commercial establishments

Special Events

​

The system is designed for municipal staff with three distinct user roles:

  • Analysts - Create, edit, and review permit applications
  • Developers - System maintenance and configuration access

Key capabilities

​
Permit lifecycle management

Track permits from initial request through approval and issuance:
  • Create new permit applications with applicant information
  • Upload payment verification documents
  • Review and approve pending permits
  • Cancel permits with observation notes
  • Generate PDF reports for approved permits

​
Real-time updates

The system uses Socket.io to provide real-time synchronization across all connected clients: 
// Real-time permit creation notification
socket.on('publicidad:nuevo-permiso', async (data) => {
  await pool.query('SELECT * FROM permisos_publicidad WHERE codigo_permiso=?', 
    [data.permiso], (err, result) => {
      if (result.length > 0) {
        io.sockets.emit('publicidad:nuevo-permiso', result[0]);
      }
    });
});

​
Secure authentication

Built with bcrypt password hashing and express-session for secure user authentication: 
const bcrypt = require('bcryptjs');
const session = require('express-session');

// Session configuration
app.use(session({
  key: 'permisos_municipales_pass',
  secret: 'permisos_municipales',
  resave: false,
  saveUninitialized: false
}));
