RewriteEngine On

RewriteRule ^(.*)$ $1/ [L,R=301]

server {
    listen 80;
    server_name example.com;

    location / {
        try_files $uri $uri/ @rewrites;
    }

    location @rewrites {
        rewrite ^(.+)$ $1/ permanent;
    }
}

const express = require('express');
const app = express();

app.use((req, res, next) => {
    if (req.path.endsWith('/') || req.path === '/') {
        return next();
    }
    res.redirect(301, `${req.path}/`);
});

app.get('/', (req, res) => {
    res.send('Home Page');
});

app.listen(3000, () => {
    console.log('Server is running on port 3000');
});
