Is it possible to load new data from the database to node.js without restarting the server?

Question

Node.js

let messages; // получаю список из базы
knex.select().from('messages').timeout(1000).then(res => {
    messages = JSON.stringify(res);
});

router.get('/api', async (ctx, next) => {
    ctx.body = messages; // вывожу
});

If I add new entries to the database, then they are not loaded by refreshing the page, and the server must be restarted.
In php, c#, none of this is needed, all the unloading comes from the current database and I'm confused. Those. Do I need to close the connection every time?
And to make everything on one port loaded is not an option at all ??
or how do they work with this on node? Someone chooses chooses this as the main tool ...

There's nothing to just write code through the ass. Your data is received once, but you need to do the receiving inside the corresponding method, at least (I’ll omit about SOLID, etc. for now)
