✅ Creating random & unique page id

I want to generate id for a page that will be used to access it, something like example.com/2121424221. But generated id should have about 10-15 digits and be unique. How could I do that?

Do you have a list of IDs which you have generated already?

Sequential IDs masked with sqids Maybe nanoid with limited size and custom alphabet

The most trivial algorithm is do { id = GenerateRandomNumber(); } while (!AlreadyGenerated(id));

Or current UNIX timestamp + random value

I have Page table in my database Looks good to me. But how could I retrive list of ids from my db using EF?

Uh Like you would retrieve anything else?

var ids = await context.Things
    .Select(t => t.Id)
    .ToListAsync();

var ids = await context.Things
    .Select(t => t.Id)
    .ToListAsync();
