    Each request is a totally independent request that rebuilds the world. There’s no shared state (unless you want there to be).

    I with there was a language with this model, but without the language itself being completely garbage.

      Isn’t that the same as modern languages? For example in ASPCore / C#, you can just register all your services with a lifetime scoped to the request, and then there’s no shared state.

      If you want there to be a shared state, you’d just have to register your services with a higher lifetime scope, like with a singleton scope

      You can still use CGI with Apache. Apache will execute your program on each request and return its output from stdout as webserver response. If you have a form, it’ll get POSTed to stdin when Apache execute your program. You can write your program with whatever language you want as long as you can read stdin and write to stdout. It’s just tedious af so no one really use it these days. PHP was basically born because people got tired writing CGI program with pearl or C and want something more convenient. But with modern programming languages, perhaps CGI is not too bad, except the one process per request which will absolutely kill your server the moment you have visitors spike.

        You can’t use the CGI model with node and JS/Node because… unlike PHP, the thing isn’t designed for a quick start and shutdown.

          Why not? Is it because a typical nodejs app include hundreds of npm dependencies? As long as it can launch and finish within 60s (default timeout for apache), you should be able to use it.

                The point is that PHP is much more performant and doesn’t waste resources as NodeJS does. While you can run PHP on CGI with a decent bootstrap performance that won’t get people annoyed the same can’t be said of NodeJS. Nowadays people do PHP-FPM which is way faster at scaling up that any NodeJS process manager out there and doesn’t sit wasting resources when a particular application doesn’t have requests.

      And there is… its called PHP. JS doesn’t have this model because it is complete garbage slow and wouldn’t ever run fine and reasonable in that model.
