This Soapi.JS script, if abused is likely to provoke frowns from those whom you would like to see smiles.

Note: the dataset is only valid if the entire user base is pulled, and on just about any other site there are far too many users for the execution to be even remotely considered non-abusive or even remotely useful.

So - bottom line is: you could have figured it out yourself, so no harm in me posting it.

Let's just say it is an example of how to get cached/throttled paged results from the api with JavaScript.

OOPS Busted abusing the API!!!

 Dont try this on stack overflow or really any other site with more than a couple thousand users. Really

  • @geo - yea, all this line of code, Soapi.RouteFactory("api.stackapps.com", apiKey).Users().getPagedResponse( function(data) {/* data.items == all users on stackapps */ }); does is return an array of all the users on stackapps while observing a 1 minute cached duration and complying with the throttle guidelines.

Similar code for StackWrap4J:

List<Users> allUsers = new UsersList(
      new StackWrapper("api.stackapps.com"), 
      new UserQuery()
);

You can then iterate through allUsers and see their lastAccessDate. The currently released version will plow through the allowed calls per second, but v1.0.1 will properly throttle the requests.

    I just noticed you are using a composition paradigm rather that the more imperative syntax that most of us are. I think I like the way that looks and I can immediately see some benefits. It it the case that your UserQuery is simply a property bag with parameters and such
    – Sky Sanders

  • @code Yeah, we like it too. It seems to simplify worrying about all of the possible parameters for all of the different routes.

  • on second look, i wonder if your UserQuery could be characterized as a parameter bag?
    – Sky Sanders
    Commented Aug 16, 2010 at 23:02
  • @code, I'm not versed on design patterns...but, yeah. It's basically a parameter bag. (Not sure if that's a bad thing...)

  • not a bad thing at all - ultimately beneath the layers of abstraction in soapi, something similar is happening. Whereas you use UserQuery, I use UsersParameters and reading your code with my eyes painted a different picture, which I also found interesting.

C# / Soapi.CS

using Soapi.CS

Context.Official.StackApps.Users
    .PageSize(100).PageCount(0)
    .OrderByDescending(u => u.LastAccessDate)
    .ToList().ForEach(u =>
        Console.WriteLine("{0}\t{1}",
        u.LastAccessDate.FormatElapsedTime(), u.DisplayName));
