This package is an experiment that adds pagination to Meteor's standard subscriptions. It's a byproduct of the Telescope project.

Install via Meteorite:

$ mrt add paginated-subscription

This package makes available a single function Meteor.subscribeWithPagination. Like the built in Meteor.subscribe, it returns a handle, which should be used to keep track of the state of the subscription:

var handle = Meteor.subscribeWithPagination('posts', 10);

The arguments are as usual to Meteor.subscribe, with two exceptions:

1. The last argument must be a number, indicating the number of documents per page.
2. There's no support for a onReady callback, see TODO below.

The paginated subscription expects you to have a publication setup, as normal, which expects as a final argument the current number of documents to display (which will be incremented, in a infinite scroll fashion):

Meteor.publish('posts', function(limit) {
  return Posts.find({}, {limit: limit});
});

The important part of all this is the handle, which has the following API:

• handle.loaded() - how many documents are currently loaded via the sub
• handle.limit() - how many have we asked for
• handle.ready() - are we waiting on the server right now?
• handle.loadNextPage() - fetch the next page of results

The first three functions are reactive and thus can be used to correctly display an 'infinite-scroll' like list of results. Please see the telescope project for an example of real-world usage.

Contributions are heavily encouraged. The obvious things to fix are:

1. Allow an onReady callback
2. Do actual "pagination" rather than "infinite scroll" -- i.e. have an option to pass around an offset as well as limit.
3. Tests, tests, tests

Please contact me if you want to have a go at these and I'll be happy to help in what ways I can.
