pull-paginate

Wrap a pull-stream, for pagination. This piece of logic lets you wrap the beginning and end of a stream, and also handle an empty stream. The intended use case is to render a stream to HTML while adding a "previous" hyperlink at the beginning, and a "next" hyperlink at the end, where those hyperlinks include information about the position of the stream at the first or last value respectively.

This module was factored out of git-ssb-web.

API

var paginate = require('pull-paginate')

• paginate(onFirst, transform, onLast, onEmpty): through. wrap a stream for pagination.

• onFirst(value, cb): given the first item in the source stream, callback a new item to prepend to the stream.

• onLast(value, cb): given the last item in the source stream, callback a new item to append to the stream.
• transform: through stream to transform the source values of the stream.
• onEmpty(cb): given an empty stream, callback an item to add to the stream. onEmpty gets called if and only if onFirst and onLast are not called.
