Quickly and elegantly add search, sort and pagination to your plural resource endpoints.

(function() {
  var assign;

  assign = require('lodash').assign;

  module.exports = function(route, req, res, pagination) {
    pagination = assign({}, pagination);
    if (pagination.page > 1) {
      pagination.previous = res.uri_for(route, assign(req.query, req.params, {
        page: pagination.page - 1
      }));
    }
    if (pagination.page < pagination.pages) {
      pagination.next = res.uri_for(route, assign(req.query, req.params, {
        page: pagination.page + 1
      }));
    }
    return pagination;
  };

}).call(this);
