Sortable/meteor/example

RubaXa:Sortable Meteor demo

This demo showcases the two-way integration between the reorderable list widget Sortable and Meteor.js. Meteor Mongo collections are updated when items are added, removed or reordered, and the order is persisted.

It also shows list grouping and control over what lists can give or receive elements. You can only drag elements from the list to the left onto the list to the right.

Usage

The example uses the local package from the checkout, so it needs to wire up some files (package.js and package.json). This is done by the handy run script:

Windows

git clone https://github.com/RubaXa/Sortable.git
cd Sortable
git checkout dev
cd meteor\example
run.bat

Elsewhere

git clone https://github.com/RubaXa/Sortable.git
cd Sortable
git checkout dev
meteor/example./run.sh

Prior art

Differential

Differential wrote a blog post on reorderable lists with Meteor and jQuery UI Sortable. It served as inspiration for integrating rubaxa:sortable, which uses the HTML5 native drag&drop API (not without its limitations). The reordering method used by the Differential example can lead to data loss though, because it calculates the new order of a dropped element as the arithmetic mean of the elements before and after it. This runs into limitations of floating point precision in JavaScript after <50 reorderings.

Todos animated

http://todos-dnd-animated.meteor.com/ (source) is based on old Meteor Blaze (back then Spark) API, and won't work with current versions. It does showcase some neat features, such as animation when collection elements are reordered by another client. It uses jQuery UI Sortable as well, which lacks some features vs. rubaxa:Sortable, e.g. text selection within the item.

TODO

• Animation
• Indication that an item is being edited
