You could just use one of those libraries. To get them working in Meteor, create a
/client). You may need to add the jquery package if you haven’t already (
meteor add jquery).
To use the plugin, you will need to call it from Template.templateName.onRendered() (explained here). For example, if using gridster:
this .$(".gridster ul").gridster().data('gridster');
That should do it. Someone actually created a wrapper package for gridster: https://atmospherejs.com/matteodem/gridster So you can even use that in which case you don’t need to add the plugin files or jquery yourself.
Let me know if you have any questions.
