The package defines helpers that allow you to add tags to documents in your collections and render a list of tags within a template. Please note, that this package is still a work in progress and the API is very likely to change in the nearest future.

Supposing that you're developing your app with meteorite the only thing you need to do is:

mrt add tags

To add tags to selected collection use the Tags.TagsMixin routine:

MyCollection = new Meteor.Collection("myCollection");
Tags.TagsMixin(MyCollection);

You can now do stuff like this:

MyCollection.addTag('tagName', selector);
MyCollection.removeTag('tagName', selector);

By default the above actions are not allowed. To change this behavior you will need to allow actions on tags:

MyCollection.allowTags(function (userId) {
    // only allow if user is logged in
    return !!userId;
});

To search for all documents with a given tag use:

MyCollection.find({tags:'tagName'});

Now, you're ready to use tags within your views. Supposing you have a helper:

Template.myTeplate.data = function () {
    return MyCollection.findOne({...});
}

you can render tags attached to your data with {{renderTags}} helper:

{{#with data}}
  <ul class="...">
    {{renderTags}}
  </ul>
{{/with}}

Additionally, you have a read only access to Meteor.tags collection that keeps record about all tags existing in your database. The records are documents consisting of the following fields:

{
    collection : // name of the corresponding collection
    createdAt  : // the date, this tag was first used
    createdBy  : // userId
    nRefs      : // number of references
    name       : // name of this tag
}
