I am using the following code to insert data into mongo and am wondering how to I wipe it all from the console so my page isn't all cluttered. I guess I would also like to know how to selectively delete as well so i could select ment name entries and delete them.

To erase it all:

meteor reset

To delete each one by query with the os console

meteor mongo
db.collectionname.remove({query})

Or you could just do it from your chrome/safari/firebug console if your collection is exposed to the client, which you could build a UI and use:

collectionname.remove({query})

Tip:

You can use regexp to speed up and remove sets of documents matching a regular expression. e.g if I want to remove all values containing 'the' for the field name. This will work in the mongo console, server and client.

collectionname.remove({ name : { $regex: 'the', $options: 'i' }});

The i option makes the query case insensitive.

Of course collecionname is just a placeholder for whichever collection you decide to hit down.
