Listing all collections in a mongo database within a nodejs script

I have found a few answers for listing collections in the shell but all the answers I have found for listing collections in a nodejs script seem to have been deprecated, answers like collectionNames and moongose.connection.db return has no method.

Solution

  • In the 2.0 version of the MongoDB driver for node.js you can use listCollections to get a cursor that contains the information of all collections. You can then call toArray on the cursor to retrieve the info.

    db.listCollections().toArray(function(err, collInfos) {
    // collInfos is an array of collection info objects that look like:
    // { name: 'test', options: {} }
});
