mongokeys

A command-line tool and library that extracts the names of keys from a specified MongoDB collection. It iterates through all documents in the collection and returns a sorted list of unique keys.

Currently only top-level keys are supported.

Example

$ mongokeys -d test -c test
_id
keyA
keyB
keyC
$

Usage

The module exports a function getKeys, which takes a Collection object and a callback function that itself takes an error object and an array of strings.

The command-line tool mongokeys accepts the db, collection and uri parameters. collection is required. The database can be specified either with the db parameter, or as part of the uri (connection string). If no uri is specified, localhost is assumed. Use --help or no parameters for a more detailed explanation.
