Cradle (CouchDB+Node) routine to prepare a new DB, destroying the old one if it already exists. Good for prepping a data dump.

emptyDB.coffee

data =

  init: () ->
    data.emptyDB "animals", () ->
      console.log "ready"
      # now populate your new DB

  emptyDB: (name, done) ->
    db = new(cradle.Connection)().database(name);
    db.exists (err, exists) ->
      if exists
        db.destroy () ->
          console.log "destroyed the old one"
          db.create()
          done
      else
        console.log "no old one found"
        db.create()
        done

data.init()
