# Aserto Node library drags in express dependencies for users on fastify

## Whats going on

The aserto-node library bundles express helpers, forcing express and its dependency tree on users who use fastify instead. The ask was for a version with just the gRPC clients.

## What actually fixes it

The team shipped exactly that as a new package: topaz-node, available at aserto-dev/topaz-node and on npm, which contains the directory client without the express helpers. The reporter confirmed it exists and works.
