bfx-hf-models-adapter-lowdb

Bitfinex Honey Framework LowDB Adapter for Node.JS

This is an adapter around lowdb (a lodash-powered JSON database) for the Bitfinex Honey Framework. To use, initialize an instance of the bfx-hf-models database with it as an adapter.

Features

• lowdb saves the DB contents as a JSON file on disk
• No need to run a 3rd party database server instance
• Fully compatible with bfx-hf-models & the HF system (bfx-hf-data-server, bfx-hf-algo-server, bfx-hf-algo, etc)

Installation

npm i --save bfx-hf-models-adapter-lowdb
