## Bitfinex Honey Framework Utilities

[![Build Status](https://travis-ci.org/bitfinexcom/bfx-hf-util.svg?branch=master)](https://travis-ci.org/bitfinexcom/bfx-hf-util)

This library hosts a set of utility functions used throughout the Bitfinex Honey Framework & API Libraries.

### Features

* Logic for processing Bitfinex candle data
* Helper for catching uncaught errors (`require('bfx-hf-util/lib/catch_uncaught_errors)`)

### Installation

```bash
npm i --save bfx-hf-util
```

### Quickstart

```js
const { preprocessRemoteCandles } = require('bfx-hf-util')
const { RESTv2 } = require('bfx-api-node-rest')

const rest = new RESTv2()
const candles = await rest.candles({
  timeframe: '1m',
  symbol: 'tBTCUSD',
  query: {
    start: Date.now() - (24 * 60 * 60 * 1000),
    end: Date.now(),
    sort: 1,
  }
})

// Fill in empty candles to generate a consistent dataset
const processedCandles = preprocessRemoteCandles('1m', candles)

// Do something with data
processCandles.forEach(candle => console.log(JSON.stringify(candle)))
```
