This is a Hive Price Feed for witnesses on the HIVE Network. It's written in Node.JS and uses Hive's Hive-JS.

Recommended Node Version: Node 18

First, download the git repository, then edit config.json as needed. The interval is in minutes.

git clone https://github.com/Someguy123/hivefeed-js.git cd hivefeed-js cp config.example.json config.json nano config.json 

I recommend using Docker, however you can also use a locally installed copy of Node v8.11.4 or higher.

Starting Via Docker

# If you don't have docker installed yet, you can easily install it using run.sh ./run.sh install_docker # (Optional) To save a little time, you can use my binary docker image, instead of having # to build the container - which takes a few minutes (vs. a few seconds via binary install) ./run.sh install # Now just start your feed :) ./run.sh start # Check the logs / status to make sure it's working properly ./run.sh logs # Check the status with docker logs ./run.sh status # This will also help you check if it's running or not. # If you need to force update your feed at any point ./run.sh publish # Other useful commands: ./run.sh stop # To stop the hivefeed-js container ./run.sh restart # To restart the hivefeed-js container (e.g. after config changes) ./run.sh build # If you don't want to / can't use my binary image, this will force build a new image locally. 

Starting Via NodeJS (assuming you have the correct version installed)

npm install npm start

Easy update with Docker

To update the dockerised version simply do the following:

git pull ./run.sh install ./run.sh restart

{ "name": "your hive name", "signing_keys" : { "Public Signing Key" : "Private Signing Key" }, "network": "hive", "interval": 60, "peg": false, "peg_multi": 1 } 

• name (REQUIRED) - The name of the hive account that will publish the feed

• signing_keys (dictionary - alternative/combo to wif) - Witness signing keys as a dictionary {"pubkey": "privkey", ...}, can be used as either an alternative to wif, or in combination as backup keys

• node (default: https://api.deathwing.me/) - The HTTP(S) URL of the hive node to use, e.g. https://api.deathwing.me

• interval (default: 60) - The number of minutes between publishing the feed

• network (default: hive) - The network (chain) you're using this for. For using the hive long term testnet, set to testnet. Options are: hive testnet

• peg (default: false) - Set to true only if you want to adjust your price feed bias

• peg_multi (default: 1) - If "peg" is set to true, then this will change the "quote" to 1 / peg_multi. If you set "peg_multi" to 2 it will show a 100% bias on your feed.

NOTE: The settings ex_symbol, ex_compare, base_symbol and quote_symbol normally do not need to be adjusted.

Just set the correct network, and those settings will be automatically updated to the correct values.

wif - Your private active key if you'd use that instead. You can use this in replacement to signing_keys or alongside it.

ex_symbol - The symbol we're obtaining the price of. Default: hive

ex_compare - The symbol we're pricing ex_symbol with (i.e. the other half of the exchange pair). Default: usd

base_symbol - The symbol used for the "base": "0.512 HBD" part of the feed. Default: HBD

quote_symbol - The symbol used for the "quote": "1.000 HIVE" part of the feed. Default: HIVE

alternate_nodes - Alternate nodes to use if the main provided one is down. Provided as an array of nodes. Default : ["https://api.hive.blog", "https://api.deathwing.me"]

chain_id - Chain id of the chain that you are using. Default: beeab0de00000000000000000000000000000000000000000000000000000000

address_prefix - Address prefix of the chain that you are using. Default: STM

disable_exchanges - A list of exchange code 's to disable. Exchanges listed here will not be used directly (i.e. get price for A/B), nor indirectly (i.e. get price for A/D by converting A/C then C/D).

Example (disable all exchanges...):

{ "disable_exchanges": ["bittrex", "poloniex", "kraken", "ionomy", "binance"] }

exchanges_no_provide - Disable use of specific coin pairs per exchange, for example, you might want to temporarily ban the usage of HIVE/BTC from Poloniex.

Example (block HIVE/BTC from poloniex, block BTC/USDT on Kraken):

{ "exchanges_no_provide": { "poloniex": [ ["hive", "btc"] ], "kraken": [ ["btc", "usdt"] ] }, }

exchanges_provide - Add new coin pairs to exchanges, allowing the user to inform hivefeed-js of new pairs supported by a given exchange.

By default, most exchange adapters have the following pairs enabled (if the exchange supports them):

- BTC/USD - BTC/USDT - USDT/USD - HIVE/BTC - HIVE/USD (preferred over HIVE/BTC) 

Example (add BTC/DASH, EOS/USD, EOS/BTC to bittrex - add EOS/BTC to kraken):

{ "exchanges_provide": { "bittrex": [ ["btc","dash"], ["eos","usd"], ["eos","btc"] ], "kraken": [ ["eos", "btc"] ] } }
