Steem witness price feed publishing tool

Steem Witness Price Feed Publishing Tool

Install nodejs & npm

If you already have nodejs & npm installed you can skip this section, but I wanted to include it here for thoroughness. Run the following commands to install nodejs and npm in order to run the pricefeed software:

$ sudo apt-get update
$ curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash -
$ sudo apt-get install -y nodejs

Setup & Installation

Clone the project repo into the "pricefeed" directory and install using NPM:

$ git clone https://github.com/MattyIce/pricefeed.git pricefeed
$ cd pricefeed
$ npm install

Update the config.json file with your witness account name and private active key as described in the Configuration section below.

Run in background with PM2

I suggest using the PM2 software to manage and run your nodejs programs in the background. Use the following commands to install PM2 and run the pricefeed program:

$ sudo npm install pm2 -g
$ pm2 start feed.js
$ pm2 logs feed

If everything worked you should not see any errors in the logs and a price feed transaction should have been published to your account.

Run in Docker

If you prefer using Docker, use the following commands:

docker build -t pricefeed .
docker run -itd --rm --name pricefeed pricefeed

# Check the status with docker logs
docker logs pricefeed
