ARCHIVIST APP

This guide is not for production ready Archivists, this is a product currently in development and will be updated often prior to mainnet release. For production-ready Archivists you will be able to download an npm package for use in your application.

Difficulty Level: Intermediate

Getting started with an XYO Archivist

An archivist in the XYO network serves as the data-layer component between the bridge and the diviner. It accepts and aggregates data from bridges and makes that data available to Diviners via a GraphQL API. In essence it is the scribe node of the XYO network.

As long as an archivist follows the protocols of the XYO network specified in the yellow paper they may implement the component however they wish.

Prerequisites

• You must have node installed If you don't, the easiest way to get node and npm is through

Homebrew

This is a package manager for Apple systems, for Linux systems use the package manager for your distro

We also recommend in most cases to use

NVM - Node Version Manager

This will allow you to manage multiple active node.js versions. This may also save you some installation headaches

Note We use the stable 10.15.3 node.js release.

• If you are using linux on ubuntu, you should use commands as the root by entering sudo su or you could run sudo prior to key commands. This guide will also prompt you for entering sudo when needed.

• You must have yarn installed: homebrew: brew install yarn or your Linux package manager

• You must have Lerna installed globally to use its CLI tool: npm install --global lerna

• Note if you are using ubuntu, you can install node and yarn with these helpful articles:

  • Installing node on ubuntu
  • Installing yarn on ubuntu

• You must have docker installled and running

  • There are instructions on how to install and run docker in the get started guide
  • Download the Docker Desktop for Mac for easiest entry
  • If you are using ubuntu, you'll need to use Docker CE
  • Make sure that docker runs throughout this process

• This node app wizard works macOS and Linux, and at this time this app is not Windows compatible
