Technology Stack

As a team of people using technology to make DLT products, it’s essential to be unambiguous about the technology/tools we use, so that everyone is clear what we all need to learn/use to make product(s) that are functional, fast, beautiful, usable and reliable!

ARK Core is written in TypeScript, and it has been using Lerna to manage the development and publication of its packages and uses Node.js as execution environment.

Development tools

The following development tools need to be installed on your machine to develop an application using ARK Core:

  • NodeJS - As ARK Core is written exclusively in NodeJS, the server-side framework for JavaScript, installing Node is a necessity for core development.
  • Hapi.js - A rich web framework for building applications and services. A base for our public REST API.
  • SocketCluster.io - SocketCluster is an open source real-time framework for Node.js. It supports both direct client-server communication and group communication via pub/sub channels. It is designed to easily scale to any number of processes/hosts. We use SocketCluster for the peer-to-peer communication enabling the blockchain protocol.
  • PostgreSQL - our “standard” database is Postgres. Postgres is the most “mature” Open Source Relational Database. It’s 100% Free (including all “advanced” features).
  • Lerna.js - A tool for managing JavaScript projects with multiple packages.
  • TypeScript - A language for application-scale of JavaScript. TypeScript adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript.

Operating System

While we have a strong preference for Linux (e.g. Ubuntu or CentOS), however we know that both Node.js and Postgres run on almost any environment including Microsoft Windows Desktop & Server.

All production and support tools are developed for Linux operating systems. We do not support Windows environment operating system in production. However it is still possible to develop your applications on a windows box.
