Cadex Node

A Cadex full node for building applications and services with Node.js. A node is extensible and can be configured to run additional services. At the minimum a node has an interface to Cadex Core (cadexd) v0.13.0 for more advanced address queries. Additional services can be enabled to make a node more useful such as exposing new APIs, running a block explorer and wallet service.

Usages

As a standalone server

git clone https://github.com/claprox/cadex-node
cd cadex-node
npm install
./bin/cadex-node start

When running the start command, it will seek for a .dashcore folder with a dashcore-node.json conf file. If it doesn't exist, it will create it, with basic task to connect to dashd.

Some plugins are available :

  • Insight-API : ./bin/cadex-node addservice @claprox/insight-api
  • Insight-UI : ./bin/dashcore-node addservice @claprox/insight-ui

You also might want to add these index to your dash.conf file :

-addressindex
-timestampindex
-spentindex

As a library

npm install @claprox/cadex-node
const cadex = require('@claprox/cadex-node');
const config = require('./cadex-node.json');

let node = cadex.scaffold.start({ path: "", config: config });
node.on('ready', function() {
    //Cadex core started
    cadexd.on('tx', function(txData) {
        let tx = new cadex.lib.Transaction(txData);
    });
});

Prerequisites

  • Cadex Core (cadexd) (v0.13.0) with support for additional indexing (see above)
  • Node.js v8+
  • ZeroMQ (libzmq3-dev for Ubuntu/Debian or zeromq on OSX)
  • ~20GB of disk storage
  • ~1GB of RAM

Configuration

cadexcore includes a Command Line Interface (CLI) for managing, configuring and interfacing with your Dashcore Node.

cadex-node create -d <dash-data-dir> mynode
cd mynode
cadex-node install <service>
cadex-node install https://github.com/yourname/helloworld
cadex-node start

This will create a directory with configuration files for your node and install the necessary dependencies.

Please note that Cadex Core needs to be installed first.

For more information about (and developing) services, please see the Service Documentation.

Add-on Services

There are several add-on services available to extend the functionality of Bitcore:

Documentation

  • Upgrade Notes
  • Services
    • Dashd - Interface to Cadex Core
    • Web - Creates an express application over which services can expose their web/API content
  • Development Environment - Guide for setting up a development environment
  • Node - Details on the node constructor
  • Bus - Overview of the event bus constructor
  • Release Process - Information about verifying a release and the release process.

Setting up dev environment (with Insight)

Prerequisite : Having a cadexd node already runing cadexd --daemon.

Cadex-node : git clone https://github.com/claprox/cadex-node -b develop Insight-api (optional) : git clone https://github.com/claprox/insight-api -b develop Insight-UI (optional) : git clone https://github.com/claprox/insight-ui -b develop

Install them :

cd cadex-node && npm install \
 && cd ../insight-ui && npm install \
 && cd ../insight-api && npm install && cd ..

Symbolic linking in parent folder :

npm link ../insight-api
npm link ../insight-ui

Start with ./bin/cadex-node start to first generate a ~/.cadex/cadex-node.json file. Append this file with "@claprox/insight-ui" and "@claprox/insight-api" in the services array.
