IoPcore Node

A IoP 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 IoP Core v6.0.0b3 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.

Install

npm install -g iopcore-node --unsafe-perm=true --allow-root

Prerequisites

• IoP Core v6.0.0b3 with support for additional indexing (see above)
• Node.js v0.10, v0.12, v4 or v5
• mongodb 2.6.x
• ZeroMQ (libzmq3-dev for Ubuntu/Debian or zeromq on OSX)
• ~20GB of disk storage
• ~1GB of RAM

Configuration

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

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

Create database

Enter MongoDB cli:

$ mongo

Create databse:

> use blockchaindb

Create user with read/write access:

> db.createUser( { user: "iquidus", pwd: "3xp!0reR", roles: [ "readWrite" ] } )

*note: If you're using mongo shell 2.4.x, use the following to create your user:

> db.addUser( { user: "username", pwd: "password", roles: [ "readWrite"] })

Syncing databases with the blockchain

sync.js (located in scripts/) is used for updating the local databases. This script must be called from the explorers root directory.

node scripts/sync.js

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

Please note that IoP Core v6.0.0b3 will be downloaded automatically. Once completed the iopd binary should be placed into the <iop-data-dir> folder specified during node creation.

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