Info Server

Info-server is a NodeJS server responsible for maintaining an off-chain replica of the DigixDAO storage contracts. Essentially, it watches for newly mined Ethereum blocks and updates its own database.

Setup

Prerequisites

• MongoDB
• Ganache (Ethereum RPC client for development/testing)
• DigixDAO Contracts

Run info-server

• Get the source

$ git clone https://github.com/DigixGlobal/info-server.git
$ git checkout develop

• Install dependencies

$ npm install

• Run MongoDB

$ sudo service mongod start

• Run info-server

  Info-server can be started with multiple configurations, that are included in the development.config.js file. A few npm scripts have been added in the package.json file, also listed below:

  • Forcefully drop database and restart info-server with a fresh instance. This also starts watching blocks from the START_BLOCK config value.

  $ npm run dev:force
  

  • Re-sync all transactions from the blockchain, and then process them. This does not drop the database.

  $ npm run dev:resync
  

  • Only re-process the transactions that already exist in the database. You may want to choose this option if you have modified certain logic in the scripts/ directory, but do not want to re-sync all transactions from the blockchain

  $ npm run dev:reprocess
