Auxiliary and optional back end for the Convergent Personal Economy platform

Overview

This is a backend server built with node.js and express, that saves blockchain and IPFS data to a mongoDB database to enable faster display in the Convergent frontend application.

Architecture

When the server starts, it collects all existing personal tokens (that were created through the Convergent factory contract) and saves the corresponding data to a mongoDB database. The server then continues to listen to the relevant contracts and saves new economies as they are created or updated. It exposes 2 REST APIs for the frontend:

getEconomies

To get all saved economies and their associated IPFS data, send a GET request to localhost:3000/economies.

getEconomy

To fetch a single economy and its associated IPFS data, send a GET request to localhost:3000/economies/:tokenAddress

(For testing:) postEconomy

To test creating a new economy, you can send a POST request to localhost:3000/post. This will soon be deprecated, since only the token factory contract can create new economies.

Install

$ npm install

Run

$ npm start
