@trusource/server

@trusource/server

Locally test smart contract calls to a TruSource provided oracle.

Getting started

$ npm install @trusource/server

Quick Start

After running a local ganache instance and migrating your contracts

const { server } = require('@trusource/server');

const model = require('./model.json');
const oracleArtifact = require('../build/contracts/Oracle.json');

server(oracleArtifact, model);

trusource.server

trusource.server(oracleArtifact, model);

Calling the server function initiates a process that listens for events emitted by a local ganache instance, fetches the requested data and makes contract calls, passing the response in the payload.

oracleArtifact

A build artifact generated for the oracle.sol smart contract after migration to a local ganache instance. From the root of truffle project, it is found at ./build/contracts/Oracle.json.

model.json

A model representing an api from a data source, can be found here.

Command Line Interface

Installing the package creates trusource-server command line utility, which can be used as follows.

$ trusource-server <path-to-Oracle.json> <path-to-model.json>
