hyperledger-json-parsor

Fast, lightweight, Hyperledger JSON data parser developed by Xoriant Solutions Pvt. Ltd..

A wrapper/ adapter node.js script, which accepts a single parameter name and returns it’s value (single/ multiple), by consuming the underlying /metrics API output in real time and allows developers to create the necessary and well aligned simple API to feed all widgets.

Features

• Extensible – The solution can be extended to work for any other platforms which readily provide Prometheus-aligned multi-valued metrics values but the front-end requires a single parameter to be fetched.
• Data Parsing at Server Side – No need to write any client side code to parse data.
• Easy to configure – One time configurations through config files for host server details.

Installation

$ npm install hyperledger-json-parsor

var hyperJsonParser = require('hyperledger-json-parsor');
let inputData = {
        apiURL: 'YOUR_HOST_URL',
        parameter: 'PARAMETER_ID',
        recordType: 'multiple'
    }
let data = hyperJsonParser.getRemoteData(inputData);
    data.then(function (result) {
        //do your stuff
    }, function (err) {
        //error block
    })

inputData

The inputData argument allows you to customize the request with the following properties:

• apiURL: to define the GET API URL from which response is coming.
• parameter: to set specific key/parameter id to get values.
• recordType: to define single or multiple values required in response. Possible values are single, multiple.
