    Insight Explorer

    A simple NPM Module to get data back easily from any coins Insight API server. Created as a more compatable "open" version, vs being locked to a specific coin.

    This module connects to a running Insight API service. If you're looking for information on how to run your own node, take a look at https://github.com/bitpay/insight-api.

    Installation

    To add the Insight Explorer to your project, just install it with your favorite package manager. For example, using the default NPM you can install it like this.

    npm install --save insight-explorer

    Usage Instructions

    To use the Insight explorer, first import the package into your node application.

    import { Insight } from 'insight-explorer'

    After you have imported the package, you will then need to create a new Insight object and give it your Insight API URL.

    let explorer = new Insight("https://livenet.flocha.in/api")

    If you would like to disable websockets, then you can pass false as the second paramater to creating a new Insight object. This will turn off Websocket updates. Websockets are default on.

    let explorer = new Insight("https://livenet.flocha.in/api", false)

    Now that we have created our Insight Explorer with the Insight API URL, we can query data from the blockchain.

    Block

    You can get a block back by querying based on its hash.

    explorer.getBlock("block_hash").then(function(block){
        console.log(block);
    })

    Block Index

    Get block hash by height

    explorer.getBlockIndex("block_height").then(function(block){
        console.log(block);
    })

    This would return:

    {
      "blockHash":"block_hash"
    }

    Raw Block

    explorer.getRawBlock("block_hash").then(function(block){
        console.log(block);
    })

    This would return:

    {
      "rawblock":"blockhexstring..."
    }

    Block Summaries

    Get block summaries by date:

    explorer.getBlockSummary(3, "2016-04-21").then(function(blocks){
        console.log(blocks);
    })

    Example response:

    {
      "blocks": [
        {
          "height": 408495,
          "size": 989237,
          "hash": "00000000000000000108a1f4d4db839702d72f16561b1154600a26c453ecb378",
          "time": 1461360083,
          "txlength": 1695,
          "poolInfo": {
            "poolName": "BTCC Pool",
            "url": "https://pool.btcc.com/"
          }
        }
      ],
      "length": 1,
      "pagination": {
        "next": "2016-04-23",
        "prev": "2016-04-21",
        "currentTs": 1461369599,
        "current": "2016-04-22",
        "isToday": true,
        "more": true,
        "moreTs": 1461369600
      }

    explorer.getTransaction("txid").then(function(tx){
        console.log(tx);
    })

    Address

    explorer.getAddress("address").then(function(addr){
        console.log(addr);

    Address Properties

    The four supported Properties that you can use are balance, totalReceived, totalSent, and unconfirmedBalance.

    explorer.getAddressProperties("address", "balance").then(function(prop){
        console.log(prop);
    })

    The response contains the value in Satoshis.
