Run Node
```
$(npm bin)/deocoincore-node start
```
The API endpoints will be available by default at: http://localhost:3001/deocoin-insight-api/

Add-on Services

There add-on service available to extend the functionality of Deocoincore:

Deocoin Explorer

Prerequisites

Note: You can use an existing Deocoin data directory, however txindex, addressindex, timestampindex and spentindex needs to be set to true in deocoin.conf, as well as a few other additional fields.

Query Rate Limit

To protect the server, deocoin-insight-api has a built it query rate limiter. It can be configurable in deocoincore-node.json with:

  "servicesConfig": {
    "deocoin-insight-api": {
      "rateLimiterOptions": {
        "whitelist": ["::ffff:127.0.0.1"]
      }
    }
  }

Or disabled entirely with:

  "servicesConfig": {
    "deocoin-insight-api": {
      "disableRateLimiter": true
    }
  }

Note: routePrefix can be configurable in deocoincore-node.json with:

  "servicesConfig": {
    "deocoin-insight-api": {
      "routePrefix": "insight-api",
    }
  }

Web Socket API

The web socket API is served using socket.io.

The following are the events published by insight:

tx: new transaction received from network. This event is published in the 'inv' room. Data will be a app/models/Transaction object. Sample output:

{
  "txid":"00c1b1acb310b87085c7deaaeba478cef5dc9519fab87a4d943ecbb39bd5b053",
  "processed":false
  ...
}

block: new block received from network. This event is published in the inv room. Data will be a app/models/Block object. Sample output:

{
  "hash":"000000004a3d187c430cd6a5e988aca3b19e1f1d1727a50dead6c8ac26899b96",
  "time":1389789343,
  ...
}

status: every 1% increment on the sync task, this event will be triggered. This event is published in the sync room.

Sample output:

{
  blocksToSync: 164141,
  syncedBlocks: 475,
  upToExisting: true,
  scanningBackward: true,
  isEndGenesis: true,
  end: "000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943",
  isStartGenesis: false,
  start: "000000009f929800556a8f3cfdbe57c187f2f679e351b12f7011bfc276c41b6d"
}

Example Usage

The following html page connects to the socket.io insight API and listens for new transactions.

<html>
<body>
  <script src="http://<insight-server>:<port>/socket.io/socket.io.js"></script>
  <script>
    eventToListenTo = 'tx'
    room = 'inv'

    var socket = io("http://<insight-server>:<port>/");
    socket.on('connect', function() {
      // Join the room.
      socket.emit('subscribe', room);
    })
    socket.on(eventToListenTo, function(data) {
      console.log("New transaction received: " + data.txid)
    })
  </script>
</body>
</html>
