## Connect to IPDB
This part explains, how to connect to IPDB testnet
(Good post https://medium.com/ipdb-blog/using-the-ipdb-test-network-a615f93d50a9)
1. Create an account in IPDB and retrieve an app id etc.
2. To connect to IPDB network you need your app_id & app_key. To get both, you need to register yourself in the following link https://developers.ipdb.io/signup
3. Once done,
```js
const API_PATH = 'https://test.ipdb.io/api/v1/'
const conn = new BigchainDB.Connection(API_PATH, {
app_id: 'your_app_id',
app_key: 'your_app_key'
})
```
### Connect to REST API + Websocket
https://docs.bigchaindb.com/projects/js-driver/en/latest/usage.html#websocket-event-stream-api-usage
If you are connecting to a node that has support for the Event Stream API, you will be able to access real-time event streams over the WebSocket.
Send a HTTP GET request to the node’s API Root Endpoint (e.g. http://localhost:9984/api/v1/) to check if the response the response contains a streams property:
```js
var wsUri = "ws://localhost:9985/api/v1/streams/valid_transactions";
function init() {
websocket = new WebSocket(wsUri);
websocket.onmessage = function(evt) { onMessage(evt) };
}
function onMessage(evt) {
writeToScreen('<a href="#" class="list-group-item"><h4 class="list-group-item-heading">Valid Transaction</h4><p class="list-group-item-text">' + evt.data + '</p></a>');
}
function writeToScreen(message) {
var pre = document.createElement("p");
pre.style.wordWrap = "break-word";
pre.innerHTML = message;
output.appendChild(pre);
}
/* Initialize websocket and attach all events */
window.addEventListener("load", init, false);
```
## Drivers and library
This part in the journey contains everything that needs to be downloaded to be able to write an application in BigchainDB/IPDB (drivers, library etc.) => shortest path to get started
Focus on JS driver in the beginning
Basecally you just need to install the driver, for JS:
```bash
$ npm install bigchaindb-driver
In case of python:
$ pip3 install bigchaindb_driver
```
