# Websockets

Plain text websockets run on port 50003 for BCH and 20003 for Nexa. The default port to use for [encrypted connection (wss)](ssl.md) is 50004 for BCH and 20004 for Nexa.

## JavaScript / TypeScript

[electrum-cash](https://www.npmjs.com/package/electrum-cash) is a decent library for working with electrum web sockets.

Example usage: <https://gitlab.com/dagurval/flipstarters/-/blob/master/src/electrum.ts>

## Python

[websocket-client](https://pypi.org/project/websocket-client/) is a popular library for working with web sockets in Python.


## Example usage


```Python
from websocket import create_connection
from time import sleep
import websocket 
import json

ws = create_connection("wss://bitcoincash.network:50004/") 

content = {
    "method": "blockchain.transaction.get",
    "params": ["ef6d2825e320a7e738240de3e8c7cec02aa86506baf3b142ed3e48d4614bd20a", True],
    "id": 0
}

ws.send(json.dumps(content).encode('utf-8')+b'\n')
sleep(0.5)

result =  ws.recv()

print(result)
ws.close()
```

**Response:**

Will be same as the response to the Javascript request above.
