Websockets

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

JavaScript / TypeScript

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 is a popular library for working with web sockets in Python.

Example usage

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.
