I want to connect to the twelevedata
server through its provided socket connection to receive information.
import * as dotenv from 'dotenv'
import WebSocket from 'ws';
import express from 'express'
const app = express();
//setting up env
dotenv.config()
// setting up the websocket
const ws = new WebSocket(`wss://ws.twelvedata.com/v1/quotes/price?apikey=${process.env.API_KEY_TWELVEDATA}`);
const payload = {
"action": "subscribe",
"params": {
"symbols": "AAPL,INFY,TRP,QQQ,IXIC,EUR/USD,USD/JPY,BTC/USD,ETH/BTC"
},
}
ws.on('connection',function (steam) {
ws.on('open', (data) => {
console.log("data ==>",data);
ws.emit('subscribe',payload)
})
ws.on('subscribe', (data) => {
console.log("data ==>",data);
})
})
const port = process.env.PORT || 5000;
app.listen(port, () => {
console.log(`I am listening at ${port}`);
});
I created a websocket with my websocket connection on an express application but I am unable to receive any information from the twelvedata server regarding the subscribe
event that I have emitted !
This is how the websocket should work as shown by the twelvedata
website (look into the screen shots)
I am unable to connect and emit the subscribe
event given by the twelvedata's documentation
You don't want to emit
events from the websocket (that's for events you want to handle locally), but send
, ie, replace
ws.emit('subscribe',payload)
with
ws.send(payload)
// sending the parameters
ws.on('open', function open() {
ws.send(JSON.stringify(payload));
});
ws.on('message', function message(data) {
// receiving data
console.log('data ===>: ', JSON.parse(data));
});
ws.send
did the charm for me
