how to find a symbol name from the Binance Websocket Application Connection using Javascript

The Binance Websocket Application subscription offers Real -Time Data Feeds for a variety of cryptocurrency and markets. One of the most important stages of utilizing this application subscription is to order certain symbol names to help you receive updates on the price and market operation of a particular encryption currency or property.

In this article, we will guide you to find the symbol name of the Binance Websocket Application using Javascript.

Prerequisites

Before diving into the code, make sure you have:

  • Installed your project to handle websockets (NPM Install WS).

  • Created a new Websocket Connection to the Binance’s Websocket Connection by visiting [wss: //dex.binance.org/api/WS] (http: // wss: //dex.binance.org/pii/WS).

  • Set an account on the Binance Site and Get the “API Secret” key required to authenticate the websocket application.

Connection Binance Websocket API

The code provided uses the websocket connection to order certain symbol names. This is how it works:

`JavaScript

Const Conn = New Websocket ("WSS: //dex.binance.org/API/WS");

Conn.onopen = Function (EVT) {

Console.log (Connected to the Binance Websocket Application subscription $ {evt.data.url});

};

In this example, WSS: // dex.binance.org/API/WS is the url of the Binance Websocket. Once the connection is established (that is, an open event occurs), it is recorded in a message indicating a successful connection to the application subscription.

Ordering Symbol Names

To order certain symbols, you can use the “space)” method provided by the websocket application subscription. “Space)” Method Takes Four arguments:

  • Method : This defines the operation of the information received by the application subscription.

  • Subject : This defines the topic or ticker you want to order.

  • Symbols : This is a list of commas a list of symbols names (eg “bnb_BTCBTC”).

Here is an example of an order request:

`JavaScript

Const starcricerequest = {{

Method: "subscribe",

Topics: ["kline_1h", "kline_4h"],

Symbols: ["bnb_BTCBTC"]

};

Conn.send (json.stringify (subscriber));

In this clip of the code, we define the “subscriber” object with the specified parameters. The “Order)” Method Sends A Request to the Binance’s Websocket Subscription Subscription Information.

Processing of Data

Once you have ordered certain symbol names, you will receive updates on the price of these symbols and the operation of the market in real time. To process this information, you can use the event listeners for websocket events (eg “open, Close, "Message).

For Example:

`JavaScript

Conn.Onmessage = Function (EVT) {

Const Message = Evt.Data;

Console.log (message);

};

This code sets the listener on all arriving messages on the websocket application subscription. When the message is received, it is recorded in the console.

Conclusion

Finding a symbol of the Binance’s websocket application with JavaScript including communicating with the application interface, ordering certain symbol names and updates on the price and market operation of these symbols in real time. By following this guide and trying out the code snippets you have delivered, you can use the Binance’s websocket interface to build solid and powerful applications.
