How to find the name of the symbol for Binance Websocket API using JavaScript
The Binance Websocket API provides real-time data flows for various cryptocurrencies and markets. One of the essential steps in the use of this API is to subscribe to specific symbol names, which allow you to receive updates on the price and market activity of a cryptocurrency or of a particular asset.
In this article, we will guide you throughout the search process of the name of the symbol of the Binance WebSocket API using JavaScript.
Prerequisite
Before diving into the code, make sure you have:
- Installed the “WS” package in your project (“NPM Install WS”) to manage Websocket connections.
- Creation of a new websocket connection to the Binance Websocket API by visiting [WSS: //Dex.binance.org/ws] (http: // wss: //dex.binance.org/api/ WS).
- Configure an account on Binance and obtained the key to secret api, which is required to authenticate with the websocket API.
Connection to Binance Websocket API
The code provided uses a websocket connection to subscribe to specific symbol names. Here’s 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 API {evt.data.url});
};
'
In this example,WSS: // Dex.binance.org / API / WSis the URL of the Binance Websocket API. When the connection is established (that is to say that an open event occurs), it records a message indicating the successful connection to the API.
Subscription to symbol names
To subscribe to specific symbol names, you can use theSUBSCRIBE () ‘provided by the Websocket API. The method Subscribe () 'takes four arguments:
- Method
: This specifies the operation to be carried out on the data received from the API.
- Thoict : This defines the subject or the ticker to which you wish to subscribe.
- Symbols
: This is a list of names of symbols separated by commas (for example, "BNB_BTCBTC").
Here is an example of a subscription request:
Javascript
Const Subonneraquest = {
Method: "Subscribe",
Subjects: ["kline_1h", "kline_4h"],
Symbols: ["BNB_BTCBTC"]
};
Conn.send (JSON.STRINGIFY (Abnunerequest));
'
In this code extract, we define an objectSubscription ‘with the specified parameters. The Subscribe method () 'sends a request to the Binance Websocket API with the details of the subscription.
Data management
Once you have subscribed to specific symbol names, you will receive updates on the price and market activity of these symbols in real time. To manage this data, you can use event headphones for WebSocket events (for example,open ',close', "message").
For example:
Javascript
conn.onmessage = function (evt) {
Const message = evt.data;
console.log (message);
};
` ‘
This code sets up a earpiece for all the incoming messages of the Websocket API. When a message is received, it records the console data.
Conclusion
The search for the name of the symbol of the Binance Websocket API using JavaScript involves connecting to the API, subscribing to specific symbol names and managing updates on the price and ‘Market activity of these symbols in real time. By following this guide and experimenting with the code extracts provided, you will be able to use the Binance Websocket API to create robust and effective applications.
