Ethereum: Starting WebSockets Independent for Real Time Data
As a programmer working with cryptocurrency markets on Binanci or other exchanges, you are probably familiar with the importance of real data flow that will be informed about market trends. The popular solution is the use of Websockes, which allow two -way communication between customers and web servers. In this article, we will explore how to launch a web -cuto in Ethereum independently to collect candle information.
Challenges WebSocout on Ethereum
Before you sink into solutions, it is crucial to understand the challenges that come with the website on Etherem:
* Gas prices : Ethereum has a high gas price, which can lead to delay in web messages.
* Network congestion : As several customers are connected to the same final webSocout point, the network congestion is growing, leading to a slower data transmission.
* Limited support for WebSockeet : The latest version of the WebSockes Protocol is not fully accepted on Ethereum, limiting its use.
Solution: Using an independent webSocker server
In order to overcome these challenges, we will use a dedicated web server operating on an independent Ethereum node. This approach permits:
* Faster data transfer time
: Using a separate webSocout server, data transfer time are significantly reduced, which is ideal for real -time analysis.
* Conjunctioning a reduced network : with fewer customers connecting to the same endpoint, the networking of the network is minimized, improving general performance.
* Complete support of WebSocout -a : We will use the latest version of the WebSockes protocol, providing perfect integration with binance and other exchanges.
Configuring an independent webSocker server
To create an independent webSocout server on Ethereum, you will need:
- Ethereum knot: Install a fully tested and revised Ethereum node (eg parity or Hyperleder fabric) to manage WebSocout links.
- WebSocout.js Library : Include the website library.JS in your project for easy integration with basic websocout.
- server installation
: Configure an independent web server to listen to a particular connection (for example, 8080) and configuring security measures to protect against potential attacks.
Here’s an example of how you can implement this configuration:
`Javascript
Const Express = demand (‘Express’);
Const App = Express ();
Const WebSocket = requires (‘webSocket’). Server;
// Configuration of the server configuration
Const server = new websocout.server ({port: 8080});
// Management of websockeet connections received
app.get (‘/ws’, (req, res) => {
server.handleconnection (Req, res);
});
// Define a call to manage websocout messages
Handlemessage function (web -blade, message, return call) {
Console.log (received message: $ {Message});
// data processes as needed and send them back to customers
Websocout.send ("Received data!");
Iche
// Start the WebSocout Web server
server (8080);
Binance data collection
To collect Binance Sanch data using this independent webSocout server, you can use a library likeWS-ETHERTUMto set up WebSocout links with API.
Here's an example of how you can change your code to collect SENDECRY:
Javascript
Const WebSocket = requires (‘webSocket’). Server;
// Connect to the end point of Binance WebSocout
Const Connection = New WebSocout (‘WSS: //pi.binance.com/bs4’);
Connection.on (‘Open’, () => {
Console.log (“connected to Binance WebSocout”);
});
Connection.on (‘Message’, (Message) => {
if (Message.type === ‘pump’) {)
// Treat the Pump message and send it back to customers
Console.log (Pumping Data: $ {Message.Value});
Connection.send (‘Received data!
