@walletconnect/jsonrpc-ws-connection
Advanced tools
@walletconnect/jsonrpc-ws-connection is a package that provides a WebSocket connection for JSON-RPC communication. It is part of the WalletConnect protocol, which enables secure communication between decentralized applications (dApps) and wallets.
Establishing a WebSocket Connection
This feature allows you to establish a WebSocket connection to a specified URL. The code sample demonstrates how to create a new WSConnection instance, set up event listeners for 'open' and 'close' events, and open the connection.
const { WSConnection } = require('@walletconnect/jsonrpc-ws-connection');
const connection = new WSConnection('wss://example.com');
connection.on('open', () => {
console.log('Connection opened');
});
connection.on('close', () => {
console.log('Connection closed');
});
connection.open();
Sending JSON-RPC Requests
This feature allows you to send JSON-RPC requests over the established WebSocket connection. The code sample shows how to send a JSON-RPC request once the connection is open.
const { WSConnection } = require('@walletconnect/jsonrpc-ws-connection');
const connection = new WSConnection('wss://example.com');
connection.on('open', () => {
const request = {
jsonrpc: '2.0',
method: 'example_method',
params: [],
id: 1
};
connection.send(request);
});
connection.open();
Receiving JSON-RPC Responses
This feature allows you to receive and handle JSON-RPC responses from the WebSocket connection. The code sample demonstrates how to set up an event listener for 'message' events and parse the received JSON-RPC response.
const { WSConnection } = require('@walletconnect/jsonrpc-ws-connection');
const connection = new WSConnection('wss://example.com');
connection.on('message', (message) => {
const response = JSON.parse(message);
console.log('Received response:', response);
});
connection.open();
The 'ws' package is a simple to use, blazing fast, and thoroughly tested WebSocket client and server for Node.js. It provides a lower-level API compared to @walletconnect/jsonrpc-ws-connection, allowing for more flexibility but requiring more boilerplate code for JSON-RPC communication.
The 'json-rpc-ws' package provides a WebSocket transport for JSON-RPC 2.0. It offers similar functionality to @walletconnect/jsonrpc-ws-connection but is not specifically tailored for the WalletConnect protocol. It is a good alternative for general JSON-RPC over WebSocket use cases.
The 'rpc-websockets' package is a simple JSON-RPC 2.0 implementation over WebSocket. It supports both client and server implementations and provides a straightforward API for sending and receiving JSON-RPC messages. It is a versatile option for JSON-RPC communication over WebSocket.
