What are @walletconnect/jsonrpc-utils's main functionalities?
Creating JSON-RPC Requests
This feature allows you to create a JSON-RPC request. The `formatJsonRpcRequest` function takes a method name and parameters, and returns a properly formatted JSON-RPC request object.
const { formatJsonRpcRequest } = require('@walletconnect/jsonrpc-utils');
const request = formatJsonRpcRequest('eth_sendTransaction', [{ from: '0x...', to: '0x...', value: '0x...' }]);
console.log(request);
Validating JSON-RPC Responses
This feature allows you to validate JSON-RPC responses. The `isJsonRpcResponseSuccess` function checks if a response is successful, while `isJsonRpcResponseError` checks if it contains an error.
const { isJsonRpcResponseSuccess, isJsonRpcResponseError } = require('@walletconnect/jsonrpc-utils');
const response = { jsonrpc: '2.0', result: '0x1', id: 1 };
console.log(isJsonRpcResponseSuccess(response)); // true
console.log(isJsonRpcResponseError(response)); // false
Handling JSON-RPC Errors
This feature allows you to create a JSON-RPC error response. The `formatJsonRpcError` function takes an id and an error message, and returns a properly formatted JSON-RPC error object.
const { formatJsonRpcError } = require('@walletconnect/jsonrpc-utils');
const error = formatJsonRpcError(1, 'Something went wrong');
console.log(error);
