What is vscode-jsonrpc?

The vscode-jsonrpc package provides a framework for implementing JSON-RPC based communication. It is primarily used for building language servers and other tools that need to communicate over JSON-RPC.

What are vscode-jsonrpc's main functionalities?

Creating a JSON-RPC connection

This code demonstrates how to create a JSON-RPC connection using the vscode-jsonrpc package. It spawns a child process and sets up a message connection using the standard input and output streams of the child process.

const { createMessageConnection, StreamMessageReader, StreamMessageWriter } = require('vscode-jsonrpc');
const { spawn } = require('child_process');

const childProcess = spawn('node', ['path/to/your/server.js']);

const connection = createMessageConnection(
  new StreamMessageReader(childProcess.stdout),
  new StreamMessageWriter(childProcess.stdin)
);

connection.listen();

Sending a request

This code demonstrates how to send a request over a JSON-RPC connection. The sendRequest method sends a request with a specified method and parameters, and returns a promise that resolves with the response.

connection.sendRequest('example/request', { param1: 'value1' }).then(response => {
  console.log('Received response:', response);
});

Handling notifications

This code demonstrates how to handle notifications over a JSON-RPC connection. The onNotification method registers a handler for notifications with a specified method.

connection.onNotification('example/notification', params => {
  console.log('Received notification:', params);
});

Handling requests

This code demonstrates how to handle requests over a JSON-RPC connection. The onRequest method registers a handler for requests with a specified method, and the handler returns a response.

connection.onRequest('example/request', params => {
  return { result: 'response' };
});
