VSCode JSON RPC

This npm module implements the base messaging protocol spoken between a VSCode language server and a VSCode language client.

The npm module can also be used standalone to establish a JSON-RPC channel between a client and a server. Below an example how to setup a JSON-RPC connection. First the client side.

import * as cp from 'child_process';
import * as rpc from 'vscode-jsonrpc/node';

let childProcess = cp.spawn(...);

// Use stdin and stdout for communication:
let connection = rpc.createMessageConnection(
	new rpc.StreamMessageReader(childProcess.stdout),
	new rpc.StreamMessageWriter(childProcess.stdin));

let notification = new rpc.NotificationType<string, void>('testNotification');

connection.listen();

connection.sendNotification(notification, 'Hello World');

The server side looks very symmetrical:

import * as rpc from 'vscode-jsonrpc/node';


let connection = rpc.createMessageConnection(
	new rpc.StreamMessageReader(process.stdin),
	new rpc.StreamMessageWriter(process.stdout));

let notification = new rpc.NotificationType<string, void>('testNotification');
connection.onNotification(notification, (param: string) => {
	console.log(param); // This prints Hello World
});

connection.listen();
