What is vscode-languageclient?

The vscode-languageclient npm package is a library that helps in creating language clients for Visual Studio Code extensions. It facilitates communication between the client (VS Code) and the language server, enabling features like auto-completion, go-to-definition, and diagnostics.

What are vscode-languageclient's main functionalities?

Initialize Language Client

This code initializes a language client that communicates with a language server. The client is configured to listen to plaintext files and synchronize file events.

const { LanguageClient, TransportKind } = require('vscode-languageclient/node');
const client = new LanguageClient(
  'languageServerExample',
  'Language Server Example',
  {
    command: 'path/to/language-server',
    args: [],
    transport: TransportKind.stdio
  },
  {
    documentSelector: [{ scheme: 'file', language: 'plaintext' }],
    synchronize: {
      fileEvents: workspace.createFileSystemWatcher('**/.clientrc')
    }
  }
);
client.start();

Handle Server Notifications

This code sets up a handler for custom notifications sent from the language server to the client. It logs the received notification parameters to the console.

client.onReady().then(() => {
  client.onNotification('custom/notification', (params) => {
    console.log('Received custom notification:', params);
  });
});

Send Custom Requests

This code sends a custom request from the client to the language server and logs the server's response.

client.onReady().then(() => {
  client.sendRequest('custom/request', { text: 'Hello, server!' }).then((response) => {
    console.log('Received response:', response);
  });
});
