What is vscode-languageserver?

The vscode-languageserver package is designed to help developers create language servers for the Visual Studio Code editor. It provides the necessary APIs to implement language features such as auto-completion, go-to definition, or linting. This package is part of the Language Server Protocol (LSP), which standardizes the communication between editors or IDEs and language servers.

What are vscode-languageserver's main functionalities?

Initialization and Connection Setup

This feature allows the language server to establish a connection with the client (e.g., VS Code). The server listens for messages from the client to start providing language services.

{"createConnection": "require('vscode-languageserver').createConnection", "listen": "connection.listen()"}

Document Synchronization

Keeps the language server's document model in sync with the changes made in the editor. This is crucial for providing accurate language features.

{"onDidChangeTextDocument": "connection.onDidChangeTextDocument((change) => {})"}

Providing Completion Items

Enables the language server to provide context-aware completion suggestions (e.g., code snippets, method names) to the user.

{"onCompletion": "connection.onCompletion((textDocumentPosition) => { return [{ label: 'TypeScript', kind: CompletionItemKind.Text }]; })"}

Diagnostics

Allows the language server to send issues in the code (e.g., syntax errors, lint warnings) to the client, which can then display them to the user.

{"sendDiagnostics": "connection.sendDiagnostics({ uri: document.uri, diagnostics: [] })"}
