vscode-languageserver-protocol
Advanced tools
The vscode-languageserver-protocol npm package provides the necessary protocols to implement a language server that communicates with development environments like Visual Studio Code. It defines the protocol used between an editor or IDE and a language server that provides language features like auto-complete, go to definition, or find all references.
Defining Language Server Capabilities
This code sample demonstrates how to define the capabilities of a language server, such as synchronization, completion, and definition lookup.
{"capabilities": {"textDocumentSync": 1, "completionProvider": {"resolveProvider": true, "triggerCharacters": [".", "{"]}, "definitionProvider": true}}Handling Language Server Initialization
This code sample shows how to handle the initialization request from a client to a language server, specifying the process ID, root path, client capabilities, and trace settings.
{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"processId": null, "rootPath": null, "capabilities": {}, "trace": "off"}}Sending Diagnostics to the Client
This code sample illustrates how a language server can send diagnostics (such as errors or warnings) to the client for a specific document.
{"jsonrpc": "2.0", "method": "textDocument/publishDiagnostics", "params": {"uri": "file:///path/to/file", "diagnostics": [{"range": {"start": {"line": 0, "character": 0}, "end": {"line": 0, "character": 1}}, "severity": 1, "message": "Error message"}]}}monaco-languageclient is a package that allows the Monaco editor, which is the code editor that powers Visual Studio Code, to communicate with language servers using the language server protocol. It is similar to vscode-languageserver-protocol but is specifically tailored for the Monaco editor.
This npm module is a tool independent implementation of the language server protocol and can be used in any type of node application.
See here for a detailed documentation on the language server protocol.
