lspeasy / core/src / ConsoleLogger

Class: ConsoleLogger

Defined in: packages/core/src/utils/logger.ts:78

Logger implementation that writes to the process console with level filtering.

Remarks

This is the default logger used by LSPServer and LSPClient when no custom logger is provided. Set logLevel in ServerOptions / ClientOptions to control verbosity.

Never

NEVER use ConsoleLogger in a stdio LSP server (StdioTransport) — the LSP base protocol uses stdout as the message channel. Any console.log / console.info / console.debug output will corrupt the stdio stream. Use NullLogger or a file-based logger instead, and send diagnostic messages via window/logMessage notifications.

Example

import { ConsoleLogger, LogLevel } from '@lspeasy/core';
import { LSPServer } from '@lspeasy/server';

// Only emit errors and warnings
const server = new LSPServer({
  logger: new ConsoleLogger(LogLevel.Warn),
});
