filestream-logger

A Node.js file-based logger that automatically creates log directories and rotates files by date. Version 2.2.10 supports custom formatters, configurable directory and filename patterns, and extends multiple logger types. It provides synchronous and asynchronous file writing with queued directory creation. Different from Winston or Pino due to minimal dependencies (only Node.js fs module) and a simpler API focused on file logging. Release cadence is low; last release was in 2021. Ships TypeScript type definitions.
