@lucasnatoli/minimal-logger

File-based severity logger with log statistics. Zero internal dependencies.

• Logger class — writes {baseName}_{info|warn|error}.log under LOG_FOLDER (env, defaults to ./logs)
• Log statistics toolkit — parse log lines/files, count by time windows (1h…1m), save/load/discover {baseName}_stats.json
• logsRouter(app, { checkToken }) — optional Express router exposing /v1/logs/* endpoints (auth middleware injected by the host app)
• CLI: log-stats [--all | <baseName>...]

Install

npm install @lucasnatoli/minimal-logger

Usage

import { Logger } from "@lucasnatoli/minimal-logger";

const logger = new Logger("http");
logger.info("server", "listening on :3000");
logger.warn("server", "slow response");
logger.error("server", "boom");

Environment: LOG_FOLDER (default ./logs). Entry points should load dotenv themselves; this library never does.
