Configuration

If cnblogger.config does not exist, it will be created automatically with defaults on first use. You can also copy from cnblogger.config.example.

Create or edit a cnblogger.config JSON file in your project root (or set CNBLOGGER_CONFIG env var to a path). Example with databases:

{
  "mode": "all",
  "delimiter": "|",
  "file_dir": "./.logs",
  "file_same_day_mode": "append",
  "api_url": "https://log.example.com/ingest",
  "api_verify": true,
  "api_timeout_seconds": 3.0,
  "api_headers": {"Authorization": "Bearer <token>"},
  "db_sqlite_path": "./.logs/logs.db",
  "db_sqlite_table": "logs",
  "db_mysql": {"host": "localhost", "port": 3306, "user": "root", "password": "", "database": "logs", "table": "logs"},
  "db_postgres": {"host": "localhost", "port": 5432, "user": "postgres", "password": "", "database": "logs", "table": "logs", "sslmode": "prefer"},
  "db_mongo_uri": "mongodb://localhost:27017",
  "db_mongo_database": "logs",
  "db_mongo_collection": "entries",
  "colors": {"INFO": "cyan", "CRITICAL": "red", "ERROR": "bright_yellow", "WARN": "yellow", "DEBUG": "blue"},
  "timestamp_utc": false
}

• mode: cli | file | api | both (cli+file) | all (cli+file+api). Default: cli.
• file names: yyyymmdd.log (append by default on same day). If file_same_day_mode is new, files are yyyymmdd_HHMMSS.log.
• CLI format: [yyyy.mm.dd hh:mm:ss.mmm] [LEVEL] message (LEVEL colored, colors configurable).
• File/API/DB format stored consistently as ts|LEVEL|message or in columns.
• API verify: Set api_verify to true/false or a CA bundle path. Protocol is inferred from api_url.
• Databases:
  • SQLite: set db_sqlite_path and optional db_sqlite_table.
  • MySQL: set db_mysql object with connection details and table.
  • Postgres: set db_postgres object; optional sslmode.
  • MongoDB: set db_mongo_uri, db_mongo_database, db_mongo_collection.
