sails-hook-bunyan

A sails hook replacing the Sails default logger with Bunyan. Supports sails 0.11.x.

For Sails 0.10.x support, see the old sails-bunyan.

Installation

To use, simply install the module.

$ npm install sails-hook-bunyan

Configuration

By default, sails-hook-bunyan is configured in the bunyan config object, however, this can be changed in your hook configuration.

module.exports.bunyan = {
  /** If true, a child logger is injected on each request */
  injectRequestLogger: true,

  /** If true, log uncaughtExceptions and terminate the process */
  logUncaughtException: false,

  /** If given, signal to listen on for file rotation */
  rotationSignal: null,

  /** Convenience setting to log to file */
  filePath: null,

  logger: {
    /** Logger name */
    name: 'sails',
    /** Bunyan logging level; defaults to info */
    level: null,
    /** Bunyan serializers */
    serializers: bunyan.stdSerializers,
    /** Array of output streams */
    streams: null
  }
};

By default, sails-hook-bunyan will log to stdout. If a filePath is specified, it will instead log to the named file. If both filePath and bunyan.streams are specified, the file stream is appended to the list of given streams.

For rotationSignal, it's recommended to use SIGHUP. SIGUSR1 is reserved by Node, and will start the debugger. SIGUSR2 is reserved by Sails, and will lower the sails app. Upon receiving the signal, sails-hook-bunyan will call bunyan.reopenFileStreams(); allowing for something like logrotate to handle the actual file rotation logic.
