good-bunyan

good-bunyan is a good reporter implementation to write hapi server events to a bunyan logger.

Install

npm install good-bunyan --save

Usage

new GoodBunyan(events, config)

Creates a new GoodBunyan object with the following arguments:

• events - an object of key value pairs.
  • key - one of the supported good events indicating the hapi event to subscribe to
  • value - a single string or an array of strings to filter incoming events. "*" indicates no filtering. null and undefined are assumed to be "*"
• config - configuration object with the following available keys:
  • logger (required): bunyan logger instance;
  • levels: object used to set the default bunyan level for each good event type. Each key is a good event (ops, response, log, error and request), and the values must be a bunyan level (trace, debug, info, error or fatal). Please note that good-bunyan will first try to look for a valid bunyan level within the event tags (e.g. using the tag ['error', 'handler'] will result in using the bunyan 'error' level);
  • formatters: object used to override the message passed to buyan. Each key is a good event (ops, response, log, error and request), and the values must be functions which take an object data as the argument and output either a string or an array of arguments to be passed to the bunyan log method. Default formatter functions can be found here.

Example

const Hapi = require('hapi');
const bunyan = require('bunyan');

const logger = bunyan.createLogger({ name: 'myapp', level: 'trace' });
const server = new Hapi.Server();

server.connection({ host: 'localhost' });

const options = {
  reporters: {
    bunyan: [{
      module: 'good-bunyan',
      args: [
        { ops: '*', response: '*', log: '*', error: '*', request: '*' },
        {
          logger: logger,
          levels: {
            ops: 'debug'
          },
          formatters: {
            response: (data) => {
              return 'Response for ' + data.path;
            }
          }
        }
      ]
    }]
  }
};

server.register(
  {
    register: require('good'),
    options: options
  },
  (err) => {
    if (err) {
      throw err;
    }

    server.route({
      path: '/',
      method: 'GET',
      handler: (request, reply) => {
        return reply({ 'hello': 'world' });
      }
    });

    server.start((err) => {
      if (err) {
        throw err;
      }

      server.log('info', 'Server started at ' + server.info.uri);
      logger.debug('tiago');
    });
  }
);

Example with custom msg

server.log('info', { msg: 'Server started', uri: server.info.uri };

good-bunyan complies with the good 7.x.x API.
