Bunyan Streams Config Parser

While we can specify bunyan to log to stream like process.stderr and process.stdout, we can only pass the write stream object directly into bunyan. However, when we try to put the configuration into a configuration file or even environment variable, we cannot specify it to take string values like "process.stderr" or "process.stdout".

This small modules take an array of bunyan logging streams configuration and transform string from "process.stdout" and "process.stderr" to the actual standard output and standard error write stream respectively.

Usage

const bunyanStreamsParser = require('bunyan-streams-parser');
const bunyan = require('bunyan');
const logger = bunyan.createLogger({
  name: config.get('appName'),
  // you can load the array from your favorite config module
  streams: bunyanStreamsParser([{
    level: 'info',
    stream: 'process.stdout', // after parsing, it will become the actual process.stdout write stream
  }]),
  serializers: { err: bunyan.stdSerializers.err },
});
