bunyan-whatevs-stream

Wrap whatever function you like in such a way that you can use it as a bunyan stream.

Installation

npm install --save bunyan-whatevs-stream

Usage

The interface is straightforward. You give it a function or a Promise that resolves to the function you want it to do. For example, (and this would be a silly way to achieve the goal), but suppose you wanted to use this wrapper to console.log your messages. Try the following:

import bunyan from 'bunyan'
import createStream from 'bunyan-whatevs-stream'

const whatevs = Promise.resolve(console.log)

const logger = bunyan.createLogger({
  level: 'info'
, name: 'bunyan-whatevs-stream-silly-example'
, streams: [ { stream: createStream(whatevs) } ]
})

logger.info('Heya!') // This will end up putting 'Heya!' into stdout

Fun, right?

FAQ

1. Why would I wrap the function it in a Promise?

Because your whatevs may not be ready to go right when you set up the logger. Perhaps your function calls some system you haven't connected to yet. That's fine. Give it a Promise that resolves to your whatevs.
