🌲 Timber - Bunyan writable stream

New to Timber? Here's a low-down on logging in Javascript.

@timberio/bunyan

This NPM library provides a Bunyan writable stream that transmits logs to Timber.io via the @timberio/node logger.

Here's how to get started:

Installation

Install the Node.js Timber logger and the Bunyan stream plugin via NPM:

npm i @timberio/node @timberio/bunyan

Importing

In ES6/Typescript, import both the Timber logger class and the Timber Bunyan stream class:

import { Timber } from "@timberio/node";
import { TimberStream } from "@timberio/bunyan";

For CommonJS, require the packages instead:

const { Timber } = require("@timberio/node");
const { TimberStream } = require("@timberio/bunyan");

Creating a client/stram

You can create a client the usual way for @timberio/node, and then pass it into a new instance of TimberStream:

// Assuming you've imported the Timber packages above, also import Bunyan...
import bunyan from "bunyan";

// Create a Timber client
const timber = new Timber("api-key-here");

// Create a Bunyan logger - passing in the Timber stream
const logger = bunyan.createLogger({
  name: "Example logger",
  level: "debug",
  streams: [
    {
      stream: new TimberStream(timber),
    },
  ],
});

// Log as normal in Bunyan - your logs will sync with Timber.io!
logger.info("Hello from Bunyan");

Log levels

Timber will log at the debug level and above. Trace logs or any log level below 20 will be ignored.

The fatal log level is transformed to error in the Timber logger.
