TCG Logger Module for Express
Built on Bunyan. Built-in Express middleware includes appending a child logger to each request and response times.
Usage
Add directly to the app object for an easy to access application-wide logger. Using the middleware will add a child logger as req.log for each request, as well as track and log response times. Each request logger gets assigned a UUID for easy request tracking.
const express = require('express'), Logger = require('tcg-logger'); const app = express(); app.log = new Logger(); app.use('/', app.log.middleware());Constructor API
Options are not required. Defaults to 'debug' log stream only.
const log = new Logger({ // Debug for human readable logs to stdout, false to disable stdout, and json for ...well... json logStream: <'debug', 'json', false>, // Pass a string absolute path for logging to a file, leave empty to disable logFile: '/absolute/path/to/logfile', // Name to give the logger logName: 'TCG Logger', // Minimum log level - defaults to 'debug' for debug streams, 'info' for all others logLevel: <'debug', 'info', 'warn', 'error'>, // Custom Bunyan serializers - see https://github.com/trentm/node-bunyan#serializers for docs reqSerializer, resSerializer, errSerializer});
