loopback-component-logger

Logging component for loopback using bunyan logger with additional loopback specific hooks and log management API

Note: Removing support for connector hook instrumentation given changes with loopback-context.

Features

• Default logger using bunyan
• Can use of custom bunyan streams to create root logger
• Hook: Basic performance instrumentation for remote execution
• Hook: Log management API (configurable)

Usage

Example server.js:

var loopback = require('loopback');
var boot = require('loopback-boot');
var rootLogger = bunyan.createLogger({name: 'myloopbackAPI'});
var logger = require('loopback-component-logger')(rootLogger);
var app = module.exports = loopback();
 

If rootLogger is not provide, the component creates a logger with default bunyan settings:

var loopback = require('loopback');
var boot = require('loopback-boot');
var logger = require('loopback-component-logger')();
var app = module.exports = loopback();
 

Child loggers can be created for model as shown below. By default child loggers inherit the log level from root.

 
var logger = require('loopback-component-logger')('TestModel');
module.exports = function(TestModel) {
    logger.debug('Initializing TestModel');
};
 

To add hooks and log management API to loopback, add configuration to component-config.json:

{
  "loopback-component-explorer": {
    "mountPath": "/explorer"
  },
  "loopback-component-logger": {
      "enableAPI" : true
  }
}
