luispablo-multilog v1.4.0
multilog
Simple wrapper for multiple loggers. Initially graylog and console.
Installation
npm install --save luispablo-multilog
Usage
First, get from anywhere you want some JSON with the properties. Such JSON must be an array with objects, with each object being a logger configuration.
For example, to get one console logger and one GrayLog logger use this:
const properties = [
{name: 'console', level: 'DEBUG'},
{
name: 'gelf',
level: 'WARN',
config: {
fields: {facility: "example", owner: "Tom (a cat)"}, // optional; default fields for all messages
filter: [], // optional; filters to discard a message
broadcast: [], // optional; listeners of a message
adapterName: 'udp', // optional; currently supported "udp" and "tcp"; default: udp
adapterOptions: {
protocol: 'udp4', // udp only; optional; udp adapter: udp4, udp6; default: udp4
family: 4, // tcp only; optional; version of IP stack; default: 4
host: '127.0.0.1', // optional; default: udp4
port: 12201 // optional; default: 12201
}
}
}
]
Logging levels
So far, we have INFO
, ERROR
, WARN
and DEBUG
. And they work as you would expect them to.
You must specify the level in each logger.
Then, create a MultiLog object:
const MultiLog = require("luispablo-multilog");
// ...
const log = MultiLog(properties);
and you're ready to go!
log.info("This is an info message");
// ...
const error = {code: 5, message: "Error message"}; // This can be anything you want
log.error(error);
and that's it, for the moment.
