This module configures the http
and https
modules to raise logging events for every outgoing http request.
Any library or module that uses the default http
and https
modules will be captured. The primary use case is for
centrally adding logging to all outbound api calls to third-party services without needing to manipulate those modules.
The logger will capture request and response arguments as well as the body sent or received.
An example log object for a call to https://www.google.com
:
Request
{ protocol: 'https:',
slashes: true,
auth: null,
host: 'www.google.com',
port: null,
hostname: 'www.google.com',
hash: null,
search: null,

pathname: '/',
path: '/',
href: 'https://www.google.com/',
method: 'GET',
headers: { host: 'www.google.com' },
body: ''
}
Response

To enable logging events initialize the global logger:
var globalLog = require('global-request-logger');
globalLog.initialize();
This will now raise success
and error
events for every http or https request:
globalLog.on('success', function(request, response) {
console.log('SUCCESS');
console.log('Request', request);
console.log('Response', response);
});
globalLog.on('error', function(request, response) {
console.log('ERROR');
console.log('Request', request);
console.log('Response', response);
});
You may optionally disable logging using the end
function:
globalLog.end();
The initialize
function accepts an options argument that can configure logging.
- maxBodyLength - The maximum length (in bytes) to log for a request or response body.
Unit tests are provided and can be run via npm test
