NodeJS API analytics using Google Analytics.
This module is Express middleware which utilizes the Analytics Measurement Protocol and sends statistics from received requests to Google Analytics.
As of now, the supported actions are:
The module also gathers as much data as possible to give meaningful insights. It supports the following parameters:
$ npm install api-ganalytics
var express = ;var Analytics = ;var app = ;var options =hostname : 'API-Ganalytics'userId : 'user' 'id'locale : 'user' 'locale'debug : false;app;app;app;app;
The palcement of the
app.use(); statements is critical for the availability of some features.
For example, the pageview
path property is only available after parsing of the request object, which is right after all custom middleware.
app.use(); statements must be placed BELOW the route decleration.
The initialization of the Analytics module can take place anywhere, as long as it happens before any features are used.
!!! Be sure to call
next(); on your routes in order to allow the execution of the middleware !!!
The module only hits the Google Analytics server when the environment variable
NODE_ENV is set to
NODE_ENV environment variable is unset or equals anything other than
production it will not fire any requests.
The exception to this is when
debug is set to
true in the options object. In that case the module will hit the debug endpoint and
output it's results.
The API-GAnalytics middleware accepts a dictionary of options allowing you to modify the inner workings. This section explains the individual options and their effects.
var options =hostname : 'API-Ganalytics'userId : 'user' 'id'locale : 'user' 'locale'debug : false;
The hostname will be used to set the
Data Source property of the action. Originally, this is
web for websites and
mobile applications. If this property is not set, it will default to
UserId is either a
string or an
array of object keys which will be used to fetch a numeric userId from the request object.
In this case, the
request object contains a
user object which has a field
id. A visual representation would look like this:
var request =// ...user :id : 1name : 'API-GAnalytics'// ...// ...
The userId will be used to traverse the request object until a destionation is reached.
Like the clientId, the locale option either is a
string or an
array of object keys which will be used to fetch a locale/language setting
from the request object.
Debug will put the module in debug mode. This means additional output where necessary and that the requests towards the Google
Analytics server will be redirected to their
/debug endpoint. This allows for checking if the request sent is valid.
By default, debug is
