#Gappy for node.js Happy Google Analytics utility. Just provide your JWT, build your reports, and enjoy the response you receive. Uses the Google Analytics Reporting API v4.

Installing

npm install breachofmind/gappy

Or, if you're cool:

yarn add breachofmind/gappy

Usage

Fire and Forget approach

var gappy = require('gappy');

var options = {
    allResults: true,
    maxRequests: 10
};

gappy(require('./path/to/jwt.json'), options, function(Report) {

    return new gappy.Report("myFunReport", require('./path/to/report.json'));

}).then(gappy.toCSV).then(gappy.toColumns);

Anal approach

var gappy = require('gappy');

var options = {
    allResults: true,
    maxRequests: 10
};

var client = new gappy.Client(require('./path/to/jwt.json'));
var report = new gappy.Report("myFunReport", require('./path/to/report.json'));

client.add(report);

client.get().then(function(response) {
    // Do stuff!
    response.each(function(report,request,index) {
        // Whatever!
    })
});

// You could just pipe the response to the CSV generator.
client.get().then(gappy.toCSV);

Report Builder

Creating reports in Analytics V4 API is a pain. Gappy makes it easier.

var gappy = require('gappy');

const VIEW_ID = "12345678"; // From your GA account

var report = new gappy.Report('cityReport', VIEW_ID)
    .date("2016-10-01", new Date())
    .limit(20)
    .metric("sessions", "integer") // What??? no need for "ga:" ???
    .metric("bounceRate")
    .dimension("city")
    .dimension("country")
    .addTo(client);

// Clone an existing report to change stuff.
var cloned = report.clone('cityCloned').date('2015-10-01','2016-10-01',0);

Options

• allResults : Return the entire dataset if it is paginated. If your resultset has more than 10,000 records, it will keep querying until all the data is returned. Be careful with this one...
• maxRequests : Total number of requests to the API before stopping. Good if you are wary about querying the API too much for big data dumps.
