GA-protocol - Javascript Wrapper of Google Analytics Measurement Protocol

For some hybrid apps(e.g uni-app), it's difficult to use native Google Analytics SDK. This project will help you to construct your data and manually send it to Google Analytics based on the measurement protocol provided by Google.

Installation

npm install @linusmelb/ga-protocol

Usage

/**
 *  Example usage
 */
import { GA } from '@linusmelb/ga-protocol';
const ga = new GA('UA-XXXXXXXXX-X');

// Optinal
// Default user-agent: ga-protocol/1.0.0
// Default client-id: 0. It should be a random UUID (version 4) as described in http://www.ietf.org/rfc/rfc4122.txt
ga.setUserAgent('ga-protocol/1.0.0'); // Optinal. 
ga.setClientId('123e4567-e89b-12d3-a456-426655440000');    

// Pageview 
// To debug, go to https://analytics.google.com/analytics/web -> realtime -> Content
await ga.pageView({
    hostname : 'http://localhost',
    pagePath : '/index',
    pageTitle: 'Hello World',
    cd1      : 'Android', // e.g. System
    cd2      : 'English', // e.g. Language
    // you can add more custom dimensions below... 
});

// Event 
// To debug, go to https://analytics.google.com/analytics/web -> realtime -> Events
await ga.event({
    hostname     : 'http://localhost',
    pagePath     : '/index',
    pageTitle    : 'Hello World',
    eventCategory: 'ga-event',
    eventAction  : 'click',
    eventLabel   : 'test event',
    eventValue   : 0,
    cd1          : 'Android', // e.g. System
    cd2          : 'English', // e.g. Language
    // you can add more custom dimensions below... 
});

/*
 * To solve: Uni-app使用axios在真机运行时会提示: adapter is not a function
 * 
 * You need to define your own axios adapter:

const adapter = (config, resolve, reject) => {
    uni.request({
        method: config.method.toUpperCase(),
        url: config.url,
        header: config.headers,
        data: config.data,
        dataType: config.dataType,
        responseType: config.responseType,
        sslVerify: config.sslVerify,
        success: function (response) {
            response = {
                data: response.data,
                status: response.statusCode,
                errMsg: response.errMsg,
                header: response.header,
                config: config
            };
            resolve(response);
        },
        fail: function (response) {
            reject(response);
        }
    })
};
# Replace default axios adapter with your own handler
ga.setAxiosAdapter(adapter);
