Exploring Github's Public Events with PHP and Google BigQuery

This article explores GitHub's public events API and demonstrates how to analyze this data using Google BigQuery and a PHP application built with Laravel. Because GitHub's API limits access to only the last 300 events, the article leverages the GitHub Archive, a historical repository of GitHub events stored in Google BigQuery.

Key Concepts:

• GitHub Public Events: These are user interactions on public GitHub repositories (e.g., pushing code, creating repositories). The inherent limitation of accessing only the most recent 300 events necessitates using a historical archive.
• GitHub Archive & Google BigQuery: The GitHub Archive, originally created to overcome the API's limitations, now resides in Google BigQuery. BigQuery's scalability allows for efficient querying of massive datasets.
• Laravel & Homestead Improved: The article uses Laravel as the PHP framework and Homestead Improved for the virtual machine environment.
• Google Cloud PHP Library: This library facilitates interaction with Google BigQuery's API from within the PHP application.

Analyzing GitHub Data with BigQuery:

The article guides you through setting up a Laravel application to connect to Google BigQuery. This involves:

• Creating a service provider (BigQueryServiceProvider) to manage Google service bindings.
• Implementing middleware (GoogleLogin) to handle user authentication.
• Constructing BigQuery queries using the Google_Service_Bigquery class.

Example Queries:

The tutorial provides examples of BigQuery queries, including:

• Retrieving the top ten most-forked projects. The original query using githubarchive:github.timeline is shown to be outdated, and a revised query using the yearly dataset (githubarchive:year.2014) is presented.
• Adapting the query to filter repositories by programming language (e.g., PHP, JavaScript). This involves adding a WHERE clause to the SQL query based on user input from a form.

Conclusion and FAQs:

The article concludes by emphasizing the power of combining GitHub's public event data with Google BigQuery's analytical capabilities. A comprehensive FAQ section addresses common issues related to using PHP with Google BigQuery, including authentication, error handling, query optimization, and data manipulation (insert, update, delete). The FAQs provide practical advice for developers working with these technologies.
