Develop GitHub Activity Metrics Script

[Sddilora]

Description:

Task a team member with developing a script that simulates accessing GitHub data as if it were their own account (using their own GitHub credentials for testing purposes). This script should retrieve daily and weekly metrics such as commits, pull requests, reviews, open issues, and closed issues, along with the estimated total time spent on these activities.

Objective:
Create a script capable of fetching GitHub activity metrics for a specified user, simulating access as if it were the user's own account.

Details:

• The script should utilize the GitHub API to retrieve activity data, including daily and weekly metrics for various activities.
• Metrics to be collected include:
  • Number of commits made daily and weekly.
  • Number of pull requests opened, reviewed, and merged daily and weekly.
  • Number of open and closed issues daily and weekly.
• Additionally, the script should calculate the estimated total time spent on these activities based on historical data or predefined estimates.
• Ensure that the script is well-documented, with clear instructions on how to use it and any dependencies required for execution.
• The script should be written in a programming language of choice, with preference given to languages commonly used within the team or easily maintainable by team members.

Tasks:

1. Research and familiarize yourself with the GitHub API and its endpoints for accessing user activity data.
2. Design and implement the script to fetch daily and weekly metrics for commits, pull requests, reviews, and issues.
3. Incorporate logic to calculate the estimated total time spent on each activity based on historical data or predefined estimates.
4. Test the script thoroughly to ensure accuracy and reliability of data retrieval and calculation.
5. Document the script's usage instructions, including any prerequisites or setup steps required.
6. Provide a brief demo or presentation to the team to showcase the functionality of the script and gather feedback for potential improvements.

Deliverables:

• Fully functional script capable of fetching GitHub activity metrics and calculating estimated total time spent on activities.
• Comprehensive documentation outlining the script's functionality, usage instructions, and any dependencies required.
• Demo or presentation to the team demonstrating the script's capabilities and gathering feedback for further refinement.

Feel free to further elaborate or provide additional requirements for this issue.

This code is a Go program that retrieves the weekly activity of a specific user using GitHub's REST API.

Firstly, the getUserActivity function is called with a given username and GitHub token. This function fetches the number of actions (commits, issues, and pull requests) performed by the user in the last week, along with their respective dates.

GitHub API is utilized to obtain this information through three different URLs:

commitURL: Retrieves the commits made by the user.
issueURL: Fetches the issues created by the user.
pullRequestURL: Retrieves the pull requests created by the user.
Each URL queries the user's activities within a specific date range, starting from one week prior to the execution of the code and ending at the time of execution.

GET requests are made to each URL to connect to the GitHub API and obtain responses. The responses are returned in JSON format, and these JSON data are processed to determine the counts of commits, issues, and pull requests.

Additionally, date information for each activity is also obtained. Separate GET requests are made for this purpose, and the returned JSON data are processed to retrieve the date of each activity.

Finally, the obtained data is printed in the main function. The total counts of commits, issues, and pull requests, along with their respective dates, are printed to the console.

The purpose of this code is to report the weekly activities and their dates for a specific GitHub user.
