🚀 GitHub User Activity CLI (Professional)

A high-performance, professional-grade Command Line Interface (CLI) designed to retrieve and visualize public activity streams from any GitHub user. This tool is engineered for speed, efficiency, and readability, utilizing concurrent network requests and a local caching layer to provide a seamless developer experience.

Repository: https://github.com/CW-Ankit/github-user-activity.git

🌟 Key Features

⚡ High-Performance Architecture

• Concurrent Data Fetching: Instead of sequential requests, the tool utilizes Promise.all() to fetch user profiles and activity events simultaneously, reducing the total wait time by approximately 50%.
• Intelligent Caching Layer: Implements a 'Cache-Aside' pattern. API responses are persisted to the system's temporary directory with a configurable Time-To-Live (TTL), preventing redundant network calls and protecting against GitHub API rate limits.

🎨 Professional Visualization

• Structured Table Layout: Activity is presented in a strictly aligned columnar format, ensuring that repository names and event types remain visually consistent across the feed.
• Semantic Color Coding: Uses ANSI escape codes to categorize events (e.g., Green for Pushes, Magenta for Stars, Yellow for Issues), allowing users to scan activity at a glance.
• Dynamic Filtering: Ability to isolate specific event types (e.g., only viewing PushEvent) via command-line flags.

🛠 Developer Experience

• Dual-Command Access: Supports both the full command github-activity and the ultra-fast shorthand gha.
• Graceful Error Handling: Comprehensive try-catch blocks manage everything from 404 (User Not Found) to network timeouts and DNS failures.

🚀 Installation

Prerequisites

• Node.js: Version 18.0.0 or higher.
• npm: Version 8.0.0 or higher.

Setup

1. Clone the repository:

   git clone https://github.com/CW-Ankit/github-user-activity.git
   cd github-user-activity

2. Install dependencies:

   npm install

3. Link the package globally: This step registers the github-activity and gha commands in your system's binary path.

   npm link

📖 Usage Guide

Basic Command

Fetch all public activity for a specific user:

gha <username>
# OR
github-activity <username>

Filtering Activity

If you only want to see specific types of events (e.g., PushEvent, WatchEvent, IssuesEvent):

gha <username> --filter=PushEvent

Help Manual

To view all available options and examples:

gha --help

🛠 Technical Deep Dive

🧠 Architectural Flow

1. Argument Parsing: The cli.js module extracts inputs from process.argv.
2. Cache Validation: api.js generates a unique key based on the endpoint and username. It checks the os.tmpdir() for a matching .json file.
3. Network Execution: Upon a cache miss, node:https is used to perform a GET request. A custom User-Agent is sent to comply with GitHub's API requirements.
4. Data Normalization: The formatter.js module maps raw JSON event types to human-readable labels and applies padding for terminal alignment.

⏱ Caching Logic

The cache uses a Time-To-Live (TTL) mechanism. By default, data is considered fresh for 10 minutes. After this window, the tool automatically invalidates the local file and performs a fresh network fetch to ensure data accuracy.
