Post-Analyzer

Post Viewer and Analyzer with Go

Introduction

The Post Viewer and Analyzer is a web-based application built with Go. It serves a web interface that allows users to fetch posts from the JSONPlaceholder API, save these posts to a file, and perform a character frequency analysis on the saved data. This application demonstrates the use of Go for server-side web development, including handling HTTP requests, processing JSON, and rendering HTML templates.

Features

• Fetch Data: Users can fetch posts from the external JSONPlaceholder API.
• Save Data: Automatically saves fetched posts into a local JSON file.
• Analyze Data: Performs a character frequency analysis on the contents of the saved JSON file.
• Web Interface: Simple and user-friendly web interface to interact with the application.

Technology Stack

• Go: All server-side logic is implemented in Go, utilizing its standard library for web server functionality, file I/O, and concurrency.
• HTML/CSS: Front-end layout and styling.
• JSONPlaceholder API: External REST API used for fetching sample post data.
