Introduction

Hello there, fellow developers and tech enthusiasts! Welcome to our exciting journey of creating an open-source, full-stack social media platform. This document will guide us through the design and implementation of our project, which aims to provide a unique, user-friendly, and feature-rich social media experience. Let's dive in and explore the world of possibilities we're about to create!

Project Overview

Our project is an open-source, self-hosted social media platform designed to support up to 2,500 users. It will be built using a combination of PostgreSQL, MongoDB, and SQLite3 for data storage, with Express and Node.js powering the backend, and React for the frontend. The platform will support mixed content posts, including text, images, videos, and music, with advanced features like markdown support and wiki-style pages.

Key Features:

• Self-hosted solution
• No reliance on third-party authentication or advertisements
• Support for mixed content posts
• Markdown and wiki syntax support
• Tagging system
• Long-lived 'pages' for persistent content
• Customizable feed curation

Infrastructure and Storage

Hosting Environment

3. SQLite3

   • Local storage for client-side caching and offline functionality
   • Temporary data storage for improved performance

4. Object Storage (e.g., MinIO)

   • Storage for large media files (images, videos, music)
   • Scalable and easily integrated with CDN
