🚀 PostIt – A Social Image Sharing App Built with React, Sanity, and Google OAuth

I recently built PostIt, a full-stack web application designed to make image sharing fun, interactive, and secure. It’s live at postit.berlinbruno.dev and open-source on GitHub.

🎯 What is PostIt?

PostIt is a modern image-sharing platform where users can:

• 📷 Share and explore creative images
• 🔐 Log in securely with Google
• 💬 Comment and engage with the community
• ⬇️ Download high-res images
• 🧠 Manage content with Sanity CMS

🔑 Login with Google OAuth

🏠 Home Feed

Scroll through a beautiful grid of community-uploaded images.

📤 Upload New Post

Upload an image, add tags, and publish in seconds.

🗣️ Comments Section

Interact directly with other users on image posts.

🔧 Tech Stack

• React.js ➝ Frontend framework for building interactive UIs
• Sanity CMS ➝ Headless CMS for managing content and images
• Google OAuth ➝ Secure authentication with Google login
• Tailwind CSS ➝ Utility-first CSS framework for rapid styling

🔐 Authentication via Google

PostIt uses Google OAuth for fast, password-free authentication. It gives users a secure and familiar login flow using their Google accounts.

📦 Sanity CMS for Headless Content

All content—images, metadata, user info, and comments—are stored and managed using Sanity. Its real-time editing and GROQ querying make it ideal for a performant and scalable content backend.

✨ Key Features

• ✅ Google Auth: Fast, secure sign-in
• 📤 Image Sharing: Upload, preview, and store content
• 💬 Commenting System: Threaded discussions on every post
• 🧠 Sanity CMS Integration: Smooth headless backend management
• ⬇️ Downloads: Save images locally with one click
