# 🔍 JSON Diff Viewer — React + TypeScript + Vite
This project is a powerful and user-friendly **JSON Diff Viewer** built with **React**, **TypeScript**, and **Vite**. It allows users to easily compare two JSON objects side-by-side and view the differences in a clean, syntax-highlighted, color-coded format. The tool is especially useful for developers, testers, and data analysts who need to analyze structural or data changes between JSON payloads.
## 🚀 Features
- 🧠 **Smart JSON Comparison** — Detects and highlights additions, deletions, and changes.
- 🌈 **Color Coded Output** —
- 🟩 Added keys/values
- 🟥 Removed keys/values
- 🟨 Modified values
- 🌓 **Dark/Light Mode Toggle** — Seamlessly switch themes to reduce eye strain.
- 🧾 **Syntax Highlighting** — Powered by `react-syntax-highlighter`.
- 🧩 **Side-by-Side Diff Layout** — Enhanced visual clarity of changes.
- ♻️ **Live Updates** — Re-renders diff on input change in real-time.
- 💡 **No Tailwind or UI Libraries** — Styled using clean, custom CSS.
## 🌍 Deployment Ready
You can deploy this project across multiple platforms with CI/CD integration:
- **Vercel** — Connect your GitHub repo and deploy instantly with zero config.
- **Cloudflare Pages** — Edge-deployed for super-fast delivery.
- **GitHub Pages** — Great for hosting fallback or demo versions.

# React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react/README.md) uses [Babel](https://babeljs.io/) for Fast Refresh
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
## Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
```js
export default tseslint.config({
extends: [
// Remove ...tseslint.configs.recommended and replace with this
...tseslint.configs.recommendedTypeChecked,
// Alternatively, use this for stricter rules
...tseslint.configs.strictTypeChecked,
// Optionally, add this for stylistic rules
...tseslint.configs.stylisticTypeChecked,
],
languageOptions: {
// other options...
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
},
})
```
You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
```js
// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'
export default tseslint.config({
plugins: {
// Add the react-x and react-dom plugins
'react-x': reactX,
'react-dom': reactDom,
},
rules: {
// other rules...
// Enable its recommended typescript rules
...reactX.configs['recommended-typescript'].rules,
...reactDom.configs.recommended.rules,
},
})
```
