+# [Vite Crash Course – Frontend Build Tool](https://www.youtube.com/watch?v=do62-z3z6FM&ab_channel=freeCodeCamp.org)
+
+## Key Notes
+
+- Vite means fast in French.
+- Founder of Vite (2019) is Evan, also founder of Vue.js (2014).
+- Improves the development and feedback cycle so that we can see changes immediately.
+- Provides the initial code required for web development.
+
+## Requirements and Initial Setup
+
+- Node, npm
+
+```bash
+npm create vite@latest
+npm install && npm run dev
+```
+
+The application runs at http://localhost:5173/
+
+## Understanding Folder Structure Created by Vite
+
+- `index.html` – Starting point of the project.
+- `src/` – Contains source code and assets.
+- `package.json` – Includes all dependencies and npm scripts.
+- `vite.config.js` – Vite configuration and list of plugins.
+

+
+## Experience Fast Development
+
+- Vite uses Hot Module Replacement (HMR).
+- Replaces only the part/component that got updated instead of updating the entire application.
+- Example: I created a component and placed it in `App.jsx` and it showed instantly.
+
+## Handling Static Assets with Vite
+
+- Vite will hash or optimize the size of images while building. Images should be present in the `src` folder and imported using a relative path.
+
+![Building images](screenshots/Build.png)
+
+- All images and files have a hash value at the end and reduced size inside the `dist` folder.
+- Files you do not want optimized should be kept in `public` or outside the `src` folder.
+- Example: `vite.svg` is placed outside of `src` and in the `dist` folder it does not have the hashed at the end.
+
+![Building images](screenshots/public_folder.png)
+
+## Use Environment Variables in Vite
+
+- Use a `.env` file and all variables should start with `VITE_`.
+
+## Build for Production
+
+- `"build": "vite build"` → `npm run build`
+  - Creates a `dist` folder with all required files (some compressed) for production.
+- `"preview": "vite preview"` → `npm run preview`
+  - Boots up a local static server from the `dist` folder and runs on port 4173.
+
+## How Flexible is Vite – Configuration and Options
+
+- `vite.config.js` contains all configurations.
+- You can add additional plugins to the Vite application. Example:
+  - Install QR code plugin: `npm install --save-dev vite-plugin-qrcode`
+  - Use it in `vite.config.js`.
+  - After running `npm run dev`, you will see the plugin in action.
+

+
+## Why Vite?
+
+- Based on esbuild, rollup.js, and Rolldown (Rust-based), making the application very fast in rendering content.

+# React + 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) uses [Babel](https://babeljs.io/) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the [TS template](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-react-ts) for information on how to integrate TypeScript and [`typescript-eslint`](https://typescript-eslint.io) in your project.
