Assalomu Alaykum!.

Let's start by briefly understanding what the 📂Public folder is.

As the name suggests, public means ommaviy (public) in Uzbek. When users visit websites, all static assets that are directly presented to users on the front end are stored in the 📂Public folder. What are static assets? These are pre-saved resources such as images, videos, text, meta information, and other similar formats.

Importance:

Static Assets: Files stored in the Public folder (such as index.html, images, robots.txt, favicon.ico) speed up the loading time of the application and improve the user experience.

Global Access: Files in this folder can be accessed directly via a URL, making them easy to manage and use.

SEO and PWA: Files like robots.txt and manifest.json play a crucial role in optimizing your site for search engines and enabling Progressive Web App (PWA) features.

We've now briefly covered the Public folder!

Next, the general structure of the public folder in the React.js library is depicted in the image.

Let's take a detailed look at each file and its purpose:

1. index.html

Purpose: The index.html file is the main HTML template for a React.js application. This file is where the app is loaded, and the React application is rendered through a div element.

Contents: The file contains <head> and <body> tags, including title, meta information, link tags, and other HTML elements. The React application is typically loaded inside <div id="root"></div>.

2. robots.txt

Purpose: The robots.txt file sets rules for bots (e.g., search engine crawlers) that visit the website. Through this file, you can specify which pages should be included in search engines or which pages should be restricted from being crawled.

Contents: The file is in plain text format, listing URLs and rules, such as which URLs should be Disallowed from being indexed.

3. manifest.json

Purpose: The manifest.json file manages the PWA (Progressive Web App) features of the web application. This file defines how the app will appear and behave when installed on a device, including icons and color schemes.

Contents: The file is in JSON format, containing fields like name, short_name, icons, start_url, display, etc., which dictate how the app appears on mobile or desktop.

4. favicon.ico

Purpose: The favicon.ico is a small icon displayed on the browser tab of the website. This icon helps users identify the website within the browser.

Contents: The file is in ICO format, typically containing a small image (16x16 or 32x32 pixels).

5. Logo Variants

Purpose: Used to store the logos of the website or application in various sizes and formats. These logos are used within the app or during the PWA installation process.

Contents: Files may be in PNG, SVG, JPG, or ICO formats, and include logos of different sizes (e.g., 192x192, 512x512).

6. img

Purpose: The img folder is designed for images. All images used in the application, such as banners, background images, and other graphics, are stored here.

Contents: Image files in formats like JPG, PNG, GIF, or SVG.

7. data

Purpose: The data folder is used to store static data or JSON files. These files typically provide static content or initial data for the application.

Contents: Files in JSON or other static data formats.

The purpose of this folder is to ensure faster loading of the application and easier management of static assets. Each file or folder has its own role and plays an important part in the overall functioning of the application.
