Introduction

A Single-Page Application is a web application that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from the server.

How SPAs Work

Initially, the browser loads a single HTML page along with CSS and JavaScript files. As users interact with the app, JavaScript intercepts their actions (like clicking links or submitting forms) and updates the content dynamically without requiring a full page reload. SPAs often use AJAX requests to fetch or send data to the server asynchronously, updating the UI based on the server’s response.

Drawbacks of SPAs

1. SEO Challenges: Since the content is loaded dynamically, search engines might face difficulty indexing the site’s content which can potentially affect the site’s visibility.

2. Initial Load Time: Loading the entire application framework upfront can lead to longer initial load times.
