What types of web applications exist?

There are several main types of web applications, distinguished by architecture, technologies used, and data loading methods:

Static web applications: Consist of a fixed set of HTML, CSS, and JavaScript files. The content does not change depending on the user or their actions.
Dynamic web applications: Content is generated on the server side in response to user requests. They use server-side languages (PHP, Python, Ruby, Node.js, etc.) and databases.
Single Page Applications (SPA): Load a single HTML page, and subsequent content changes are performed dynamically using JavaScript via APIs. Examples: Gmail, Trello.
Multi-Page Applications (MPA): Each user action or link click results in a full page reload from the server. Traditional approach.
Progressive Web Applications (PWA): Combine the capabilities of regular web applications and native mobile apps. They work offline, support push notifications, and can be installed on the device's home screen. Use Service Workers.
Serverless applications: Backend logic is executed using cloud services (e.g., AWS Lambda, Google Cloud Functions). Developers do not need to manage servers.
Microservice applications: Consist of a set of small, independently deployable services that communicate over the network.
