What is plugins in website?

A plugin is a piece of software that adds a specific feature or function to a website.

They work with content management systems, custom apps, and storefronts to avoid rewriting core code.

How plugins work on a website

Plugins use hooks, APIs, and modules to connect with a website's core system. They listen for events and run code when needed. Many plugins include settings pages, templates, or scripts that load only where required. Below are the common steps in how a plugin integrates:

• Activate the plugin so it registers its hooks and settings.
• Configure options through the plugin's admin interface.
• The plugin runs on page load or on specific actions like form submit.

Understanding what is plugins in website helps you see why a plugin can add features fast. Most platforms sandbox plugins, but their power depends on how well they use the system's APIs.
