Components

Reusable building blocks in software that handle specific functions and can be combined to build complete applications.

What are Components?

Components are self-contained pieces of code that handle a specific part of your application's UI or functionality.

Think of them like LEGO blocks. Each component does one thing well (a button, a form, a navigation bar) and can be reused across your app without rewriting code.

Most modern frameworks like React, Vue, and Svelte are built around components. You write a component once, then drop it anywhere you need it. Change it in one place, and it updates everywhere.

Components can be as simple as a single button or as complex as an entire checkout flow. The key is they're isolated, testable, and composable.

How Vibe Coders Use Components

1
Building a dashboard where the same card layout appears 20 times with different data
2
Creating a design system so your whole team uses the same buttons and forms
3
Dropping a pre-built authentication component into your app instead of building from scratch
4
Breaking down a complex checkout flow into smaller, testable pieces
