# Getting Started with Gatsby - A Comprehensive Guide
Gatsby is a powerful static site generator that helps you build blazing-fast websites and apps. In this guide, we'll walk through the basics of setting up a Gatsby project and explore its key features.
## Why Choose Gatsby?
1. **Performance First**: Built with performance in mind, Gatsby pre-builds pages for faster loading times.
2. **React-Based**: Leverage the power of React components and ecosystem.
3. **GraphQL Integration**: Built-in GraphQL for efficient data handling.
4. **Rich Plugin Ecosystem**: Extensive collection of plugins for various functionalities.
## Setting Up Your First Gatsby Project
First, install the Gatsby CLI globally:
```bash
npm install -g gatsby-cli
```
Then create a new project:
```bash
gatsby new my-gatsby-site
cd my-gatsby-site
gatsby develop
```
## Key Concepts
### 1. Pages
In Gatsby, pages are React components located in the `src/pages` directory. Here's a simple example:
```jsx
import React from "react"
const HomePage = () => {
return (
<div>
<h1>Welcome to my site!</h1>
<p>This is my awesome Gatsby site.</p>
</div>
)
}
export default HomePage
```
### 2. GraphQL Queries
Gatsby uses GraphQL to manage data. Here's how to query page data:
```jsx
import { graphql } from "gatsby"
export const query = graphql`
query HomePageQuery {
site {
siteMetadata {
title
}
}
}
`
```
### 3. Images and Assets
Gatsby provides excellent image optimization out of the box:
```jsx
import { GatsbyImage, getImage } from "gatsby-plugin-image"
const MyImage = ({ data }) => {
const image = getImage(data.mdx.frontmatter.featuredImage)
return <GatsbyImage image={image} alt="Featured Image" />
}
```
## Best Practices
1. **Use Static Queries** for components that need data
2. **Optimize Images** using gatsby-plugin-image
3. **Implement SEO** using react-helmet
4. **Create Reusable Components** for consistent design
