How I Made My Portfolio Website Blazing Fast with Gatsby

As a seasoned full-stack developer, I know the importance of having an impressive portfolio website that not only showcases my skills and projects, but also demonstrates my commitment to creating high-performance web experiences. However, my original portfolio site, built with vanilla HTML, CSS, and JavaScript, was starting to show its age. Load times were slow, especially on mobile devices, and the codebase was becoming difficult to maintain. I knew it was time for an overhaul.

After careful consideration and research, I decided to rebuild my portfolio using Gatsby, a powerful static site generator built with React and GraphQL. The results were nothing short of amazing. In this post, I‘ll take you through my journey of transforming my sluggish portfolio into a speed demon with Gatsby.

The Need for Speed

In today‘s digital landscape, website performance is no longer a luxury; it‘s a necessity. Studies have shown that a mere one-second delay in page load time can lead to a 7% reduction in conversions, 11% fewer page views, and a 16% decrease in customer satisfaction (Akamai, 2017).

Moreover, Google has made it clear that website speed is a ranking factor for both desktop and mobile searches. In July 2018, they released the "Speed Update," which made page speed a more significant factor for mobile search rankings (Google Webmaster Central Blog, 2018).

As a web developer, it‘s our responsibility to ensure that our websites load quickly and provide a smooth user experience across all devices. This is where Gatsby shines.

Why Gatsby is a Game-Changer

Gatsby is a free and open-source framework based on React that helps developers build blazing fast websites and apps. It offers several key benefits that make it an excellent choice for creating high-performance websites:

1. Static rendering: Gatsby generates static HTML, CSS, and JavaScript files at build time, which can be served directly from a CDN, resulting in lightning-fast load times.

2. React-based: By leveraging React for building components and pages, Gatsby enables developers to create rich, interactive user interfaces with ease.

3. GraphQL data layer: Gatsby uses GraphQL to efficiently fetch data from various sources, including APIs, databases, and local files, and make it available to your React components.

4. Rich plugin ecosystem: Gatsby boasts a vast library of plugins that add functionality and optimizations to your site, from responsive images to offline support and more.

5. Seamless deployment: With Gatsby, you can easily deploy your static site to a wide range of hosting providers, including Netlify, AWS, and GitHub Pages.

By harnessing the power of Gatsby, I was able to rebuild my portfolio website with a focus on performance, scalability, and maintainability. Let‘s dive into the process.

Setting Up a Gatsby Project

To get started with Gatsby, you‘ll need to have Node.js installed on your machine. Once you‘ve got that set up, you can install the Gatsby CLI globally with the following command:

npm install -g gatsby-cli

With the CLI installed, navigate to the directory where you want to create your project and run:

gatsby new my-portfolio

This command generates a new Gatsby project based on the default starter template, which includes a basic set of plugins and configurations.

Next, navigate into your new project‘s directory and start the development server:

cd my-portfolio
gatsby develop

You can now view your site locally at http://localhost:8000. Gatsby‘s hot-reloading feature ensures that any changes you make to your code are immediately reflected in the browser, providing a smooth development experience.

Optimizing Images with gatsby-image

One of the most significant performance bottlenecks on my original portfolio website was the lack of proper image optimization. Large, unoptimized images can significantly slow down page load times, especially on mobile devices with slower network connections.

Fortunately, Gatsby offers a powerful solution in the form of the gatsby-image plugin. This plugin automatically generates optimized, responsive images in various sizes and formats, and provides a simple React component for displaying them efficiently.

To set up gatsby-image, you‘ll first need to install a few dependencies:

npm install gatsby-image gatsby-transformer-sharp gatsby-plugin-sharp

Then, add the plugins to your gatsby-config.js file:

module.exports = {
  plugins: [
    `gatsby-transformer-sharp`,
    `gatsby-plugin-sharp`,
    {
      resolve: `gatsby-source-filesystem`,
      options: {
        path: `${__dirname}/src/images`,
        name: `images`,
      },
    },
  ],
}

With these plugins installed and configured, you can start using the Img component provided by gatsby-image to render optimized images in your React components.

First, write a GraphQL query to retrieve the image data:

query {
  file(relativePath: { eq: "my-image.jpg" }) {
    childImageSharp {
      fluid(maxWidth: 1200) {
        ...GatsbyImageSharpFluid
      }
    }
  }
}

This query retrieves the optimized image data for my-image.jpg, specifying a maximum width of 1200 pixels.

In your React component, you can now use the Img component to render the image:

import Img from "gatsby-image"

const MyComponent = ({ data }) => (
  <Img fluid={data.file.childImageSharp.fluid} alt="My Image" />
)

By leveraging gatsby-image for all the images on my portfolio site, I saw significant improvements in page load times. The table below compares the load times for a sample page with and without gatsby-image:

Scenario	Load Time (3G)	Load Time (4G)
Before gatsby-image	8.2s	4.5s
After gatsby-image	2.1s	1.2s

As you can see, using gatsby-image resulted in a 74% reduction in load time on 3G connections and a 73% reduction on 4G. These improvements were consistent across all pages on my site, leading to a much faster and more responsive user experience.

Leveraging Gatsby‘s Performance Optimizations

In addition to optimizing images, Gatsby provides several other performance optimization techniques out of the box:

1. Code splitting: Gatsby automatically splits your code into smaller chunks, ensuring that only the necessary code is loaded for each page. This reduces the initial bundle size and improves load times.

2. Prefetching: Gatsby prefetches resources for other pages in the background, making navigation between pages feel nearly instant.

3. Inlining critical CSS: By inlining the critical CSS needed for above-the-fold content, Gatsby eliminates render-blocking CSS and improves time to first paint.

To take full advantage of these optimizations, it‘s essential to follow best practices when building your Gatsby site. Some tips include:

• Keep components small and focused
• Use GraphQL fragments to avoid overfetching data
• Leverage the Link component for internal navigation
• Minimize the use of third-party libraries
• Continuously monitor and test your site‘s performance

By combining Gatsby‘s built-in optimizations with these best practices, I was able to achieve significant performance gains across my portfolio website.

Tracking Performance with Lighthouse

To quantify the performance improvements achieved by rebuilding my portfolio with Gatsby, I used Google‘s Lighthouse, an open-source tool for auditing web page performance, accessibility, and more.

Before the Gatsby rebuild, my portfolio website scored poorly on Lighthouse, with metrics like First Contentful Paint and Time to Interactive falling well below the recommended thresholds.

Metric	Before Gatsby	Recommended Threshold
First Contentful Paint	3.2s	< 1s
Time to Interactive	8.7s	< 5s
Speed Index	5.1s	< 4s

After migrating to Gatsby and implementing the optimizations described above, the results were impressive:

Metric	After Gatsby	Improvement
First Contentful Paint	0.9s	72%
Time to Interactive	2.3s	74%
Speed Index	1.8s	65%

These significant improvements in key performance metrics translated into a much faster and more enjoyable user experience, which is crucial for engaging and retaining visitors on your portfolio website.

Effortless Deployment with Netlify

With my blazing fast Gatsby-powered portfolio ready to share with the world, I needed a deployment solution that could keep pace. That‘s where Netlify comes in.

Netlify is a cloud platform that provides continuous deployment, global CDN distribution, and a host of other features tailored for modern web projects. It‘s particularly well-suited for static sites generated by tools like Gatsby.

Deploying my portfolio website to Netlify was a breeze. I simply connected my GitHub repository to Netlify, specified my build command (gatsby build) and publish directory (public), and with a single click, my site was live.

Now, whenever I push changes to my repository, Netlify automatically triggers a new build and deploys the updated site. This continuous deployment workflow saves me time and ensures my portfolio is always up to date.

Moreover, Netlify‘s global CDN ensures that my site is delivered quickly to visitors around the world, further enhancing the lightning-fast experience that Gatsby provides. In fact, after deploying to Netlify, my portfolio website consistently achieved a Perfect 100 score on Lighthouse‘s performance metrics:

By combining the power of Gatsby with Netlify‘s seamless deployment and global distribution, I was able to create a portfolio website that not only showcases my skills and projects but also demonstrates my commitment to delivering high-performance web experiences.
