In this course, learn to build blazing fast apps and websites with React using Gatsby, a static PWA (Progressive Web App) generator. Over 50% of people will abandon a mobile site if it takes more than 3 seconds to load. Unless you’re willing to give up half of your potential customers, performance is no longer optional on the modern web. Fortunately, there are a lot of tools available to help you build screaming fast websites. Unfortunately, there’s a frighteningly large number of performance considerations, and many of them are easy to get wrong.
- Learn how to leverage free, open source tools including Gatsby, React, and GraphQL to build high-performance websites.
- Deliver an excellent experience to your users by providing only critical assets on load and prefetching assets for subsequent page loads.
- Implement performance best practices, such as the PRPL pattern, lazy loading assets, and more.
- Learn to build and deploy blazing fast websites in the fraction of time.
- Create websites quickly with performance baked in.
- Deploy your sites for free in minutes with Netlify.
We recommend getting the code running on your computer to build your confidence working with Gatsby. If you get stuck, use the Course Errata below to debug, or refer to the the step branches to see what is different between your code and the reference code.
You can jump into the CodeSandbox for each branch without having to get the code running on your computer. Keep in mind, that if you want to modify the code, you'll need to create a CodeSandbox free account to fork a new sandbox and save it to your CodeSandbox account.

Video: Rendering Components in MDX video at 1 minute, 32 seconds where Jason installs the Gatsby MDX plugin.
Fixed code: See this commit to migrate to gatsby-plugin-mdx
npm install gatsby-plugin-mdx instead of gatsby-mdx

resolve: 'gatsby-plugin-mdx',
options: {
defaultLayouts: {
default: require.resolve('./src/components/layout.js'),
},

Video: Getting Post by Slug at 4 minutes, 55 seconds where Jason gets the post body.
in post.js the query should be
export const query = graphql`
query($slug: String!) {
mdx(frontmatter: { slug: { eq: $slug } }) {
frontmatter {
title
author
}
body
}
}
`Instead of
export const query = graphql`
query($slug: String!) {
mdx(frontmatter: { slug: { eq: $slug } }) {
frontmatter {
title
author
}
code {
body
}
}
