…about my attention. Thanks, Otis

Thor does the same…

image: Thor looks up from the windowsill to the camera with a very satisfied look. His blue eyes gaze hypnotically my way as his pink nose points upward, whiskers pridefully twitching.

He’s very satisfied with himself.

Who could resist them?

Northwestern Mutual

I am also a senior Design Systems engineer at Northwestern Mutual.

Design Systems are ALWAYS the hotness [image]: Person in inflatable dinosaur costume flips into a raft floating on a pond and claps with glee.

And I love Design Systems! it’s exciting work! Especially if you like…

…herding kittens. Always fun, with many moving parts. Part of Design System work includes trying out different software stacks and choosing the best tool for your system, like Gatsby.

Image: Gatsby and MDX logo

Speaking of Gatsby and MDX, they’re what I chose to build my Digital Garden site…

A digital what?

So… what is a digital garden?

What is a digital garden? [image]: Small potted plant next to a rake with caption, My blog is a digital garden, not a blog

this blog post by Joel Hooks, and this phrase makes sense to me: “What makes a garden is interesting. It’s personal. Things are organized and orderly, but with a touch of chaos around the edges.”

Image: Gatsby and MDX logo

● I latched on to the idea of creating a digital garden and using Gatsby and MDX as my stack for a few reasons…

● One because I tend to love trying…

image: ALL THE THINGS Hyperbole and a Half

All the things! All the latest software, but at the same time…

Perfection is the enemy of done

I struggle with making progress over seeking perfection, and if I’m not careful, lean towards making…

image: A Lexus with a big red bow juxtaposed next to a tiny floofy beige kitten with a red bow

● “Big Lexus bows” vs. “Tiny kitten bows”. Wow can I hyper-focus on the details, make that perfectly crafted piece of software before shipping. That’s heck on velocity, though.

● The digital garden format keeps me in the kitten bow mindset. This way, progress happens, and blog posts get written. New things get shipped.

There be weeds [image]: Two fluffy dandelion weeds in a green field

● Fast forward a few years and… a few talk listing and package updates later… I noticed that my Digital Garden got… weedy. And Gatsby had versioned up to 5.3, while my site was on 2.3

● I considering an upgrade and asked an industry colleague familiar with Gatsby how painful this upgrade would be. Of course I already knew the answer. 3 major versions. Ouch. But! After asking, and hearing the expected — yes it’ll be a pain — the advice leaned towards the obvious.

● “If it’s using JavaScript, it requires regular maintenance” (OK…) which turned into a suggestion to use Squarespace, since it didn’t require maintenance.

JavaScript is hard

And that kinda sounded like JavaScript’s hard… and maybe you’re out of your league…

JavaScript is hard …maybe you should build a Squarespace site?

“…maybe you should create a Squarespace site?”

image: Judy Hopps from Zootopia, shakes her head in disgust

Did you just say something was hard? Hello… spite driven development. By golly I would upgrade this app three versions up. Squarespace my butt.

10 hours later…

image: Judy Hopps from Zootopia, shakes her head in disgust

Still shaking my head about that Squarespace suggestion.

● Ten hours later, after a Netflix binge and upgrade session…I come up for air. I’ve fixed all the new GraphQL changes and was wrestling with the Gatsby image API, and now I’m questioning life choices…

● I was Just like combining jello with shellfish deciding to go all in was not a great decision.

"if you want a static site, why are you using a whole JavaScript framework to render it?"

I thought “I have a four-page static site. Why am I using a JavaScript framework to render four static pages in a blog, and…

Why use JSX to create HTML when you could just… use HTML?

● why am I using JSX to create HTML when I could just use HTML?”

● Granted, I work on Design Systems. I love creating component APIs, and love using React, so I’m the last person to say just throw it all out, but there are times where you need a four-page site without throwing all this JavaScript at it just to render something that’s small, lean, performant, and just doesn’t need to be a SPA, it needs to be a multi-page app.

I don't need a suite of combine machines. [image]: Large agricultural harvesting machines in a vast golden field

And the Gatsby of 2020 isn’t the same as it is today. That hot static site generator everyone wanted to use has evolved into this suite of industrial farming equipment.

I don’t need a combine machine when a hoe and rake will do for my needs.

Weed out the Complexity [image]: Gloved hand digging weeds out of a garden

● It was time to weed out the complexity, and choose a new framework

● One that will compile right down to HTML CSS and only serve the minimal amount of JavaScript if I need it.

So I looked around — and because there’s a bunch out there and… oh hai Astro… let’s take a look at you.

Why Astro?

● Why did I choose Astro?

● SolidJS Support

● I can try out different UI frameworks in Astro without going all-in

● I can bring in components from my other app and convert them one at a time without have to completely convert every component over at a time (some here are React, some are Solid, I’m using pragmas)

● Content-focused - fetch from a CMS or work locally with type-safe Markdown or MDX (which is the reason I want it)

● Content collections

● Type safety

Why Astro? [image] Astro documentation page

● Why did I choose Astro?

● Astro was designed for building content-rich websites. And I zeroed in on blogs, portfolios… I don’t need a logged-in dashboard, or complex native app interactions that NextJS would give me, so this seems like a safe bet.

MDX support

MDX support. I can add my MDX pages and move on.

PostCSS support

It supports PostCSS by default, so my current CSS setup will port over without much fuss.

Astro Islands

Astro Islands. These are interactive UI components on the page that render in isolation using partial/selective hydration

Convert some components or all components

So I can import my React components from my Gatsby project. I can choose to convert them to Astro components over time, or leave them as React components.

I can try out different UI frameworks in Astro

● I can try out different frameworks, like SolidJS, Vue without having to fully commit to a framework.

● And share state between them.

MPA Architecture

That’s pretty cool. Astro also uses MPA and server-side rendering vs a client-side Single-page app, so it’s performant.

Leaner configs

And the configs are much leaner. Check this out.

image: side-by-side comparison — gatsby-config.js 😀 astro.config.mjs 😀

Here the Gatsby’s config on the left versus Astros config on the right

image: side-by-side comparison — gatsby-config.js 😀 astro.config.mjs 😀

In the Astro config we have the site deploy url, markdown, integrations, image and build configs. All in a small list….

image: side-by-side comparison — gatsby-config.js 😀 astro.config.mjs 😀

And the Gatsby config has all these PostCSS imports… configs… site metadata…

image: side-by-side comparison — gatsby-config.js 😶 astro.config.mjs 😀

Plugins…

image: side-by-side comparison — gatsby-config.js 🤔 astro.config.mjs 😀

More plugins…

image: side-by-side comparison — gatsby-config.js 😐 astro.config.mjs 😀

MORE plugins…

image: side-by-side comparison — gatsby-config.js 😑 astro.config.mjs 😀

…to resolve…

image: side-by-side comparison — gatsby-config.js 😐 astro.config.mjs 😀

The config keeps going…

image: side-by-side comparison — gatsby-config.js 🫤 astro.config.mjs 😀

And… Going.

image: side-by-side comparison — gatsby-config.js 😬 astro.config.mjs 😀

And. Going.

image: side-by-side comparison — gatsby-config.js 😳 astro.config.mjs 😀

And. Going.

image: side-by-side comparison — gatsby-node.js 🫣 astro.config.mjs 😀

Here’s the Gatsby.node file for creating nodes because I didn’t want to have my blog posts under the source folder, so I could be really fancy and smart.

image: side-by-side comparison — gatsby-node.js 🙄 astro.config.mjs 😀

● Look and me go… and add unnecessary complexity!

● I had to create all these nodes and do GraphQL queries to make the absolute paths to create the posts. YAY,,,

image: side-by-side comparison — gatsby-browser.js 🙃 astro.config.mjs 😀

And a Gatsby browser file with this WrapRoot element so I could wrap styled components and pass them into MDX all at once for usage

Till the soil [image] Person digging with a spade into the soil

Once I ported my components over to an Astro project there were some differences

From React children to Astro slots

image: side-by-side comparison — layout.js Layout.astro

image: side-by-side comparison — layout.js Layout.astro

● Here the Gatsby layout page on the left versus the Astro layout page on the right.

● In the layout.js file, we’re importing React components and a CSS modules file

● In the Layout.astro file, the components are now astro components, and we’re using a CSS file and the Astro pageTitle prop.

image: side-by-side comparison — layout.js Layout.astro

In the Gatsby layout, we’d use classnames and the useExtraClasses utility for style concatenation

image: side-by-side comparison — layout.js Layout.astro

And in the Gatsby layout we use the children prop, where in the Astro layout we now use slot

Now that the layout is set, time to mulch some content.

From GraphQL to Content Collections

● First, ditch those GraphQL queries, and add in Astro’s Content Collections

● Content collections are the best way to manage and author content in any Astro project. Collections help to organize your documents, validate your frontmatter, and provide automatic TypeScript type-safety for all of your content.

image: GraphQL indexQuery

In Gatsby, I had this one query to grab images from a local folder. Literally 6 images.

image: GraphQL aboutQuery

This other one to grab images for my about page

image: GraphQL writeQuery

Queries for my write page, and a query for my MDX posts to parse all the data into readable format. That’s a lot for a small site.

image: Astro config.ts

● In comparison, Astro’s Content Collections Added in: astro@2.0.0 is much simpler.

● It allows you to organize your documents, validate frontmatter, and provide content schema type-safety.

Dynamically generating routes

Along with content collections, you can dynamically generate routes…

image: […slug].astro file

● By creating this […slug].astro file and use the getCollection function from astro:content and getStaticPaths functions to parse your data and pop it in your pages/posts folder.

● The getCollection function will grab your blog data, combined with the getStaticPaths function will map data for each of your posts.

● No more finagling post files. no more Gatsby CreatePage nonsense.

Type-safe MDX with Zod.

The other great thing about content collections is Type safety in your MDX with Zod

Zod… say what?

So what is Zod anyway?

Zod TypeScript-first schema validation with static type inference

The official definition is: TypeScript-first schema validation with static type inference. What that means is: Zod uses TS to create schemas to help you validate your data.

Plant new starters [image] hand planting starters in soil

Now that your content is defined and validated, time to plant new starters. We need to pull in some Images.

< Image />

Let’s use the new Images API

image:assets

New Image assets was released as stable in Astro 3.0 replaces the original @astrojs/image integration

image: <Image /> example file

This API the allows you to import any any image from the src/assets folder, and if when you pop it in the source and add the required alt attribute… yay a11y!…

image: <img /> example file

Astro generates this optimized images with the following attributes in the DOM for you

Stubborn Link Icon conversions

Oh boy… icons. This was fun… And time-consuming

From Gatsby-links to Astro links

First there was the whole Gatsby link conundrum

From ReactFontawesome to astro-iconify

image: side-by-side comparison — Link.jsx Link.astro

● I had a Link component, and wanted to leverage React Font Awesome for the a11y svg icon benefits, and got stuck for a week

● No matter what, Icon would break, couldn’t integrate the component

● Ended up refactoring to Link astro component and using astro-iconify and customizing icon svg imports, optimizing for a11y

What I’ve learned

To wrap up… here’s what I’ve learned from converting my site to Astro

Big Lexus bows vs. Tiny kitten bows

Naturally there was tension between Big Lexus bows and kitten bows as I migrated my site to Astro

Schemas are tricky. So are dynamic imports… with images.

CSS load order is no joke.

● _[…slug].css files load first because

● Markdown layout files load first because

● Base.css files load because

● We’re so clever with our main.css file yo and

● Now we’re overwriting something in our base styles

● Because we’re every-layout clever

https://every-layout.dev/layouts/stack/

● Also, astro files don’t like CSS modules

Clean up file cruft, or your Netlify deploys will fail

Netlify will pick up any stray YAML files during your build and if they don’t follow your schema… uh oh

ViewTransitions are Tricky …and buggy

Demo ViewTransition

Everything Everywhere at Once

Everything Everywhere at once… whew it was a challenge.

What components are still port over (yet)

Complex card

Custom MDX components

Custom MDX components… in particular…

custom CodeBlock with react-live/ DisplayBox

react-live doesn’t play well with custom components… yet

Thank you Astro team @Bryceguy @Sarah @Elian @Sarah11918 @Erika @Tony-Sull @Kevin @Yan @Otterlord

I want to give a huge shout out to a few people of the Astro core team and community that worked with me through my site conversion. Thank you, you are amazing!
