You might have heard issues about Gatsby a couple of years in the past, and in the event you’re not keeping track of what we’re doing right now, it’s solely comprehensible so that you can assume nothing has modified.
Naturally, given Gatsby operates within the JavaScript area, issues haven’t solely modified in the previous few years, however they’ve additionally doubtless modified in the previous few weeks. Because of this I’ve written this text explaining what Gatsby can do right now, and the way I used a few of our new options when upgrading my private web site: paulie.dev from Gatsby 2 to Gatsby 4.
Let’s dive in!
Server-Facet Rendering (SSR)
Within the fall of 2021, Gatsby launched Gatsby 4 with SSR help. I’ve used this on paulie.dev/dashboard. There are three options on my dashboard which might be ideally suited to SSR
Now let’s dive into every of those and the way Gatsby 4 enabled me to construct them simply!
All Reactions
The response information is requested from a Fauna Database, and displayed in an interactive Accordion part. The reactions are first grouped by sort (e.g. Comfortable, Cool, Tongue, and so forth) after which listed by slug (URL), and a rely can also be displayed for every of the grouped properties.
Guests By Nation And Guests By Location
The Guests By Nation information is requested from the brand new Google Analytics Knowledge API (GA4) and listed so as by the quantity of visits per nation. Guests By Location information is requested from the soon-to-be deprecated Google Analytics Core Reporting API (UA), and every location is plotted round a 3D globe that I created utilizing three.js / @react-three/fiber. It’s made interactive utilizing Orbit Controls from @react-three/drei. You may be questioning why I didn’t plot the GA4 information across the globe, too. The lat/lengthy required to plot the factors isn’t a part of the brand new GA4 API. See for your self within the GA4 Dimensions & Metrics Explorer (Constructed with Gatsby)
Right here’s an challenge on the ga-dev-tools GitHub Repo… fingers crossed it’ll get seemed into sooner or later. 🤞
The information displayed in these two options is updated as of the final time the web page loaded. The Guests By Nation information may also be displayed if JavaScript is disabled within the browser. The Interactive globe, sadly, won’t as a result of three.js wants JavaScript.
SSR/CSR Hybrid
SSR is an efficient possibility for information that adjustments comparatively shortly, however when utilizing SSR, the info will solely be “contemporary” when a consumer first visits the web page. If information had been to vary after the web page has loaded, customers would want to refresh the web page to see the most recent updates. That is the place a hybrid SSR with CSR (Consumer-side request) will help.
Newest Response
The Newest Response Characteristic makes use of this hybrid SSR/CSR method. If Javascript is disabled within the browser, the Newest Response is rendered utilizing SSR. Nevertheless, if JavaScript is enabled, I ballot the Fauna database utilizing a Gatsby Serverless Operate each 60 seconds and retrieve the most recent response. This implies the Newest Response isn’t greater than 60 seconds out-of-date and can refresh with out customers needing to reload the web page.
SSR/SSG Hybrid
Once more, while SSR is an efficient possibility, is it at all times wanted? A number of the information adjustments that happen on my web site occur due to one thing I modify. E.g I write a brand new put up, commit the adjustments and set off a construct. On this occasion, I’ve opted for a hybrid SSR with SSG (Static Website Era) method. The web page continues to be Server-side rendered however the charts are statically generated. (Sure, a web page may be each SSR and SSG.)
Knowledge Charts
I’ve used this hybrid method and created 4 information visualizations to assist me higher perceive the frequency with which I write and the sort of content material I’m writing about, and who for. Every of those charts is populated by information from round my web site that has been extracted from the frontmatter in my .mdx information after which queried from Gatsby’s information layer utilizing GraphQL.
These charts enable me to plot or rely the variety of posts or articles I’ve posted every month over the past 4 years, the quantity of posts or articles I’ve posted on every day of the week, the exterior publications I’ve written for (excluding Gatsby) and what number of occasions, after which lastly, a chart to point out the overall rely for every tag utilized in all the posts and articles.
As talked about, the dashboard of my web site is Server-side rendered, however all the above may be thought-about “static,” and usually talking, when people discuss with a static web site, they’re in all probability speaking about textual content and pictures on a web page.
The SSG information for the charts can’t actually exit of sync as a result of every time I write a brand new put up or article, I commit the .mdx file to my repository, which in flip kicks off a brand new construct in Gatsby Cloud.
This information can subsequently be thought-about updated as of the time the web page loaded and sure gained’t change in the course of the period of a web page view.
The best way I’ve created these charts makes use of the identical approach, however as a result of I like information, I selected to show it into one thing extra visually attention-grabbing. (enjoyable reality, none of those charts had been created utilizing a charting library).
They’re all hand-crafted utilizing good ol’ arithmetic, the SVG ingredient, and with assist from the next people and their nice tutorials — all will work with JavaScript disabled within the browser! 💅.

Line Chart | Kelsey Leftwich
Bar Chart | Kyle Shevlin
Radar Chart | Brian Foody
I desire this hand-crafted method as I discovered I’ve extra management over the ultimate output. After I’ve used charting libraries previously I at all times appear to be hacking excessive of one thing to get the specified look, and never all charting libraries will work if JavaScript is disabled within the browser.
Deferred Static Era (DSG)
With the discharge of Gatsby 4 (October 2011), Gatsby introduced DSG. This web page rendering technique is much like the tried and examined SSG method (the place pages are statically rendered on the server at construct time), however the important thing distinction is when.
Traditionally talking, all Gatsby pages had been SSG, and all pages must be constructed forward of time. While this typically ends in higher website positioning and a sooner consumer expertise than SSR, it will possibly have opposed results on construct occasions.
Builds are likely to fall into two principal classes, after which there are a couple of subcategories for every:
Native Improvement
Content material adjustments
Code adjustments
Modifications that have an effect on each web page (e.g. Header/Footer)
Modifications that have an effect on a single web page
Manufacturing Deployment.
Content material adjustments
Code adjustments
Modifications that have an effect on each web page (e.g. Header/Footer)
Modifications that have an effect on a single web page
When creating a Gatsby web site domestically, it’s not at all times advisable to construct each web page, luckily, whereas creating domestically you in all probability gained’t must construct all of the pages.
You need to use this “trick” in the event you like, it really works a deal with!: The right way to “repair” Gatsby’s sluggish native construct occasions.
For manufacturing, nonetheless, Gatsby might want to construct each web page and in case your content material is altering shortly or you might have a number of content material creators working in your web site, they’ll must see the constructed web page in a well timed style.
Content material creators sometimes gained’t be utilizing native .mdx information as I’ve on my web site to put in writing content material, so Gatsby/Gatsby Cloud has a lot of tremendous quick preview choices for widespread CMSs akin to Contentful, WordPress, Sanity, and plenty of extra!.
Particularly, within the case of manufacturing websites and content material adjustments, DSG may be configured to defer the static technology of any web page or sort of web page.
Briefly, through the use of DSG, Gatsby arms management of Static Website Era over to you, the developer. By selecting which pages to defer, you might have extra management over your construct occasions. In spite of everything, you recognize your web site higher than anybody, so that you’ll be capable to create a customized defer technique that works greatest to your wants.
How Does Gatsby’s DSG Work?
Let’s begin with the output. A web page created utilizing DSG is identical as a web page that has been created utilizing SSG. Which means: it’s a completely constructed HTML web page that’s been pre-built and cached on the server forward of time and is shipped to the browser when a consumer visits that web page.
It comprises all of the vital metadata that Google must index your web site and because the web page is pre-built, it’s tremendous quick and gives one of the best consumer expertise for finish customers.
When this web page is rendered, nonetheless, is the place DSG is available in.
If a web page is deferred utilizing DSG, then Gatsby gained’t pre-build it if you deploy your web site. As a substitute, the primary time a consumer visits that web page Gatsby will construct it on the fly, or just-in-time, after which ship it to the browser when it’s prepared. How is that this totally different from SSR, then?
How Is DSG Totally different From SSR?
The above will solely occur the primary time a web page is visited. When one consumer has visited a web page as soon as, the subsequent consumer shall be served an ahead-of-time pre-built SSG web page from the cache, and each customer after the primary will expertise the identical pace as if the web page had been rendered utilizing SSG.
With SSR, each customer will get the identical, generally sluggish expertise, as they’ve to attend for the Server to generate the web page earlier than it’s despatched to the browser. Usually, this leads improvement groups to optimize then cache headers, which is error-prone and oftentimes complicated. This results in ache for groups, and I desire to attenuate my very own!
When To Defer Utilizing DSG
I’ve seen some actually attention-grabbing defer methods from a lot of our clients. Some select to defer pages that aren’t visited that always and this technique is decided utilizing Google Analytics and web page view statistics. Others defer primarily based on the date a put up or article has been revealed; some defer primarily based on the recognition or inventory stage of a product. The choices you might have out there to you, are fairly frankly countless, every enterprise has its personal use case and Gatsby is versatile sufficient to accommodate any and all eventualities.
Right here’s a diff of the basic createPage; with DSG, you could possibly defer all however the newest 100 posts (supplied the posts have been sorted by date first, after all!)
posts.forEach((put up, index) => {
createPage({
path: put up.slug,
part: path.be a part of(__dirname, ./src/templates/posts.js),
context: {
id: put up.id,
},
// index is zero-based index
+ defer: index + 1 > 100,
})
})
…and for the curious, you may as well allow DSG in our different web page creation technique: File System Route API.
export async perform config() {
return ({ params }) => {
return {
defer: // your defer technique
};
};
}
This one small change sometimes ends in a fairly drastic discount in construct occasions. In fact, it relies upon upon the use case, however a few of our clients have diminished their construct occasions by over 50%, which implies that every construct offers them time again of their day to do extra attention-grabbing issues than anticipate a construct!
Serverless Capabilities
In the summertime of 2021 Gatsby launched Capabilities, I’ve used Capabilities for every of my; put up, article, demo, or stream pages to seize guests’ reactions.
Utilizing a set of SVG emojis, I invite customers to depart a response to my content material. When any of the emojis are clicked, I put up to a Serverless Operate from the consumer with the next payload.
await fetch(‘/api/add-reaction’, {
technique: ‘POST’,
physique: JSON.stringify({
title: title,
slug: slug,
response: response,
date: new Date()
})
});
The Serverless Operate, in flip, securely posts to a Fauna Database the place the info is saved and able to be retrieved and counted on the SSR web page as talked about above.
const faunadb = require(‘faunadb’);
export default async perform handler(req, res) {
const { title, slug, response, date } = JSON.parse(req.physique);
const q = faunadb.question;
const consumer = new faunadb.Consumer({ secret: course of.env.FAUNA_KEY });
strive {
await consumer.question(
q.Create(q.Assortment(`reactions_${course of.env.NODE_ENV}`), {
information: { title: title, slug: slug, response: response, date: date }
})
);
res.standing(200).json({ message: ‘Beautiful stuff, your response has been added!’ });
} catch (error) {
res.standing(500).json({ message: error.message });
}
}
Framework Enhancements
We’ve made enhancements to the core framework by including a couple of new APIs too! The brand new Script API, out there from 4.15.0, amongst different issues, comes with an off-main-thread script loading technique which can be utilized to dump third-party scripts (akin to Google Analytics) utilizing Builder.io ’s Partytown 🎉.
Offloading third-party scripts to a Internet Employee is a pleasant strategy to pace up web page masses. I wrote a little bit extra about this on my web site: The right way to use Gatsby’s Script API with Google Analytics.
We even have the brand new Head API. Traditionally talking, the beneficial means so as to add metadata to your HTML web page with Gatsby was to make use of react-helmet and gatsby-plugin-react-helmet.
Not anymore; from launch 4.19.0, this performance is included within the framework. I’ve written a put up detailing a standard migration sample in the event you’re to know extra. The right way to use Gatsby’s Head API with MDX.
Keep tuned for Slices API 🍕. There’s an open RFC right here on the Gatsby GitHub: RFC: Slices API.
Gatsby Cloud
The Gatsby framework is free and open supply and may be deployed on any variety of internet hosting suppliers. We have now created Gatsby Cloud as a handy strategy to streamline your developer expertise, with no further plugins or configuration required. Put merely: it’s one of the best place to construct, preview, and deploy your Gatsby web site.
While many previously have complained about Gatsby’s sluggish construct speeds, I typically ask, have you ever tried Gatsby Cloud?
Listed here are some construct pace benchmarks for my web site, which is presently ~110 pages. These are all .mdx apart from the dashboard, which, as talked about, is Server-side rendered.
Many of those pages include code block syntax highlighting, featured and embedded photos, embedded Tweets, Code Sandboxes, and YouTube movies. All of this provides to construct occasions, to not point out MDX taking a little bit longer to remodel than good ol’ Markdown (.md).
Notice: These outcomes are from the free tier of Gatsby Cloud (operating in Professional mode for the 14-day trial).
From backside to high, I’ll clarify the outcomes:
Triggered by Gatsby Cloud: 03.22
That is the primary time I deployed, and the positioning is constructed from a chilly cache.
Triggered by a guide Construct: 03.48
It is a guide construct, triggered by me, and is constructed from a chilly cache.
take a look at: content material change 1: 55s
This construct was triggered by a decide to GitHub after making a change to one among my posts and is constructed from a heat cache.
Chilly cache builds normally take longer as Gatsby Cloud has nothing to intelligently examine “what’s modified.” Nevertheless, when there’s a cache and the brains behind Gatsby Cloud do their factor, the construct speeds are nice! Personally, as a hobbyist developer, I’m high quality with ready 55 seconds for my web site to be constructed and deployed.
(Re) Introducing Gatsby, A Reactive Website Generator
If the above isn’t sufficient to show Gatsby is much more than merely a Static Website Generator, have a learn of Gatsby’s CTO’s current put up that describes how Gatsby takes benefit of a reactive method to regenerating a “static web site” when content material adjustments happen: (Re-) Introducing Gatsby, A Reactive Website Generator.
TLDR; When a Gatsby 4 web site is deployed to Netlify or Vercel, it will possibly solely behave as if it had been an SSG. When deployed to Gatsby Cloud, it will possibly behave as if it had been an RSG, lowering construct speeds in static web page re-generation by 100x!
On this video, Gatsby’s CTO Kyle Mathews demonstrates Gatsby Cloud reactively producing after which deploying a static web page in ~2 seconds and all from the push of a single button, our CMS previews have been in a position to do one thing related for some time however by no means earlier than has it been this quick!
Gatsby has developed fairly dramatically within the final two years. In case your expertise is with Gatsby 2, you might be stunned at how a lot sooner and extra versatile it has turn into with new web page rendering modes and capabilities like DSG and SSR, and we’ve acquired far more updates to come back!
I believe you’ll like what the hard-working people over right here have been doing, and in the event you do have any questions, please come say whats up on Twitter. 😊
