WordPress.com

Hey! Chris here, with a big thanks to WordPress, for not just their sponsorship here the last few months, but for being a great product for so many sites I’ve worked on over the years. I’ve been a web designer and developer for the better part of two decades, and it’s been a great career for me.

I’m all about learning. The more you know, the more you’re capable of doing and the more doors open for you, so to speak, for getting things done as a web worker. And yet it’s a dance. Just because you know how to do particular things doesn’t mean that you always should. Part of this job is knowing what you should do yourself and what you should outsource or rely on for a trustworthy service.

With that in mind, I think if you can build a site with WordPress.com, you should build your site on WordPress.com. Allow me to ellaborate.

Do I know how to build a functional contact form from absolute scratch? I do! I can design the form, I can build the form with HTML and style it with CSS, I can enhance the form with JavaScript, I can process the form with a backend language and send the data where I need it. It’s a tremendous amount of work, which is fine, because hey, that’s the job sometimes. But it’s rare that I actually do all of that work.

Instead of doing everything from scratch when I need a form on a site I’m building, I often choose a form building service that does most of this work for me and leaves me with just the job of designing the form and telling it where I want the data collected to go. Or I might build the form myself but use some sort of library for processing the data. Or I might use a form framework on the front end but handle the data processing myself. It depends on the project! I want to make sure whatever time I spend working on it is the most valuable it can be &mdash not doing something rote.

Part of the trick is understanding how to evaluate technology and choose things that serve your needs best. You’ll get that with experience. It’s also different for everyone. We all have different needs and different skills, so the technology choices you make will likely be different than what choices I make.

Here’s one choice that I found to be in many people’s best interest: if you don’t have to deal with hosting, security, and upgrading all the underlying software that powers a website…don’t! In other words, as I said, if you can use WordPress.com, do use WordPress.com.

This is an often-quoted fact, but it bears repeating: WordPress powers about a third of the Internet, which is a staggering feature. There are an awful lot of people that are happily running their sites on WordPress and that number wouldn’t be nearly so high if WordPress wasn’t flexible and very usable.

There are some sites that WordPress.com isn’t a good match for. Say you’re going to build the next big Fantasy Football app with real-time scores, charts and graphs on dashboards, and live chat rooms. That’s custom development work probably suited for different technology.

But say you want to have a personal portfolio site with a blog. Can WordPress.com do that? Heck yes, that’s bread and butter stuff. What if you want to sell products? Sure. What if you want to have a showcase for your photography? Absolutely. How about the homepage for a laundromat, restaurant, bakery, or coffeeshop? Check, check, check and check. A website for your conference? A place to publish a book chapter by chapter? A mini-site for your family? A road trip blog? Yes to all.

So, if you can build your site on WordPress.com, then I’m saying that you should because what you’re doing is saving time, saving money, and most importantly, saving a heaping pile of technical debt. You don’t deal with hosting, your site will be fast without you ever having to think about it. You don’t deal with any software upgrades or weird incompatibilities. You just get a reliable system.

The longer I work in design and development, the more weight I put on just how valuable that reliability is and how dangerous technical debt is. I’ve seen too many sites fall off the face of the Earth because the people taking care of them couldn’t deal with the technical debt. Do yourself, your client and, heck, me a favor (seriously, I’ll sleep better) and build your site on WordPress.com.

A Basic WooCommerce Setup to Sell T-Shirts

WooCommerce is a powerful eCommerce solution for WordPress sites. If you’re like me, and like working with WordPress and have WordPress-powered sites already, WooCommerce is a no-brainer for helping you sell things online on those sites. But even if you don’t already have a WordPress site, WooCommerce is so good I think it would make sense to spin up a WordPress site so you could use it for your eCommerce solution.

Personally, I’ve used WooCommerce a number of times to sell things. Most recently, I’ve used it to sell T-Shirts (and hats) over on CodePen. We use WordPress already to power our blog, documentation, and podcast. Makes perfect sense to use WordPress for the store as well!

What I think is notable about our WooCommerce installation at CodePen is how painless it was, while doing everything we need it to do. I’d say it was a half-day job with maybe a half-day of maintenance every few months, partially based on us wanting to change something.

The first step is installing the plugin, and immediately you get a Products post type you can use to add new products. We’re selling a T-Shirt, so that looks like this:

Note the variations in use for size. We even track inventory at the size level so our T-Shirt printing company knows when to re-print different sizes.

What is somewhat astounding about WooCommerce is that you might need to do very little else. You could set a price, flip on the basic PayPal integration and enter your email, publish the product, and start taking orders.

Or, you could start customizing things and do as much or as little as you want:

  • You could add as many different payment processors as you like. We like using Stripe for credit card processing at CodePen, but also offer PayPal.
  • You could customize the template of every different page involved, or just use the defaults. At CodePen we have very lightly customized templates for the store homepage and product page.
  • You could get very detailed with calculating shipping costs, or use flat rates. We use a flat rate shipping cost at CodePen almost as marketing: same shipping cost anywhere in the world!
  • You could get into integrations, like connecting it with your MailChimp account for further email marketing or Slack account to notify your team of sales.

If you can dream it, you can do it with WooCommerce.

At CodePen, we work with a company called RealThread that actually prints and ships the T-Shirts.

They work great with WooCommerce of course, and the way we set that up is that we use the ShipStation integration and blast the orders into their account there and they handle all the fulfillment from there. There are all sorts of shipping method plugins though for anything you can think of.

Within WooCommerce, we have a dashboard of all the orders, their status, and even tracking information should we need to look something up.

So essentially:

  1. We use WooCommerce
  2. We use the Stripe plugin to take our credit card payments that way
  3. We use the PayPal plugin to take PayPal payments over Braintree
  4. We use the ShipStation plugin to send orders to that system for our fulfillment company to handle

It was quite easy to set up and works great, and it’s comforting to know that we could do tons more with it if we needed to and support is there to help.

Learning Gutenberg: Building Our Custom Card Block

We’ve got some base knowledge, we’ve played with some React and now we’ve got our project tools set up. Let’s dive into building our custom block.

Article Series:

  2. What is Gutenberg, Anyway?
  3. A Primer with create-guten-block
  4. Modern JavaScript Syntax
  5. React 101
  6. Setting up a Custom webpack
  7. A Custom “Card” Block (This Post)

What we’re building

We’re going to build a custom card block that features an image, a title and a summary. It’s a really common design pattern in the web and it also let’s us look at some core Gutenberg components, along with core WordPress elements, such as the Media Library. We’ll also play with some display logic with JSX for the front-end markup.

Our glorious custom card block!

Our glorious custom card block!

We’re going to focus solely on the the previous section. In your active plugin folder, this is located at blocks/src/block/block.js.

If you are working from the file structure created with create-guten-block, you might want to start by deleting everything in block.js and writing your code from scratch along with the tutorial.

Right at the top of this file, add the following:

const { registerBlockType, RichText, MediaUpload, PlainText } = wp.blocks;
const { Button } = wp.components;

We covered destructuring assignments in Part 2, create-guten-block? In case you need reminding, check it out here. The first six of those were relatively straightforward and involved replacing strings or bit of HTML. The seventh item, “Make the paragraph text editable,” is much more complicated to implement and was intended to get you thinking a bit. The time has come though, and we will indeed make some text editable in Gutenberg!

You may also recognize this registerBlockType function from the PHP register_block_type function we used in the last article. While that function registers a block from the server-side of WordPress, this one registers our block into the React ecosystem on the client side. Both are necessary to have a block that uses React, and their registered names, card-block/main must match.

Add the following code, but make sure you put a comma after 'common', so it looks like this: 'common',.

Here’s the code:

attributes: { title: { source: 'text', selector: '.card__title' }, body: { type: 'array', source: 'children', selector: '.card__body' }, imageAlt: { attribute: 'alt', selector: '.card__image' }, imageUrl: { attribute: 'src', selector: '.card__image' }
}

Here, we are defining the editable attributes of our block and the DOM selector that they are assigned to. This attribute object works in a very similar way to the React state object. It even has a very similar updating method called setAttributes. We’ll get to that later though.

At this point, it’s worth a brief overview of state and attributes because they represent a whole new way of thinking for WordPress developers. I’ll take over for a moment to go over them.

About Attributes and State

It may look like a simple JavaScript object, but that chunk of attributes introduces a whole swath of new concepts to a WordPress theme developer’s brain, not least of which is state. The concept of state has a long history in computer science, and life in general, really. Almost everything has a state. What state is your coffee cup in now? Empty, almost empty? How about your clothing? Are your shoes dirty or new? How about your body? Are you tired or wide awake?

At a high level, state simply refers to the present condition of a thing. In computer science, that thing is a computer program, and that program can be much, much simpler than what we create here on the web. Take a vending machine, for instance. The vending machine has a state that updates each time you put in a coin. When the state of the machine reaches a predefined amount, say $1.25, the machine knows to allow you to make your snack choice.

In Gutenberg, attributes track the present condition of data in a block. Attributes are the closest parallel we can draw to custom fields in Gutenberg, but they exist only in the context of Gutenberg and JavaScript. Let’s take the attribute above for title, for example:

title: { source: 'text', selector: 'card__title'
},

When Gutenberg fires up, it says, “I need to find some text inside a selector called .card__title, and populate the value for title with whatever I find.”

Attributes in Gutenberg are not directly connected to the database like custom fields are connected to post_meta. The entries source and selector are instructions for Gutenberg to populate the state of each block. When we load up the editor, it follows these instructions and assigns a value to title based on the markup saved in the database between the HTML comments that indicate a block of this type. We don’t see the value of title in the attributes we register, but if I were to access props.attributes.title, I would get whatever text exists in .card__title.

We’ve set up some basics, so let’s dive in to our edit function. This is what’s called when the block is accessed from the Gutenberg editor in visual mode. The user will see the rich interface, rather than the HTML code that it generates. That’s what I’ll cover next.

Add our edit function

Let’s add some code in. Add the following after the closing } of the attributes object. Like before, make sure you add a trailing comma, so it looks like this },.

Add the following code after that:

edit({ attributes, className, setAttributes }) { return ( );
}

So, we’re using another destructuring assignment to selectively pick our passed parameters to the edit function. The two most important are attributes and setAttributes. The attributes parameter is the same as the attributes block, but it’s the current, reactive state. This means if the setAttributes function updates one of the attributes values, it will automatically update anywhere that references it, which is similar to our React component from Part 3.

There’s a big ol’ return in this function. Can you guess what’s going in it? Yup! We’re going to stick some JSX in there. Add the following within the return parentheses:

<div className="container"> <MediaUpload onSelect={ media => { setAttributes({ imageAlt: media.alt, imageUrl: media.url }); } } type="image" value={ attributes.imageID } render={ ({ open }) => getImageButton(open) } /> <PlainText onChange={ content => setAttributes({ title: content }) } value={ attributes.title } placeholder="Your card title" className="heading" /> <RichText onChange={ content => setAttributes({ body: content }) } value={ attributes.body } multiline="p" placeholder="Your card text" />
</div>

OK, there’s a lot going on in here, but it’s all stuff we’ve covered in previous parts of this series. What we’ve got here is a container with three existing Gutenberg components. For each, we are setting the relevant attribute as its value, a relevant placeholder and an onChange/onSelect handler. We’re also passing a custom renderer to the <MediaUpload />, which we’ll cover shortly.

Each onChange handler is a handy little expression that passes the new content that triggered the onChange into the setAttributes function, where we set which attributes object to update. This update then cascades into any reference of that attribute, where the content will update like magic. The <MediaUpload /> element features an onSelect event which is fired when the user selects or uploads an item to the media library.

Speaking of the <MediaUpload /> element, you’ll notice there’s a custom render attribute, which references a getImageButton function. Let’s write that next. Above the return in the edit function add the following:

const getImageButton = (openEvent) => { if(attributes.imageUrl) { return ( <img src={ attributes.imageUrl } onClick={ openEvent } className="image" /> ); } else { return ( <div className="button-container"> <Button onClick={ openEvent } className="button button-large" > Pick an image </Button> </div> ); }
};

What this function does is detect if there’s an imageUrl in the attributes object. If there is, it’ll render that <img /> tag and let a user click it to select another. If there’s no image, it’ll render a WordPress <Button /> which prompts the user to pick an image. This calls the same openEvent that was passed into the function.

To keep things simple in this tutorial, we’ve bound a click to the <img /> element. You should consider building something fancy that leverages a <button /> for your production-ready blocks, for better accessibility support.

Right, that’s our edit function done. Not much code there, considering what it actually does, which is great!

Add our save function

We’ve got our Gutenberg editor-end of the block written now, which is the hard part. Now all we’ve got to do is tell Gutenberg what we want the block to do with the content. With the same reactive data from attributes, we can render out our front-end markup in real-time, too. That means when someone switches into HTML editing mode on the block, it’ll be up to date. If you edit it in HTML editing mode, the visual mode will also be kept up to date. Super useful.

Let’s dig in then. After our edit function, add a comma, so it looks like }, and then add the following on a new line:

save({ attributes }) { const cardImage = (src, alt) => { if(!src) return null; if(alt) { return ( <img className="card__image" src={ src } alt={ alt } /> ); } // No alt set, so let's hide it from screen readers return ( <img className="card__image" src={ src } alt="" aria-hidden="true" /> ); }; return ( <div className="card"> { cardImage(attributes.imageUrl, attributes.imageAlt) } <div className="card__content"> <h3 className="card__title">{ attributes.title }</h3> <div className="card__body"> { attributes.body } </div> </div> </div> );
}

Looks pretty similar to the edit function, right? Let’s step through it.

We start of by using a destructuring assignment to pull out the attributes from the passed paramaters, just like the previous edit function.

Then we have another image helper function that firstly detects if there’s an image and returns null if there’s not one. Remember: we return null in JSX if we want it to render nothing. The next thing this helper does is render a slightly varied <img /> tag if there’s alt text or not. For the latter, it hides it from a screen-reader by adding aria-hidden="true" and setting a blank alt attribute.

Lastly, our return spits out a nice .card block with clean, BEM-driven markup that will load on the front-end of our theme.

And that is that for our save function. We’re so close to having a completed block. Just one more step to go!

Add some style

OK, we’ve got this little bit to do and we’re done. The observant amongst you may have noticed some references to className dotted about. These are referencing our editor.scss rules, so let’s add them.

Open up editor.scss, which lives in the same directory as block.js. Add the following:

@import '../common'; .gutenberg { .container { border: 1px solid $gray; padding: 1rem; } .button-container { text-align: center; padding: 22% 0; background: $off-white; border: 1px solid $gray; border-radius: 2px; margin: 0 0 1.2rem 0; } .heading { font-size: 1.5rem; font-weight: 600; } .image { height: 15.7rem; width: 100%; object-fit: cover; }
}

This is some loose CSS to give our block some card-like style. Notice it’s all nested within a .gutenberg class? This is to battle the specificity of some core styles. Within the editor, there is a <div class="gutenberg" wrapped around the block area of the post editor screen, so we can make sure to only affect those elements with this nesting. You’ll probably also notice that we’re importing another Sass file, so let’s fill that one.

Open common.scss which lives in the src directory, which is the parent of the current block directory that we’re in.

/* * Common SCSS can contain your common variables, helpers and mixins * that are shared between all of your blocks. */ // Colors
$gray: #cccccc;
$off-white: #f1f1f1;

Anyway, guess what? We’ve only gone and built out a custom card block!! Let’s give it a test-drive.

First, check your block is all-good. This is what the complete block.js file should look like:

const { registerBlockType, RichText, MediaUpload, PlainText } = wp.blocks;
const { Button } = wp.components; // Import our CSS files
import './style.scss';
import './editor.scss'; registerBlockType('card-block/main', { title: 'Card', icon: 'heart', category: 'common', attributes: { title: { source: 'text', selector: '.card__title' }, body: { type: 'array', source: 'children', selector: '.card__body' }, imageAlt: { attribute: 'alt', selector: '.card__image' }, imageUrl: { attribute: 'src', selector: '.card__image' } }, edit({ attributes, className, setAttributes }) { const getImageButton = (openEvent) => { if(attributes.imageUrl) { return ( <img src={ attributes.imageUrl } onClick={ openEvent } className="image" /> ); } else { return ( <div className="button-container"> <Button onClick={ openEvent } className="button button-large" > Pick an image </Button> </div> ); } }; return ( <div className="container"> <MediaUpload onSelect={ media => { setAttributes({ imageAlt: media.alt, imageUrl: media.url }); } } type="image" value={ attributes.imageID } render={ ({ open }) => getImageButton(open) } /> <PlainText onChange={ content => setAttributes({ title: content }) } value={ attributes.title } placeholder="Your card title" className="heading" /> <RichText onChange={ content => setAttributes({ body: content }) } value={ attributes.body } multiline="p" placeholder="Your card text" formattingControls={ ['bold', 'italic', 'underline'] } isSelected={ attributes.isSelected } /> </div> ); }, save({ attributes }) { const cardImage = (src, alt) => { if(!src) return null; if(alt) { return ( <img className="card__image" src={ src } alt={ alt } /> ); } // No alt set, so let's hide it from screen readers return ( <img className="card__image" src={ src } alt="" aria-hidden="true" /> ); }; return ( <div className="card"> { cardImage(attributes.imageUrl, attributes.imageAlt) } <div className="card__content"> <h3 className="card__title">{ attributes.title }</h3> <div className="card__body"> { attributes.body } </div> </div> </div> ); }
});

If you’re happy, let’s fire up webpack. While in your current plugin directory in terminal, run this:

npx webpack --watch

This is slightly different to the previous part in the series because we’ve added the --watch argument. This basically keeps an eye on your js files and re-runs webpack if they change.

Fire up the editor!

Let’s fire up the Gutenberg editor by loading up a post in the WordPress back end. In the Gutenberg editor, click the little plus icon and look in the “blocks” tab and there it is: our awesome new card block!

Go ahead and give it a test drive and add some content in there. Feels good right?

Here’s a quick video of what you should be seeing right now, with your fancy new card block:

And with that, you’re done 🎉

Here’s a thing you might be thinking: Aren’t blocks kind of a replacement for custom fields? Can’t I now create my own content structure directly within WordPress instead of using a plugin like Advanced Custom Fields? Not quite…

Blocks vs. Custom Fields

While Gutenberg does afford us the ability to customize the structure of data entry from the user’s experience, on the back-end it’s no different than the current WYSIWYG editor. Data saved from a block is part of the post_content column in the wp_posts database table—it’s not stored separately in wp_postmeta like custom fields. This means that, at present, we cannot access the data from our card block from another post in the same way we could if we had created custom fields for title, image and content with a standard Advanced Custom Fields setup.

That said, I could see some really interesting plugins surfacing that provide a way to port data from a block to other parts of a website. With the WordPress REST API, the possibilities are just about limitless! In our screencast, Andy and I took a stab at incorporating an API request into our card block and, although things didn’t turn out exactly as planned, the tools are already in place and you can get a taste of what could be possible with Gutenberg in the future. Time will tell!

Wrapping up and next steps

What a journey we’ve been on together! Let’s list out what you’ve learned in this series:

  • You’ve learned some core, modern JavaScript by getting to grips with ES6
  • You’ve learned the basics of JSX
  • You took that new knowledge and built out a React component from scratch
  • You then learned how webpack works and wrote a scalable config file for Gutenberg block development
  • Finally, you built custom Gutenberg card block from scratch

So, where can you go from here? Now that you’ve got some solid base knowledge from this series, you could do some further learning. There’s already fantastic resources for that:

  • Writing Your First Block Type on WordPress.org (Andy: That’s how I learned how blocks work)
  • Gutenberg Courses by Zac Gordon and Joe Casabona
  • Creating a Custom Gutenberg Block by Pete Tasker
  • Anatomy of a Custom Block by Morgan Kay
  • One Thousand and One Ways to Extend Gutenberg Today by Riad Benguella
  • Gutenberg talks on WordPress.tv

Some interesting case studies:

  • Auditing Your WordPress Plugin for Gutenberg
  • Gutenberg on Humanmade.com
  • Modern Tribe’s “Going Gutenberg”

Keep an eye on these resources to stay up to date with the project:

  • Gutenberg News
  • Gutenberg Times

Experimental things happening with Gutenberg:

  • Gutenberg Custom Fields plugin
  • Atomic Blocks plugins and theme

Once Gutenberg becomes part of WordPress core in version 5.0 (release date TBD), you could also publish a useful custom block in the WordPress plugins directory. There’s definitely room for some handy components such as the card block that you’ve just built.

We hope you’ve enjoyed this series, because we’ve certainly enjoyed making it. We really hope this helps you get into Gutenberg and that you build some cool stuff. You should totally send us links of stuff you have built too!
