Indie web building blocks
I was back in Nürnberg last week for the second border:none. Joschi tried an interesting format for this year’s event. The first day was a small conference-like gathering with an interesting mix of speakers, but the second day was much more collaborative, with people working together in “creator units”—part workshop, part round-table discussion.
I teamed up with Aaron to lead the session on all things indie web. It turned out to be a lot of fun. Throughout the day, we introduced the little building blocks, one by one. By the end of the day, it was amazing to see how much progress people made by taking this layered approach of small pieces, loosely stacked.
The first step is: do you have a domain name?
Okay, next step: are you linking from that domain to other profiles of you on the web? Twitter, Instagram, Github, Dribbble, whatever. If so, here’s the first bit of hands-on work: add
rel="me" to those links.
<a rel="me" href="https://twitter.com/adactio">Twitter</a> <a rel="me" href="https://github.com/adactio">Github</a> <a rel="me" href="https://www.flickr.com/people/adactio">Flickr</a>
If you don’t have any profiles on other sites, you can still mark up your telephone number or email address with
rel="me". You might want to do this in a
link element in the
head of your HTML.
<link rel="me" href="mailto:firstname.lastname@example.org" /> <link rel="me" href="sms:+447792069292" />
As soon as you’ve done that, you can make use of IndieAuth. This is a technique that demonstrates a recurring theme in indie web building blocks: take advantage of the strengths of existing third-party sites. In this case, IndieAuth piggybacks on top of the fact that many third-party sites have some kind of authentication mechanism, usually through OAuth. The fact that you’re “claiming” a profile on a third-party site using
rel="me"—and the third-party profile in turn links back to your site—means that we can use all the smart work that went into their authentication flow.
You can see IndieAuth in action by logging into the Indie Web Camp wiki. It’s pretty nifty.
If you’ve used
rel="me" to link to a profile on something like Twitter, Github, or Flickr, you can authenticate with their OAuth flow. If you’ve used
rel="me" for your email address or phone number, you can authenticate by email or SMS.
Next question: are you publishing stuff on your site? If so, mark it up using h-entry. This involves adding a few classes to your existing markup.
<article class="h-entry"> <div class="e-content"> <p>Having fun with @aaronpk, helping @border_none attendees mark up their sites with rel="me" links, h-entry classes, and webmention endpoints.</p> </div> <time class="dt-published" datetime="2014-10-18 08:42:37">8:42am</time> </article>
Now, the reason for doing this isn’t for some theoretical benefit from search engines, or browsers, but simply to make the content you’re publishing machine-parsable (which will come in handy in the next steps).
Aaron published a note on his website, inviting everyone to leave a comment. The trick is though, to leave a comment on Aaron’s site, you need to publish it on your own site.
Webmention is basically a reimplementation of pingback, but without any of the XML silliness; it’s just a POST request with two values—the URL of the origin post, and the URL of the response.
My site doesn’t automatically send webmentions to any links I reference in my posts—I should really fix that—but that’s okay; Aaron—like me—has a form under each of his posts where you can paste in the URL of your response.
This is where those h-entry classes come in. If your post is marked up with h-entry, then it can be parsed to figure out which bit of your post is the body, which bit is the author, and so on. If your response isn’t marked up as h-entry, Aaron just displays a link back to your post. But if it is marked up in h-entry, Aaron can show the whole post on his site.
Okay. By this point, we’ve already come really far, and all people had to do was edit their HTML to add some
rel attributes and
For true site-to-site communication, you’ll need to have a webmention endpoint. That’s a bit trickier to add to your own site; it requires some programming. Here’s my minimum viable webmention that I wrote in PHP. But there are plenty of existing implentations you can use, like this webmention plug-in for WordPress.
Once you have a webmention endpoint, you can point to it from the
head of your HTML using a
<link rel="mention" href="https://adactio.com/webmention" />
Now you can receive responses to your posts.
Here’s the really cool bit: if you sign up for Bridgy, you can start receiving responses from third-party sites like Twitter, Facebook, etc. Bridgy just needs to know who you are on those networks, looks at your website, and figures everything out from there. And it automatically turns the responses from those networks into h-entry. It feels like magic!
Here are responses from Twitter to my posts, as captured by Bridgy.
That was mostly what Aaron and I covered in our one-day introduction to the indie web. I think that’s pretty good going.
The next step would be implementing the idea of POSSE: Publish on your Own Site, Syndicate Elsewhere.
You could do this using something as simple as If This, Then That e.g. everytime something crops up in your RSS feed, post it to Twitter, or Facebook, or both. If you don’t have an RSS feed, don’t worry: because you’re already marking your HTML up in h-entry, it can be converted to RSS easily.
I’m doing my own POSSEing to Twitter, which I’ve written about already. Since then, I’ve also started publishing photos here, which I sometimes POSSE to Twitter, and always POSSE to Flickr. Here’s my code for posting to Flickr.
I’d really like to POSSE my photos to Instagram, but that’s impossible. Instagram is a data roach-motel. The API provides no method for posting photos. The only way to post a picture to Instagram is with the Instagram app.
My only option is to do the opposite of POSSEing, which is PESOS: Publish Elsewhere, and Syndicate to your Own Site. To do that, I need to have an endpoint on my own site that can receive posts.
Working side by side with Aaron at border:none inspired me to finally implement one more indie web building block I needed: micropub.
Having a micropub endpoint here on my own site means that I can publish from third-party sites …or even from native apps. The reason why I didn’t have one already was that I thought it would be really complicated to implement. But it turns out that, once again, the trick is to let other services do all the hard work.
First of all, I need to have something to manage authentication. Well, I already have that with IndieAuth. I got that for free just by adding
rel="me" to my links to other profiles. So now I can declare indieauth.com as my authorization endpoint in the
head of my HTML:
<link rel="authorization_endpoint" href="https://indieauth.com/auth" />
Now I need some way of creating and issuing authentation tokens. See what I mean about it sounding like hard work? Creating a token endpoint seems complicated.
But once again, someone else has done the hard work so I don’t have to. Tokens-as-a-service:
<link rel="token_endpoint" href="https://tokens.indieauth.com/token" />
The last piece of the puzzle is to point to my own micropub endpoint:
<link rel="micropub" href="https://adactio.com/micropub" />
That URL is where I will receive posts from third-party sites and apps (sent through a POST request with an access token in the header). It’s up to me to verify that the post is authenticated properly with a valid access token. Here’s the PHP code I’m using.
It wasn’t nearly as complicated as I thought it would be. By the time a post and a token hits the micropub endpoint, most of the hard work has already been done (authenticating, issuing a token, etc.). But there are still a few steps that I have to do:
- Make a GET request (I’m using cURL) back to the token endpoint I specified—sending the access token I’ve been sent in a header—verifying the token.
- Check that the “me” value that I get back corresponds to my identity, which is https://adactio.com
- Take the h-entry values that have been sent as POST variables and create a new post on my site.
Finally, there’s OwnYourGram, a service that monitors your Instagram account and posts to your micropub endpoint whenever there’s a new photo.
Indie Web Camp
Each one of these building blocks unlocks greater and greater power:
Each one of those building blocks you implement unlocks more and more powerful tools:
But its worth remembering that these are just implementation details. What really matters is that you’re publishing your stuff on your website. If you want to use different formats and protocols to do that, that’s absolutely fine. The whole point is that this is the independent web—you can do whatever you please on your own website.
Still, if you decide to start using these tools and technologies, you’ll get the benefit of all the other people who are working on this stuff. If you have the chance to attend an Indie Web Camp, you should definitely take it: I’m always amazed by how much is accomplished in one weekend.
Some people have started referring to the indie web movement. I understand where they’re coming from; it certainly looks like a “movement” from the outside, and if you attend an Indie Web Camp, there’s a great spirit of sharing. But my underlying motivations are entirely selfish. In the same way that I don’t really care about particular formats or protocols, I don’t really care about being part of any kind of “movement.” I care about my website.
As it happens, my selfish motivations align perfectly with the principles of an indie web.
Indie web building blocks
I just published a lengthy write-up of the indie web building blocks that aaronpk and myself were showing in Nuremberg last weekend: https://adactio.com/journal/7698
So @adactio just posted a fantastic round up of #indieweb building blocks - . “Go and do likewise”
Bridgy by Ryan Barrett is another fantastic-looking and new-to-me tool for spinning up your own piece of the indie web. I’m really excited for the possibilities presented by it and webmention.io, both of which I found via Jeremy Keith. His Indie web building blocks post is one more great primer on how all this works.
I have so much to do.
Les briques de construction #indieweb par @adactio (Tout comme jeremy, prêt à partager bien que mes motivations pour comprendre et implémenter ces briques soient purement égoïstes !)
Last week I had the chance to attend the border:none 2014 and listen to very interesting talks. I didn’t know anything about the IndieWeb so far but that changed during the second day with hands-on work on how to integrate the first aspects and ideas.
Basically, own your content, be better connected and in control. Don’t let the social networks become „silos“ by posting everything only there.
Do you want to know more? Jeremy wrote a nice introduction on his blog. Enjoy!
