We finally get a way to add share buttons without forgetting a service or use. And respecting the privacy of our public. Go into all the world wide web and preach the method to all creation ! Well… who can use it, because, alas, that function is not everywhere.
Today, I talk about what lies behind the action button.
Here is my player, in its last development version. You can ⇓ jump ⇓ to ⇓ the ⇓ next ⇓ chapter ⇓
Yes, I know, I’m talking in French and this show is 5 years old, but I’m not sure to be a better radio host today. Yes, the interface is in French here, because my blog usually gets contents in French. It may be started in English.
The switchThe main interface of the player
This button (on the right of the main interface) will switch it to a share one. It is possible to hide this button and so denying access to the share interface via
hide="actions" attribute. It may be useful, by example when your website already have a share system.
Once the button clicked, you get some possible actions, on the whole width of the main interface of the web component :Seen in full width. If you don’t see exactly that, there is no problem : it’s the subject of my post.
This panel has some different actions as direct downloading the media file (according to which codec can be read by the browser, as we still get some old guns as Safari) and also share the sound via e-mail, twitter or facebook to relatives, sending them the canonical URL of the sound’s page. Due to limitations on those social networks, only e-mail gets a working media-fragment starting the play at the exact moment you were listening.
From left to right :
- a copy of the cover, going back to the main interface,
- share on Twitter (vanilla link),
- share on Facebook (vanilla link),
- share by e-mail (
- download the media (according to which codec can be read),
- cancel, going back to the main interface.
As my web component is in liquid design and mobile first, the interface is simplified on small width : cover and text labels are hidden.Yes I know. For any critics on icon’s design, please commit me better ones. I'm a coder, not Picasso.
Canonical URL means that if you want to share the radio show on cpu.pm front page, as i’m only showing the last broadcasted episode, its audio tag will be removed after next one is broadcasted, so there is a better choice : providing the page of the episode. And please, don’t look like you don’t use this useful tag. Yes, even if, as I do, you don’t code a website optimized for desktops, and a
.m one for mobiles, because, you know, it’s a loss of time.
If the canonical URL is not the one where is hosted the player, the
canonical="" attribute will do the job.
We already have browsers with a
share on social networks menu on mobile platforms. I’ve explained in a 2014 post in French about why I put again share buttons on my blog. It was 5 years ago, and, even if the general interface of the browsers moved, this over useful interface is still here.
Cool. Except that your browser will take the title of the page, a title encumbered with unmeaningful elements as separation glyphs, name of the site before title of the page, in extenso description of old-school SEO with a bunch of keywords names verbs persons marks important etc… Up to the user to clean it up and rephrase it.
Here enter the good fairies of the web standards :
The W3C introduced
navigator.share() aka WebShare, a function standardizing how to do it and allowing to suggest a bit longer description.
This function has numerous wins :
- being standard (in theory, I’ll explain later) ;
- not forgetting a service used by your reader (instead of the facebook/twitter classical duo) ;
- use a native control of the host OS, really more useful on smartphones ;
- deep sending you to the share function in the native app ;
- not tracking the users as do social networks with rich buttons (this is a shared win with classical HTML links) ;
- not tracking the users by the hosting website, guessing which sharing service they use ;
- not encumbering the small screen of a smartphone with gazillions of services.
Calling it is damn simple.
I’m really delighted having a so lean and perfectly thought process, instead to construct an instance builder with parameters set by another class serving a specific object and call it via an event dispatcher.

If you have a clean coded html page, your whole job is done. If it’s a piggy mess, you should start to not forget the
<meta... description tag.
By the way, you can share files with this standard’s level 2, and an API to test the share (
Pure genius !
Except :CanIUse.com support stats as taken when I wrote the original french post.
- This API is not available on desktop computers (except Safari Mac) ;
- It is also not available on Chrome Desktop, even in
responsivemode (by the way, not a real mobile emulation, and may induce you in error) ;
- This API is as today only on iOS and Chrome Android ;
- On iOS, each native app should carry its own sharing list, so we had a lot of missing ones due to the lack of a system-wide registry. We have it finally with, guess what ? Experimental support of
- It is still not possible of a online service accessed via a browser to be registered, as long Web Share Target API is nowhere implemented (and if it will be somewhere, we need to have it accepted by the user via a specific interface, to avoid spam attempts).
We have a very volatile scene of social networks, and the landing of decentralized hives, where inhabitants is supposed to easily migrate from an instance to another one. For 3 years Web Share is so under-esteemed and only usable on one platform is a real shame. I’m deeply convinced we have technical ability to build a WebExtension doing that job on desktop browsers.
I have some request to add, or being able to add, sharing option for a lambda website. Sure, I’d only put Facebook and Twitter, some people shamed me for forgetting Diaspora*, VKontakte, Mastodon, etc.social.random() in the action interface of my player. They are right.
Except the more you get in a limited place, smaller each button will be and all those services will be tight on the bench a wide as a smartphone. And, whatever we can do, there is no way to keep an exhaustive list of any available share services, even for specialized audience, for a real obvious point : New services appear each day.
Looking this image again, we note that a lot of those
social services that died during the last 5 years. And having so much begging puppies makes the whole page unreadable.
Well, I can not declare those missing services in the webcomponent code, and create an API permitting the web-developer to add some ?
Ahem. No. Wrong idea.
And I can bet that the web operator will forget some sharing services.
It also means giving to the integrator some parameters that may be harmful :
- describing a color, injecting it via the
- describing a monochromatic SVG logo, needed because of the color inversion on
- describing an URL canvas where to send for that sharing service, if a such URL exists.
Yes, I’m talking about you, social services with sharing systems that don’t support a simple link for that job. With the main motive to force your users using your mobile app full of tracking ads. You, nasty boys.
So what ?
I don't know what to tell.
Today, a feature detection replaces the facebook/twitter/e-mail buttons by a unique button, launching the
navigator.share() function. You can see it only on Chrome Android and Safari.

And later, yes, build a polyfill WebExtension may be a great idea (in a more generic and without jQuery way, compared to web-share-api by C. Zuber). As long as sharing services will collaborate without pollute it with
analytics and other ad-tracking.
For me, the best looking interface to add a share service in my browser is to re-use what already exists in Firefox to add a search engine. Because it's a lean interface, explicit one, standard-based and most of the work is already done there.
It’s up to you to build it, now. IMHO, this is not a over-difficult job to complete, and will be still a future-proof solution instead of any old AddThis script.
You can also support initiatives to add WebShare into :
Again, it was a long post talking about code, standard, implementations, but, for me, it worth it because this issue is not limited to my cpu-audio.js.
My next post in this series will be in French and talks about CSS, standards and implementations for some… strange colors.
May be it’s a frightening title, may be related to a horror story, so I have to say the killing sentence :
I’ll be back… soon !
