I’ve already had some thoughtful responses to yesterday’s post about trust. I wrapped up my thoughts with a request:
I would love it if someone could explain why they avoid native browser features but use third-party code.
Very true! jQuery is the canonical example of a library smoothing over the bumpy landscape of browser compatibilities. But jQuery is also the canonical example of a library we no longer need because the browsers have caught up …and those browsers support standards directly influenced by jQuery. That’s a library success story!
Charles Harries takes on my question in his post Libraries over browser features:
Browser compatibility is one of the underlying promises that libraries—especially the big ones that Jeremy references, like React and Bootstrap—make to developers.
So again, it’s browser incompatibilities that made libraries attractive.
Jim Nielsen responds with the same message in his post Trusting Browsers:
We distrust the browser because we’ve been trained to. Years of fighting browser deficiencies where libraries filled the gaps. Browser enemy; library friend.
For example: jQuery did wonders to normalize working across browsers. Write code once, run it in any browser — confidently.
Three for three. My question has been answered: people gravitated towards libraries because browsers had inconsistent implementations.
I’m deliberately using the past tense there. I think Jim is onto something when he says that we’ve been trained not to trust browsers to have parity when it comes to supporting standards. But that has changed.
This approach isn’t a sustainable practice, and I’m trying to do as little of it as I can. Jeremy is right to be suspicious of third-party code. Cross-browser compatibility has gotten a lot better, and campaigns like Interop 2022 are doing a lot to reduce the burden. It’s getting better, but the exasperated I-just-want-it-to-work mindset is tough to uninstall.
I agree. Inertia is a powerful force. No matter how good cross-browser compatibility gets, it’s going to take a long time for developers to shed their suspicion.
Jim is glass-half-full kind of guy:
I’m optimistic that trust in browser-native features and APIs is being restored.
He also points to a very sensible mindset when it comes to third-party libraries and frameworks:
In this sense, third-party code and abstractions can be wonderful polyfills for the web platform. The idea being that the default posture should be: leverage as much of the web platform as possible, then where there are gaps to creating great user experiences, fill them in with exploratory library or framework features (features which, conceivably, could one day become native in browsers).
Yes! A kind of progressive enhancement approach to using third-party code makes a lot of sense. I’ve always maintained that you should treat libraries and frameworks like cattle, not pets. Don’t get too attached. If the library is solving a genuine need, it will be replaced by stable web standards in browsers (again, see jQuery).
I think that third-party libraries and frameworks work best as polyfills. But the whole point of polyfills is that you only use them when the browsers don’t supply features natively (and you also go back and remove the polyfill later when browsers do support the feature). But that’s not how people are using libraries and frameworks today. Developers are reaching for them by default instead of treating them as a last resort.
I like Jim’s proposed design princple:
Where available, default to browser-native features over third party code, abstractions, or idioms.
(P.S. It’s kind of lovely to see this kind of thoughtful blog-to-blog conversation happening. Right at a time when Twitter is about to go down the tubes, this is a demonstration of an actual public square with more nuanced discussion. Make your own website and join the conversation!)
