海外TECH	DEV Community	Stay alert	https://dev.to/richharris/stay-alert-d	Stay alertA short while ago Chrome broke the web by disabling alert confirm and prompt dialogs from cross origin iframes The justification was that the current UX is confusing and has previously led to spoofs where sites pretend the message comes from Chrome or a different website removing the feature was deemed preferable to fixing the UX But legitimate uses were affected too Users of CodePen the widely used code sharing site co founded by Chris Coyier suddenly discovered that they were unable to use these functions in their projects since CodePen runs your code inside a cross origin iframe to guard against XSS attacks Reports from other sites followed and in the ensuing chaos the change was rolled back until Hidden in the replies to Coyier s tweet was a surprising statement from Domenic Denicola an engineer on the Chrome team It s best that such teaching sites be prepared for the eventual end state where these are removed from the web platform entirely Wait what Reading the intent to remove thread confirms that this is indeed Chrome s stance blocking dialogs including onbeforeunload were a mistake and their future removal is a fait accompli After I tweeted about the situation last week my notifications tab became a Boschian hellscape so I m hesitant to write this post But there are several aspects to this story that are too important for us not to talk about It s not just a story about unloved APIs it s a story about power standards design and who owns the platform ーand it makes me afraid for the future of the web OnrampsFacebook s Dan Abramov pointed out that the changes nuked many programming tutorials Google s Emily Stark suggested they should use the lt dialog gt element instead For the moment we ll gloss over the fact that lt dialog gt is sufficiently flawed that Denicola floated removing it from the spec ーor that MDN s suggested fallback for browsers that don t support it is none other than alert ーand instead consider what this would look like in real life Often when I m teaching people web development they begin learning JavaScript by building a simple number guessing game along these lines function game let number Math ceil Math random let guess prompt Guess a number between and guess Number guess while guess number if guess lt number guess prompt Too low Guess again else guess prompt Too high Guess again guess Number guess alert That s right The number was number game It s pretty straightforward looking stuff but in the space of a few lines of code the students are exposed to many unfamiliar concepts Data types strings vs numbers and converting between them Functions both built in and the ones you write yourselfLoops and if else statementsOperatorsIt s a popular lesson and even foreshadows future discussions of algorithms the smartest students soon intuit that they can win by conducting a binary search but it s hard ーeasily an hour s worth of material Imagine now that before they could complete it they were required to learn about the DOM event handling and asynchronous programming Educators gravitated towards blocking dialog APIs for a reason Failing to understand why these APIs are so valuable in an educational context is inevitable if you don t consider teachers part of your constituency when designing standards It s cliché and only partly accurate to say that the web used to have better onramps for developers but there s truth behind the nostalgic grumbling the web platform s learnability has long been essential to its success We damage it at our peril Hidden signalsThe primary signal Chrome uses to determine whether something can safely be removed from the web platform is the number of page views impacted A feature appearing on of page views is considered small but non trivial usage Cross origin alert is at around significantly above this threshold with same origin the figure is x higher still It s easy to overindex on the things you can quantify especially if you re Google But not all things that count as uses of some feature show up in the data when the data is predominantly public facing production websites Teaching is one such case There are others For example I ve had several experiences in which a well placed alert was the only way to test hypotheses during debugging In an ideal world we d all have well stocked device labs and be able to remotely inspect our code wherever it s running no matter how imminent the deadline Reality isn t always so accommodating Even when my code is working as intended ーit happens sometimes ーI m likely to reach for alert before adding complex error handling if I m building something for myself or my coworkers and I expect errors to be rare occurrences And security researchers frequently use alert to demonstrate vulnerabilities Yes in future they could use something less concise and less visible like console log but in the meantime years worth of literature would instantly fall out of date if alert vanished All of these are legitimate uses but none will affect the metric that determines whether they re important enough to be supported by Chrome Even when we do focus solely on production websites usage doesn t necessarily correlate with importance as noted by Dan Abramov BreakageAccording to Emily Stark a security expert on the Chrome team breakage is something that happens often on the web But if that s true it s very largely because of Chrome For a long time don t break the web was considered something of a prime directive in standards work Recall smooshgate a proposal to add a flatten method to Array prototype turned out to be a breaking change because an ancient version of MooTools still in use by a handful of sites added its own incompatible flatten Disappointingly some developers argued that breaking the web was acceptable but TC took its backwards compatibility responsibilities seriously and ended up renaming flatten to flat instead Google s Mathias Bynens wrote As it turns out “don t break the Web is the number one design principle for HTML CSS JavaScript and any other standard that s widely used on the Web This time around the approach was rather more cavalier Reasonable people can disagree about the balance of priorities when considering breaking changes but it s good to be clear eyed about what breakage means One of the many anecdotes I heard in the wake of the cross origin alert changes stood out I was attempting to delete my recurring payments account from my local waste management s super old school site I was bit by the cross domain confirm in Chrome I switched to Firefox to complete What if Firefox was no longer an option either because a cash strapped Mozilla had stopped developing it or because they had implemented the now standardized spec changes We re not talking about the Space Jam website rendering incorrectly we re talking about people being unable to use essential services on the web A frequent implication in the discussion last week was that website owners could simply re engineer their apps to not use blocking dialogs regardless of the cost of doing so But many sites are no longer maintained and they re no less valuable because of it We can t normalise the attitude that collateral damage is the price of progress even if we accept the premise ーwhich I don t ーthat removing APIs like alert represents progress For all its flaws the web is generally agreed to be a stable platform where investments made today will stand the test of time A world in which websites are treated as inherently transient objects where APIs we commonly rely on today could be cast aside as unwanted baggage by tomorrow s spec wranglers is a world in which the web has already lost What if alert is good actually We re often reminded to use the web s built in form elements instead of recreating checkboxes and buttons with a lt div gt salad Not only are they more accessible than what you d likely build yourself the visual consistency makes your app easier for users to navigate even if you consider the default appearance ugly Yet when it comes to dialogs the ugly default is treated as a bug rather than a feature Why As Heydon Pickering puts it Using alert prompt and confirm in an MVP is the closest most devs will get to providing accessible dialogs Chrome removing them just cuts out that step Devs can go straight onto building their own underperforming inaccessible dialogsIn the bad old days the behaviour of alert was somewhat obnoxious ーit would focus the tab in question and prevent you from navigating away Thanks to years of hard work that s no longer the case to the extent that I d argue alert is in many cases better than whatever you d have cobbled together yourself There are security issues with cross origin iframes I remain unconvinced that removal is a better solution than improving the design in a way that makes their provenance clearer Who owns the web A common response to last week s kerfuffle was use Firefox But that s not a solution Even though the change was proposed by Chromium the intent to remove preceded any discussion with other browser vendors Firefox ultimately supported it That s all it takes for something to become a standard ーsupport from two vendors and stated opposition from none Put differently when it comes to web standards browsers call the shots exclusively Whenever I ve questioned the wisdom of this or that proposal I ve been told I should simply get involved in the standards discussions ーthey re right there on GitHub But openness means nothing without the power to effect change and browsers have all the power This should strike us as odd ーthe WC s priority of constituencies explicitly states that the needs of users and authors i e developers should be treated as higher priority than those of implementors i e browser vendors yet the higher priority constituencies are at the mercy of the lower priority ones Chrome developers argue that they are acting in the interests of users in this case but this thread from Mike Sherov makes a convincing case that this is a fig leaf for the real motivation which is technical debt Meanwhile we don t seem to be learning from the past If alert is fair game for removal then so is every API we add to the platform if the web s future stewards deem it harmful Given that you d think we d expand the platform s surface area with extreme caution instead we re adding APIs at breakneck speed to the almost guaranteed detriment of its future stability Given Chrome s near monopoly control of the browser market I m genuinely concerned about what this all means for the future of the web An ad company shouldn t have this much influence over something that belongs to all of us I don t know how to fix the standards process so that it s more representative of the diversity of the web s stakeholders but I m increasingly convinced that we need to
