Have Single-Page Apps Ruined the Web? | Transitional Apps with Rich Harris, NYTimes

The backlash to modern front end development is gaining steam, with good reason: single-page apps have ruined the web. Can we rescue it without going backwards? In this talk, Rich Harris presents a way to do just that. Rich Harris is a graphics editor at the New York Times, where he builds JavaScript apps to help explain the news. He is also the creator of Rollup, the JavaScript module bundler, and Svelte, the front end framework.
What’s wrong with Single-Page apps? There are a lot of critiques. A non-exhaustive list of terrible things about single-page apps include:
You’ll need a bloated JavaScript framework and performance will suffer
It comes with complex tooling and is less resilient, since it won’t work without JavaScript
It will be buggy and accessibility issues
JavaScript failing is a fact of life. So what’s a developer to do? SPAs solve problems to the traditional approach, but are still problematic. Rich presents a new framework for thinking about how we can get the best of both the MPA and SPA worlds: transitional apps.
What’s a transitional app? Transitional apps samples elements from both traditional and modern architecture. The term is borrowed from interior design’s framing of “transitional design.” Transitional apps are, like multi-page apps, server-side rendered for fast initial loads, resilient since they work without JS by default, and provide a consistent experience with accessibility features built in. But like a single-page application, they also have a single codebase, fast navigation, persistent elements, and client-side state management.
Learn more about transitional apps, and how to get the best of both worlds in Rich’s talk.

Traditionalist here. IMO the most valuable part of this vid by far is you explaining the use cases for SPAs. I'd pay money for access to vids that just explain use cases for different tools/technologies like this. I.e. show me clear mocked up examples of what actual new functionality is made possible by this tool, with explanations for why those features were not possible before. Its amazing how hard that can be to come by. I think framework advocates avoid giving those examples because it makes it makes the framework seem less profound and it makes it easier to understand when you don't actually need that framework. So thanks.

SPA ruined Ctrl+Click navigation for power users :(. In the past, I was so used to holding ctrl + clicking links to open them in separate tabs, now that don't work anymore. You now have to "duplicate" the tab and then hope it opens to a state close to where you were. Simply put for a power user that is good at using shortcuts including Alt-Tab to switch between windows (and yes tabs if you separate your one tab from the rest) or Ctrl+Tab (Ctrl+Shift+Tab) to move back and forth between tabs.

[@owenpalmer8242]

It's not even that hard to add that functionality to an SPA, they should add it every time if they really can't do MPA

[@dogoku]

What you are describing is HTML fundamentals in my opinion. The problem is not SPAs, it's that devs these days are further away from HTML than before, because of frameworks that abstract away everything. Devs need to learn to use anchors for what they are meant for (linking to content) and how they are meant to (not as a button) and keep as much state as possible related to the URL (i.e deep-linking). I try to enforce and teach both those things as much as possible to my teams. If you have the right fundamentals, it should take the same amount of time as doing it the wrong way

[@bernarddt]

@@dogoku "it's that devs these days are further away from HTML than before" This is probably more accurate, I'm also pro-fundamentals. If you want to be professional in your work you have to understand the basics of what is expected or the norm in your coding domain. For instance, in the past, I've seen so many Windows Forms-based (.net) apps that don't correct "tab" navigation. So if you again use the app and "tab" navigate you jump all over the place. Even after Microsoft spent a lot of time to make it easy to correct this, no one bothers in their apps. I currently dub this as "Rapid Prototyping Coding", vs. "Release Coding" vs "Maintenance Coding".

[@bernarddt]

​@@owenpalmer8242, I think the aim of the video is that when you code MPA's you don't need to implement these features the browser has them covered already. Now with SPA, you have to specifically add these features back. Even though we can argue that it is easy or a framework may automate it. Also, I'm wondering how far should you go? Because for instance a dynamic HTML content that gets loaded after the page is loaded, should you now also include the "state" of controls? (Like whether a checkbox is checked or not). You end up basically capturing all dynamic changes in the URL or some client-side storage. I would say go all in, but coding a huge SPA this way may be time-consuming. (Again compared to the MPA where the browser already handles this).

[@owenpalmer8242]

@@bernarddt I agree with a lot of that, and would even say that in a lot of cases, MPA with minimal styling (essentially retro web) is the most natural and the superior way to develop sites. Unfortunately, this does not hold true for a lot of the demands of the user. Not everyone enjoys jumping around a site using only tags and hrefs, regardless of how much easier that would be for devs.

The single-page in fact is what the web should be since the introduction of Javascript. As a Creative Developer from the Flash Player era I know the only concern about this was the indexing and analytics metrics, so to do this they simply killed FLASH so we lost about 10 years of multimedia rich and artistic content the Flash already was delivering, including GPU features. So now finally we're back to the same place where WebApps are eliminating the need for NATIVE Apps and still some ignorant think static text-like documents will lead to evolution. But I guess this time the WebApps + WebAssembly + WebGPU will simply kill the need for App Stores and the Backend and Native developers will need to adapt.

[@bryanlee5522]

I always noticed that some sites behaved weirdly and were really annoying to navigate (especially the mouse wheel click that opens the page in the same tab or sometimes not at all is a real pet peeve of mine) but I didn't have the knowledge or vocabulary to pin point why I hated them. I also appreciate that you tried to stay as neutral as possible and presented both advantages and disadvantages of both models.

[@bluecafe509]

The Rails solution (hotwire) is the one I have been doing for years, except with PHP. Partial page updates are easy and very effective. I was an early adopter of React (and Flux). Back then installing all the dependencies was a nightmare. Now React has packaged everything together, which makes life easier. Still, SPAs and modern web development force you to depend on packages that are constantly being updated, or that may no longer be maintained. This can leave your app vulnerable. God forbid you should step away from your project for a month and come back to it later... Pray that all the packages still work and can be updated.

They commit to "story points" for delivering exactly the functionality specified by the customer or by their "product owner". If the product owner described how the back button should work and etc, and the devs committed to delivering it, then I'm sure they would get what they asked for. If they didn't specify how they wanted the back button to work, or didn't view that as valuable enough to consider or to commit story points to, then they likely didn't get it. Developer knowledge or ability have nothing to do with it. This conversation is entirely about power structures within the industry.

Design and engineering should always be about what the application is first and tooling second. How much of any tool or technology is needed shouldn't be a fashion statement about whether one likes something or not. It makes sense for Google Maps to be a one page app. It makes sense for Wikipedia to use HTML links because of its high reference capability, the original design intent of HTML links to begin with. Web development is far more fashion industry than engineering and that's the real problem.

[@ABaumstumpf]

While i already loath those JS-ridden sites that take enormous amounts of computation and time to finish loading, i find it even worse that web-developers now start claiming their websites to be Apps - no, those are very different. Making a website that works correctly with multiple pages while still keeps track of various things like where on a continuous-loading page you were or keeps playing music is impossible with multi-page sites? Since when? Why are you making such claims? That has been done with good old PHP like 20 years ago already. It is not even hard. Even worse is that now many pages you tons of JS just for simple things like mouse-over captions for images - dude, that is base HTML and does not require any scripting. Many single-page websites nowadays take longer to load AND are slower to navigate than sites from 20 years ago where we had far slower machines and internet. When a modern PC takes 5 seconds to fully display a page that mostly consists of text - image just how long that would have take on something like a Pentium 3 with 300kbps ISDN (current machines are literally hundreds of times faster).

[@imnoodlehaus]

I left front-end development after 18 years because of the explosion of frameworks and rendering models client side. Initially, I was happy with the popularity of Node and NPM. I appreciated the tools that it allowed me to optimise package sizes of my bundles. But then React happened. Then WebPack. I just couldn't keep up with the complexity. The mental overhead you just have to deal with on how to model interactions and data movement on the client side is just too much. All this on top of the complexity of setting up your build and bundling pipelines that change almost every few months because of the latest and greatest. Then permute these interactions with all the device form factors you want to support. Combine that with the mid-tier and back-end APIs you have to develop to support your interactions. It's crazy. Have moved to back-end development, and I'm now back to enjoying software engineering again.

I agree. It's kind of important to keep the SPA's functionality, or the user stories and UX, really simple (Develop, deploy and run away). And I try to avoid switching frameworks, or adding any new dependency. It would result in task switching, what is very taxing for cognitive performance. There are max 1.5 things someone can become very good at. 1 thing that currently pays the bills, and a 0.5 thing that might pay the bills in five years. Everything else must be delegated, outsourced, or removed from the wish list.

Interesting talk. The 'single-page apps have ruined the web' line is hyperbole. A major reason frameworks are used is to handle the problems that pop up when building complex apps, I think he overlooked that. Although this kind of turned into a Svelte infomercial I will actually be giving it a look. So many of the framework and SPA guys I pay attention to are always raving about it.

[@growlydog]

Complex apps! A crud admin panel isn't complex, so why default to React or Vue? This is the problem I see - far too many front end devs are "React Engineers" and default to it for everything no matter how simple the requirements are. I've seen teams spend weeks building out backoffice front-ends that have no hard requirement for any JS at all which could've been built in server rendered templates in a single day (Rails for instance).

[@ighsight]

@@growlydog I don't see your point. Are you saying all "complex" apps are mere "crud admin panels"? Obviously not true. Should such a basic panel be built using React? Obviously not. That leaves us the possibility that there are apps more complex than admin panels that might be best built using a framework. It's not hard to imagine such use cases and you haven't made a convincing point against that. I get the criticism against over-engineering, but the implication seems to be that all uses of frameworks are instances of over-engineering. That thinking seems to just willfully ignore the legitimate reasons that devs/teams decide to use frameworks.

[@growlydog]

@@ighsight I'm saying that, in *my experience*, over a decade building web apps, I have seen my teams at multiple companies become teams of React engineers that have forgotten that there are simpler, faster technologies to build with. So when we have a simple CRUD form, or an app that lacks a need for dynamic functionality, as is typically the case with backoffice front-ends like admin panels, they still invest extra effort in React instead of just doing simple server side rendering. I think you interpreted my original comment to be the opposite of what I was saying. Admin panels are typically simple. Some apps need more complicated tooling to build, like the Spotify app for instance. But a back office tool for a user to search for a user account for customer support should probably be server rendered, until there's an express need for app like behavior.

[@growlydog]

My point was really "Frameworks have become the default for everything regardless of complexity, and that is a bad thing. There are still plenty of common use cases where frameworks add unneeded complexity and we should revert back to simpler rendering in those cases"

[@ighsight]

@@growlydog I think I did get your point- devs/engineers often use a framework to over-engineer a solution for a relatively simple use case or problem. I didn't see how that was an effective response to my original point- sometimes using a framework is the best solution for what you are doing since what you are building is relatively complex. I'm saying this talk did not address how a "transitional app" would be better than a framework for that situation.

Apparently I've been building transitional apps, and thinking they were SPAs the whole time. I've never regarded it as a departure from SPAs - more of a best practice.

[@chris94kennedy]

I'm confused by this - if you have to inject javascript into a root HTML page vs delivering individual HTML resources how can you think you're doing one over the other? SPAs are always built with frameworks like React or Angular, were you not using one of those? Not trying to be annoying just interested.

[@goldfishbrainjohn2462]

​@@chris94kennedy SPAs are about not rendering HTML page on the server side in advance. It means you can do it with only vanilla JS. Frameworks are just more convenient and they can speed up your development becuase they have solved problems you would likely encounter when developing vanilla JS SPAs.

[@MadsterV]

PS: turns out you point most of these out towards the end of the video, which was a relief. I get that you're trying the point of view of someone who rejects SPAs (as I did years ago before figuring out the benefits when scaling), but still I want to throw in my 2c. - you will need a JS framework : yes, unless you want to build it from scratch yourself. You can do that to if you're so inclined. Many people use Laravel for PHP, same deal. Building frameworks is a lot of work and most will use an estabilished one. - Performance will suffer : not if you do it right, at least, not noticeably. - It will be buggy : as buggy as all your other stuff is - Accessibility issues : again, not if you do it right (care for your markup! use ARIA! ) and just the same accessibility issues as your other stuff. - Complex tooling : yeah, this is the price paid for being able to use and extend languages that are not implemented in a browser. It's complex but most people will not have to touch the complex parts. - Less resilient - it won't work without javascript : it also won't work for WAP. This is not an issue and hasn't been for over a decade Sure, once you move from writing documents to writing software you have the hardships of software. You have the same issues if you're writing server code. Ask yourself: what's my target audience? if you're targeting 2g, there's a lot of other concerns that have nothing to do with SPA, but with the fact that you are dealing with really old tech and bandwidth. Maybe you can't use CSS, SVG or even images either! and if you're targeting terminal users, maybe skip html altogether? always design for the end user. On the second vs list: - MPA is server-side rendered, but you can have server-side rendered SPA too via hydrate. Also, the point of SPA is freeing capacity on the server and serve it via a CDN on a leaf near you, which outperforms a centralized MPA, specially after the first load when the bundles are cached. - SPA typically have poor initial load performance, because they're not done right. Pre-render what you can, split your bundles and lazy load, don't repeat server calls for the same info, don't block the entire UI for a single component's loading, etc.... I'm sure there's more good practices I missed there. All of these help with bloat, specially on large apps. You could also checkout microfrontends for an alternate take on the issue.

As a developer who has built both MPAs and SPAs where SPAs shine is with cloud business applications. Being able to modify a single page and swap in different elements based on user input selection is very attractive to customers and provides a very clean UI experience. The modern website as we know it which is largely limited to News and Blogs doesn’t really need SPAs. Wordpress solved all those problems years ago. Variations of this of course are social media and e-commerce sites and e-commerce sites are all plug and play templates and the average person really doesn’t need a social media site. Lastly one of the biggest pushbacks for SPAs that I know of is developers tend to be lazy. They really just don’t want to spend years learning a new framework like angular.

I have been a full stack web dev for a very long time and only got to building very basic SPA's very lately, right before I moved to backend only dev, where I have come to understand and appreciate separation of concerns and other backend dev tricks. So now I am really convinced that frontend and backend should be completely separate and only communicate by API. But that being said, as a user, I hate most SPA's :) I think browsers and websites have gotten more and more bulky and slow and trying to do too many things that they shouldn't. One thing is to load some partial info from the server, and a completely different thing to render everything from JS. As a user, I would appreciate it more if my device used less CPU, less heat, less battery, when simply opening up a webpage! You guys need to figure this shit out :)

I work on software development teams and SPA often requires an entire team of front end devs due to the added complexity of front end frameworks (React, Angular, VueJS) and it is hard even as a full stack developer to be a master of the complexities of both a front end and back end code. You end up with crops of new pure front end developers who don't even know how to join tables in SQL. NPM and the large number of packages required adds a huge number of dependencies.

[@lonbpalmer]

First, I loved this talk and I love Svelte. However, saying that the anti-JavaScript movement is cultural and not technological really ignores the absolute productivity killing "features" in JavaScript, like truthiness and the ability to simply reference properties on an object that aren't there. This makes large projects simply unmaintainable. JavaScript isn't the DeFacto language of the web because it's useful, it's because it had momentum. I don't want to turn this into a JavaScript debate but that point in particular is garbage and Vercel isn't going to change that with their edge functions. As long as engineers care about maintainability of large applications, JavaScript will always be an absolute risk to any program.

[@ngong01]

My webdev stack is static vanilla HTML, JS and CSS and Go for the webserver. I almost never use 3rd party libraries in my JS. I also use the HTML template tag more than anything rather than server sent page content. Just fetch data from the server, and have functions to clone the proper template and populate the page.

[@CyReVolt]

On the desktoo, we talk about entry point. It's just that for websites, the payload to determine the entry point is made of parts of the URL, i.e., paths, GET params, etc.. Anyway, simply put: Noone wants to pay for great UX, they just want something to milk. Product managers aren't technically savvy yet don't let engineers drive the work.

[@adaliszk]

I believe you an do some SPA/PWA stuff in a traditional way as well with a fairly minimal effort: Using ServiceWorker, and some clever navigation replaced transitions just by hooking into existing events you can more-ore-less imitate how a bloated webapp behaves. Like, there is even a callback for Custom Elements for adopting their state/render when they are moved to a different document. And that's today, not the proposal solution for page transitions :)

[@nomadshiba]

you can give paths to modals and they appear when the path is the modal's path, modal appears automatically. when you wanna close the modal you do history.back() and it closes. or the user can press back themselves. if you refresh the page while the modal is active, the modal just opens automatically as expected and modal can either pick the page at the back or it can load main page at the back.

[@VanjaMk1]

This seems a bit biased view towards MPA. I keep seeing this argument everywhere. But SSR isn't necessarily faster - it still depends on the request speed. If that request is slow, you will see a big nothing (vs SPA where some layout will be visible + loader). If we are talking about statically generated page, then of course it is faster, but that is not SSR. Accessibility, for the most part, has nothing to do with SPA vs MPA conversation.

It makes no sense to make apps for the web in most cases, you should just make a native app for your target platforms when you actually need an app. I never knew single page apps were a thing until I got into web development and that's how it is for most consumers, they don't care too much if your site loads/navigates with a fancy transition or just abruptly. A common user expects the web to behave like a series of linked pages, we have apps to behave like apps.

[@diamanteduul8084]

"A common user expects the web to behave like a series of linked pages" I have to disagree here. For people who have been on the internet for a significant time yes. But in modern times, the average user is on their mobile. Meaning its the other way around. They expect the web to behave like apps. In this day and age for the majority of cases, not developing for mobile is a big mistake. I don't like web apps either, but one reason for them is convenience. You Only need to make 1 platform, with a single code base. It would 'work' both on web and mobile. The alternative is to code a separate native app, with its own programming language, and nuances which would take time to learn (or you can hire someone to do it). Now you have 2 things you need to maintain. If you ever decide to update your app, you will have to update the site too. and vice-versa. All of this will cost time and money. Native can be superior in every way to web apps. But their cost in resources and time make them less convenient than web app. It's as you said. People won't care how the website is made under-the-hood, as long as it works. If a webapp can get 70% close to a native experience, they won't care if their content takes an extra half second to load, or if things don't work as expected from time to time.

[@bryanlee5522]

I don't think you realize how many things on the internet are 'apps'. This site you are using is an SPA. What exactly is an app anyway? I thought a website means something that is basically just html. An App is anything functional and dynamic outside of what is possible with plain html. I think you aren't thinking about this very well. An SPA doesn't have to do with routing, that's actually a 'weakness' of SPA where it actually mimicks regular routing to seems more like a website (otherwise the url would never change and you couldn't go back or forward). So I think you're confused if you think an SPA has to do with page transition. It has to do with having freedom for a site to have increased User experience and functionality. For example, compare youtube commenting with 4chan and tell me which is better. 4chan you have to reload the page to see your comment. On youtube it magically just posts in real time.

[@falias4]

It totally depends on the page... you can't compare a company homepage with Instagram or similar. I think about it that way: I don't build websites/apps for the web. I build them for the browser. I am constantly switching between devices and want to access my stuff from everywhere.... and every device nowadays has a browser with mostly the same standards. Also that "A common user expects the web to behave like a series of linked pages" might apply to older generations ;-)

[@phee3D]

@@falias4 I don't think so, I'm quite sure the common user still can't tell if they are using an MPA or SPA because they don't care as long as its fast. Which is why most websites are still MPAs including very big ones like amazon, stripe etc but I do agree it can SOMETIMES make sense to make a web app like figma and youtube.

[@bryanlee5522]

@@phee3D ​ They can't tell because the developer purposely makes it seem like a normal site. It's also possible that a new form of site will be popularized in the future, and we won't have to make an SPA seem like a normal site. I tend to see this on some personal websites that have a very unique user experience. SPA basically allows for total freedom, which is going to be necessary for the future when VR / AR / metaverse type stuff starts becoming more popular. The idea of clicking links to go to a new page is going to seem extremely archaic in the future. I mean the concept of a 'link' in itself is just an invention for the limits of a particular technology. Hydration has the same concept of a link, except it brings in data on demand when needed, rather than all at once. Which is really the proper flow of data to user.

[@alivenumber5]

I don't think it's single-page vs multi-page. Instead it's client-side vs server-side view state management. I've found over time that it's best to pull the state management back to the server in most cases unless you absolutely need instant transitions. But if the state changes it's generally good if the server finds out anyways. So perhaps a combination is the best bet. On click of a button it should instantly change color (or whatever), but the complex state changes should still have to hit the back end for the sole reason that there's a maximum amount of state you really want to send up front anyways. Lets say a table with 10 viewable entries. Paging forward should instantly give feedback with an initial small change and possible loading animation, but the query should only return lets say 20 results, the queued results and the viewed ones. A click should show the queued results, but still hit the back-end for the next queued results. Best of both worlds!

You're not going to make a traditional website without javascript so being able to load a site without it is a poor point to argue. The speed of first render can be a problem but you're going to have that problem with a mpa when bandwidth or server resources are limited. Saying you can't persist data while navigating in a MPA is also incorrect when you consider local caching like using local storage. You can also get around the not being able to play media in a MPA by using s.

You're point about maintaining two applications in the MPA area is absolutely correct. Anyone who has had to deal with branding updates with the traditional MPA model understands the pain involved. It's equally easy to get MPAs wrong as it is to get SPAs wrong as well. The reality is that with highly scalable applications, the back end is served by a fleet of microservices that spin up and down based on demand. In order to manage the network load on highly interactive sites with millions or billions of users, it is of paramount importance to reduce the traffic over the wire. The strength of the SPA lies in the fact that all style and interactivity is self contained--and outside of the initial download of the JavaScript (which can be cached), we are only ever trading data between the client and the server. Whether that's in JSON, or Protobuf isn't what's important. It's the fact that we aren't sending potentially heavy HTML snippets (worse with HTML + JavaScript). I am interested in seeing what the Transitional App concept brings to this scenario.

[@SaHaRaSquad]

11:07 SPAs are just as affected by page load latency. Whether I look at a more or less blank screen or at blank UI placeholders because the SPA needs to load stuff for 2 seconds doesn't make a difference for the user. The real performance issue are wrong priorities, and those cannot be fixed by technology. Until that's fixed (probably never) I will always prefer traditional web apps, because those at least respect my middle mouse button. I don't care what paradigm you use, if you ignore my middle mouse click or open a new tab in the foreground your site is a UX nightmare and you should feel bad.

[@ramireznoy]

That's a really interesting and thoughtful analysis. But somehow I can not stop thinking it is like re-inventing the wheel. Getting chunks of the page and the page logic is something we considered normal and common in the golden age of jQuery. Getting a modal content and form validator, a menu content and animations, a notification content and interactions was something very common 12 or 14 years ago. Of course, the point of the multilanguage issue was a problem, amplified by the use of many template engines all over the place. Making portability a huge issue. In any case... As we all can recognize the need for SSR and the advantages of SPA... Why not to have Svelte (It could also be applied to Vue and React) working as a template engine instead of isolating itself as a SSR capability? I think current SSR support is the one increasing the gap here, not solving any issue (most of the time you could get away easier and faster with smart code splitting). It is fine if SSR applies for a number of cases and you can use it, but the real power tool will be to also include template engine capabilities. Imagine being able to parametrize every page load as you wish but from you business logic.

[@TheJacklikesvideos]

I can't talk about the modern problems of web front end so calmly and non-vulgar. I remember when computers would have more downtime between normal instructions than users would.
