I'm still struggling to get on board with this. It seems to just favor speed above all else. I found the linked article at http://www.smashingmagazine.com/2015/11/modern-static-websit... to be a bit more helpful in pitching the case, but even so it seems like just pulling the complexity of dynamic sites into the build stage of the static ones all because writing efficient DB queries is "hard". For a companies front page, I can see the benefit of generating content once instead of for every client, but what happens when you need to present information beyond the generic? What happens when you need to show a user's order history? Let them change their password? Allow them to see the distance of that run?

I feel old and crotchety, but I just find it a bit strange that as we get more and more obsessed with data, this emerges; something that seems less that optimal for dealing with it. They make the comparison themselves, but it seems like reverting from "Web Applications" back to "Web Sites" and just filling it with API calls to actual Web Apps.

The "right" way to do this (edit: this is essentially assumed by the article, so I'm not contradicting it) is to build static sites and use JavaScript to pull in any dynamic information. You run data services that output JSON, then the JS on the page calls those data services and renders the views.

This still allows you to reap the benefits of static content (namely CDN distribution / caching) while still maintaining some dynamic content.

But basically, you do it this way to avoid pulling data that isn't user-specific from the database. It's far more efficient to build a header + page + footer once at build time than to have every client have to do that on access -- even if you have 100+ variations of your site that need to be compiled and updated on any change in the shared content. Storage and compute resource are trivially cheap if they don't scale exponentially with number of users.

Yeah, it's more work for your developers, but it saves your DBAs a LOT of work by reducing the volume of data served from the database. And at the end of the day, it's full-stack effort that counts -- I'd rather have my developers spend 2x the time to build a system than have my DBAs fighting fires because the site went down. With a static site, you can set it to read-only mode if the traffic gets to be too much, and the static content will be handled by the CDN (which can almost certainly handle any load).

Using JS to present data moves the work of generating the display of that data from the build process, as with "pure" static site generation, or from server-side code, as with a standard CMS, to the client, where it is most likely to fail in unpredictable ways due to variances in browser JS or CSS engines, network performance, browser extensions, etc, etc.

But given that the concept of progressive enhancement seems to have been completely lost on the latest generation of web developers, who cares, right?

bosdev2• 11 years ago

To me the logic is simple: It's more efficient to build the site when its content changes (very infrequently) rather than when its viewed (very frequently). Yes various forms of caching can allow you to scale the dynamic model quite far, but scaling gets so much simpler when you move into the static world.

In answer to your questions, the general idea is you have a static site, and a powerful API. The power of the JavaScript engine in modern browsers allows you to build your entire application to run in the browser, sending asynchronous requests to your API as is required. You're essentially just removing the Python/PHP/etc. middleware layer many sites have traditionally had.

What happens when you need to show a user's order history? Let them change their password? Allow them to see the distance of that run?

Well if you can assume the user has javascript enabled, AJAX is an option.

I'm pretty sure they are talking about generating the majority of the site and filling the details in dynamically as needed.

tedkimble3• 11 years ago

There's definitely a point at which an actual web app makes sense. But I think there's also a large category of websites that have been built as dynamic apps even though they’re updated sparingly and only require changes to a few items of content or data.

I recently launched Static Website Manager (https://www.staticwebsitemanager.com) to help bridge this gap between static and dynamic websites. Relevant to this discussion is our Form Responder tool, which provides an endpoint for your HTTP forms.

The cool thing is you can connect them to your Jekyll data files and then new form submission data will be committed (appended or set to a key) to that data file. New commits also trigger builds/deploys, resulting in a dynamically-updated static website. (They work across your branches, too, if you need to moderate submissions before merging with production.)

sneak2• 11 years ago

It looks awesome, and I've been thinking about building a tool just like this one around Jekyll myself.

The pricing is a bit steep - I would be fine with $15/mo/account but I have a half-dozen sites to manage and more all the time. Some of them are low enough traffic that $180/year isn't really justified.

Thoughts?

jlg23• 11 years ago

It seems to just favor speed above all else.

Yes, it seems to be all about speed. But there is one more thing that really convinced me already some 15 years ago to migrate a high profile site to static site generation: Security. The attack surface is reduced to your httpd.

PS: The site did not see too many changes and not many editors - hacking a solution in pmake and some perl for editor UI was done in half a day and everyone was happy, including the sys-admin (me, again) who only had to apply security fixes every 2 years.

PPS: Also, another important reason for some, though for me it was only an afterthought, if at all: Sending a static byte array is much, much more energy efficient than scheduling a meeting with your database for every request.

I want to push back against this idea that "Web Applications" represent uniform forward momentum for the web, while "Web Sites" are somehow archaic. This seems to be a fairly common perception, but it strikes me as a false dichotomy.

Both are distinct and useful things. Static site generation isn't a good solution for interactive applications – conversely, React is a poor choice for building low-interactivity web pages.

EDIT: Improved blockquote formatting.

tarr11• 11 years ago

Looks like the engineers made this decision:

"If you consider the amount of information that changes on a daily, or even weekly basis on a site like wework.com, it is actually quite wasteful to have a server process each and every request that comes through."

A better solution for a marketing site is to use a CMS (doesn't really matter which - Wordpress, Rails, etc) and then use a CDN like Cloudflare to proxy static pages and speed things up. It's fast, efficient, and flexible.

The solution wework used optimizes for performance but reduces flexibility. I'd bet the marketing team at wework wishes that they didn't have to redeploy the entire site every time they wanted to change some text.

seanwilson• 11 years ago

I agree it's less flexible but another benefit is that it's very easy to secure in contrast to a full CMS.

jnbiche2• 11 years ago

It's definitely possible to have the best of both worlds, and services like Contentful and Prismic.io are leading the way there, with easy-to-access Web interfaces to JSON-based content, which is then easily rendered using a static-site generator.

Combined with triggers from a host like Netlify, and it's very easy to redeploy whenever a marketing person makes a change using the Web backend (and some static site generators do incremental builts).

kavok• 11 years ago

With some static site generators you don't have to redeploy the entire site. Just the changed files. You can rapidly update the site with no issues. I'm not sure if a CMS is really a good solution for a site that changes infrequently or when updates typically require developer interaction anyways.

chriswarbo• 11 years ago

With some static site generators you don't have to redeploy the entire site. Just the changed files.

My static site does this. I use make.

bosdev2• 11 years ago

I'm not sure what "redeploy the entire site every time they wanted to change some text" means. When you use a continuous integration tool you don't ever have to manually touch the deploy process, it can happen immediately after you make your change (if you so wish). The marketing team makes a change, the change goes live on the site. The only difference between this and any other CMS are the technical advantages.

detaro• 11 years ago

I'd bet the marketing team at wework wishes that they didn't have to redeploy the entire site every time they wanted to change some text.

Do they actually know/notice that they are doing that?

tedkimble3• 11 years ago

There's a growing market of tools solving this problem. We launched https://www.staticwebsitemanager.com recently, which provides a CMS on top of your Jekyll static site. Plus, each user transparently gets their own staging branch to make and preview changes without the fear of breaking production. You can have your flexibility too!

gotchange2• 11 years ago

This is an abstraction problem and can be fixed easily. The team has to build an interface for the non technical folks at the organization exposing the bits of the API that they deem necessary and appropriate and then handle the complex stuff behind the scene communicating back and forth with other parts of the stack.

captn3m0• 11 years ago

I run my personal sites and a couple other on static site generators (mostly Jekyll) and it really works out well. The most complicated and interesting case is that of hackercouch.com, where we are running custom Jekyll plugins to even serve an API.

Another website, recently setup for the chennai floods by a friend uses a Google Spreadsheet as a database, but is served as a static site: http://chennairains.org/.

Its far more easy to deploy a static site, they are portable and shifting hosts is far more easier. Your database considerations are slightly less relevant since it only affects deploy speeds, and not your site performance.

thecodemonkey2• 11 years ago

Static websites are great of course, and the article outlines that nicely.

The problem that I've been facing personally is that most of the times, the people who are updating and maintaining content on marketing websites are not developers.

So having to use the command line for static site generators such as Jekyll or Middleman is just not a good experience. Don't get me wrong, I LOVE static site generators in general and I'm using both Middleman and Sculpin myself.

Other people has seen this problem too, and some user-friendly-ish static site generators have started to surface, but I want to chime in with a solution to that too since I believe that the best way to adopt static site generators is to use the tools that content creators and maintainers already love and are familiar with, e.g. WordPress which now has a whopping 25% marketshare[1].

I built SpudPress[2] with a friend. It is a hosted static site generator for WordPress. We automatically generate a static version of your WordPress site and host in on a super fast CDN. You don't have to worry about any of the edge cases of generating a static copy, we take care of all that automatically for you.

Movable Type, one of the original blogging platforms, worked (and works) exactly like that, though it also supports dynamic publishing. For example, Jeff Atwood's blog has always been statically generated: http://blog.codinghorror.com/coding-horror-movable-type-sinc...

thecodemonkey2• 11 years ago

That's really cool! I like that. It's nice to see that a platform like Movable Type has had this feature right off the bat for such a long time.

The main reason that we decided to build SpudPress this way, is that you can more or less take your existing WordPress site and instantly make it static.

In contrary to Jeff's Movable Type blog we're taking full advantage of the static pages to host the entire site on a CDN + handle asset cache validation automatically.

One key requirement for us when evaluating different static site generators was the ability to hit an API endpoint and dynamically generate static pages based on the data returned.

...dynamically generate static pages?

lfx• 11 years ago

Yes. Putting in other words - caching (well, some sort).

jnbiche2• 11 years ago

Basically, this means you hit an API endpoint that returns an array of JSON objects, each of which is used to generate an HTML page.

Contentful offers this as a service, along with web frontends for updating the data for those APIs.

gotchange2• 11 years ago

Apparently, their API is structured to work on a per web page basis or even a higher level than that but I could be mistaken.

Dr_tldr2• 11 years ago

Some serious questions:

1. Why not just use fs.writeFile to create all the site info as json files as either a one off or a chron job, then run a gulp task to either use something like jade or else roll your own rendering to put the JSON in the right place on the page, then output the result as html to a public folder, set up an express static server and have a catch-all splat after it for 404s? What am I missing here?

2. If your site is fairly static like WeWork's, why not just have it as a SPWA, set all the links to retrieve a JSON file from the static server and process them on the front end? You could even use history.pushState and checking window.url to make sure that history works and links would load the right thing.

3. When someone logs in, are you doing a DB lookup then serving their dashboard page statically (somehow, for some reason...), or does this static build only apply to part of your page and not others?

4. Could everything Roots does be replaced by one 6 line gulp task? Not trying to be mean, just wondering if its target userbase knows what gulp is.

bobfunk• 11 years ago

For point 1 - that will give you way worse performance than WeWork's current setup, since all requests will have to go back to your origin where your express server is running in order to determine if it's a static request or a dynamic request.

With netlify this happens at the CDN PoP which makes a huge difference for a site with a global audience like WeWork.

Dr_tldr2• 11 years ago

Sure, but that's not an advantage unique to netlify, is it? I mean, one could run the express server on Amazon CloudFront and have the same situation and a more competitive pricing structure. Or is there something else they do that I'm missing?
