Dynamic Websites vs Static Pages vs Single Page Apps (SPAs)
Summary
TLDRThis video explores the various methods of modern web development beyond single-page applications. It discusses the use of static websites for simple content, dynamic websites for user-generated content like blogs and online shops, and single-page applications for an instant, app-like experience. The video also touches on the pros and cons of each approach, such as SEO challenges with SPAs and the performance benefits of server-side rendering.
Takeaways
- đ The video discusses three main approaches to building modern websites: static websites, dynamic websites, and single-page applications (SPAs).
- đ Static websites are the oldest approach, consisting of HTML files served directly from a server without any server-side processing.
- đ§ Dynamic websites involve server-side rendering where HTML code is generated on-the-fly in response to user requests, often used for user-generated content or frequently changing content.
- đ± Single-page applications are the most modern approach, inspired by mobile apps, providing an instant and interactive user experience with minimal page reloads.
- đ ïž For static sites, tools like static site generators can automate the process of generating HTML files from data sources, suitable for content that doesn't change frequently.
- đ The video mentions Gatsby as an example of a tool that can turn a React app into a static site, which is then enhanced with SPA features after the initial load.
- đ Dynamic websites are beneficial for SEO as search engine crawlers can easily index the fully rendered pages served by the server.
- đ SPAs offer high reactivity and a seamless user experience but can pose challenges with SEO and performance on slower devices due to the reliance on client-side JavaScript execution.
- âïž Server-side applications are advantageous for distributing the performance load to the server, which is helpful for maintaining good performance on user devices.
- đïž The choice between these approaches depends on the specific needs of the website, such as the frequency of content updates, the need for dynamic content, and SEO considerations.
- đ The video emphasizes that there is no one-size-fits-all solution and that each approach has its own advantages and trade-offs.
Q & A
What are the three main approaches to building websites mentioned in the video?
-The three main approaches are building a static website, a dynamic website, and a single page application (SPA).
What is a static website and how does it work?
-A static website consists of HTML files that are served directly from a server to the user without any server-side processing. It's the oldest approach and suitable for content that doesn't change frequently.
How does a dynamic website differ from a static website?
-A dynamic website generates HTML code on the fly per request on the server, allowing for user-generated content or dynamic content that changes frequently, unlike static websites that serve pre-written HTML files.
What is a single page application and how does it provide a mobile app-like experience?
-A single page application (SPA) loads a single HTML file and uses JavaScript to fetch data and build the entire page dynamically in the browser, providing an instant, app-like experience without the need for page reloads.
What are the advantages of using a static site generator for a website with changing content?
-Static site generators can pre-generate HTML files from data sources like databases or markdown files, making the site fast and SEO-friendly while reducing the need for server-side processing.
How does a dynamic website handle incoming user requests?
-Dynamic websites use server-side languages and frameworks to parse incoming requests, fetch data from a database, and construct HTML pages with templating engines, which are then served to the user.
What challenges might single page applications face regarding search engine optimization?
-Single page applications can struggle with search engine optimization because search engine crawlers may not execute JavaScript, which is often used to render content in SPAs.
Why might performance on slower devices be a concern for single page applications?
-Performance on slower devices can be a concern for SPAs because they rely on downloading and executing JavaScript code in the browser, which can be resource-intensive.
What is the role of a templating engine in dynamic website development?
-A templating engine defines the structure of HTML pages and specifies where dynamic data should be inserted, allowing the server-side code to stitch together data and templates to generate HTML pages.
Can you provide an example of a tool that combines the benefits of static and single page applications?
-Gatsby is an example of a tool that builds a React app as a static site, which is then pre-rendered by services like Netlify. This combines the benefits of static sites for SEO and performance with the interactive experience of SPAs.
What are the trade-offs to consider when choosing between these three website building approaches?
-The trade-offs include the need for server-side processing, the ability to handle dynamic content and user-generated content, the impact on browser performance, the speed of page loads, and the effectiveness of search engine optimization.

đ Exploring Modern Web Development Options
This paragraph introduces the video's focus on the various methods available for building websites in the modern web development landscape. It emphasizes that beyond single-page applications, there are other significant approaches to consider. The speaker intends to discuss these alternatives, providing guidance on when to use each. The video is complemented by an article with additional information, and the speaker encourages viewers to subscribe, like, and share for more content.
đ The Evolution of Web Development: Static to Dynamic Sites
The speaker delves into the three primary types of websites: static, dynamic, and single-page applications. Static websites involve serving HTML files directly from a server, which is the most basic method. Dynamic websites, the second approach, generate HTML code on-the-fly in response to user requests, requiring server-side languages and databases. This method was essential for creating user-generated content and dynamic sites like online shops or blogs. The paragraph concludes with an introduction to single-page applications, which provide a seamless, app-like experience without the need for full page reloads, and are driven by JavaScript executing in the browser.
đ ïž When to Use Static, Dynamic, or Single-Page Applications
This paragraph discusses the appropriate use cases for each web development approach. Static sites are ideal for simple, infrequently updated content, such as personal homepages. Static site generators can automate the creation of static HTML files from data sources for more dynamic content that doesn't require real-time updates. The speaker also mentions tools like Gatsby and Netlify, which can turn React apps into static sites while still providing a single-page application experience after the initial load. Dynamic sites are best for online shops and content that requires frequent updates and SEO optimization, as they generate content server-side, making it easily crawlable by search engines. Single-page applications, while offering a reactive and instantaneous user experience, can pose challenges with SEO and performance on slower devices or networks due to the reliance on client-side JavaScript execution.
đ Balancing Performance, SEO, and User Experience in Web Development
The final paragraph wraps up the discussion by summarizing the advantages and disadvantages of each web development approach. Dynamic web pages are praised for their server-side rendering, which is beneficial for SEO andć蜻s the performance load on the client's browser. However, they may not provide the instantaneous feel of a mobile app due to the need to load new pages. Single-page applications offer a highly reactive and smooth user experience but can struggle with SEO and performance issues on less capable devices or networks. Static sites provide finished content, are SEO-friendly, and do not impact client-side performance, but they are less suited for rapidly changing content or user-generated content. The speaker concludes by highlighting the importance of choosing the right approach based on specific project needs and the trade-offs inherent in each method.

Transcripts
hi and welcome to this video in the
modern web development world it's easy
to overlook that we have more ways of
building websites than with just single
page applications and in this video I
want to have a look at all these free
major alternatives we have which they
are and when you might want to use which
alternative for building your website
you'll find an article below the video
where you also read about that and
written form with some additional
information and so on as always if you
liked it would be great if you subscribe
like share and all the usual stuff let's
have a look
so which three different types of
websites do we have how can you build a
modern website the first approach is
deep oldest approach you have a static
website you have an HTML file or maybe a
bunch of HTML files you put these onto a
server and then on that server they are
well served to your users so if you user
enters your cool page calm or your cool
page calm slash about you get the
different HTML files served back and for
this I assume you know how the web
generally works of course if you want to
refresh her on that I do also have a
video an article on that but that is the
oldest approach of building a website
now the second oldest approach would be
that you build a dynamic website and
with that I mean that the HTML code
you're getting back in a response is
rendered on the fly per request on the
server now that is of course required or
that is of course something that was
required in the past because with that
static website approach where you simply
write HTML code and put that onto a
server you couldn't build things like
online shops or blogs so whenever you
needed user generated content or you had
dynamic content that changed a lot where
you want it to display what's in the
shopping cart of a user you can't write
these HTML files in advance right you
won't know what the user puts into his
cart and so so there we needed a
solution where the HTML files are
generated on the server and are then
returned to the users and that means
that you have some server-side language
like nodejs or PHP or Python often all
the way the framework like Express or a
level or Django for Python and the
incoming request would be parsed and
handled by the server side the server
side code would then reach out to a
database fetch some data from there and
then stitch all these pieces together
and build HTML code on the server
of course not from scratch and on its
own but instead you as a developer would
typically define a template and define
where the dynamic spots are in the
template where that dynamic data should
go into typically you would do that
with a templating engine like blade for
laravel or ejs or pug or handlebars for
nodejs and Express and then the server
would do all the heavy lifting and put
all these pieces together to then return
the finished HTML page to the user and
that HTML response then already contains
all the dynamic pieces so it really
allows you to generate different pages
for different requests now the third way
of building websites is then of course
to build a single page application this
is the most modern way and it was
basically inspired by mobile apps the
earth we click around things happen
instantly we never have to wait for a
new page to load
we might see a spinner occasionally
while some data is fetched but in
general we stay in that app experience
and things happen instantly we click
somewhere we instantly get a new page
and we wanted to bring that experience
to browsers as well because with the
dynamic website approach where the
server-side renders all the content of
course every click that loads a new page
results in a new request and then you
response at the page being generated on
a server and although modern engines and
so on are really fast there is of course
a slight delay and we might even need a
new page if no dynamic content changed
if we only went to our about or our
contact page and therefore a single page
applications emerged where are the ideas
that you have one single page an HTML
file that sits on a server and then only
that one file is returned back to the
user but in that one file the core thing
that happens is that a bunch of
JavaScript is loaded and started and
that's JavaScript code then executes
fetches data from a server and builds
the entire HTML page the Dom to be
precise what the user sees on the fly in
the browser so not on a server anymore
but in the browser the huge advantage of
that is of course that since JavaScript
runs in the browser and everything what
we see is rendered in the browser things
do happen instantly there is no
additional request that needs to be sent
to load a new page
occasionally there are requests which
need to be sent to fetch new data but in
the meantime we can show a spinner or
simply delay the navigation by half a
second or anything like that so there
are tricks to then improve the user
experience since everything happens
where the user is in the client so these
are the free approaches and often it
looks like single page applications are
the only way to go nowadays because of
that mobile app like experience for a
lot of applications they are a decent
choice but it turns out that the other
two options are not old and outdated but
have their place as well take static
pages if you have a very simple page
with no dynamic content like your
personal home page where things don't
change that often where you only update
your resume once a year then of course
you can build a bunch of HTML files with
some CSS and maybe a little bit of
JavaScript and deploy that onto a server
and you're done that is all you need so
why wouldn't you use that but even if
you have content that changes more
frequently like for example our website
academy.com where we publish new
articles and we shift things around and
so on then you can use tools called
static site generators where you have
some data source that could be a
database or a bunch of markdown files
and you define how your pages should
generally look like how the frame for
each page looks like and so on and then
this static site generator can be run by
you so you start the generation process
and the generator has a look at all your
data sources fetches the data takes your
predefined
HTML frame so to say inserts the data
and spits out a bunch of pre generated
HTML files not generated on a server but
on your machine or maybe in the cloud
but not as part of an incoming request
but before the page is deployed and then
you deployed that finished static page
onto a server the great thing there is
that there are even solutions like gets
bjs which allows you to build a react
app and then when you build that as a
static site gets me basically visits
every page a user could visit and pre
generates that HTML page by taking a
snapshot but then what you deploy
actually is both the state
Paige but then all's a single-page
application so no matter which page you
load and that's for example the case on
academy.com where we do use gatsby you
load the finished page you load the
finished HTML code but once it is loaded
a single page application takes over and
executes and thereafter you have that
fast mobile app like experience again
now that is the great advantage of
static sites and for a lot of use cases
there are a decent choice now dynamic
pages where the content is generated on
the server also can be great if you're
building an online shop where both
search engine optimization as well as
dynamic content matters or is present
then a dynamic page might be perfect
because single page applications often
have a problem with search engine
optimization because search engine
crawlers don't necessarily wait for the
JavaScript code running in the browser
to complete rendering especially when
you first of all need to fetch some
content from inside your JavaScript code
and their first search engine
optimization can be a problem with
single page applications it's not with
server-side applications where the
content is dynamically generated there
because they are you fetched a finished
page already so the crawler the search
engine crawler sees what the user sees
and that of course is great in addition
to that all the heavy lifting happens on
the server and the advantage of that of
course is that you don't impact the
performance of the app when it runs in
the users browser especially on slower
devices that can be a real thing and
therefore dynamic pages than dynamic
sites where the content is generated on
a per request basis on the server are
not going anywhere they're present
everywhere and they have their their use
case it's not like single page
applications are the only way to go
such server-side applications make a lot
of sense for use cases where you have
data that changes frequently where your
content is highly dynamic whereas search
engine optimization matters and/or where
you want to take performance away from
your users or not take the performance
away but take the performance impact
away from your users and do that on a
server of course you have the downsides
of being a bit less reactive and so on
but there always is a trade-off
for each of these options so to sum it
up we could say a dynamic web page has
the advantage of shipping you the
finished code it also does all the heavy
lifting on the server and therefore your
browser doesn't have to do that
the downside of course is that every new
page has to be loaded and you might need
to wait for that and therefore the
feeling is a bit less mobile app like
and in addition to that from the nent
back-end development is closer connected
because everything happens on the server
and of course you can kind of split the
work but it is definitely close to
connected then if you're building a
single page application where you as the
developer working on that are only
focused on the front-end and people
working on the API you might be talking
to are working on the back-end now a
single page application on the other end
has the advantage of that high
reactivity that great instant feeling
where you have no page reload time times
and where you have a really great user
experience but search engine
optimization can be a real problem a
solvable one but still it can be a
problem and in addition all the heavy
lifting happens in the browser and
especially on slower devices that can be
a problem also on slower networks
because all that javascript code has to
be downloaded to the user first and that
is something you absolutely have to keep
in mind especially when you're targeting
audiences with slower networks or
devices static sites are great because
they also give you the finished content
and therefore they are again great for
search engine optimization you also have
no performance hit because the page
doesn't need to be generated neither on
the server nor in the browser it's just
there already
because you generated it as part of your
development process already and that of
course is great the downside is it's not
really suited for fast change in content
or for a user-generated content because
well everything was pre generated and
you don't want to pre generate your
entire a page every second and setting
up a complete workflow using such a
static site generator can be challenging
if you want to fully automate it
definitely also something you can do and
something you might not need but if you
want to have a process where you publish
a new article and then the whole page is
automatically built and read
Floyd it's all doable but it might
require a little bit more work it's just
something to be aware of now that is my
summary these are the free options and I
hope it became clear when you might want
to use which and what the advantages of
each option are hopefully see you in our
videos to have a great time bye
