In what cases is it worth making a SPA application?

Question

JavaScript

Good afternoon. I read the following
in one article :

Single-page applications appeared many years ago, but their use on the Internet is still a rarity. The main reason is that search engines do not recognize them correctly.

From here the question arose, in which cases it is worth using, and in which not.
It is clear that you should not use it in Internet stores.
What about Landings?
Or a portfolio site?

Answer 1

SPA should always be done (if there are resources).
1. We reduce the load
2. Indexing by search engines has long been normal: you need to read the requirements from the PS for a more correct indexing and understanding of the process.
3. The ability to port the SPA application to different platforms if necessary.
4. Ability to create a stand-alone application from the same code.
(I can list endlessly...)

Oh SPA!
How little there is in these letters...
And how much meaning there is in them!
For those
who write the code "beautifully",
And appreciate every moment in life!

Answer 2

A big load - those real 10+k RPS, with proper design, the spa will remove 10-90% of the Admin panel load
- no need to be smart with search engines
And variations
Landing - why is there a spa? There is no interactivity, no settings. Only if you indulge
On the site with a portfolio - you can show off for the sake of it. No practical sense

Answer 3

using them on the Internet is still a rarity

Not so
Google has such developments, but they are still trying to render on the server for search engines.
When we have a small number of template pages. In other cases, it makes no sense.
By the way, the well-known VK is a kind of SPA

Answer 4

use it in closed admin panels and cabinets without any problems. You can't use a search engine there.
well, otherwise you need to get confused on server rendering.

Answer 5

Landing Page is not made to be well indexed. Usually this is an interesting page for the buyer, calling for immediate action. And that's why she and Landing Page, that the traffic to it comes mainly from Google Adwords / Yandex Direct / Banners / Social networks and other paid sources.

Answer 6

If you are making a browser-based (html) game, that is, in fact, you have one page for each user and a bunch of dynamic content. This mess, in principle, cannot be indexed, so you can initially score on search engines and do SPA.
Examples of darkness - fight club and a bunch of analogues, tops, etc., as well as Iframe applications (and games) on VKontakte, Facebook, classmates, many also make them in html.
Such games are promoted either by the internal mechanisms of social networks. networks or advertising.
The library (thematic site) is made according to all the canons for search engines.
