Optimization

Of course, this 100/100 is when there is no google adsense code and that here it is only the main page has 100/100 ;)

npm i

How to run

or
yarn dev

It is also possible to generate a sitemap based on html files

Photo optimization

The page consists of the pictures themselves, therefore I load the photos dynamically using 'IntersectionObserver'. In addition, each picture is served in several sizes depending on the width of the window.

To generate such a number of photos I used my script which, based on the original, generates folders with appropriate image sizes -> sharp-images

<picture>
    <source data-srcset="./images/576/img.jpg" media="(max-width: 576px)" class="fade-in" srcset="./images/576/img.jpg">
    <source data-srcset="./images/768/img.jpg" media="(max-width: 768px)" class="fade-in" srcset="./images/768/img.jpg">
    <source data-srcset="./images/992/img.jpg" media="(max-width: 992px)" class="fade-in" srcset="./images/992/img.jpg">
    <source data-srcset="./images/1200/img.jpg" media="(max-width: 1200px)" class="fade-in" srcset="./images/1200/img.jpg">
    <img data-src="./images/1200/img.jpg" class="fade-in" src="./images/1200/lwow/.jpg">
    <noscript><img src="./images/1200/img.jpg"></noscript>
</picture>

Of course, this solution is compatible with SEO - photos are indexed by google. The addition is an essential element <noscript><img src="./images/1200/img.jpg"></noscript>

After optimizing images, the page PageSpeed Insight shows 100/100 in the results.
