HTMLMinifier VS lazysizes

This project uses HTMLMinifier, optipng, and zopfli to create a custom production Elm build pipeline. You can see how I make use of these tools in this build script. Here are the results in case you're interested. I used the same ideas from this project to build and deploy dwayne/elm-conduit, which you can learn more about in my article Yet Another Tour of an Open-Source Elm SPA.

Minification involves removing unnecessary characters, whitespace, and comments from code files. It helps reduce HTML, CSS, JavaScript, etc., file sizes without compromising functionality. Removing redundant elements makes these HTML, JavaScript, and CSS files smaller. Since smaller code files need less internet traffic to transfer, they load faster. Utilizing tools like UglifyJS, Clean-CSS, and HTMLMinifier enhances this process of code reduction. They analyze the code, remove redundant code, and generate optimized files for deployment.

html-minifier works since it has a cli and I can do something like the authors states in the documentation html-minifier --collapse-whitespace inside package.json "scripts": { }, thus I can run the task through the VSCode interface

HTMLMinifier

I found this one https://github.com/kangax/html-minifier which seems to be browser compatible, but impossible to get it to build with my setup (Next.js + typescript).

That's Minifcation and you'd normally thigs like https://github.com/kangax/html-minifier

I am not sure what you'd use this tool for possibly for scraping work but beautiful soup is probably better for that

Use a JavaScript library to implement lazy loading. There are a number of JavaScript libraries available that can help you implement lazy loading, such as Lazysizes and Lozad.

Normally I would write some client-side JS to do this but as this project is solely server-rendered I opted to use a simple tried-and-true library for this: lazysizes.

I recently did some optimizations on my personal website to make the images load “lazily.” In other words it only loads stuff once it hits the viewport. I think that’s what you’re looking for. I tried two techniques:

1. There is an HTML attribute to do just this and it seems to work for iframes too: https://developer.mozilla.org/en-US/docs/Web/Performance/Laz...

2. There is a simple library called “lazy sizes” (https://github.com/aFarkas/lazysizes)

I tried to avoid the lib and use the native HTML… but for whatever reason the lib worked more reliably/effectively in manual tests as well as in my benchmarking via PageSpeed / Lighthouse. YMMV!

lazysizes is better than loading="lazy"

Since browsers support native lazy-loading, do we need libraries like this https://github.com/aFarkas/lazysizes?

Use Lazy loading for below-the-fold images. (You can use different 3rd party libraries like Unveil, lazysizes, etc.)

⚡️ Lazy load images with lazysizes

You can also use this really great library for handling the loading of images in a holistic and well-supported way or you can look at manually implementing the LQIP technique.

And, lazyloading is only for images. If you use e.g. lazysizes you can do anything with it. I'm a digital publisher so I use it for ads and embedded tweets/IGs and so on.
