web.dev VS lighthouse

Before we start creating pages in our application, it's important to understand how Next.js renders content. The framework supports multiple rendering methods including server-side rendering (SSR), static site rendering (SSG), and client-side rendering (CSR). There are many pros and cons to each rendering method (too many to cover in this post) so if these concepts are new to you, Google’s web.dev site has a very good introduction to rendering on the web that can help you understand rendering options.

Probably not, it's the CSS used so far, so if there are elements you've not interacted with, that's an issue. This web.dev article gives some tools you can use https://web.dev/articles/extract-critical-css

I noticed the same for Google's site https://web.dev/

The last article pushed to the feed was "Changes to the web.dev infrastructure" few months ago https://web.dev/blog/webdev-migration

The feed still there but with no updates https://web.dev/feed.xml and on the site you can see new articles published.

Is sad that on a infrastructure revamp of a modern site, the RSS feed was left out of the features list (at least for now).

Upon testing on Firefox and Mi Browser, there was no triggering of the BeforeInstallPrompt event, as expected. However, I noticed that web.dev manages to display a prompt on these browsers, even though they theoretically lack support for the BeforeInstallPrompt event.

In a old web.dev articleI came across the word "Incremental (Re)Hydration" which is linked to a Glimmer.js-Blog post (also called "Incremental Rendering" there) confuses me. Is Incremental (Re)Hydration the same as Progressive (Re)Hydration? Reading the Glimmer-Blog article it seems so, but in the web.devarticle it seems to be something different.

Web.dev newsletter - though it's not a weekly newsletter and it's only content from web.dev (though really high quality content)

Google Core Vitals now represent the most important metrics to focus on when it comes to technical SEO. Google Core Vitals are a set of standardized metrics that Google uses to evaluate the user experience offered by a web page and assign it a technical SEO grade. Several tools exist to measure and report technical SEO performance, but the most reliable is Google Lighthouse.

- referred to https://github.com/GoogleChrome/lighthouse/issues/6512 but didnt see network.disable error - added staticdistdir as per https://github.com/GoogleChrome/lighthouse-ci/blob/main/docs/configuration.md,

There has been discussion about adding a visual indicator to make the mode more obvious, but it has not made it into Chrome devtools!

I haven't tried it, but you might be able to control throttling by using lighthouse to get performance data: https://github.com/GoogleChrome/lighthouse/blob/main/docs/throttling.md

When we implemented the MVP of the fintech app, we had a quite complicated form. At that time, I was still young and inexperienced. And eventually, we realized that our project was slowing down. We had to spend additional hours figuring out the reason. We had many unnecessary re-renders because we ignored basic rules related to props in React. I wanted to do everything possible to avoid such situations in the future. So, I added to the project linters like this and an additional starting configuration to package.json to run why-did-you-render. In short, this plugin issues a warning if something is re-rendered unnecessarily and suggests how to avoid it. Also, we included running Lighthouse in headless mode. Some people say that premature optimizations are bad, but for me, it's a principle: do it right from the start.

You can run a Lighthouse audit in two ways: either on the command line or in a browser. If you want to run audits on the command line, you will first need to install the Lighthouse command:

i wanted to run the lighthouse(lh) docker container on multiple EC2 instances in different regions. I'm thinking of triggering the EC2 instance with the lambda function once the lh container has audited the URL the results will be sent "SUB rest API" which will further update the UI

There's a link to what they mean by mobile network there (https://github.com/GoogleChrome/lighthouse/blob/main/docs/throttling.md) and it says:

Here's the non-psuedo code equivalent that can leverage CompressionStream rather than using a browserified-gzip-library: https://github.com/GoogleChrome/lighthouse/blob/437eb4d757c5...

We use it in Lighthouse for the exact same purpose, a URL #hash full of state. We found that modern browsers support 10mb of data in the hash. https://github.com/GoogleChrome/lighthouse/pull/12509#discus...

Lighthouse: This is an open-source tool developed by Google that allows you to audit the performance of your website. You can use Lighthouse to get a detailed report on your website's Core Web Vitals, as well as other performance metrics. You can run Lighthouse in Chrome DevTools or as a command-line tool.
