WebFundamentals VS lighthouse

8. Web Fundamentals

If you're just starting you dev journey out I wholeheartedly recommend: launchschool.com It will give you a rock solid foundation for JavaScript and the DOM API. Making a good web app it's not just about React. I'm telling that from experience. You should know the DOM API, CSS, HTML and various web idioms. These are some good and free resources for the above: https://javascript.info/ https://developers.google.com/web/fundamentals https://web.dev/ Once you've read the fundamental stuff you continue learning more about React: https://reactjs.org/docs/getting-started.html https://epicreact.dev/ https://overreacted.io/

Yes! I really enjoy the Web Fundamentals series on Web.Dev (used to be HTML5 Rocks). I'm not as familiar with Mozilla resources, but I assume they have similar guides.

Also go thru this: https://developers.google.com/web/fundamentals its a collection of docs on best practices in frontend.

Free resources(I dont think you can learn everything at one place, full stack development covers too many topics): https://www.w3schools.com/ https://web.dev netninja and fireship on youtube https://github.com/topics/epicreact-dev https://zerotomastery.io/resources/ https://digitalocean.com/community/tutorials https://developers.google.com/web/fundamentals

Google's Web Fundamentals covers performance, amongst other things.

7. Web Fundamentals - Best practices for modern web development.

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.
