n VS lighthouse

use n or nvm to manage installed node/npm versions.

I have node installed, via n

1 - n is a tool that allows you to easily switch between different versions of Node.js. Follow the official guide in case this does not work for you due to an update or need a command not highlighted below. Here's how you can use n to switch between Node.js versions:

Listing people's recommendations with links below. I'm glad I asked this question. I received a lot of good recommendations. Thanks All! * nvm (https://nvm.sh) - Simple to use and easy to follow instructions with more in-depth configuration for those that need it. Some experienced a slightly slower terminal. Supports nodjs, iojs, and node version per project/directory. * fnm (https://github.com/Schniz/fnm) - Built with speed in mind. It is like nvm, but faster. Also supports node version per project/directory. * Volta (https://volta.sh/) - Looks easy to use and has good documentation. * asdf (https://asdf-vm.com/) - Supports multiple runtimes and tools by adding plugins. Admittedly, is a bit confusing and more than I need right now (Node, Rust, Python, Ruby, etc.) * Homebrew (https://brew.sh/) - Not a version manager but can act like one by installing nvm, fnm, asdf, or others. Some additional configuration may be needed. * Proto (https://moonrepo.dev/proto) - Supports Bun, Deno, Node.js (npm, pnpm, yarn), Rust, and Go. Also good documentation. Setup looks a bit complex to me :/. * n (https://github.com/tj/n) - Supports Node and npm per project. Simple and to the point.

And there are virtual environment; kind of. I just actually started using this, but there's n.

Today, let's find out why you would need multiple versions of Node.js in the first place and how to manage them efficiently with n, a Node.js version manager that is very developer-friendly.

I used n. It was pretty good. I still hated every time I had to change versions and the idea of making dockers for this came with a friend. Thankfully, I don't have that.project anymore

N package since I found it out. Happy for both local pc and servers.

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.
