eleventy 🕚⚡️ VS lighthouse

This post outlines the steps for migrating an existing BlogCFC blog to a JamStack, with a focus on using Eleventy.

I suggest you to try out eleventhy (https://www.11ty.dev/)

Quite simple to start, and a nice system to add some scripting and styles without the requirement of bringing in a framework.

A production flag enables you to run activities in dev or production such as minifying assets, showing draft posts, etc. There isn't a built-in flag or function that comes with eleventy (11ty) specifically for this. However we have this info at our fingertips.

I can't recommend Eleventy enough!

I converted my WordPress blog to Eleventy 4 years ago and never looked back, it's been delightful!

It’s 2024, and you are about to start a new project. Do you reach for React, a framework you know and love or do you look at one of the other hot new frameworks like Astro, Enhance, 11ty, SvelteKit or gasp, plain vanilla Web Components?

The "dev" script is running the eleventy server in dev mode. The details of the script are not important for this discussion, but to round out the background here is an abbreviated version of my package.json:

Eleventy is a fast and powerful SSG that really shines when it comes to pure static site generation because it does not require the loading of a client-side JavaScript bundle in order to serve content.

The irony is using a JavaScript-based static site generator to make the site: https://www.11ty.dev

Then two years ago I needed a more robust SSR system based on React, so I went with GatsbyJS. It's insanely mature and intuitive, but as we all know that community and business is now drying up too. But the framework is still great.

Now everyone sings the praises of NextJS, which can be used for SSR but is intended for applications and active server endpoints. But more complexity doesn't mean better.

I'm keen to try other simple frameworks when the result is a static site. I may give https://www.11ty.dev a shot.

11ty is a lightweight static site generator. I chopped up my HTML and used the 11ty starter template called eleventy-base-blog as the structural foundation for the site.

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.
